Drive Chain
The drive chain will stretch with use and will
require periodic adjustments. To check the chain
tension, remove the chain guard and measure the
slack.
0.39"-0.79"
10-20mm
The amount of slack in the chain should not
exceed 10-20mm or 0.39"-0.79".
Chain Slack Adjustment
Loosen the axle position lock bolt slightly and turn
the chain adjuster nut to take up the excess slack
in the chain. Once the chain has been adjusted to
the proper tension retighten the axle position
locking bolt.
Inspect the drive and axle sprockets for worn,
damaged or broken teeth. Replace as needed.
Inspect the chain links for damaged, worn or loose
rivets. Repair or replace as needed.
The chain should be kept well lubricated to
prevent excess wear and premature failure. We
recommend that you lubricate the chain every 15
hours of operation, or more frequently if needed,
with a high quality chain lubricant.
