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.

the tool and wait until the wheel has come to a
complete stop before putting the tool down.

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:
Do not "jam" the wheel or apply
excessive pressure. Do not attempt to make an exces-
sive 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:
Do not start the cutting operation in
the workpiece. Let the wheel reach full speed and care-
fully 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:
During cutting operations, never
change the angle of the wheel. Placing side pressure
on the cut-off wheel (as in grinding) will cause the wheel
to crack and break, causing serious personal injury.
WARNING:
A diamond wheel shall be oper-
ated perpendicular to the material being cut.
For model GA7080 and GA9080, you can rotate the
switch handle.

Operation with wire cup brush
Optional accessory
CAUTION:
Check operation of brush by run-
ning tool with no load, insuring that no one is in
front of or in line with brush.
NOTICE:
Avoid applying too much pressure
which causes over bending of wires when using
the wire cup brush. It may lead to premature
breakage.
Usage example: operation with wire cup brush

Operation with wire wheel brush
Optional accessory
CAUTION:
Check operation of wire wheel
brush by running tool with no load, insuring that
no one is in front of or in line with the wire wheel
brush.
NOTICE:
Avoid applying too much pressure
which causes over bending of wires when
using wire wheel brush. It may lead to premature
breakage.
