Belt sander test. Overview of the best grinders. General selection options
A grinder is a special construction tool designed for abrasive cleaning of the surface of various materials. One of the varieties of such equipment is designed specifically for working with wood. Such grinders, in turn, are also divided into several main types.
What type of equipment to choose
Wood grinders can be classified according to several criteria. There are, for example, professional and household tools on the market. Also, a wood grinder can be:
angular;
straight;
tape, designed for rough surface treatment;
vibration, used for delicate grinding;
eccentric (orbital).
The latter type of equipment can be used not only for final grinding, but also for polishing wooden surfaces.
Professional or household?
When deciding which grinder to choose for a tree, one should first of all consider how often it will be used on the farm in the future. Professional equipment of this type has a very high power and is designed for continuous use and continuous operation throughout the day. These instruments are made from the most quality materials and usually have a lot of power. But such machines are often very expensive.
If the tool will be used only from time to time, as needed, it is worth purchasing, of course, its inexpensive budget household option. In most cases, these machines are designed to be used for no more than 20 hours per month. A household tool for wood should work a maximum of 3 hours a day. In this case, when grinding, you need to take small breaks for 15 minutes.
The power of household equipment is also relatively small. The advantages of such grinding machines ok for wood, consumers attribute primarily their light weight and low cost.
Corner models
It is this type of equipment in domestic conditions that is used most often. In another way, an angle grinder for wood is called a grinder. It can be used to process not only timber, boards and logs, but also any other materials. Bulgarians are used in household not only for grinding surfaces. Very often, they also cut metal or stone with their help.
When choosing an angle grinder, you should pay attention to two main factors: the power of the model and the diameter of the disc.For grinding wood, a grinder is suitable:
power 600-1000 W;
with a disk rotation speed of about 6000 rpm.
straight cars
This equipment is usually used for different kind small jobs requiring high precision. In most cases, straight models of wood grinders are very light in weight. You can hold them during operation, including with one hand. The spindle in this type of equipment is parallel to the body. Such machines are used with nozzles different types. Therefore, with their help, you can perform not only the actual grinding, but also engraving, as well as cutting materials of small thickness.
Tape equipment
A wood grinder of this design can be used both at home and in large workshops. The power and productivity of tape tools are high. But the processing of the material with their use can only be carried out rather rough.
The main elements of the tape equipment mechanism are:
driven and leading rollers;
base sole;
moving tape.
The power of a wood belt sander can be 500-1200 watts. The rollers in such equipment move at a speed of 75-500 meters per minute.
When choosing equipment of this variety, in addition to performance, you should pay attention to such a parameter as the width of the tape. You should also look at which model has additional functionality. Very often, belt grinders are supplemented, for example, with such convenient fixture like a hose for a vacuum cleaner. Also, sometimes equipment of this type comes with a stationary installation and a frame for measuring the depth of grinding.
Vibration Models
Belt sander for woodthus, used for rough surface treatment. For more delicate grinding, vibratory equipment is usually used. Workingoutsolesuchmachines are rectangular.Therefore, such a tool can be used, among other things, for a thoroughgrindingworkpiece corners. During operation, the platform of the machine makes reciprocating movements. Abrasives to the sole of the equipment can be attached with Velcro or clips.
Thus, it is intended specifically for finishing vibrationwood grinder. How to choosesuch a model is a relatively simple matter.Atpurchase of this type of equipmentthe home master should pay attention primarily to ethpower and number of oscillations of the sole per minute. Vibratory grinding machines can also differ in the amplitude of platform displacement. The power of this type of equipment varies between 110-600 watts. At home, devices of 250-300 watts are usually used. The sole of this type of machine can oscillate with a frequency of 6-25 thousand times per minute. The higher this indicator, the more productive the model, of course.
The oscillation amplitude of such equipment is usually in the range of 1.5-5 mm. For the most delicate processing, those machines are suitable for which this indicator is 1.5-2.5 mm. Equipment with a larger amplitude of movement of the platform is usually used for coarser grinding.
