LUBRICATING THE UPPER PACKINGS

1. Clean out the paint that has seeped past the upper
packings into the packing oil reservoir (fig. 16, item 1)
above the fluid section.
2. Fill the packing oil reservoir 1/2 full with EasyGlide (P/N
0508619) supplied by the factory. This will extend packing
life.
Do not over-fill the reservoir so that it overflows
i
and drips into the paint.

MAINTAINING THE FILTER ASSEMBLY

Clean the filter regularly. Dirty or clogged filters
can greatly reduce filtering ability and cause
a number of system problems including poor
spray patterns, clogged spray tips, etc.

Use care in handling parts as dirt, debris,
scratches, or nicks may prevent o-rings or gaskets
from sealing.
This filter element filters from the inside out. Be
sure to clean the filter element thoroughly on the
inside. Soak in solvent to loosen hardened paint
or replace.
