ADDITIONAL SAFETY GUIDELINES FOR DISC GRINDERS AND POLISHING MACHINES
The tool is intended only for grinding, grinding with sandpaper, grinding with wire brushes and cutting. Read and view all warnings, instructions, figures, and specifications supplied with the power tool. Failure to follow all of the instructions provided below may result in electrocution, fire, or serious injury.
Do not convert this tool to make it fit for a job for which it has not been designed and specified by the manufacturer. Such conversion will result in loss of control and cause serious injuries.
It is prohibited to use the tool as a polishing machine or in any other manner which is non-compliant with the manual.
Performing other works for which the tool is not intended may pose a risk and result in injuries.
Do not use accessories that have not been designed or intended for the work with the tool by the manufacturer. The fact that the accessories can be installed on the tool does not ensure safe operation.
The maximum rotational speed of the accessories must be equal to or greater than the maximum rotational speed of the tool. Accessories with a lower rotational speed than the tool speed can disintegrate into fragments during operation.
The outer diameter and thickness of accessories must be within the size range specified for the tool. It is not possible to properly guard or operate improperly sized accessories.
The size of the hole used for fixing wheels, discs, flanges, and other accessories must match the size of the tool spindle.
Accessories with a fixing hole size not suitable for the tool spindle size will start to vibrate during operation, which may result in the loss of control of the tool.
Do not use damaged accessories. Before each use, examine the condition of the accessories for possible splinters, cracks, abrasions and excessive wear. If any accessories are dropped, check them for damages or install new and undamaged accessories. After checking and installing the accessories, make sure you and all bystanders stand outside the rotation plane of the accessories, then run the tool for one minute at a maximum rotational speed. Damaged accessories will disintegrate during the test.
Wear personal protective equipment. Use face shields, goggles, or safety goggles, depending on the application. If required, use dust masks, hearing protection, safety gloves, and aprons to protect against small pieces of accessories or materials generated during work. The eye protection must allow for stopping any flying debris generated during work. The dust mask must be capable of filtering out dust generated during work. Exposure to noise for too long can result in hearing loss.
Ensure all bystanders keep a safe distance from the work area. Persons entering the work area must wear personal protective equipment. Debris or pieces of damaged accessories which are generated during work can be thrown out of the immediate vicinity of the work area.
When carrying out work during which the disc may come into contact with a live concealed electrical cable or power cord, hold the sander by the insulated handles only. When the disc is in contact with a live wire, it may cause the metal parts of the tool to become live, which may lead to electrocution of the tool operator.
Keep the power cord away from rotating tool parts. If you lose control of the tool, the cord can be cut or caught, and your hand or arm can be drawn into the rotating parts of the machine.
Never put down the tool until the rotating parts have come to a complete standstill. The rotating parts can “catch” the ground and pull the tool out of your control.
Do not turn on the tool while carrying it around. Inadvertent contact with rotating parts can cause your clothes to be caught and pulled in by the tool, which can result in contact with the operator's body.
Clean the tool's ventilation openings regularly. The motor fan draws dust generated during operation inside the tool. Excessive accumulation of metal particles contained in the dust increases the risk of electrocution.
Do not use the tool near flammable materials. Sparks generated during operation may cause a fire.
Do not use accessories that require liquid cooling. Water or coolant may lead to electrocution.
The thread size of the accessories must match the thread of the sander spindle. For flange-mounted accessories, the fixing hole for the accessories must match the size of the fixing flange. Accessories which do not fit into the power tool mount will cause imbalance, excessive vibration and may result in loss of control.
Warnings related to tool kickback towards the operator
The kickback of the tool towards the operator is a sudden reaction to a blocked or clamped: rotating disc, polishing belt, brush or other accessory. Blocking or jamming causes a rotating accessory to stop suddenly, which results in the power tool rotating in the opposite direction to the accessory rotation.
For example, if the grinding wheel is blocked or clamped by the workpiece, the edge of the disc that enters the clamping point may sink into the surface of the material causing the disc to come out or be ejected.
The disc can also be ejected towards or away from the operator, depending on the direction of the grinding wheel movement at the jamming point. Abrasive discs may also break in these conditions.
The tool kickback towards the operator is a result of misuse or failure to follow the guidelines in the manual. This phenomenon can be avoided by following the instructions below.
Use a firm grip on the tool and the correct body posture and hands position to withstand the forces generated by the kickback. Always use an additional handle, if supplied with the tool, to ensure maximum control during the kickback or any unexpected rotation during the tool start. The operator will be able to control the tool rotation or the kickback if appropriate
EN
precautions are taken.
Keep your hands away from rotating tool parts. The rotating parts can come into contact with your hands during kickback.
