Maintaining proper chain tension:
The chain needs to be inspected routinely to maintain proper chain tension.
If the chain develops 1/4" or more of slack it should be tightened using the
procedure below.
Steps to loosen chain:
1. Loosen the jam nuts using a 7/16" wrench.
2. Loosen the adjusting bolts, which are the bolts that hold tension against
the motor, with a 3/16" allen wrench.
3. Loosen the four bolts on the motor using a 1/4" allen wrench so that the
motor can be slid over.
Steps to tighten chain:
1. Tighten the adjusting bolts with a 3/16" allen wrench which actually
pushes the motor back into position. The chain should have no slack.
2. Tighten the jam nuts using the 7/16" wrench so that the motor will not
slide out of position.
3. Tighten the bolts on the motor using the 1/4" allen wrench.