Orbital Models
Such a wood grinder works on approximately the same principle as a vibration grinder. The only difference is that the orbital equipment platform moves along a more complex trajectory. That is why when using eccentric machines, the surface is almost perfect. Such devices process materials better than vibration ones. But they are, of course, more expensive.
Sanding machines of any design are often supplemented with dust removal systems. The presence of such a function usually does not have a very serious impact on the cost of equipment. But at the same time, the processing of the material with a tool with a dust collector can be much better. In addition, the eccentric, belt, angle or vibration wood grinder itself, supplemented by such a system, can last much longer (due to cooling through the ventilation holes during operation).
In addition to the design, when choosing such equipment, you should pay attention to:
- its weight (the lighter the machine, the less the hand will get tired);
- performance (processing speed depends on this indicator);
- power;
- casing shape.
The comfort of working with it directly depends on how ergonomic the casing of the model is.
Manufacturers
Equipment such as a grinder is quite expensive. Therefore, when choosing it, among other things, of course, you should pay attention to its brand. You should only buy cars from the best manufacturers having a good reputation. The load on the equipment during operation is significant. Therefore, a bad assembly tool will most likely last a very short time.
Today, many companies supply similar products to the domestic market. But the most popular among domestic consumers is the equipment of such manufacturers as:
Bosch.
Interskol.
Makita.
hitachi.
Which grinder is best for wood: rating
All these companies supply different models to Russia. Some of them are more popular with consumers, others less. The top 5 grinders, according to domestic craftsmen, look like this for 2017:
Makita 9558HN.
Interskol UshM-125/900.

Sanding wood with the Makita 9558HN, according to home craftsmen, is very convenient.The engine is almost inaudible during operation of this machine. Such equipment is relatively inexpensive - an average of about 4,000 rubles. some disadvantage Makita 9558HN consumers consider only a not very convenient power button. Starting and stopping this equipment during grinding is quite difficult.
Tool Interskol UshM-125/900
it another very reliable, according to many consumers,. It is produced in Russia and the build quality is pretty good. The advantages of the equipment "Interskol UShM-125/900" consumers refer primarily to the simplicity of design, reliability, low weight. Sometimes it happens that on the packaging of the grinder the power is indicated quite high. In fact, the equipment does not correspond to the declared indicator. Bulgarian Interskol UshM-125/900 this disadvantage is completely devoid of. With a declared power of 900 W, it cuts ceramic tiles, for example, like butter.
Such models are on the domestic market in the range of 2500-3000 rubles.Their only drawback is overheating when long work.
Bosch GWS 780 C: reviews
Bosch corner cars are being assembled also in Russia. Their main advantage is their low weight. Although the dimensions model Bosch GWS 780 C has very small, the amount of work performed with its use can be simply huge. Also, the advantages of this model are considered smooth start and quick engine shutdown.
Such cars cost about 3.5-5 thousand rubles, depending on the supplier. Disadvantages of Bosch GWS 780 C consumers consider the cable that comes with the kit to be too short and the lack of a case.
Consumer opinion about Makita BO5031 machines
The advantages of this eccentric master models consider small vibration,the presence of a speed controller, quiet operation. Sanding wood with Makita BO50 3 1 can be very high quality and pretty fast. Also, this machine practically does not heat up during prolonged operation. The disadvantages of the model, consumers include a poor-quality dust collector in the kit. When working, you need to additionally connect a vacuum cleaner to the machine. This model costs 5-6 thousand rubles from different suppliers.
Hitachi Equipment
The Japanese company Hitachi also supplies Russian market very high quality equipment.Hand sanders for wood angular Hitachi G13SS2, like almost all other models of this manufacturer, deserved and good consumer reviews primarily for reliability, rather high power and not too much weight. You can change a circle or disc on this equipment without any problems. The machine also has overload protection.
