Adjusting the Ratchet Drive Chain
NOTE: The ratchet drive chain is factory-set for the proper operating tension and should not require
adjustment. The following instructions are provided for reference only, in rare cases where re-adjustment or
replacement may become necessary.
Refer to Figure 4B on the previous page for an illustration of the ratchet drive chain and related components.
The chain should be snug, but not too tight. If the chain is too tight, it may cause excessive wear on the bushings
in the crank arm sprocket (resulting in premature failure).
• To check the ratchet drive chain: push on the middle of the span (either top or bottom)
with one finger (about 20 lbs. pressure) -- the chain should deflect about 3/8 to 1/2 inch. A
straight-edge ruler may be helpful in verifying the proper setting.
• To adjust the ratchet drive chain (refer to Figure 4B) : adjust the bracket position by
loosening the two (2) 1/2" bracket bolts and sliding the bracket forward or backward (to
tighten or loosen) as shown. Following adjustment of the bracket position, verify that the
drive chain is set to the proper tension as specified above.
NOTE: The longer ground drive chain is spring tensioned and is NOT adjustable.
