Inspect / Adjust Belt Tension
Belt tension was set in the factory and should not
require adjustments initially. Overtime, the drive
belt may stretch and therefore it should be
inspected regularly and make adjustments as
needed.
1. Disconnect machine from power source!!
2. Open cabinet door to access drive belt.
3. When pushing down into the belt midway
between the pulleys, the belt should flex by
1/8” using moderate finger pressure.
4. If belt tension needs to be adjusted, pull belt
tension handle to the left to release belt
tension, then loosen the jam nut.
5. Adjust belt tension by rotating the motor
positioning nut. Make small, incremental
adjustments and check belt tension with
every 1/2 turn of the nut. To test belt tension,
hand tighten the jam nut and push the
tension lever back to the right to lock the
motor in place. If the belt tension lever is too
difficult to move, reduce belt tension by a bit.
6. Once proper belt tension is set, use one
wrench to hold motor positioning nut in
place and re-tighten the jam nut.
Replace Drive Belt
1. Disconnect machine from power source!!
2. Open cabinet door to access drive belt.
3. Pull belt tension handle all the way to the left
to release the belt.
4. Install a new belt. Rotate the pulleys to make
sure the new belt is sitting properly on the
grooves of the pulleys.
5. Adjust belt tension. See previous section for
details.
