Trowel Arm Adjustment
The adjustment fixture, (Figure 40) is shown with a trowel arm
inserted. As each trowel arm is locked into the fixture, the arm bolt
is adjusted to where it contacts a stop on the fixture. This will
consistently adjust all of the trowel arms, keeping the finisher as
flat and evenly pitched as possible.
1. Locate the trowel arm adjustment tool P/N 9177.
Figure 38. Trowel Arm Adjustment Tool
(Side-View)
Arms with CLOCK-WISE blade
rotation use the fixture arm in the UP
position (A in Figure 39). Arms with
COUNTER CLOCK-WISE blade
rotation use the fixture with the fixture
arm in the DOWN position. (B in
Figure 39).
2. Ensure the fixture arm is in the proper setting (up or down) for
your trowel arm rotation as shown in Figure 39.
3. Next, check the clearance between the round shaft and the
test surface as one of the flat hex sections of the arm rests on
the test surface. Rotate the arm to each of the flat hex sections
and check the clearance of the round shaft. Use a feeler
gauge of .005" (0.127 mm). Each section should have the
same clearance between the round of the trowel arm shaft
and the test surface.
4. If the trowel arm is found to be uneven or bent , replace the
trowel arm.
