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 se-
curely to the power tool. Using the supplied
hex. bar wrench, tighten the clamping bolt on
the cut-off wheel mounting shaft to secure the
cut-off wheel.
WARNING: When the clamping bolt is loose,
the cut-off wheel may be damaged when the
wheel axle starts revolving, causing a hazard-
ous condition.
5. Use cut-off wheels whose peripheral speed
ratings are over the maximum working periph-
eral speed. When replacing the cut-off wheel,
ensure that the replacement cut-off wheel has
a designed peripheral speed.
6. Confirm the stopper position. Confirm that
the stopper which was used for installtion and
removal of the cut-off wheel has returned to
the retract position.
7. 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.
8. Check the Power Receptacle. To prevent
overheating or accidental stopping, confirm
that the power plug fits properly in the elec-
trical receptacle and does not fall out after it
is inserted. Repair or replace the receptacle, if
it is faulty.
9. Confirm that the tool’s 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:
• 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.
• 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.
PRACTICAL APPLICATIONS
WARNING: Never remove or install a work-
piece while the cut-off wheel is rotating to
avoid personal injury.
PROCEDURE TO PLACE THE CUTTING MATERIAL
Place the workpiece material between vise and
press, raise the clutch and push the screw han-
dle to bring vise lightly into contact with the
workpiece material.
Then, turn the clutch down, and securely fix
the workpiece material in position by turning
the Screw Handle.
When the cutting job is com-
pleted, turn the Screw Handle
2 or 3 times to loosen the vise,
and remove the workpiece
material.
SWITCH OPERATION
The trigger switch will
not operate unless the
lock-off button has
been pushed in. When
the trigger switch is
released, the power
goes off and the
lock-off button automatically returns to its
original position, locking the trigger switch.
WARNING: Always release the lock-off but-
ton from the handle when the power tool is
not in use. If the lock-off button is left on in the
handle, serious personal injury could result.
OPERATION INSTRUCTIONS
