Contact rollers not in use should always be protected
against damage by placing them in the bracket/magazine
for contact rollers (15).
Mounting/replacing the grinding belt
Before any work on the machine itself, pull the
mains plug.
Only for initial starting-up of the belt grinders
GI150/GI1502H: Check the rotation direction.
Loosen the tensioning device (7) and mount a
150 x 2250 mm long grinding belt.
The running-direction marking of the grinding
belt must correspond with the rotation direction.
Tension the grinding belt with the tensioning device (7).
Move the grinding 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 such that the grinding belt runs centrally. The
exact calibration is carried out while the machine is run-
ning.
Operating instructions.
Close the side covers (17)/(5). When the protec-
tive devices are not mounted, clothing can get
caught by the grinding belt and lead to personal
injury.

Switching on:
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.
(* see operating instructions of the machine)
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 (18).
If the belt tracking can not be adjusted centrally, the
parallelism of the GIR must be adjusted (figure 4):
Loosen the two screws (26).
Adjust the screws (27) using an Allen key, size 4 mm.
Tighten both screws (26) 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 GIR is set parallel ex works. Adjustment is only nec-
essary when centric belt tracking is not achieved while
setting up the drive wheel.
Adjusting the center height (figure 3).
The height of the contact roller is normally adjusted to
the pipe center. However, the adjustment can also be
changed:
Release clamping lever (9).
Adjust the contact roller to the desired height with
lever (8).
Tighten the clamping lever again.
Check the adjustment with a grinding test-run.
Working instructions.
Adjust the belt tracking.
Adjust the center height.
Position yourself aside the machine and pull the feed
lever (29) with your left hand.
Rotate crank (28) 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.
