1. Determine the agitator shaft size: 7/16" (11.1
mm) or 1/2" (12.4 mm) square. Determine the
size of the shaft adapter (9). Select the size by
placing the adapters onto the built-in agitator
shaft inside the drum. Use the smallest adapter
that will fit. There should only be a small amount
of slip between the adapter nut and the shaft.
2. Attach the shaft adapter (9) to the flat side of
the motor shaft close to the bottom of the motor.
Tighten the set screw (12) securely to 8–9 ft-lbs
(11–12 N•m). NOTE: There is approximately 1/2"
(12 mm) of adjustment travel of the adapter shaft
on the motor shaft if needed for later adjustment.
3. Torque the socket head screw (8) to 12.5–14
ft-lbs (17–19 N•m).
4. Place the threaded housing adapter (6) onto the
motor plate (7) and secure with washers (13) and
screws (11). Torque to 8–9 ft-lbs (11–12 N•m).
5. Align the adapter nut to engage the built-in shaft
in the 55-gallon drum.
6. Slowly screw the unit onto the threads on the
center bung fitting of the 55-gallon drum. Secure
tightly so the motor does not rotate in the bung.

Grounding

Grounding Grounding
The equipment must be grounded to reduce the
risk of static sparking. Static sparking can cause
fumes to ignite or explode. To reduce the risk
of static sparking, the mounting cover and all
electrically conductive objects or devices in the
spray area must be properly grounded.
A ground wire and clamp are not included. For a
ground wire and clamp, order part number 237569.
To ground the agitator, do the following:
• For For models For models 25C528, models 25C528, 25C533, 25C528,
Connect one end of the ground wire (GW) to the
ground connector (GC) on the rim of the drum
cover. Connect the other end of the ground wire to
a true earth ground.
