WARNING:
• Always use supplied guard when flex wheel is on
tool. Wheel can shatter during use and guard helps
to reduce chances of personal injury.
Follow instructions for depressed center grinding wheel/
Multi-disc but also use plastic pad over wheel. See order
of assembly on accessories page in this manual.
Installing or removing abrasive disc
(optional accessory)
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. Forc-
ing 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, 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
frequently kick and cause loss of control leading to
personal injury.
CAUTION:
• Make the depth of a single cut up to 5 mm. Adjust
pressure on the tool so that the tool does not slow
down during the operation.

• After operation, always switch off the tool and wait
until the wheel has come to a complete stop before
putting the tool down.
• If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.
Grinding and sanding operation
A
B
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.
Operation with diamond wheel
(optional accessory )
CAUTION:
• Do not "jam" the wheel or apply excessive pres-
sure. Do not attempt to make an excessive depth of
cut. Overstressing the wheel increases the loading
and susceptibility to twisting or binding of the wheel
in the cut and the possibility of kickback, wheel
breakage and overheating of the motor may occur.
• Do not start the cutting operation in the workpiece.
Let the wheel reach full speed and carefully enter
into the cut moving the tool forward over the work-
piece surface. The wheel may bind, walk up or kick-
back if the power tool is started in the workpiece.
• A diamond wheel shall be operated perpendicular
to the material being cut.
