REPLACING WORN SANDING PAPER
(Ø125MM)
Fig. 3
Before assembly sanding paper always remove
the plug from the mains.
The sandpaper (5) is fixed by Velcro fastener to facili-
tate the replacement.
Simply pull off the sanding paper
Press the new one in the centre of the sanding
sole (6)
Coarse sand-paper (grain 50) removes in general the
bigger part of the material and fine sand-paper (grain
120) is used for the finishing.
REPLACING THE SANDING SOLE
The sole has to be replaced when the Velcro has
been worn out.
Before replacing the sanding sole disconnect the
sander from the mains.
Remove the sandpaper of the sole.
Remove the screws which the sole is fixed to the
sander.
Remove the sole.
Install the new sole on the sander.
Tighten the screws well.
4. USE
OPERATION
Push in the on/off switch (1) to start the machine.
By adjusting the adjusting wheel (8) you can regu-
late the speed.
The ventilating apertures (4) on the housing must
remain clear to ensure optimum cooling of the
motor.
Move the sander over the surface of your work-
piece.
Let loose the same on/off switch to stop the
machine.
The on/off switch can be blocked in position
"ON" by pushing the lock-on button (9) on the
side, while you keep pushing the on/off switch.
The machine can be stopped by briefly pushing
the on/off switch again.
Prevent pushing too much on the machine
during sanding. Excessive sanding pressure does
not lead to increased sanding capacity, but increases wear
of the machine and the sandpaper.
GRIPS
The sander is equipped with two grips: a handle at
the front side and one on the back side.
4
Always hold the sander with both hands on the hand-
les, so as to gain the best possible control over your
sanding operations. Besides you do not risk to beco-
me in touch with the moving parts.
SANDING
The sanding sole of the sander executes small circu-
lar movements. Trough this you will get an even sur-
face without marks.
USER TIPS
Apply long uniform movements to your sander to
obtain the best possible results.
The surface quality after sanding is determined by
the selected grain.
