6. Loosen the locking nut on the trowel arm lever, then
turn the trowel arm adjusting bolt until it barely touches
(.010") the fixture adjusting bolt.
7. Once the correct adjustment is made, tighten the lock
nut on the trowel arm to lock it in place.
8. Loosen the locking nuts on the adjustment tool and
remove the trowel arm.
9. Repeat steps for the remaining trowel arms.
Reassembly
1. Clean and examine the upper and lower wear plates
and the thrust collar. Examine the entire spider
assembly. Wire brush any concrete or rust buildup. If
any of the spider components are found to be damaged
or out of round, replace them.
2. Make sure that the bronze trowel arm bushing is
not damaged or out of round. Clean the bushing if
necessary. If the bronze bushing is damaged or worn,
replace it.
3. Reinstall the bronze bushing onto the trowel arm.
4. Repeat steps 2–3 for each trowel arm.
5. Make sure that the spring tensioner is in the correct
position to exert tension on the trowel arm.
6. Insert all trowel arms with levers into the spider plate
(with bronze bushings already installed), using care to
align the grease hole on the bronze bushing with the
grease hole fitting on the spider plate.
7. Lock the trowel arms in place by tightening the hex
head bolt with Zerk grease fitting and jam nut.
8. Reinstall the blades onto the trowel arms.
9. Reinstall the stabilizer ring onto the spider assembly.
10. Lubricate all grease points (Zerk fittings) with premium
lithum-12-based grease, conforming to NLG1 grade #2
consistency.
FLOAT PAN INSTALLATION
Float discs, or pans, attach to the spider arms and allow
early floating on wet concrete and easy movement from
wet to dry areas. They are also very effective at embedding
large aggregates and surface hardeners. There are two
methods for installing float pans: Z-clips or latch pins.

WARNING
Lifting/crush hazard. NEVER lift the trowel
with float pans attached.
WARNING
ALWAYS install float pans either in the work area or
in an area that is next to and level with the work area.
NEVER lift the trowel while float pans are attached.
Installing Float Pans with Z-Clips
Refer to Figure 53 when installing float pans using Z-clips.

Figure 53. Float Pan Installation (Z-Clips)
1. Lift the trowel just enough to slide the pan under the
blades. Lower the finisher onto the pan with the blades
adjacent to the Z-clips.
2. Rotate the blades into position under the Z-clips.
Ensure that the blades are rotated in the same direction
of travel as when the machine is in operation, or use
the engine to rotate the blades into position.
3. Attach the blade tie-downs to the far side of the Z-clip
brackets with the tie-down knobs as shown in Figure 53.
4. Make sure the blade edges are secured under the
Z-clips, and the tie-downs are secured completely over
the edges of the blade bar before the machine is put
back into operation.
