arm adjustment bolt with the fixture adjustment bolt.
4. Tighten the locking bolts (Figure 67) to secure the
trowel arm in place.
5. Adjust the bolt distance shown in Figure 67 to match
one of the arms. The other arms will be adjusted to

REASSEMBLY
1. Clean the wear plates and thrust collar, and examine
the entire spider assembly. Use a wire brush to remove
any concrete or rust buildup. Replace any spider
components that are damaged or out-of-round.
2. Inspect the bronze trowel arm bushing, and clean
it if necessary. If the bushing is damaged, worn, or
out-of-round, replace it.
3. Reinstall the trowel arm bushing onto the trowel arm.
4. Repeat steps 2–3 for each trowel arm.
5. Make sure the spring tensioner is in the correct position
to exert tension on the trowel arm.
6. Insert all trowel arms with levers (and bronze bushings
already installed) into the spider plate. Align the grease
holes on the bushings with the grease hole fittings on
the spider plate.
7. Lock the trowel arms in place by tightening the Zerk
grease fitting hex head bolts and jam nuts.

it with the keyway on the spider shaft, and insert it into
the spider assembly.

screw engages the groove in the gearbox main shaft.

Lithum 12-based grease, conforming to NLG1 grade #2
consistency.
LONG-TERM STORAGE
Perform the following procedure when storing the trowel
for more than 30 days.
„ Drain the fuel tank completely, or add STA-BIL
fuel.
„ Run the engine until all gasoline in the carburetor is
completely consumed.
„ Completely drain the oil from the crankcase and refill
with fresh oil.
„ Remove the spark plug. Pour 5–10 cm³ of SAE 30 oil into
the cylinder. Turn the engine ON/OFF switch to the ON
position for a few seconds to distribute the oil. Return the
engine ON/OFF switch to the OFF position, and reinstall
the spark plug.
„ Clean off all external trowel components with a cloth.
„ Cover the trowel and store it away from direct sunlight
in a clean, dry location.
