9. To tighten, press and hold the spindle lock button (2) and
using the pin wrench tighten the outer flange.
10. Turn the new disc by hand, ensuring that it is tight in
the flanges and that it rotates fully and does not wobble
unduly.
11. Run the angle grinder at no load for at least one minute
to ensure the new disc is in good condition. Make sure
you are wearing all the safety gear and that you face the
grinder away from you.
Switching on and off
Before starting the grinder, first ensure the disc, guarding
and the tool is in good condition. Plug the cordset into the
mains socket and set up for the task to be performed.
WARNING. Ensure you are wearing safety glasses.
1. Hold the tool firmly in anticipation of the start up torque.
2. Press and hold the lock-off button (8) and squeeze the
on/off trigger switch (7).
Note. Once the tool has started there is no need to maintain
pressure on the lock-off button.
3. Allow the grinder to start and attain full speed before
bringing the disc to the work piece.
4. To prevent a new grinding disc from digging into
the work piece, first draw the grinder across the work
piece towards the operator. Once the leading edge of
the disc is slightly worn down, grinding can be conducted
in either direction.
5. Once the grinding or cutting is finished, remove the disc
from the work piece. To turn the tool off, release the on/
off trigger switch. The lock-off button (8) will re-engage.
6. The tool will stop. (Please note that the disc continues to
spin for a few seconds even though the switch is turned
off). Keep hands well away from the moving disc.
Do not place the tool down until the grinder has come to
a complete stop.
Holding and guiding the tool
1. Always clamp the work piece.
2. Do not overload the tool so that the disc slows down.
Let the tool do the work rather than applying pressure.
The weight of the tool alone provides sufficient pressure.
3. Cutting discs become very hot when in use. Take care
not to touch them until they have cooled down.
4. Hold the tool securely and make sure that you have full
control at all times.
5. During a cutting operation, maintain an angle of 30 to 40
degrees between the tool and the work piece.
6. During grinding, maintain an angle of 15 to 30 degrees
between the tool and the work piece.
Operation in sander mode
Fitting the Sandpaper
Switch off the tool and disconnect it from the power supply.
1. The GMC grinder/sander/polisher is fitted with a hook &
loop base allowing easy changing of accessories. Ensure
there are no debris left in the hooks & loops of the disc
before fitting accessories.
