OPERATION
WARNING:

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:
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.
Grinding and sanding operation
Fig.16
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 ﾟ 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.
