Fig. 28: Remove feed belt
Step 6: Slide on the replacement feed belt, reinstall the
feed belt support screws and washers, and
tighten the grinding head support with the faste-
ners you removed in step 3.
Step 7: Tension the feed belt again and connect the ma-
chine to the power supply.
14.4 Tensioning the feed belt
The tension and guidance of the feed belt must be set
correctly so that the workpiece passes correctly and
safely under the grinding drum and the feed belt is not da-
maged during operation. If the feed belt slips on the rol-
lers, the belt tension must be increased.
If the feed belt moves to one side or the other during ope-
ration, the belt run must be adjusted.
Step 1: Switch off the machine and disconnect the power
plug.
Step 2: Make sure that the feed belt is centered on the
rollers. If this is not the case, loosen the belt
tension equally on both sides of the belt. This is
done by holding the hex nut while turning the
screw (Fig.29) counterclockwise until the belt
can be moved from side to side by hand. Then
center the belt on the rollers.

Step 3: Ensure that the ends of the two clamping screws
extend evenly about 1 ⁄ 4" beyond the hex nut.

If the belt slips during operation, turn the tensioning
screws clockwise a quarter turn at a time until the belt no
longer slips on the rollers. Be careful not to tension the
feed belt too tightly.
14.4.1 Adjust belt run
Run the feed belt at high speed and observe whether it
runs to one side or the other. Make sure that the belt does
not run off the rollers, otherwise the feed belt may be da-
maged.
If the feed belt moves centrally and not to one side or the
other, no further adjustments are required.
If the feed belt moves too much, proceed as follows to
readjust the belt run:
Step 1: Turn the tension screw clockwise on the side the
belt is running to until it moves to the center of
the rollers.
Step 2: Run the belt for a few minutes to make sure it runs
properly on the rollers. Repeat this process if
necessary until the belt is properly centered.
NOTE!
Ensure even tension on the left and right of the feed
belt!
