1.15 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 oper-
ation. To operate smoothly the lift lever on all arms must
be adjusted the same to ensure that the trowel is bal-
anced correctly. Adjust trowel arms using optional trow-
el arm jig as described below.
NOTE: Make sure that there is no pitch in the
blades before attempting to remove a
trowel arm.
1. Block up pressure plate (I) using wooden blocks
(B).
2. Remove stabilizer ring from spider assembly

spacer (1-1/4 X 2-1/2) (D).
8. Insert trowel arm into trowel arm jig as shown.
9. Tighten socket head bolts (E) down on the
trowel arm to hold in place.
10. Place carriage bolts (G) on lift lever under the
trowel arm jig (F) as shown.
