Adjusting the grinding rest (8) (figure 1).
Loosen star-knob bolt (9) and adjust the gap size to 2
mm (max.).
Tighten the star-knob bolt again.
Adjusting the support surface for plane grinding
(16).
For plane grinding, the support surface for plane grind-
ing (16) must be aligned parallel to the grinding belt and
face against it over the complete surface.
Loosen screws (4)/(10)/(23) and remove the top and
front safety covers.
Loosen screw (19)/(23) and fold down the side cover
(18).
Loosen screws (3) and adjust the gap clearance
between the stop (5) and the support surface for plane
grinding (16). The gap clearance may not exceed 2 mm
max.! (figure 2)
Tighten screws (3) again.
Close side cover (18) and retighten screws (19)/(23).
Mount the top and front safety covers again and
retighten screws (4)/(10).
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 (1) until centred.
If the belt tracking cannot be adjusted centred:
Clean the drive wheel (17) and the contact wheel (15)
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 (19)/(23) and fold down the side cover
(18).
Tilt lever (11) upward 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 correspond with the rotation direction of
the drive wheel.
Place the grinding belt both around the drive wheel (17)
and around the contact wheel (15).
Tilt lever (11) down to tension the
grinding belt.
Close side cover (18) and retighten
screws (19)/(23).
Check the gap size of the grinding
rest.
Switch the machine on and adjust the belt run.
Operating instructions.
Switching on:
Disengage and fold up the safety pushbutton (12). Press
pushbutton "I" (14).
Switching off:
Fold up safety pushbutton (12). Press pushbutton "0"

Safety pushbutton:
In situations of danger, press the safety pushbutton to
switch the machine off.
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 (9) is firmly tightened.
Make sure that the top safety cover (2) is secured with
star-knob bolt (4)/(23) and the side cover (18) is closed.
Check the gap size of the grinding rest.
Check the position of the support surface for plane
grinding (16). The screws (3) must be in the lower posi-
tion.
Check if the spark guard (7) 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)/(23) and remove the top
safety cover (2).
Ensure that the gap clearance is correctly adjusted.
(figure 2)
Switch the machine on and check the belt run.
Guide the workpiece with both hands and remove it
upwards after the working procedure.
Extraction device
We recommend the use of an extraction device.
The machine can be connected via sleeve (20) to an
exhauster.
