Daily Maintenance

Two daily procedures are required for routine operator maintenance
on this sprayer:
A. Lubricating the upper packings.
B. Cleaning the filter screen
A) Lubricating the upper Packings
1. Clean out the paint that has seeped past the upper packings
into the packing oil reservoir (fig. 13, item 1) above the fluid
section.
2. Fill the packing oil reservoir 1/2 full with Piston Lube (P/N 314-
480) supplied by the factory. This will extend packing life.

Do not over-fill the reservoir so that it overflows and
drips into the paint.
B) Cleaning the Filter Screen

day.

screen to the siphon tube.

tube.

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.
Cleaning (Fig. 15)
To clean the filter, perform the following procedure.
1. Follow the "Pressure Relief Procedure" found in the Operation
section of this manual.
2. Remove the filter cap assembly (1) and spring (2).
3. Pull the filter element with ball straight (3) out of the filter
body (4).
4. Clean inside the filter body, filter element with ball, and filter
cap assembly using the appropriate solvent.
i
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.

Inspection (Fig. 15)
Inspect all parts of the filter assembly before reassembly.
1. Inspect the ball inside the filter element. If the ball has
pressure cuts or scratches, replace the filter element.
a.
If the ball is cut, remove the PTFE o-ring (5) using an o-ring pick
and remove the carbide seat (6).
b.
Check the seat for nicks or grooves. If the seat is damaged,
replace.
i
Removal of the PTFE o-ring will damage the o-ring
and require replacement.
2. Remove the spring (2) from the spring guide on the filter cap.
a.
Measure the length of the spring uncompressed. If it measures
less than 3/4" from end to end, replace.
b.
Push the spring back onto the spring guide until it "snaps" back
into position.
3. Inspect the two PTFE gaskets (7,8) and the PTFE o-ring (5) for
deformity, nicks, or cuts. Replace, if needed.
i
The PTFE gaskets, PTFE o-ring, and spring are
packaged in Filter Service Kit P/N 930-050.