The body of this equipment is considered by most consumers to be very convenient. The hand does not get tired when working with it. To the disadvantages of Hitachi G13SS2 masters include a short cord in the kit and some noise. Such machines cost about 2000-2500 rubles.
The final surface treatment of various parts and structures often involves the use of abrasive materials. The construction market today offers a lot of effective grinding tools. Moreover, even high-performance models are becoming more accessible to ordinary home craftsmen. Such tools, in particular, include a belt tool (LSM), which uses an emery cloth as a working abrasive surface.
What is LSM?
The device consists of a body, inside which contains a compact engine. The dimensions of the tool, as a rule, are small, which determines its ergonomics and ease of operation. The functional part is represented by two rollers, which are located at the ends of the structure. It is fixed on them. At the same time, the tasks of the rollers are divided. One of them acts as a leader (drive), and the second allows you to adjust the transverse positioning of the canvas. Wood should be considered as the target material - such devices cope with it more efficiently than with metal or plastic. So, the average tape in 1 second removes a layer with a thickness of about 1 mm from the workpiece. You can also use the tool in cleaning surfaces from paint and varnish coatings to renew the coating.
Selection according to the main characteristics
The speed of roughing or grinding will depend on the power of the electric motor. Two categories are fundamentally different - models for 500 and 1200 watts. We can say that these are representatives of household and industrial groups, respectively. The power potential of 500 W is suitable as an aid for the occasional refinement of parts. Models with a power of 1000 W or more are used in industries and in the construction industry. High productivity allows high-quality and deep processing of workpiece surfaces for a long time.
Next important parameter- the intensity of the movement of the tape. It depends on it how the operation will be of high quality and uniform. On average, belt machines operate at a speed of 500 to 700 m/min. At the same time, it is not even the maximum processing speed that is important, but the ability to adjust for different ranges. In some cases, 200-300 m/min may be sufficient, and exceeding the speed will not allow you to accurately remove a very thin layer.
What to consider in a feature set?
Some of the useful design features include:
- Smooth start. At the moment of switching on, the current minimization function is activated, which allows you to start processing not with a sharp movement, but with a gradual increase in speed.
- Bounding box. Since the tool involves the provision of manual force on the work area, it is difficult for the operator to maintain the same height of the layer to be removed over the entire area. Therefore, for precise control of the maximum depth, belt grinders are equipped with special stops.
- Dust removal system. In the process of work, large volumes of fine chips and wood dust are inevitably released. For timely elimination and prevention of the spread of waste, some models allow connection to the tool industrial vacuum cleaners. They suck up the generated dust as soon as it is released.
- Maintain high turnover. This is the ability of a power tool to maintain a stable working rhythm when turned on. high speed roller rotation.
Actually, in choosing a tool, it will not be superfluous to initially focus on optimal dimensions abrasive consumable. Two characteristics matter - length and width. As for the first, it expresses the total length of the web, which is wound on spinning rollers. Depending on the model, the length varies from 400 to 600 mm on average. During operation, this parameter will affect the machine's ability to effectively handle long workpieces and blade life in terms of wear. Width directly affects the area of one-time coverage of the target surface. For example, it is advisable to process narrow boards with a tape whose width is 65-75 mm. Sheet large-format material, on the contrary, is more efficiently served by a strip of 100-110 mm. Now you can go to an overview of specific models of belt grinders. The rating below shows the most successful devices from the best manufacturers on the market. hand power tools.
1st place - Makita 9404
The Japanese company regularly occupies the first positions in sales ratings, which can be explained by the high quality of products, their functionality and reliability. These characteristics are appropriate to apply to the grinder modification 9404, the cost of which is about 14 thousand rubles. The tool is equipped with a 1010 W motor, supports speed up to 440 m/min and is equipped with a dust collector. Among competitors, the Makita belt sander of this version may well take first place in terms of build quality, balance of power and functionality. Users, for example, speak positively about the adjustment of speed modes and the maneuverability of the device. Among the small ergonomic advantages, many mention a long cord, comfortable grips on the handle and the presence of several plates in the basic kit (made of cork and graphite).
