Safety pushbutton:
In situations of danger, press the safety pushbutton to

Adjusting the grinding belt.
Briefly switch the belt grinder on.
Observe in which direction the grinding belt runs out.
Adjust the belt tracking on the belt until the grinding
belt runs centrally on the contact roller (21).
If the belt tracking can not be adjusted centrally, the
parallelism of the GXR must be adjusted (figure 2+3):
Loosen the two nuts (9).
Readjust screws (9) using a 4 mm Allen key. Briefly
switch to the belt grinder.
Tighten the two nuts (9) again.
Check the parallelism of the belt tracking. Repeat the
previous steps if the result is not satisfactory.
NOTE: The guidance device for the contact roller of
the GXR is set parallel ex works. Adjustment is only
necessary when centric belt tracking is not achieved
while setting up the drive wheel.
Adjusting the center height.
The height of the contact roller is normally adjusted to
the pipe center. However, the adjustment can also be
changed:
Release clamping lever (15).
Adjust the contact roller to the desired height with
lever (14).
Tighten the clamping lever again.
Check the adjustment with a grinding test-run.
Working instructions.
Adjust the belt tracking.
Adjust the center height.
If required, use a length stop (accessories) to precisely
clamp the workpiece.
Position yourself aside the machine and pull the feed
lever (12) with your left hand.
Rotate crank (17) with your right hand to move the
work table laterally and wear off the grinding belt uni-
formly. When doing this, the workpiece may not be
moved beyond the edge of the grinding belt.
Always work with uniform feed pressure.
