Safety pushbutton:
In situations of danger, press the safety pushbutton to
switch the machine off.
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 par-
allelism of the GXR must be adjusted (figure 2+3):
Loosen the two nuts (9).
Readjust screws (9) using a 1/64 in Allen key. Briefly
switch to the belt grinder.
Tighten the two nuts (9) again.
Check the parallelism of the belt tracking. Repeat the pre-
vious 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 neces-
sary when centric belt tracking is not achieved while set-
ting 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.

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 uniformly.
When doing this, the workpiece may not be moved
