Lift Lever Adjustment
Lift Lever Adjustment Procedure
Damage to and/or replacement of a trowel arm can change the adjustment of the
lift lever. This can unbalance the trowel arms and cause the riding trowel to wobble
during operation. To operate smoothly the lift lever on all trowel arms must be adjust-
ed the same to ensure that the riding trowel is balanced correctly.
Adjusting the trowel arms is accomplished by using the optional trowel
arm alignment jig (Part #: 016863).
The service manual that is included with
the alignment jig describes in detail the steps to preform this procedure and to
check the flatness and straightness of the trowel arms.

aligned.
1. Block up pressure plate [A] using a wooden block.
