Service

Moving parts, such as an impeller blade, can cut or
amputate fingers. To reduce the risk of serious injury,
always shut off the agitator and disconnect the air line
before moving, checking, or repairing the agitator.
If the unit requires more than installation of a service kit,
it is usually quickest and easiest to send the unit to the
Graco distributor for repair or replacement.
NOTICE
Do not pry with a screwdriver. It will dent the surface of
the plate and body, causing leaks. Use a puller tool,
which will remove the end plate while maintaining the
position of the shaft.
If the vanes need replacing, or foreign material is
present in the motor chamber, an experienced
mechanic may remove the end plate opposite the
drive shaft end.
New vanes should have the edges with cut corners
(or the notched edges, if the vanes are reversible)
pointing toward the bottom of the vane slot.

and lockwashers (25) protruding from the top of the
siphon cover (6).

the siphon tube (4).
