Maintenance
6.2 Maintaining the Filter Assembly
Clean the lter regularly. Dirty or clogged lters can greatly reduce
ltering ability and cause a number of system problems including
poor spray patterns, clogged spray tips, etc.
Cleaning (Fig. 17)
1. Follow the “Pressure Relief Procedure” found in the Operation
section of this manual (section 4.7).
2. Remove lter cap assembly (1).
3. Pull the lter element (2) with support (3) straight out of the
lter body (6).
4. Clean inside the lter body, lter element with support, and
lter cap assembly using the appropriate solvent.

Use care in handling parts as dirt, debris, scratches,
or nicks may prevent o-rings or gaskets from sealing.
This lter element lters from the outside in. Be
sure to clean the lter element thoroughly. Soak in
solvent to loosen hardened paint or replace.

Inspection (Fig. 17)
Inspect all parts of the lter assembly before reassembly.
1. Inspect the support inside the lter element. If the support
has pressure cuts or scratches, replace the lter element.
2. Inspect the two PTFE gaskets (4, 5) for deformity, nicks, or
cuts. Replace, if needed.
Reassembly (Fig. 17)
After cleaning and inspecting all parts, reassemble the lter.
1. Place the lter element (2) with support (3) into the lter body
(6).
2. Place the thin PTFE gasket (5) onto the step at the top of the
lter body (6).
3. Place the PTFE O-ring (4) into the groove of the base of the
lter body threads (6).
4. Tighten the lter cap assembly (1) onto the lter body (6).
