OPERATION
WARNING: It should never be necessary to
force the tool. The weight of the tool applies ade-
quate pressure. Forcing and excessive pressure
could cause dangerous wheel breakage.
WARNING: ALWAYS replace wheel if tool is
dropped while grinding.
WARNING: NEVER bang or hit grinding disc
or wheel onto work.
WARNING: Avoid bouncing and snagging
the wheel, especially when working corners,
sharp edges etc. This can cause loss of control and
kickback.
WARNING: 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.
CAUTION: Always wear safety goggles or a
face shield during operation.
CAUTION: After operation, always switch off
the tool and wait until the wheel has come to a
complete stop before putting the tool down.
CAUTION: ALWAYS hold the tool rmly with
one hand on housing and the other on the side
handle.
Grinding and sanding operation
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° to the workpiece surface.
During the break-in period with a new wheel, do not
work the grinder in forward direction or it may cut into
the workpiece. Once the edge of the wheel has been
rounded off by use, the wheel may be worked in both
forward and backward direction.
