Read through carefully and understand these instructions
before use.
GENERAL POWER TOOL SAFETY WARNINGS
(For All Power Tools)
WARNING! Read and understand all instructions. Failure
to follow all instructions listed below may result in electric shock, fire
and/or serious personal injury.
9. If operating a power 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)”.
Personal Safety
10. Stay alert, watch what you are doing and use common sense when operating a

The term “power tool” in the warnings refers to your mains-operated (corded) power

tools may result in serious personal injury.
11. Use personal protective equipment. Always wear eye protection. Protective

equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection
1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
2. 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.
3. Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
used for appropriate conditions will reduce personal injuries.
12. 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 energising power tools
that have the switch on invites accidents.
13. Remove any adjusting key or wrench before turning the tool on. A wrench or a
key left attached to a rotating part of the power tool may result in personal injury.
4. Power tool plugs must match the outlet. Never modify the plug in anyway.
Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
5. Avoid body contact with earthed or grounded surfaces, such as pipes,
radiators, ranges and refrigerators. There is an increased risk o electric shock
if your body is earthed or grounded.
6. Do not expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
7. Do not abuse the cord. Never use the cord for carrying, pulling or
14. Do not overreach. Keep proper footing and balance at all times. This enables
better control of the power tool in unexpected situations.
15. 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.
16. 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.
Power Tool Use and Care
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.
8. 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.

17. 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.

18. Do not use tool if switch does not turn it on or off. Any power tool that

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.
ADDITIONAL SAFETY RULES
Service
24. 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.
1. This cut-off machine should only be placed on the ground for operation, never try to
mount it on a table.
2. Wear hearing protection during extended periods of operation, also wear safety
glasses.
3. Use only wheels with maximum operating speed at least as high as “No-Load Speed”
VOLTAGE WARNING:
indicated on the machine nameplate. Be sure to use only fiberglass-reinforced
Before connecting the machine to a power source (receptacle, outlet, etc.), be sure
the voltage supplied is the same as that specified on the nameplate of the machine.
A power source with voltage greater than that specified for the machine can result in
SERIOUS INJURY to the user, as well as damage to the machine. If in doubt, DO
NOT PLUG IN THE MACHINE. Using a power source with voltage less than
wheels.
4. Check the wheel carefully for cracks or damage before operation. Replace cracked or
damaged wheel immediately. Run the tool (with guard) at no load for about a minute,
keeping tool away from others. If wheel is flawed, it will likely separate during this test.
5. Secure the wheel carefully.

6.
Use only flanges specified for this tool.
7.
Be careful not to damage the spindle, flanges (especially the installing surface)
or bolt. Damage to these parts could result in wheel breakage.
8.
9.
Never operate this cut-off machine without guards in place.
22. Always switch off and wait for the wheel to come to a complete stop before moving
workpiece or changing settings.
23. Do not touch the workpiece immediately after operation; it may be extremely hot and
could burn your skin.
Make sure that the workpiece is securely clamped before cutting, and control the
24. This machine should be properly earthed when in use. Be sure to use an earth-leakage
feed speed according to the size, material or diameter of the workpiece. Use a
circuit breaker, with actuating current not more than 30mA and actuating time not more

than 0.1s, if wok area is too hot and wet or poisoned by electric dust.
10. Counterforce will be produced when switching on the machine. Hold the
machine firmly by your right hand and switch on the machine by another one.
11. Make sure the wheel is not contacting the workpiece before the switch is turned
on.
12. Before using this machine on an actual workpiece, let it run for a while. Watch
25. Store wheels in a dry location only.

WARNING! MISUSE or failure to follow the safety rules stated in this instruction
manual may cause serious personal injury.
for vibration or wobbling that could indicate poor installation or a poorly
balanced wheel.
13. Watch out for flying sparks when operating. They can cause injury or ignite
combustible materials.
14. Remove material or debris from the area that might be ignited by sparks. Be
sure that others are not in the path of the sparks. Keep a proper, charged fire
extinguisher closely available.
15. Hold the handle firmly. Keep hands away from rotating parts.
16. Use the cutting edge of the wheel only. Never use side surface.
17. Do not attempt to keep the trigger in the ON position.
18. When cutting with a new wheel, do not press the handle down to the bottom.
That will cause the wheel cut into the ground. Do not press the handle down
more once the workpiece is cut off.
19. This cut-off machine is designed only for dry cutting; do not use any cooling fluid
in cutting operation. Wet or damp may weaken the intensity of the wheel and
invite dangerous.
20. Avoid overload operation. Stop operation immediately if you notice anything
abnormal.
21. If the wheel stops during operation, makes an odd noise or begins to vibrate,
switch off the tool immediately.
