WARNING
MOVING PARTS HAZARD
Moving parts, such as an impeller blade,
can pinch or amputate fingers. To
reduce risk of injury or damage to equip-
ment, always disconnect power from the agitator
before performing maintenance or service.
WARNING
HOT SURFACE HAZARD
During operation, the motor and the
shaft near the motor can get hot enough
to cause burns if touched. When working
with such equipment, wear appropriate protective
gloves and clothing. Allow the motor to cool for at
least one hour before touching either the motor or
the shaft.
WARNING
TOXIC FLUIDS HAZARD
Improper handling of hazardous fluids or
inhaling toxic fumes can cause ex-
tremely serious injury, even death, due
to splashing in the eyes, ingestion, or bodily con-
tamination. See Toxic Fluids Hazard on page 2.
Agitator and Shaft Removal
1. Make sure power is disconnected from the unit
(see Power Connection ).
2. Rotate the agitator shaft by hand until the drive
quill set screw is accessible through the access
hole in the housing. See Fig. 2, page 5.
