WARNING
- To reduce the risk of injury, user must read instruction manual!
General safety rules
WARNING! Read all safety warnings and all instructions. Failure to follow
the warnings and instructions may result in electric shock, fire and / or
serious injury. Save all warnings and instructions for future refer-ence.
The term “power tool” in the warnings refers to your mains-operated (corded)
power tool or battery-operat-ed (cordless) power tool.
Work area safety
- Keep work area clean and well lit. Cluttered or dark areas invite accidents.
- Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
- Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
Electrical safety
- Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Un-modified plugs and matching outlets will reduce risk of electric shock.
- Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
- Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
- Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
- When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
- If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock. NOTE! The term “residual current device (RCD)” may be replaced by the term “ground fault circuit interrupter (GFCI)” or “earth leakage circuit breaker (ELCB)”.
- Warning! Never touch the exposed metal surfaces on gearbox, shield, and so on because touching met-al surfaces will be interfered with the electromagnetic wave, thus causing potential injury or accidents.
Personal safety
-
Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
-
Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
-
Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
-
Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
-
Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
-
Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
-
If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
-
Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
-
Warning! Power tools can produces an electromagnetic field during operation. This field may under some circumstances interfere with active or passive medical implants. To reduce the risk of serious or fatal injury, we recommend persons with medical implants to consult their physician and the medical implant manufacturer before operating this power tool.
Power tool use and care -
The persons with lowered psychophysical or mental aptitudes as well as children can not operate the power tool, if they are not supervised or instructed about use of the power tool by a person responsible for their safety.
-
Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
-
Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
-
Disconnect the plug from the power source and / or the battery pack from the power tool be-fore making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
-
Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
-
Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
-
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
-
Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
-
Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
-
Note that when you operate a power tool, please hold the auxiliary handle correctly, which is helpful when controlling the power tool. Therefore, proper holding can reduce the risk of accidents or injuries.

- Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
- Follow instruction for lubricating and changing accessories.
Safety guidelines during power tool operation
Before commencing operation
- It is obligatory to switch on a power tool to the socket that is properly grounded by grounding contact.
- Use grinding discs safe rotation ratio of which is bigger than rotation ratio of spindle of power tool. Follow manufacturers’ recommendations regarding use of tools and accessories.
- Do not use grinding discs that have cracks, cleavages, distortions, as well as grinding discs causing in-creased vibration of power tool.
- Protect grinding discs from shock, prevent them from greasing.
- Do not use grinding discs dimensions of which (outer diameter and bore diameter) differ from the recommended ones.
- Never work with protection devices dismounted. Damaged protection devices must be replaced immediately.
During operation
- Apply the workpiece to the grinding disc only when the disc reaches its maximum rotation speed.
- Do not use the side surface of grinding disc for grinding.
- Do not stop the motor of power tool when it is energized.
- Beware of recoil (sudden push back) of the workpiece while operating the power tool. Recoil can be caused by non-compliance with operation recommendations, too abrupt apply of the workpiece to the grinding disc, etc. In order to minimize the risk of recoil always follow the recommendations during operation of the power tool.
- During operation of the power tool stay straight and hold the workpiece with both hands on the supporting plate.
- Keep your hands safely distant from the rotating grinding discs and never touch them, otherwise it may result in severe injuries.
- When processing small blanks, use clamping devices.
- During operation watch the position of a power cable (it should always be positioned behind the power tool). Do not allow it to whip around your legs or arms.
- Dust generated during operation may be a hazard to your health, inflammable or explosive; clean your working place in time and use means of individual protection.
- Operation may produce sparks and small metal particles, which can cause injury to the operator or to the bystanders. Always wear means of individual protection (goggles and protective mask), as well as arrange your working place in a proper way.
- Do not work materials containing asbestos. Asbestos is considered carcinogenic.
- If the power supply suddenly cuts during operation, immediately move on / off switch into off in order to prevent accidental starting of the power tool.
- Avoid overheating your power tool, when using it for a long time.
After finishing operation
- • After turning of the power tool off, the grinding disc continues to rotate for some time due to inertia. This is why the power tool should be put aside only after its rotating parts come to a full stop.
• It is strongly prohibited to slow down the rotation of slowing grinding discs by applying force to the side surface of discs.
