WARNING:
3. Check the cut-off wheel for visible defects.
Confirm that the cut-off wheel is free of cracks or other visible damages.
4. Confirm that the cut-off wheel is fixed securely to the power tool.
Using the supplied wrench, tighten the clamping bolt on the cut-off wheel mounting shaft to secure the
cut-off wheel.
WARNING:
5. Check the safety covers for proper operation.
Possible accidents such as a cracked cut-off wheel is prevented by this safety cover (wheel cover).
Although it has been fully clamped at the factory prior to delivery, securely reclamp the mounting screws
for safety.
Safety cover and wheel cover are designed to protect the operator from coming into contact with the cut-
off wheel during operation of the tool.
WARNING:
6. Use cut-off wheels whose peripheral speed ratings are over the maximum working
peripheral speed.
When replacing the cut-off wheel, ensure that the replacement cut-off wheel has a designed peripheral
speed in excess of 16000 ft/min (4800m/min).
WARNING:
7. Confirm the stopper pin position.
Confirm that the stopper pin which was used for installtion and removal of the cut-off wheel has returned
to the retract position.
8. Securely fix the cutting material.
Ensure that the material is securely fastened with the vise. If it is not, a serious accident could be caused
if the material comes loose or the cut-off wheel breaks during operation.
9. Check the Power Receptacle.
To prevent overheating, accidental stopping or intermittent operation, confirm that the power plug fits
properly in the electrical receptacle and does not fall out after it is inserted.
Repair or replace the receptacle, if it is faulty.
10. Confirm that the tool's cabtire power cable is not damaged.
Repair or replace the power cord if an inspection of the cabtire cable indicates that it is damaged.
AFTER CONNECTING THE POWER PLUG TO AN APPROPRIATE AC POWER SOURCE, CHECK THE OPERATION
OF THE TOOL, AS FOLLOWS:
11. Trial Run.
After confirming that no one is standing in front of it, step away from the front position and start the power
tool and confirm that no operating abnormalities exist before attempting a cutting operation.
Trial run periods:
When replacing the cut-off wheel ........... Over 3 minutes.
When starting routine work ..................... Over 1 minute.
12. Inspect the rotating stability of the cut-off wheel.
For precise cutting, rotate the cut-off wheel and check for deflection to confirm that the wheel is not
noticeably unstable; otherwise vibration might occur and cause an accident.

Never connect the power tool unless the available AC power source is of the same
voltage as that specified on the nameplate of the tool.
If the power cord is connected to the power source with the trigger switch turned ON,
the power tool will start suddenly and could cause a serious accident.
When the clamping bolt is loose, the cut-off wheel may be damaged when the wheel
axle starts revolving, causing a hazardous condition.
NEVER OPERATE THE POWER TOOL if the safety covers do not function smoothly.
Never use cut-off wheels whose peripheral speed ratings are under the maximum
working peripheral speed.
