Adjust the guidance of the drive wheel on the belt grinder
such that the grinding belt runs centrally. The exact cali-
bration is carried out while the machine is running.
Operating instructions.
Close the side covers (17)/(5). When the protective
devices are not mounted, clothing can get caught
by the grinding belt and lead to personal injury.
GI150/GI1502H*
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 par-
allelism 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 pre-
vious 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 necessary
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 uniformly.
When doing this, the workpiece may not be moved
beyond the edge of the grinding belt.
Always work with uniform feed pressure.

REMARK: The sum of the measured emission value and
respective measuring inaccuracy represents the upper
limit of the values that can occur during measuring.
Wear hearing protection!
Measured values determined in accordance with the cor-
responding product standard (see last page in this Instruc-
tion Manual).
Troubleshooting
Malfunction Cause/Corrective Action
Heavy running noise Center height not uniform;
adjusting center height
Discoloration of pipe Feed pressure too high;
reduce feed pressure
Heavy burr formation Grinding belt worn; replace
grinding belt
