Mounting/replacing the grinding belt.
Before any work on the machine itself, pull the power
plug from the socket outlet.
➤
When starting the operation of the GI150/GI1502H belt
grinder for the first time:
Check the direction of rota-
tion.
➤
Loosen the belt tension lever (11) and assemble a
grinding belt, size 150 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 (11).
➤
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 (23)/(5). 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 GI150/GI1502H belt grinder toward the
right and flip the button upward. The On/Off switch
is located below the red emergency OFF pushbut-
ton.

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 (24).
➤
When the belt tracking can not be adjusted centred,
the parallelism of the GIR must be readjusted (fig. 4):
➤
Loosen the four mounting bolts (12).
➤
Loosen the two bolts (10).
➤
Readjust the alignment mounting screws (27) using
an Allen key, size 4 mm.
➤
Tighten bolts (10) and (12) 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
GIR 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 (Figure 3).
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 (14).
➤
Adjust the contact roller to the required height with
the lever (13).
➤
Tighten the clamping lever again.
➤
Check the adjustment by carrying out a grinding test.

must not come beyond the edges of the grinding
belt.
➤
Always work with uniform feed pressure.
