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. 17)
1. Follow the "Pressure Relief Procedure" found in the Operation
section of this manual (section 4.7).
2. Remove filter cap assembly (1).
3. Pull the filter element (2) with support (3) straight out of the
filter body (6).
4. Clean inside the filter body, filter element with support, 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 outside in. Be
sure to clean the filter element thoroughly. Soak in
solvent to loosen hardened paint or replace.

Inspection (Fig. 17)
Inspect all parts of the filter assembly before reassembly.
1. Inspect the support inside the filter element. If the support
has pressure cuts or scratches, replace the filter 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 filter.
1. Place the filter element (2) with support (3) into the filter body
(6).
2. Place the thin PTFE gasket (5) onto the step at the top of the
filter body (6).
3. Place the PTFE O-ring (4) into the groove of the base of the
filter body threads (6).
4. Tighten the filter cap assembly (1) onto the filter body (6).

Maintaining the High Pressure Fluid
Regulator
Regular inspection and lubrication of the regulator are necessary to
keep it working properly.
Cleaning (Fig. 18)
1. Follow the "Pressure Relief Procedure" found in the Operation
section of this manual.
2. Remove the entire high pressure fluid regulator assembly
from the filter assembly.
3.
Turn the regulator knob (1) counterclockwise until it is
removed.
4. Using a wrench on the hex of the cylinder (2), loosen and
remove the cylinder from the regulator housing (3), being
careful not to lose the spring locator (4).
5. Inside the cylinder, remove the spring clip (5), washer (6) and
packing (7).
6. Using a wrench on the flats of the cap (8), loosen and remove
the cap.
7. Using an allen wrench, loosen and remove the two bolts (9)
from the regulator housing. The bar and piston assembly (10)
will come loose. Be careful not to lose the ball valve (11).
8. Thoroughly clean inside the cylinder (2), inside the regulator
housing (3), and the cap (8) with the appropriate solvent.
Clean the washer (6), packing (7) and the bar and piston (10).

Inspection (Fig. 18)
Inspect all parts of the high pressure fluid regulator before
reassembly.
1. Inspect the spring locator (4), packing (7), ball valve (11) and
seat (12). If worn or damaged, replace.
2. Inspect the piston assembly (10). If the piston is worn, replace.
3. Inspect the O-rings (13) in the regulator housing. If worn or
damaged, replace and lubricate with lithium grease.
