OPERATIONS
1.18 Lift Lever Adjustment
Damage to or replacement of a trowel arm can change
the adjustment of the lift lever. This can unbalance the
trowel arms and cause the trowel to wobble during
operation. To operate smoothly the lift lever on all
arms must be adjusted the same to ensure that the
trowel is balanced correctly. Adjust trowel arms using
optional trowel arm jig as described below.
NOTE: Make sure that there is no pitch in the
blades before attempting to remove a
trowel arm.