2nd place - PBS 75 A from Bosch
German manufacturer is a direct competitor to Makita, offering by and large similar products in quality. In this case, the tool is considered less high class. If the aforementioned machine is suitable for semi-professional use, then the PBS 75 A is more likely to have a place in the household. This is also hinted at by the average cost of a model of 8 thousand rubles. For this amount, the owner receives a power potential of 750 W, thanks to which the rollers accelerate to 350 m / min. What operations can belt grinders with these capabilities perform? Operational practice shows that the device copes well with stripping parquet, removing old layers of paint, etc. And, again, the stability of the workflow and endurance are the characteristic features of Bosch tools and Makita. Chinese counterparts and with greater power are unlikely to be able to guarantee the same high quality of grinding while maintaining their own technical resource for a long time.
3rd place - Ryobi EBS800 model
Solution for simple tasks in the household. Ryobi is not as famous as the manufacturers mentioned above, but its products deserve attention, as they combine decent power with an attractive set of options and low cost. Model EBS800 with 800 W motor and speed up to 300 m/min. available for only 4-4.5 thousand rubles. Specifications with previous versions are very close, so what's the difference? As already noted, budget-class belt grinders initially lose to premium counterparts in terms of quality. element base. This option is less reliable and durable, although it can also show noticeable advantages in terms of the convenience of physical handling. There should also be limitations in functionality. The EBS800 lacks soft start, peak load support, and speed control.
4th place - model "Interskol LShM-76/900"
Domestic development for domestic use and also with a small price tag - about 4 thousand rubles. A feature of this model can be called an unusual combination of power and top speed roller rotation - 900 W at 250 m/min. This means that the grinder focuses on rough cleaning of metal surfaces - profiled sheet, car body, various surfaces inventory, etc. Users point to the good performance of the Interskol belt sander, its low weight (3.2 kg) and convenient adjustment. The disadvantages include strong vibrations and noise. Vibrations just do not allow for fine grinding of small parts.
Which manufacturer do you prefer?
The higher the class of the grinder, the more responsible operations can be assigned to it. Therefore, power tools from companies like Bosch and Makita should be chosen for professional use. Elitech, Hitachi and Metabo brands should also be included in this group. If the task is to perform a simple cleaning of small areas, then you can limit yourself to entry-level models. This segment is mainly represented by Russian belt grinders. Reviews, in addition to Interskol devices, also praise the Zubr, Caliber and Enkor models. With an average quality of construction, they give out good power indicators and do not cause any special problems in physical handling.
Is it possible to make LSHM with your own hands?
In the manufacture will require an electric motor, two drums (substitutes for rollers), a frame and mounting hardware. As an engine, you can use a power unit from washing machine. Its average power is about 3 kW, so it will be possible to count on a high-performance mode of operation. As for the bed, then for it you should choose frame structure from thick metal profiles. The main thing in this part is to think over the configuration of interfacing with the engine, drums and carrier platform. Next, you can go to the drums, due to which the belt grinder will process. With your own hands, they can be made from small-format cylinders or wide furniture rollers. Previously, they are turned under the design of the frame and the landing mechanism of the tape itself. The fact is that the diameter in the central region should be several millimeters larger than at the edges. This will ensure stable processing, since the main force will be directed to the canvas in the middle region.
Finally
Usually the transition from mechanical hand tool to electrical analogues is accompanied by a radical change in the principles of processing. In this case, only the working force changes, while the functional consumable retains the characteristics of traditional abrasive materials. Does this mean that such a tool has retained its former processing efficiency? As practice shows, for example, the Makita belt sander, even in semi-professional modifications, gives an effect close to high-tech sandblasting machines. What distinguishes such devices is the softness of the physical impact with the possibility of fine tuning. This is what allows you to clean and even polish sensitive surfaces. wooden blanks without the risk of deep damage by the abrasive belt.
