Mount the contact roller.
Before any work on the machine itself, pull the power
plug from the socket outlet.
➤ Loosen both wing bolts (11) and move the spark
guard (10) fully up.
➤ Insert the contact roller (21) with the required diam-
eter into the fork guide and secure it with both lock-

Mounting/replacing the grinding belt.
Before any work on the machine itself, pull the power
plug from the socket outlet.
➤ Loosen the belt tension lever (1) and assemble a
grinding belt, size 75 x 2250 mm.
The direction-of-rotation mark of the grinding belt
must correspond with the direction of rotation.
➤ Tension the grinding belt with the belt tension
lever (1).
➤ Move the sanding belt manually and observe, if it
moves off towards the left or right of the contact
roller.
➤ Adjust the guidance of the drive wheel on the belt
grinder in such a manner that the grinding belt runs
centred. The exact adjustment is made with the
machine running.
Operating instructions.
Wear safety glasses.
Close the cover/side cover (19)/(8). When the protec-
tive devices are not mounted, the grinding belt can
catch hold of your clothing and cause serious injury.
➤ Turn the button of the red emergency OFF pushbut-
ton on the GX75 belt grinder toward the right and
flip the button upward. The On/Off switch is located
below the red emergency OFF pushbutton.
Switching ON:
➤ Push the green button.
Switching OFF:
➤ Push the red button.
In case of an emergency, immediately push the red
emergency OFF pushbutton on the belt grinder.
Adjusting the grinding belt.
➤ Briefly switch on the belt grinder.
➤ Observe the tracking direction of the grinding belt.
➤ Adjust the belt tracking on the belt grinder until the
grinding belt runs centred on the contact roller (21).
When the belt tracking can not be adjusted centred, the
parallelism of the GXR must be readjusted (fig. 2 + 3):
➤ Loosen the four mounting bolts (9).
➤ Readjust the alignment mounting screws (13) using
an Allen key, size 4 mm.
➤ Tighten four mounting bolts (9) again.
Check the parallelism of the belt tracking. Repeat the pre-
vious step if the results are not satisfactory.
NOTE: The guide mechanism for the contact roller of the
GXR is factory-set to be parallel. Readjustment is only
required when centred tracking is not achieved while
adjusting the drive wheel.
Adjusting the centre height.
The height of the contact roller is usually set to the centre
of the pipe. However, the adjustment can be changed:
➤ Unclamp the clamping lever (15).
➤ Adjust the contact roller to the required height with
the lever (14).
➤ Tighten the clamping lever again.
➤ Check the adjustment by carrying out a grinding test.
