that could indicate poor installation or a poorly
balanced wheel.
22. Use the specified surface of the wheel to perform
the grinding.
23. Do not leave the tool running. Operate the tool
only when hand-held.
24. Do not touch the workpiece immediately after
operation; it may be extremely hot and could burn
your skin.
25. Observe the instructions of the manufacturer for
correct mounting and use of wheels. Handle and
store wheels with care.
26. Do not use separate reducing bushings or
adaptors to adapt large hole abrasive wheels.
27. Use only flanges specified for this tool.
28. For tools intended to be fitted with threaded hole
wheel, ensure that the thread in the wheel is long
enough to accept the spindle length.
29. Check that the workpiece is properly supported.
30. Pay attention that the wheel continues to rotate
after the tool is switched off.
31. If working place is extremely hot and humid, or
badly polluted by conductive dust, use a short-
circuit breaker (30 mA) to assure operator safety.
32. Do not use the tool on any materials containing
asbestos.
33. Do not use cloth work gloves during operation.
Fibers from cloth gloves may enter the tool, which
causes tool breakage.

ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing side grip (handle) (Fig. 3)
Country specific
Screw the side grip securely on the position of the tool as
shown in the figure.
Installing or removing wheel guard (For
depressed center wheel , multi disc)
(Fig. 4)
CAUTION:
• The wheel guard must be fitted on the tool so that the
closed side of the guard always points toward the
operator.
Mount the wheel guard with the protrusion on the wheel
guard band aligned with the notch on the bearing box.
Then rotate the wheel guard to such an angle that it can
protect the operator according to work. Be sure to tighten
the screw securely.
To remove wheel guard, follow the installation procedure
in reverse.
Installing or removing depressed center
grinding wheel/Multi-disc (Fig. 5)
WARNING:
• Always use supplied guard when depressed center
grinding wheel/Multi-disc is on tool. Wheel can shatter
during use and guard helps to reduce chances of
personal injury.
Mount the inner flange onto the spindle. Fit the wheel/disc
on the inner flange and screw the lock nut onto the
spindle.
In case of mounting a depressed center grinding wheel/
multi-disc thinner than 4 mm, place the lock nut so that the
protrusion on the lock nut faces outside. Otherwise, place
it so that the protrusion on it fits into the inner diameter of
the wheel/disc.
To tighten the lock nut, press the shaft lock firmly so that
the spindle cannot revolve, then use the lock nut wrench
and securely tighten clockwise. (Fig. 6)
To remove the wheel, follow the installation procedure in
reverse.
WARNING:
Only actuate the shaft lock when the spindle is not
moving.

OPERATION

WARNING:
• It should never be necessary to force the tool. The
weight of the tool applies adequate pressure. Forcing
and excessive pressure could cause dangerous wheel
breakage.
• ALWAYS replace wheel if tool is dropped while
grinding.
• NEVER bang or hit grinding disc or wheel onto work.
