10. For tools intended to be fitted with threaded hole
wheel, ensure that the thread in the wheel is long
enough to accept the spindle length.
11. Before using the tool on an actual workpiece, test
run the tool at the highest no load speed for at
least 30 seconds in a safe position. Stop immedi-
ately if there is any vibration or wobbling that
could indicate poor installation or a poorly bal-
anced wheel. Check the tool to determine the
cause.
12. Check that the workpiece is properly supported.
13. Hold the tool firmly.
14. Keep hands away from rotating parts.
15. Make sure the wheel is not contacting the work-
piece before the switch is turned on.
16. Use the specified surface of the wheel to perform
the grinding.
17. Do not use cutting off wheel for side grinding.
18. Watch out for flying sparks. Hold the tool so that
sparks fly away from you and other persons or
flammable materials.
19. Pay attention that the wheel continues to rotate
after the tool is switched off.
20. Do not touch the workpiece immediately after
operation; it may be extremely hot and could burn
your skin.
21. Position the tool so that the power cord always
stays behind the machine during operation.
22. If working place is extremely hot and humid, or
badly polluted by conductive dust, use a short-cir-
cuit breaker (30 mA) to assure operator safety.
23. Do not use the tool on any materials containing
asbestos.
24. Do not use water or grinding lubricant.
25. Ensure that ventilation openings are kept clear
when working in dusty conditions. If it should
become necessary to clear dust, first disconnect
the tool from the mains supply (use non metallic
objects) and avoid damaging internal parts.
26. When use cut-off wheel, always work with the dust
collecting wheel guard required by domestic regu-
lation.
27. Cutting discs must not be subjected to any lateral
pressure.

FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the

• Never actuate the shaft lock when the spindle is mov-
ing. The tool may be damaged.
Press the shaft lock to prevent spindle rotation when
installing or removing accessories.
Switch handle mounting positions (Fig. 2)
The switch handle can be rotated to either 90° left or right
to fit your work needs. First, unplug the tool. Press the

direction). Release the switch trigger to stop. For continu-
ous operation, pull the switch trigger (in the B direction)
and then push in the lock lever (in the A direction). To stop
the tool from the locked position, pull the switch trigger
fully (in the B direction), then release it.
For tool with the lock-off switch
To prevent the switch trigger from accidentally pulled, a
lock lever is provided. To start the tool, push in the lock
lever (in the A direction) and then pull the switch trigger (in
the B direction). Release the switch trigger to stop.
For tool with the lock on and lock-off switch
To prevent the switch trigger from accidentally pulled, a

trigger fully (in the B direction), then release it.
NOTE:
Models GA7030S, GA9030S, GA7040S, GA9040S,
GA7030SF. GA9030SF, GA7040SF and GA9040SF begin
to run slowly when they are turned on. This soft start fea-
ture assures smoother operation.
