Installing or removing wheel guard
(For depressed center wheel ,

For tool with locking screw type
wheel guard
► Fig.5: 1. Wheel guard 2. Screw 3. Bearing box
► Fig.6: 1. Wheel guard 2. Bearing box 3. Screw
WARNING:
• When using a depressed center grinding wheel/
Multi-disc, flex wheel, wire wheel brush, cut-off
wheel or diamond wheel, the wheel guard must
be fitted 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 dia-
mond wheel, the ordinary guard can be used.
Follow the regulations in your country.)
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 proce-
dure in reverse.
Installing or removing depressed
center grinding wheel/Multi-disc

Installing or removing abrasive disc
(optional accessory)
► Fig.9: 1. Lock nut 2. Abrasive disc 3. Rubber pad
NOTE:
• Use sander accessories specified in this man-
ual. 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 pres-
sure. 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.
• Avoid bouncing and snagging the wheel, espe-
cially 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 frequently kick and cause loss of control
leading to personal injury.
CAUTION:
• 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
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 workpiece. Once the edge of the wheel has been
rounded off by use, the wheel may be worked in both A
and B direction.
