Instruction & User Manual
Handle
m
For work safety and convenience use the
auxiliary handle. This can be mounted on
the left or right side, or on the top of the
machine. Choose the position that provides
the most comfortable and safest handling
Guard
m
Fit the guard as shown in the illustration.
Adjust the clamping force of the locking arm
by tightening the hex screw out or in when
the locking arm is unloaded.
Grinding Wheel Assembly
m
Place the inner flange disc over the spindle
with the locking edges facing down and
make sure that the disc and spindle’s edges
mate. The flange disc must not rotate freely,
but must follow the rotation of the spindle.
m
Place the grinding or cut-off disc on the
inner flange disc and align the hole against
the shoulder.
m
Fit the outer flange disc and tighten with the
tightening key. Press and hold in the button
for the spindle lock to prevent the spindle
from rotating during tightening.
m
After fitting or replacing the disc, the grinder
should be test-run at a low speed for a
few minutes, without the disc being placed
against an object. If the disc is damaged it
must be replaced immediately.
Disassembling the grinding wheel can be
performed in inverse order.
NOTE
Power Switch
Ensure the self-locking button is loosened
and the switch is in the ‘off’ position before
the power is turned on.
NOTE
m
On: Press and push the power switch
forward to start the tool, then press down
the switch to lock.
m
Having the switch in the lock position will
mean you don’t have to hold the switch
whilst using the tool.
m
Off: Press and push the power switch
backwardso stop the tool.
Using the pressure release function of the
power switch gives you added safety. Letting
go will make the tool stop itself.
NOTE
Surface Grinding
m
Allow the tool to reach full speed before
touching the tool to the work surface.
m
Apply minimum pressure to the work
surface, allowing the tool to operate at high
speed. Grinding rate is greatest when the
tool is at high speed.
m
Maintain a 20-30 degree angle between the
tool and work surface.
m
Continuously move the tool in a forward
and back motion to avoid creating gouges in
the work surface.
m
Remove the tool from the work surface
before turning it tool off. Allow the tool to
stop rotating before laying it down.
