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.
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
•
saw blades. 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.
