OPERATIONS
1.20 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.
1. Block up pressure plate (I) using wooden block
(B).
2. Remove stabilizer ring from spider assembly

3. Remove blades from trowel arms.
4. Loosen hex head cap screw (A) and remove it

lift levers in place.
6. Clean flats on trowel arm before placing it in
the trowel arm jig (PART# 016863).
7. For PRO 1200 SD series trowels use the medium
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.
