tighten hex cap bolts to take the tension off the
belt.

nut, and washer (B, Fig. 20).

Adjusting Belt Tension
The belt comes adjusted from the factory. If
adjustment is needed:
1. Disconnect the machine from the power
source.
2. Loosen hex cap bolts (A, Fig. 19).
3. Set the belt tension by lightly pressing down on
the motor and tightening the hex cap bolts (A,
Fig. 19).
Note: The weight of the motor should put enough
tension on the belt. You just want to push down
lightly to take up any slack.
