Belt Service
To ensure the efficient transfer of power from the
motors to the blade arbors, the drive belts must be
in good condition and properly tensioned. As the
belts wear with normal use, they will stretch and
need to be re-tensioned. If the belts show signs of
cracking, fraying, or damage, replace them.
Although it is not necessary, removing the cast
iron table from the cabinet could make most belt
servicing tasks safer and easier. Refer to the
Removing Main Table subsection on Page 68
and the Replacing Main Table on Page 69 for
detailed instructions.
Note: Replace the main motor V-belts as a
matched set so that they will wear evenly.

If the V-belts need replacing, lift the motor up
to release the tension, roll the old V-belts off
the pulleys, then install the new V-belts as a
matched set.

Adjust the motor until there is approximately
1
sure between the pulleys, as illustrated in
Figure 139, then re-tighten the motor mount-
ing bolts.
