Installing or removing wheel guard (For
depressed center wheel, flap disc / abrasive cut-
off wheel, diamond wheel)
WARNING:
• When using a depressed center wheel, flap disc, flex
wheel or wire wheel brush, the wheel guard must be fit-
ted on the tool so that the closed side of the guard
always points toward the operator.
• When using an abrasive cut-off / diamond wheel, be
sure to use only the special wheel guard designed for
use with cut-off wheels. (In some European countries,
when using a diamond wheel, the ordinary guard can
be used. Follow the regulations in your country.)
For tool with locking screw type wheel guard (Fig. 4)
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 around 180 degrees coun-
terclockwise. Be sure to tighten the screw securely.
To remove wheel guard, follow the installation procedure
in reverse.
For tool with clamp lever type wheel guard (Fig. 5 &
6)
Pull the lever in the direction of the arrow after loosening
the screw. Mount the wheel guard with the protrusion on
the wheel guard band aligned with the notch on the bear-
ing box. Then rotate the wheel guard around 180°. Fas-
ten it with the screw after pulling lever in the direction of
the arrow for the working purpose. The setting angle of
the wheel guard can be adjusted with the lever.
To remove wheel guard, follow the installation procedure
in reverse.
Installing or removing depressed center grinding
wheel / flap disc (Optional accessory) (Fig. 7 & 8)
WARNING:
• When using a depressed center wheel or flap disc, the
wheel guard must be fitted on the tool so that the
closed side of the guard always points toward the oper-
ator.
Mount the inner flange onto the spindle. Fit the wheel/
disc on the inner flange and screw the lock nut onto the
spindle.
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. To remove the wheel, fol-
low the installation procedure in reverse.
Installing or removing abrasive disc (Optional
accessory) (Fig. 9)
NOTE:
• Use sander accessories specified in this manual.
These must be purchased separately.
Mount the rubber pad onto the spindle. Fit the disc on the
rubber pad and screw the lock nut onto the spindle. 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.
To remove the disc, follow the installation procedure in
reverse.
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 grind-
ing.
• NEVER bang or hit grinding disc or wheel onto work.
• Avoid bouncing and snagging the wheel, especially
when working corners, sharp edges etc. This can
cause loss of control and kickback.
• NEVER use tool with wood cutting blades and other
sawblades. Such blades when used on a grinder fre-
quently kick and cause loss of control leading to per-
sonal injury.
CAUTION:
• Never switch on the tool when it is in contact with the
workpiece, it may cause an injury to operator.
• Always wear safety goggles or a face shield during
operation.
• After operation, always switch off the tool and wait until
the wheel has come to a complete stop before putting
the tool down.
Grinding and sanding operation (Fig. 10)
ALWAYS hold the tool firmly with one hand on housing
and the other on the side handle. Turn the tool on and
then apply the wheel or disc to the workpiece.
In general, keep the edge of the wheel or disc at an angle
of about 15 degrees to the workpiece surface.
During the break-in period with a new wheel, do not work
the grinder in the B direction or it will cut into the work-
piece. Once the edge of the wheel has been rounded off
by use, the wheel may be worked in both A and B direc-
tion.
