Warnings  
WARNING  
EQUIPMENT MISUSE HAZARD  
Misuse can cause death or serious injury.  
Do not operate the unit when fatigued or under the influence of drugs or alcohol.  
Do not exceed the maximum working pressure or temperature rating of the lowest rated system  
component. See Technical Data in all equipment manuals.  
Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all  
equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information  
about your material, request MSDS forms from distributor or retailer.  
Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manu-  
facturer’s replacement parts only.  
Do not alter or modify equipment.  
Use equipment only for its intended purpose. Call your distributor for information.  
Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.  
Do not kink or over bend hoses or use hoses to pull equipment.  
Keep children and animals away from work area.  
Comply with all applicable safety regulations.  
MOVING PARTS HAZARD  
Moving parts can pinch or amputate fingers and other body parts.  
Keep clear of moving parts.  
Do not operate equipment with protective guards or covers removed.  
Pressurized equipment can start without warning. Before checking, moving, or servicing equipment,  
follow the Pressure Relief Procedure in this manual. Disconnect power or air supply.  
TOXIC FLUID OR FUMES HAZARD  
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or  
swallowed.  
Read MSDS’s to know the specific hazards of the fluids you are using.  
Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.  
Always wear impervious gloves when spraying or cleaning equipment.  
PERSONAL PROTECTIVE EQUIPMENT  
You must wear appropriate protective equipment when operating, servicing, or when in the operating  
area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic  
fumes, burns, and hearing loss. This equipment includes but is not limited to:  
Protective eyewear  
Clothing and respirator as recommended by the fluid and solvent manufacturer  
Gloves  
Hearing protection  
SKIN INJECTION HAZARD  
High-pressure fluid from dispense valve, hose leaks, or ruptured components will pierce skin. This may  
look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical  
treatment.  
Do not point dispense valve at anyone or at any part of the body.  
Do not put your hand over the end of the dispense nozzle.  
Do not stop or deflect leaks with your hand, body, glove, or rag.  
Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,  
checking, or servicing equipment.

Operation  
Operation  
6. Open all fluid drain valves in the system, having a  
waste container ready to catch drainage. Leave  
drain valve(s) open until you are ready to spray  
again.  
Pressure Relief Procedure  
7. If you suspect the spray tip or hose is clogged or  
that pressure has not been fully relieved after follow-  
ing the steps above, VERY SLOWLY loosen tip  
guard retaining nut or hose end coupling to relieve  
pressure gradually, then loosen completely. Clear  
hose or tip obstruction.  
1. Engage trigger lock.  
2. Air-Powered Pumps only: Close the bleed-type  
master air valve.  
Hydraulic-Powered Pumps only: Close the hydraulic  
supply line valve first, then the return line valve.  
CAUTION  
Hydraulic-Powered Pumps only: When shutting down  
the hydraulic system, always shut off the hydraulic  
supply line shutoff valve first, and then the return line  
shutoff valve to prevent overpressurizing the motor or  
its seals. When starting the hydraulic system, open  
the return line shutoff valve first.  
3. Disengage the trigger lock.  
4. Hold a metal part of the gun firmly to a grounded  
metal pail. Trigger the gun to relieve pressure.  
5. Engage the trigger lock.

Piston  
To service the pump assembly, see manual  
311833.  
1. Remove the intake valve as explained above.  
2. Pull the cylinder (24) down, off the piston assembly.  
To service the air motor, see manual 311238.  
3. Unscrew the piston retainer screws (12). Remove  
the piston parts from the displacement rod (22).  
Disconnect the Lower  
4. Clean all parts thoroughly, and inspect them for  
wear or damage. Replace parts as needed.  
5. Place the gasket (49) and ball (3) on the piston  
retainer (27). Install these parts in the displacement  
rod.  
1. Flush the pump, if possible. Relieve the pressure,  
see Pressure Relief Procedure on page 4.  
2. Disconnect the hoses from the lower and plug the  
ends to prevent fluid contamination.  
The piston retainer (27) must not obstruct the ports  
in the displacement rod (22).  
3. Remove the pump from its mounting and place it in  
a vise.  
6. Install one cup packing (17) on the displacement rod  
(22). Be sure the lips of the packing face up.  
4. Disconnect the lower from the motor as explained in  
your separate pump manual.  
7. Install the packing spacer (16). Position one cup  
packing (17) on the displacement rod so the lips of  
the packing face down.  
Lower Repair  
8. Install the piston guide (21). Install the four screws  
(12) through the piston assembly and screw them  
into the displacement rod (22). Torque the screws  
evenly to 30-40 ft-lb (41-54 N•m), using a  
criss-cross tightening pattern.  
Intake Valve  
1. Remove the hex nuts (1) and washers (30) from the  
tie rods (18). Unscrew the tie rods from the intake  
valve. Remove the intake valve from the pump.  
9. If no further service is need, go to Throat Packings.  
If no further service is needed, slide the cylinder  
(24) and gaskets (49*) over the piston assembly.  
Install the intake valve. Torque the nuts (1) evenly to  
50-60 ft-lb (68-81 N•m).  
2. Disassemble the intake valve. Take note of which  
set of holes the ball stop pin (14) is in.  
3. Clean all parts thoroughly, and inspect them for  
wear or damage. Replace parts as needed.  
Throat Packings  
4. Reassemble the valve. Place the ball stop pin (14) in  
the same holes from which it was removed. If you  
want to change the fluid flow through the pump,  
place the pin in a different set of holes. Refer to  
Check Valve Adjustment, page 6.  
1. Remove the intake valve and the cylinder (24) as  
explained in the previous sections.  
2. Remove the wet cup (45).  
3. Pull the displacement rod (22) out of the bottom of  
the outlet housing (46).  
5. If no further service is needed, reinstall the intake  
valve on the pump. Torque the hex nuts (1) evenly to  
50-60 ft-lb (68-81 N•m), using a criss-cross tighten-  
ing pattern.  
4. Remove the throat packings and glands from the  
outlet housing (46).  
5. Clean all parts thoroughly, and inspect them for  
wear or damage. Replace parts as needed.

Repair  
Reconnect the Lower  
Always replace the male gland (40) and the bearing  
(47) when the throat packings are replaced.  
1. Reinstall the displacement pump on the motor as  
explained in your pump manual.  
6. Install the throat packings into the outlet housing  
(46) one at a time in the following order, with the lips  
of the v-packings facing down:  
2. Reconnect the ground wire to the motor.  
Check Valve Adjustment  
The fluid piston and intake valves are factory-set for  
high-volume pumping of heavy, spray-viscosity fluids.  
The male gland (40*), two UHMWPE v-packings  
(41*), one leather v-packing (42*), one UHMWPE  
v-packing, one leather v-packing (42*), one UHM-  
WPE v-packing, and the bearing (41). Loosely  
install the wet cup (45).  
For lighter fluids or lower volume requirements, or to  
reduce surging at the stroke change-over, decrease the  
travel of the balls (3 and 4). Move the pins (2) to a lower  
set of holes. See Parts, page 8 and refer to disassembly  
procedure above.  
7. Push the displacement rod (22) up into the outlet  
housing (46) until it protrudes from the wet cup (45).  
Continue reassembling the pump in the reverse  
order of disassembly. Tighten the wet cup just tight  
enough to prevent leakage.  
If the ball travel is too short for the fluid being  
pumped, the fluid flow will be restricted.  
For heavier fluids or to increase the flow, increase the  
travel of the balls (3 and 4). See Parts, page 8 and refer  
to disassembly procedure above.
