Seat Frame Belt Cam Adjustment
Tools Required: 5/16" Hex Wrench
1-1 Use a 5/16" Hex Wrench to tighten or
loosen the Button Head Belt Adjustment
Bolt.
Note: Turning the screw clockwise increases
tension. Turning the screw counter
clockwise reduces tension (Figure 1).
Note: Increasing tension on the belt tensioning
screw tightens not only the seat frame belt
and proportionately increases tension on
the weight engine drive belt. Excessive belt
tension will cause weight hook to weight
plate hook malfunctions. (Figure 2).
