EHHNK5 RIDE-ON TROWEL • OPERATION MANUAL — REV. #3 (05/03/21) — PAGE 45
Reassembly
1. Examine and clean the entire spider assembly
including the upper and lower wear plates and thrust
collar. Wire brush any concrete or rust buildup. Replace
any damaged or out-of-round spider components.
2. Examine the bronze trowel arm bushings and clean
them if necessary. Replace the bronze bushings if
damaged or out-of-round.
3. Reinstall the bronze bushings onto the trowel arms.
4. Make sure the spring tensioner is in the correct position
to exert tension on the trowel arm.
5. Insert all trowel arms with levers into the spider plate
(with bronze bushings already installed). Align the
grease holes in the bronze bushings with the grease
hole fittings on the spider plate.
6. Tighten the hex head bolts with Zerk grease fittings
and jam nuts to lock the trowel arms in place.
7. Reinstall the blades onto the trowel arms.
8. Install the stabilizer rings onto the spider assemblies.
9. Lubricate all grease points (Zerk fittings) with premium
Lithum 12-based grease, conforming to NLGI Grade 2
consistency.
Float Pan Installation
Float pans
are discs that attach to the trowel blades 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. Refer
to Figure 49 when installing float pans onto finisher blades.
Figure 49. Float Pan Installation
1. Lift the trowel just enough to slide the pan under the
blades. Lower the trowel onto the pan with the blades
adjacent to the Z-clips.
2. Rotate the blades into position under the Z-clips. Make
sure the blades rotate 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 Z-clips with the
tie-down knobs.
4. Make sure the blade edges are secured under the
Z-clips and the tie-downs are secured completely
over the edges of the trowel arms before operating
the trowel.
WARNING
Lifting/crush hazard.
NEVER
lift the trowel
with pans attached.
ALWAYS
install pans
in the work area or in an area next to and
level with the work area.