Do not stand in the area where the tool may move during the kickback. The kickback will direct the tool in the opposite direction to the direction of the abrasive disc rotation at the jamming point.
Pay special attention when working near corners, sharp edges, etc. Prevent the abrasive disc from runout and being jammed. When machining corners or edges, there is an increased risk of the grinding wheel jam, leading to a loss of control or tool kickback.
Do not use discs with a cutting chain for wood processing, segmented diamond discs with circumferential spacing between segments greater than 10 mm or discs with teeth. Such discs cause frequent kickbacks and loss of control of the tool.
Warnings related to grinding and cutting
Use only discs intended for work with a chosen tool and guards designed for a given type of disc. The discs for which the tool is not designed cannot be properly guarded and are not safe.
The convex disc must be mounted in such a way that the grinding surface does not protrude beyond the plane of the protective flange of the guard. An incorrectly mounted disc that protrudes above the guard poses a risk to safety during operation.
The guard must be securely attached to the tool and positioned for maximum safety so that the smallest possible area of the disc is exposed towards the operator. This guard helps to protect the operator from broken disc fragments and prevents accidental contact with the disc.
The disc must be used as intended. For example, do not grind with a cutting disc. Abrasive discs for cutting are designed for circumferential load, lateral forces applied to such a disc may cause it to disintegrate.
Always use undamaged fixing discs, which are of the correct size adapted to the abrasive disc. The correct fixing discs for the abrasive discs reduce the possibility of damage to the abrasive discs. The fixing discs for cutting discs can be different from the fixing discs for abrasive discs.
Do not use worn abrasive discs from larger tools. A larger diameter grinding wheel is not suited for a higher rotational speed of smaller tools and may break.
If you use dual-purpose discs, always use a guard appropriate for the type of work. The use of the wrong guard may lead to the failure to provide the desired degree of protection, which can lead to serious injury.
Warnings related to cutting
Do not “jam” the disc or apply too much pressure. Do not try to cut too deep. Excessive stress of the grinding wheel increases load and susceptibility for twisting or catching the disc in the cut groove, which increases the risk of kickback towards the operator or disc damage.
Do not place your body in the cutting line or behind the rotating grinding wheel. If during operation, the grinding wheel rotates in the direction away from the operator's body, the kickback towards the operator can direct the rotating disc and tool towards the operator.
If the disc is caught or the cut is interrupted for any reason, turn off the tool then keep it at a standstill until the disc rotation stops completely. Never attempt to get the rotating cutting disc out of the groove as it may result in kickback towards the operator. It is recommended to find causes and take appropriate steps to prevent the disc from being caught.
Do not resume cutting in the material. Allow the disc to achieve its nominal rotational speed and only then carefully insert it into the cut groove. The disc may be clamped, pulled out, or kicked back towards the operator if the cut is resumed in the material.
Support panels and other oversized materials to minimise the risk of clamping and kickback towards the operator. Oversized materials tend to bend under their own weight. The supports must be placed under the material close to the cutting line and close to the edge of the material on both sides of the cutting line.
Take special care when performing deep cuts in the walls or other unknown surfaces. A protruding disc may cut through gas pipes, electric cables, or other objects that may cause a kickback towards the operator.
Do not attempt to cut following the shape of an arc. Overloading the disc increases its load and susceptibility to twisting or jamming in the cut groove and the likelihood of kickback towards the operator or disc damage, which can lead to serious injury.
Warnings related to grinding with sandpaper
Use the correct size sandpaper. When selecting a grinding wheel, follow the manufacturer's recommendations. Sand-paper that protrudes well beyond the disc may cause injury, and also increase the risk of jamming, tearing or kickback towards the operator.
Warnings related to the work with the wire brush
Be careful, as wire fragments are also ejected from the brush during normal operation. Do not overload the wires by applying too much pressure to the brush. The wires can easily pierce thin clothing or skin.
If the use of guards is recommended during the work with the wire brush, prevent any contact of the brush with the guard. The wire brush can increase its diameter under load and centrifugal force.
EN
Safety warnings related to polishing
Do not allow any loose part of the polishing disc or fastening cord to rotate freely. Loose and rotating cords can entangle in the fingers or be caught in the workpiece.
EQUIPMENT INSTALLATION
Installation of the abrasive disc guard
To do this, place the disc guard on the cylindrical part of the body around the spindle and use a screw or clamp to fix the guard so that it is attached straight, firmly and securely. Place the abrasive disc guard so that the covered part of the disc is as far away from the hand of the grinder as possible. Never operate the grinder without the disc guard installed correctly!
