1.16 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
equally. All arms should be adjusted at the same time to
ensure that the trowel is balanced correctly. Adjust trowel
arms using optional adjusting tool as described below.
1. Block up pressure plate using wooden blocks (b) and
have blades without contact.
2.
Loosen hex head screws (a) on spider which secures
trowel arm in place (do not remove screws).
3.
Remove trowel arms from spider with lift levers in place
4. Remove blade from trowel arms.
5. Clean all fl ats on trowel arm before placing it in the
adjusting tool (c) to make sure it lies fl at. Clean thor-
oughly using a wire brush and scraper.

The adjusting tool comes with three different size spacers.
Use the shortest spacer (d) when adjusting the T364 and
T464. Use the medium spacer when adjusting the T464SD.
7.
Insert trowel arm into adjusting tool as shown.
8. Tighten socket head bolts (e) down on the trowel arm to
hold it in place.
9.
Move adjusting tool arm (f) over carriage bolts (g) on lift
levers shown.
10.
Loosen the jam nut (h) and adjust the carriage bolt so
that the top of the bolt is just touching and making contact
with the bottom of the adjusting tool.

position disc against blades. Turn disc either to the right or
the left to engage clip angles (b) as shown. Remember the
right hand trowel blades turn counter-clockwise the left-hand
