Adjusting the support surface for plane grinding
(22).
For plane grinding, the support surface for plane grind-
ing (22) must be aligned parallel to the grinding belt and
face against it over the complete surface.
Loosen screw (25) and fold down the side cover (26).
Loosen the screws (12) and align the support surface
for plane grinding (22). The gap clearance may not
exceed 2 mm max.!(figure 2)
Tighten screws (12) again.
Shut the side cover (26) and tighten screw (25) again.
Adjusting the belt tracking.
Switch the machine on only briefly
and check the belt tracking.
If the grinding belt moves left or
right, adjust the belt tracking with
the starknob bolt (17) until centred.
If the belt tracking cannot be adjusted centred:
Clean the drive wheel (23) and the contact wheel (21)
with compressed air.
Check the drive wheel and the contact wheel for wear,
deformation and damage. Have damaged components
replaced without delay!
Replacing the grinding belt.
Before any work on the machine itself, pull the
mains plug.
Loosen screw (25) and fold down the side cover (26).
Loosen star-knob bolt (11) and remove the grinding
rest and the chip/grinding-dust box (8).
Tilt lever (13) downward to release
the tensioning device.
Remove the old grinding belt.
Before mounting the new grinding
belt, observe the running-direction
indication on the rear of the grinding belt! It mus corre-
spond with the rotation direction of the drive wheel.
Place the grinding belt both around the drive wheel (23)
and around the contact wheel (21).
Tilt lever (13) upward to tension the
grinding belt.
If the grinding belt can not be ten-
sioned sufficiently, the tensioning
device must be readjusted. Loosen
both screws (14), change the position of the tensioning
device and retighten the screws. (figure 6)
Shut the side cover (26) and tighten screw (25) again.
Mount the grinding rest (7) and the chip/grinding-dust
box (8).
Check the gap size of the grinding rest.
Switch the machine on and adjust the belt run.
Operating instructions.

Disengage and fold up the safety pushbutton (15). Press
pushbutton "I" (19).
Switching off:
Fold up safety pushbutton (15). Press pushbutton "0"
(19).
After switching off, the machine runs on for
approx. 50 seconds.
Safety pushbutton:
In situations of danger, press the safety pushbutton to
switch the machine off.
Reversing the speed (only 2H models)
Switch position 1: Low speed
Switch position 2: High speed
The speed may only be reversed with switch (3)
when the machine is stopped.
Overload protection.
In case of continuous high load over a longer period of
time, the machine is switched off. After a cooling-down
period of approx. 15 minutes, the machine is ready for
operation again.
Contact grinding (figures 3+4).
Check if the star-knob bolt (11) is firmly tightened.
Make sure that the top safety cover (1) is secured with
star-knob bolt (4) and the side cover (26) is closed.
Check the gap size of the grinding rest. (figure 1)
Check the position of the support surface for plane
grinding (22). The screws (12) must be in the lower
position.
Check if the spark guard (5) is properly adjusted
andtightened.
Switch the machine on and check the belt run.
Place the workpiece firmly onto the grinding rest.
Guide the workpiece with both hands or fasten it in a
fixture.
Plane grinding (figure 5)
Loosen star-knob bolts (4) and remove the top safety
cover (1).
Ensure that the gap clearance is correctly
adjusted.(figure 2)
Switch the machine on and check the belt run.