The grinder is supplied with a guard to ensure proper protection only when sanding with abrasive discs and discs using sandpaper and some wire brushes. The disc must not protrude beyond the side edge of the guard when mounted on the spindle. If any other type of authorised work is carried out, contact the manufacturer for a guard intended for this type of work. When using a Type A guard (for cutting) for grinding with a lateral surface, the guard may interfere with the workpiece causing poor control of the tool. When a Type B guard (for grinding) is used for cutting with a grinding wheel, the risk of exposure to sparks and particles increases, as well as to parts of the wheel in the event of a breakage. When using a Type A (for cutting), Type B (for grinding) or Type C (combined) guard for cutting or grinding of concrete or stone with side surface, the risk of exposure to dust and loss of control due to kickback towards the operator increases. When using a Type A (for cutting), Type B (for grinding) or Type C (combined) guard with a disc wire brush of a thickness that will cause the brush to protrude beyond the guard flange, it may cause the wires to catch the guard, which will cause the wires to break.
Installing the additional handle
Install the handle by screwing it securely to the tool head.
HANDLING OF THE GRINDING DISCS
CAUTION! Install the abrasive discs when the supply voltage is disconnected. Pull the grinder cable plug out of the socket!
Grinding wheel assembly
Disconnect the supply voltage from the tool. Unplug the tool!
During installation, make sure that the edges A (IV) at the bottom of the spindle tip and the fixing flanges overlap thoroughly. Place the upper fixing flange on the spindle. Place the abrasive disc on the spindle and the upper fixing flange. Screw the lower fixing flange on the spindle. Press the spindle lock and tighten the lower fastening flange with a wrench and then release the pressure on the lock button. Insert the power cable plug of the tool into the power outlet, turn on the grinder and observe its operation without any load for about 1 minute. Remove the plug from the socket and check the mounting of the discs.
Positioning of the fixing flanges
Note that the discs at the place of fixing to the spindle may be of different thickness. Depending on the thin abrasive discs used (thickness up to 3.2 mm) or thick ones (thickness over 3.2 mm), the location of the fixing flanges (III) is different. The maximum thickness of the abrasive disc that can be attached to the grinder is 6 mm.
Removing the abrasive discs
Turn off the grinder and pull the plug out of the power outlet. Press the spindle lock and unscrew the lower fixing flange with the fixing wrench and then remove the abrasive disc from the spindle. Clean the spindle and the fixing flanges of dust and other contaminants generated during operation.
Types of grinding wheels
Any grinding wheel reinforced with a plait intended for use with angle grinders with a permissible circumferential speed of at least 80 m/s and fixing and external diameters specified in the technical data table may be used with the grinder.
If the grinding wheel is provided with a non-threaded hole for its assembly, use the fixing flanges. It is also possible to assemble wheels with an external diameter specified in the technical data table, equipped with a M14 threaded hole. In this case, do not use fixing flanges and screw the wheel directly to the spindle, locking it with a button, and tightening the wheel firmly and securely using a flat wrench (not included with the grinder). In the case of wheels enabling the installation of the sandpaper disc with Velcro, only sandpaper discs with the diameter specified in the technical data table should be used. The disc should be placed concentrically on the wheel. The edge of the disc must not project beyond the edge of the wheel. It is also possible to use diamond grinding wheels with the dimensions specified in the technical data table intended for dry cutting and grinding. Perform the assembly in the same manner as in the case of grinding wheels. When using diamond segmented discs, the gap between the segments must not exceed 10 mm, measured at the perimeter of the disc, and the segments must have a negative angle of attack. It is recommended to use grinding wheels made of materials intended for machining a given type of metal.
Refer to the documentation provided with the grinding wheel. Grinding wheels intended for machining stone or diamond grinding wheels for dry working can be used for the machining of ceramic materials. It is recommended to use wire brushes and sandpaper
EN
discs to remove old paint coats from metal parts. It is forbidden to modify the fixing hole, spindle or use reduction rings to adjust the diameter of the fixing hole to the spindle diameter. It is forbidden to use grinding wheels with a fixing hole diameter other than specified in the technical data table. It is forbidden to use grinding wheels with a cutting chain or cutting discs because they increase the risk of tool kickback towards the operator.
Caution! It is forbidden to use discs other than those allowed for use in this manual, even if they can be assembled on the grinder spindle. Improper discs may not withstand the loads generated during the operation of the angle grinder. Damaged or decaying grinding wheels present a risk of serious injury or death.
USING THE GRINDER
Unplug the tool!
Before using the tool, check that the housing and and power cord are not damaged. If any damage is visible, it is forbidden to connect the grinder to the electrical network! Fix the abrasive disc cover and handle. Never work with the grinder without the abrasive disc guard installed!