Sanders are good for more than just smoothing lumber. Removing layers of paint, rough metalworking, fine-tuning surfaces before finishing work - this is an incomplete list of processes subject to a lucky grinder.

Before proceeding to familiarize yourself with the capabilities of the most popular models, you should remember two facts:
- each variety has a fairly narrow range of applications. Multifunctionality is peculiar only to renovators, but the volume of work subject to MFPs does not allow them to be considered as the main tool, even for an enthusiastic amateur;
- the opinion that the angle grinder (angle grinder) in skillful hands able to cope with any task (from removing paintwork to sharpening drills and saw chains) is not supported by reliable facts. In 99 cases out of 100, such "universality" is associated with a violation of safety regulations.

4. Interskol PShM-32/130 - 1618 rubles.
Compact tool with a delta-shaped sole for fine sanding in corner joints and on embossed surfaces (solid panel doors, for example). Access to any corner is provided by a tapered sole. The combination of minimum amplitude and low platform oscillation frequency guarantees professional quality:
- when removing single-layer coatings (consumables with large grains are needed);
- when grinding smooth differences (requires a fine sandpaper);
- when dry polishing protective layers of paints and varnishes (with a suitable soft nozzle).
The connection of the consumable with the sole is carried out using the Velcro system (aka Velcro fastener), which securely holds the abrasive sheet during operation. In the absence of the necessary consumables, they can be cut out of sandpaper with a felt layer. For the full operation of the built-in dust removal system, it is necessary to make holes in the self-cut sheets according to the sole pattern. The main thing is not to subject this amateur tool to constant intense loads, and blow out all the holes with compressed air at the end of the work.

Good afternoon to all guests and readers of my review! In this topic, I would like to talk about the rating of the best grinders according to users.
Now in special stores there is no shortage of these machines, but it is rather problematic to make a choice. For this, tops of the best are compiled, not to advertise a specific model, but to help an ignorant person make a choice. That's about such a top 5 best models and I want to tell.
The first place in the top is occupied by the Bort BBS-801N model.
The homeland of this brand is Germany, but the manufacturer, unfortunately, like everything else, is China. Users characterize it as a powerful, decently woodworking, fairly light and productive machine. In addition, there is a lock button and dust collectors. Among its shortcomings, the tape sometimes flies off, the dust collection system is poorly established. Some users came across a low-quality machine that broke down very quickly.
In second place is the Festool CMS-MOD-BS 120 belt grinder. The machine is of excellent German quality, as evidenced by its price. Its cost is approximately 65,000 rubles. Its power is 550 W, weight is 20 kilograms. Tape width 120 mm.
Makita 9404 is in third place in the ranking of grinders. The power of this machine is 1010 W, the weight is almost 5 kilograms. Tape width 1 cm. Users characterize this model as fast, high-quality and quite silent. Of the shortcomings, the sole and adjustment are distinguished. The price of this car ranges from 9,000 to 18,000 rubles.
In fourth place is the Metabo RBE 12-180 grinder. The brand is German, but the country of manufacture is China. It is intended mainly for work with all kinds of metals, pipes made of of stainless steel and so on. Its power is 1200 W, the width of the tape is 40 millimeters, and the weight is about four kilograms. The price is not small - about 60,000 rubles.
And finally, in the last, fifth place is the Dewalt DW433 model. The power of this grinder is 800 W, the belt width is 75 millimeters, and the approximate weight is 6 kilograms. Users note a strong pungent smell while working with this machine, and many do not like the fact that all the dust passes through the engine and the machine quickly fails.
Therefore, before choosing any grinder, it is important to know why you will specifically need it and, based on this, buy one or another model.
