CAUTION
When repairing or cleaning the pump, never submerge
the pump in water or allow fluid to enter the pressure
control.
When the pump packings wear, paint begins to leak
down the outside of the pump. Replace the pump
packings at the first sign of leaking, or additional dam-
age to the drive train could occur. Use Pump Repair
Kit 245569 (see List of Kits, page 31).