Select the type of abrasive disc suitable for the type of operation and install the disc on the grinder spindle. The workpiece must be secured, e.g. with vices or clamps, in such a manner that it cannot move during work. The grinder disc rotates at a high speed and, if not properly secured, the material may move uncontrollably during work, which would increase the risk of serious injury. In the case of cutting, support the material being cut on both sides of the cutting line, but in such a way that it does not cause the cutting disc to jam during cutting. Place the supports near the edge of the material being cut and near the cutting line.
Wear eye protection, hearing protectors and protective gloves.
Check that the power switch is in the off position "O". Then insert the plug of the grinder into the mains socket.
Keep an appropriate body position to ensure balance and turn the tool on with the switch. If the power switch is located in the upper or side wall of the grinder body, press the power switch in the rear part of it to turn it on, and then, without releasing the pressure, move it forward in the direction marked with the symbol "I." The power switch may have a hitch that allows it to be locked in this position easier prolonged use. To turn the grinder off, press the power switch on the back of the grinder and allow it to retract. If the power supply is lost while working with the locked power switch, it will only be possible to start work after the power switch has been restored after unlocking and restarting the power switch.
If the grinder is equipped with a power switch located in the lower part of the handle, press and hold the lock button and then press the power switch. Hold the power switch pressed while performing work, but it is not necessary to hold the lock button. Releasing the pressure on the power switch will turn the grinder off. Such a power switch cannot be locked for operation.
Start work by applying the correct surface of the disc to the workpiece:
- when using abrasive discs grind with the side and/or front surfaces,
- in the case of leaf grinding wheels, grind with the side surface so that the sandpaper leaves move parallel to the workpiece,
- in the case of velcro discs enabling the attachment of sandpaper, sanding should be carried out with the side surface,
- in the case of wire brushes, the surface should be worked on with ends of the wires and not with their side surface,
- in the case of cutting discs, cut with the front surface, do not grind with the front surface of the cutting discs.
When grinding with the side surface, keep the grinder at an angle of not more than 30 degrees from the surface to be worked on (V). Move the grinder smoothly to and from yourself. When cutting, the disc should be at a right angle to the cut surface. Do not cut at a different angle. It is forbidden to change the angle of the cutting disc to the workpiece while cutting. Cut only in a straight line. Failure to follow the above recommendations increases the risk of jamming the cutting disc in the workpiece, which can cause the tool to bounce towards the operator, break the disc or fall apart. When cutting, guide the grinder towards the rotation of the disc (VI). When working with the grinder, do not exert too much pressure on the workpiece and do not make sudden movements in order not to cause jamming or cracking and tearing of the abrasive disc. Do not overload the tool, the temperature of the external surface must never exceed 60°C. After the work has been completed, turn off the grinder, remove the hose plug of the grinder from the socket and check the tool. Caution! The disc may be still spinning for some time after turning the grinder off. Wait for the disc to cool down before starting the inspection. During operation, both the disc and the material to be processed can become heated to high temperatures.
Rotational speed control (VII)
The product (YT-821024) enables adjustment of the rotational speed. The adjustment is done by means of a knob. The lower the knob setting, the lower the rotational speed. The lower the rotational speed is recommended when using the product for grinding with wire brushes or sanding with sandpaper. Reducing the rotational speed results in reduced heating of the discs and the material itself, and reduces the amount of dust generated during operation. However, it should be remembered that due to design solutions, the higher the rotational speed, the better the cooling of the product. When operating at reduced speed, more frequent breaks should be used to cool the product.
Remember! When operating with an angle grinder:
Always use an eye guard.
Do not use abrasive discs with a maximum permissible circumferential speed of less than 80 m/s.
Do not use abrasive discs with a maximum permissible rotational speed of less than the grinder's rotational speed.
EN
MAINTENANCE AND OVERHAUL
ATTENTION! Before any adjustment, technical service or maintenance operations unplug the tool. Once the operations have been finished, the technical conditions of the tool must be assessed by means of external evaluation and inspection of the following elements: body and handle, conductor with a plug and deflection, functioning of the electric switch, patency of ventilation slots, sparking of brushes, noise level of functioning of bearings and gears, start-up and smoothness of operation. During the guarantee period, the user cannot dismantle the electric tools or change any sub-assemblies or elements, since it will cancel any guarantee rights. All irregularities detected at overhaul or during functioning of the tools are a signal to have the tool repaired at a service shop. Once the functioning has been concluded, the casing, ventilation slots, switches, additional handle and protections must be cleansed with a stream of air (at a pressure not exceeding 0.3 MPa), with a brush or a cloth without any chemical substances or cleaning liquids. Tools and handles must be cleansed with a clean cloth.