Thank you all for your attention!

Belt sander It is customary to call special equipment that is designed for grinding surfaces, cleaning, fitting, marking, giving different forms, leveling and polishing and even sharpening. uncomplicated grinder device similar to the design of an electric planer. Its working element is a grinding tape, which is glued into a ring that is put on the rollers connected to the drive motor. These devices are classified according to the width of the tape, the number of speeds and energy consumed, according to the scope and other indicators.
It is likely that many have already used a belt sander before, and cannot boast of a positive experience. To work with the device was not a burden, you need to follow a few rules and understand the intricacies of using this equipment. To enjoy the work of a grinder, you must be able to choose the right tools and accessories. You need to know, for example, which tapes are best used for working with certain materials, and what power the machine should have to achieve the desired result, etc.
Scope of belt grinders
Among the variety of grinding equipment, being the most popular, tape machines, designed for rough processing of wood and other materials. With their help, they:
- adjustment of cut lines;
- precise cutting;
- leveling, and also make preliminary grinding of rough surfaces;
- forming parts;
- sharpening;
- removal of layers of wood, plastic, glass or metal.
When making a rough surface treatment, tape machines, due to their power and speed of rotation of the working surface, are able to quickly remove wood layers of various thicknesses. To do this, it is necessary to put on the rollers a coarse-grained tape of the width that corresponds to the parameters of the grinder. This equipment does an excellent job of cleaning the surface after processing with a planer, it can align the butt parts of the workpieces and their ends. Grinders can expand door frames without being afraid to accidentally cut off the excess, they do an excellent job of cutting grooves, etc.
Tape machines can quickly and effectively level putty surfaces, clean off old paint. If you need to sand a window frame, door or radiator to the base, then the best device for these purposes you will not find. Due to the technical characteristics, which are very diverse, these devices are used to peel off paint from large areas of car bodies during car repairs. Robust housing allows you to fix the device on a table or stand for processing small size workpieces with manual feed.
Choice of grinder
Choose a grinder necessary depending on the type of work to be done. For example, for processing large areas, it is more appropriate to use devices with wide ribbon, and for processing a narrower surface it is better to use a device with a narrow sanding belt.
Specifications, Consumables
Knowing the technical characteristics of these simple devices will facilitate their selection and help you better perform the planned work. Usually choose a belt sander based on technical specifications such as:
- Power;
- Tape length;
- Tape width;
- Belt speed;
- The ability to adjust the speed;
- The presence of a soft start;
- Manufacturer.
Machine power varies from 350 to 1200 watts and you will need to select a device depending on your needs. Another parameter that affects the quality of work is the rotation of the belt, which is carried out at a linear speed of 75 - 500 m/min. Some models have a speed change function, thanks to which you can do the job better. The smooth start of the electric drive when the device is turned on will also help you improve the quality of work. But there is a large number of models, low cost, in which there are no such additional functions, but the quality of grinding remains on top.

An important element belt sander is sanding belt, without which the device will not be able to perform its functions. It should be noted that one of the defining characteristics is the shape, width, length, grain size of the material from which the abrasive is made and the tape itself. Not only the quality of work, but also the service life of this accessory depends on the combination of all characteristics. In grinders, a looped tape is used, which is based on cotton, nylon, fabric, lavsan, polyester, paper, fiber or other materials.
The abrasive can be made of aluminum dioxide (electrocorundum), silicon carbide or zirconium oxide. To date standard width varies from 30 to 140 mm. The most common is 76 mm. Tape length can be 457 mm, 533, 610 or 620 mm.
An important characteristic is the size of the abrasive particles. For initial rough processing, a tape with a grit of 40 or 60 is used, alignment will require an abrasive with values of 80 or 100, and for finer processing, a material whose grit ranges from 120 to 320 is used. All tapes are marked by color according to their parameters.
