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.
