WARNING
SKIN INJECTION HAZARD
Spray from the gun, hose leaks, or ruptured components can inject fluid into your body and cause
extremely serious injury, including the need for amputation. Fluid splashed in the eyes or on the skin
can also cause serious injury.
D Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate surgi-
cal treatment.
D Do not point the gun at anyone or at any part of the body.
D Do not put your hand or fingers over the spray tip.
D Do not stop or deflect leaks with your hand, body, glove or rag.
D Follow the Pressure Relief Procedure on page 5 whenever you: are instructed to relieve pres-
sure; stop spraying; clean, check, or service the equipment; and install or clean the spray tip.
D Tighten all fluid connections before operating the equipment.
D Check the hoses, tubes, and couplings daily. Replace worn, damaged, or loose parts immediately.
Permanently coupled hoses cannot be repaired; replace the entire hose.
TOXIC FLUID HAZARD
Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin,
inhaled, or swallowed.

D Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,
state and national guidelines.
D Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and
solvent manufacturer.

Installation
Install a suitable adapter in the 3/8 npt filter inlet
(Model 240183 has a 1/2 npt inlet). Then install the
filter downstream from the pump fluid outlet.
Install a suitable adapter in the filter outlet. Models
236789, 237480, 237481, 238782, 241107, and
248851 have a 3/8 npt outlet, and Models 240183,
24U609, and 24F658 have a 1/2 npt outlet; the others
have a 1/4 npt outlet. Connect the spray hose to the
filter outlet.

Operation
Pressure Relief Procedure
WARNING
SKIN INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
D are instructed to relieve the pressure,
D stop spraying,
D check or service any of the system equipment,
D or install or clean the spray tip.
1. Lock the gun trigger safety.
2. Turn off the power to the pump.
3. Close any bleed-type master air valves.
4. Unlock the gun trigger safety.
5. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
6. Lock the gun trigger safety.
7. Open the system drain valve(s), having a container
ready to catch the drainage.
NOTE: Some models are supplied with a drain valve
(12). Refer to the parts list for your model.
8. Leave the drain valve(s) open until you are ready
to spray again.
If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above, very slowly loosen the
tip guard retaining nut or hose end coupling and relieve
pressure gradually, then loosen completely. Now clear
the tip or hose.

Cleaning the Filter
Dried paint sediment can clog the filter screen and
greatly reduce filtering ability. Dried paint also makes
the filter difficult to remove. Clean the filter regularly;
daily if needed, following the procedure below.
CAUTION
To avoid damaging parts, never force them apart. If
any parts are stuck tightly together, soak them in a
compatible solvent before disassembling them.
Be careful not to drop or damage the filter housing
and bowl. Dirt, paint sediment, nicks or scratches
may prevent the o-ring (3) from seating properly.
CAUTION
Improper assembly of the filter support, screen and
spring will prevent filtering and damage parts.
11. Replace the o-ring (3) if damaged or worn. Lubricate the o-ring with No. 2 grease. Bend it into a
kidney shape, then carefully push it into the groove
to avoid damaging it.
12. Lubricate the filter bowl (7) threads and screw it
firmly into the housing (9).
NOTE: Be sure the bottom drain plug or drain valve is
closed before starting the pump.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 5.
1. Relieve the pressure.
2. Carefully remove the drain plug (1) from the bottom of the filter bowl (7) to drain the fluid.
NOTES:
D Some models are supplied with a drain valve
(12). Refer to the parts list for your model.
D Drain plug not used with Model 241107.
3. Unscrew the bowl from the filter housing (9).
4. Pull the screen (5) straight out of the bowl. (See
Accessories for other available screens.)
5. Remove the compression spring (8) from the filter
bowl (7).
6. To remove the filter support (6), gently push in on
the filter support stud. Replace the filter support if
the ridges are worn.
7. Clean all parts thoroughly with a compatible solvent.
Model 214570, 236789: Apply PTFE tape to all nonswiveling pipe threads.
All other models: Apply anaerobic pipe sealant to all
non-swiveling pipe threads.