All appliances are equipped special device- a dust collector, in which the dust enters the bag with the help of a fan. A vacuum cleaner can be connected to any model, which is able to provide better dust extraction, but some models come with special nozzles.
The subtleties of the grinder, setting and efficiency
Before you start processing wood, you need to familiarize yourself with some of the subtleties that will help you work with the tool. If you need to perform rough processing, it is best to sand at a slight angle to the wood fibers, this will ensure that the layer of the required thickness is quickly cut. In order to make the surface smooth, it is necessary to guide the tool along the wood fibers. Almost all models are designed with a center of gravity shifted closer to the bottom, so pressing the machine during operation is not required if you do not want to make a notch or groove. It is recommended to perform the work with smooth, unhurried circular movements, without plunging the device deep into the wood. Do not abruptly change the speed, pull the tool and change the direction of grinding. To protect the power cord from getting under the work surface, throw it over your shoulder.
Often, when performing grinding work, horseshoe-shaped recesses occur. This is usually due to touching the edge of the work surface. To solve this problem, it is recommended to use new or, in extreme cases, cleaned tapes. The abrasive grit should not exceed 120. It should be borne in mind that in rare cases, the workpiece may remain without scratches and notches along the edges. Therefore, grinding work must be carried out before cutting the element to the final size.
Sanders with a smooth speed change function allow you to work at maximum speed, and you can slow it down in delicate places without stopping work, without turning off the tool.
Despite the simple device, the grinder still requires a small settings. For example, you must always ensure that the directional tape is installed correctly. You can find out about the direction by the arrow, which is drawn on reverse side. Any tape, directional or not, must be centered on the rollers. To do this, turn the machine upside down and plug it into the network. If the belt does not move smoothly, then the machine must be fixed, observing safety precautions, turned on and manipulating the guide roller to center the belt. It is possible to more precisely center the working surface already directly in the process of performing work. Some models are equipped with automatic tracking and do not require manual alignment, although they are more expensive.
Efficiency The use of a tool depends on how fully it is used. With the help of a grinder, you can not only process wood surfaces, but also sharpen cutters, axes, knives, shovels, chisels and other tools. Before working with metal surface it is necessary to thoroughly clean the device from dust, as the metal may spark during operation.
It is necessary to process plywood and all surfaces finished with this material very carefully, at minimum speed.
Sometimes they ask the question - "Which car is better to buy - tape or eccentric?" These are complementary grinders. For primary processing, belt grinding is used, and for finishing grinding, eccentric grinding is used. If there is little work to be done, it is worth choosing an eccentric one, they are more versatile.

If possible, it is better to use a vacuum cleaner instead of a dust collector, which does not cancel glasses and a respirator. And to fix the tool in a comfortable position, it is more expedient to use a special stand, which can be individually selected for any machine.
Care and cleaning of draw frames includes cleaning the tape with a special bar. Usually if you use a tool for processing succulent tree species, the belt will quickly become clogged. To clean the abrasive, it is necessary to fix the device with the working surface up, and then draw the bar along the tape against its movement.
- If the waste dust is collected in a bag, then it must be cleaned after each use of the tool.
- Any device you work with requires some care. Keep your equipment clean!
Safety
Although grinders are safe equipment However, following some rules does not hurt. During any grinding operations, it is necessary to protect the organs of vision and breathing.
- To work with a grinder, you must use headphones, as the noise level that the device emits can harm your health;
- To protect the respiratory organs and eyes, it is necessary to use special masks or respirators and goggles, which are not recommended to be removed until the dust collector is free from dust;
- Before changing the sanding belt or cleaning the dust container, unplug the appliance from the mains;
- Before working with metal, it is necessary to free the room from flammable objects, materials and substances, since the metal being processed can spark;
- When connecting the equipment to the network, you must make sure that the power button is in the off position. For all machines, the power buttons can be fixed in the on position.
Be sure to follow safety precautions, as this will preserve your health and reduce the risk of accidents to a minimum.
