Before processing
1. Begin your work with a coarse sandpaper and gra-
dually change to finer grits.
2. The optimal inclination of the workpiece can be adju-
sted.
3. Regularly clean sandpaper with a brush.
4. Replace damaged and worn abrasive belts immedi-
ately.
9.4 Adjustment and set-up work
9.4.1Sand paper mounting (Fig. 10)
By means of clamping lever, the sanding belt is loosened
and tensioned. To place the new sanding belt, the ten-
sion lever must be horizontal to the belt. Fold out the
sanding stopper. Loosen the clamping screw so that the
clamping rod is loosened. Loosen the nut on the extrac-
tion nozzle and pull the extraction nozzle backwards.
Open the protective cover and place the sanding belt on
the rollers. Observe the direction of movement on the in-
side of the sanding belt.
To tension the sanding belt, lay the tension lever again.
Fold up the protective cover and tighten the clamping
screw. Put the suction nozzle and the sanding stopper
back on the sanding belt and tighten the nut.
Sanding belts stretch during operation, a readjustment of
the tape run may be required.
1. Check the smooth sanding belt run with the machine
on. If necessary, adjust with the adjustment handle.
2. Check the free rotation of the sanding belt after each
adjustment and set-up procedure. Start the engine se-
veral times briefly and check the belt run.

9.4.2Sandpaper selection
Choosing the right abrasive grain is extremely important
for optimizing the grinding performance.
Always grind first with a coarse grain and then gradually
change to finer grits. Skip at most one grain level.
Too fine grains and worn abrasive belts can cause burn
marks on the workpiece.
-Grain 60: Surface grinding
-Grain 80: Surfaces and light calibration, most com-mon
grain size
-Grain 100 and 120: Surfaces and fine sanding
-Korn150, 180 and 220: Only fine sanding
9.4.3Grinding unit tilting
The grinding unit can be swiveled 90 ° from vertical to
horizontal. Only swivel the sanding table from the back of
the machine. Pull up the locking lever to release. To pi-
vot, grasp the motor console with your left hand and
grasp the sanding stop with your right hand. To lock,
