TROWEL MAINTENANCE
Clean the trowel daily. Remove all dust and slurry
buildup. Make sure lubrication is performed after any
steam-cleaning.
Trowel Lubrication (Every 8 Hours)
Regular lubrication is required to maintain your trowel in
optimal working condition. Perform the following lubrication
procedure after every 8 hours of use.
1. Locate one of the Zerk grease fittings on the spider
assembly (Figure 58). Remove the Zerk fitting cap
and set it aside.
Figure 58. Spider Lubrication
2. Wipe the Zerk grease fitting clean to prevent abrasive
material from entering the fitting during lubrication.
NOTICE
Refer to the manufacturer's engine manual supplied
with your trowel for more detailed information about
engine maintenance and troubleshooting.

3. Lubricate the Zerk grease fitting with 1 to 1½ shots
of multipurpose grade grease. DO NOT overgrease.
Replace the Zerk fitting cap when finished.
4. Repeat steps 1–3 for the remaining grease fittings on
the spider assembly.
Blade Pitch Adjustment
Perform maintenance adjustment of blade pitch using a
bolt on the trowel arm lever (Figure 59). This bolt is the
contact point of the trowel arm with the lower wear plate
on the thrust collar. The goal of adjustment is consistent
blade pitch and finishing quality.
Figure 59. Blade Pitch Adjustment Bolt
Look for the following indications when determining if blade
pitch adjustment is necessary:
Are blades wearing out unevenly (i.e. one blade is
completely worn out while the others look new)?
Does the machine have a perceptible rolling or bouncing
motion while in use?
Does the guard ring rock up and down relative to the
ground while the machine is in use?
Once it has been determined that blade pitch adjustment
is required, do the following:
1. Place the trowel on a flat, level surface, with blocks
under the main guard ring for support. Any uneven
spots in the floor or debris under the trowel blades will
cause an incorrect perception of adjustment. Ideally,
a 5 ft. x 5 ft. (1.5 m x 1.5 m), 3/4-inch-thick, flat steel
plate should be used.
