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
•
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

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.
