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
•
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:
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.

ALWAYS hold the tool firmly with one hand on rear
handle 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.
