OPERATION

It should never be necessary to
WARNING:
force the tool. The weight of the tool applies ade-
quate pressure. Forcing and excessive pressure
could cause dangerous wheel breakage.
ALWAYS replace wheel if tool is
WARNING:
dropped while grinding.
NEVER hit the workpiece with the

wheel.
Avoid bouncing and snagging
WARNING:
the wheel, especially when working corners,
sharp edges etc. This can cause loss of control and
kickback.
NEVER use tool with wood cutting
WARNING:
blades and other saw blades. Such blades when
used on a grinder frequently kick and cause loss of
control leading to personal injury.
Continued use of a worn-out

wheel may result in wheel explosion and serious
personal injury.
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
CAUTION:
the tool and wait until the wheel has come to a
complete stop before putting the tool down.
ALWAYS hold the tool firmly with
CAUTION:
one hand on housing and the other on the side
grip (handle).
Grinding and sanding operation
► Fig.27
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.
Operation with abrasive cut-off /
diamond wheel
Optional accessory
WARNING:
excessive pressure. Do not attempt to make an
excessive depth of cut. Overstressing the wheel
increases the loading and susceptibility to twisting
or binding of the wheel in the cut and the possibility
of kickback, wheel breakage and overheating of the
motor may occur.
WARNING:
in the workpiece. Let the wheel reach full speed
and carefully enter into the cut moving the tool
forward over the workpiece surface. The wheel
may bind, walk up or kickback if the power tool is
started in the workpiece.
WARNING:
change the angle of the wheel. Placing side pres-
sure on the cut-off wheel (as in grinding) will cause
the wheel to crack and break, causing serious per-
sonal injury.
WARNING:
ated perpendicular to the material being cut.
For model GA7080 and GA9080, you can rotate the
switch handle.
