Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation
point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these
symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific hazard
symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.
WARNING
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• 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 from distributor or retailer.
• Turn off all equipment and follow the Pressure Relief Procedure when equipment is not in use.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufac-
turer’s replacement parts only.
• Do not alter or modify equipment. Alterations or modifications may void agency approvals and create
safety hazards.
• Use equipment only for its intended purpose. Call your distributor for information.
• Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or flu-
ids containing such solvents.
• Comply with all applicable safety regulations.
MOVING PARTS HAZARD
Moving parts can pinch, cut 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 and disconnect all power sources.
SKIN INJECTION HAZARD
High-pressure spray is able to inject toxins into the body and cause serious bodily injury. In the event that
injection occurs, get immediate surgical treatment.
• Do not aim the gun at, or spray any person or animal.
• Keep hands and other body parts away from the discharge. For example, do not try to stop leaks with
any part of the body.
• Always use the nozzle tip guard. Do not spray without nozzle tip guard in place.
• Do not leave the unit energized or under pressure while unattended. When the unit is not in use, turn
off the unit and follow the Pressure Relief Procedure for turning off the unit.
• Always engage the trigger lock when not spraying. Verify the trigger lock is functioning properly.

Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Engage trigger lock.
2. Turn ON/OFF switch to OFF.
3. Disengage trigger lock. Hold metal part of gun
against grounded metal pail and trigger gun into pail
to relieve pressure.
4. Engage the trigger lock.
5. 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.
6. 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.

Tools & Materials Needed
•Vise
• 12 in. adjustable, open-end wrench (2)
• Hammer (20 oz maximum)
• Small screwdriver
• Pick or long small screwdriver
• Throat Seal Liquid
• Medium strength threadlocker
•Grease
• SAE 30W oil
Cleaning and Inspecting Parts
Clean and inspect parts. Pay particular attention to the
ball seats in the intake valve and piston, which must
have no nicks or wear, and to the inside of the cylinder
and the outside of the piston rod, which must not be
worn or scratched. Replace worn or damaged parts.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief Pro-
cedure when you stop spraying and before cleaning,
checking, or servicing the equipment.

Disassemble
1. Remove seal (201), packing nut (202) and o-ring
(228).
2. Unscrew intake valve from cylinder.
3. Disassemble intake valve. Clean and inspect o-ring
(227). NOTE: A pick may be required to remove
o-ring.
4. Tap piston rod out of cylinder with a hammer or flip
over and tap piston rod out against a bench.

5. Unscrew piston valve from piston rod. Clean and
inspect parts. The piston has a special thread lock-
ing/sealing patch. Do not remove the patch. The
patch allows four disassembly/assembly procedures
before it is necessary to apply medium strength
threadlocker to the threads.
6. Remove packings and glands from piston rod.
7. Remove throat packings and glands from cylinder.
Discard throat packings and glands.
Assemble
1. Soak all leather packings in SAE 30W oil for 1 hour
minimum prior to assembly. Stack male gland (219)
on piston rod. Alternately stack UHMWPE (208) and
leather (218) packings (note orientation) on piston
rod. Install female gland (209). Install piston wiper
(217) (note orientation) on piston valve, threads are
good for four repackings. Use medium strength
threadlocker on piston valve threads after four
repackings.

2. Install ball (206) in piston rod. If threadlocker is
applied to piston valve threads, make sure that none
gets on ball.
3. Tighten piston valve to piston rod. torque piston
valve to 27 ± 3 ft-lb. (37 ± 4.1 N•m).
4. Soak all leather packings in SAE 30W oil for one
hour minimum prior to assembly. Place male gland
(204) in cylinder. Alternately stack UHMWPE (203)
and leather packings (223) (note orientation). Place
female gland (224) on top of cylinder seat packings.
5. O-ring replaces clip ring on older models. Install
o-ring (228) onto packing nut. Loosely install pack-
ing nut into cylinder.

6. Grease piston packings.
7. Grease top inch or two of piston rod that will go
through the cylinder throat packings.
8. Slide piston rod assembly into bottom of cylinder.
Replace o-ring (207) if desired.
9. Reassemble intake valve with new o-ring (227),
seat (212) and ball (214). Seat may be flipped over
and used on other side. Clean seat thoroughly.
10. Install intake valve on cylinder. If a wrench is used
torque to 60 ± 5 ft-lb (81 ± 7 N•m).
NOTICE
Do not slide piston assembly into top of cylinder as this
may damage piston packing.

11. Torque packing nut (202) to 75 ± 5 in.-lb (8.5 ± .5
N•m).
12. Remove throat seal (201) when pump packings
begin to leak after extended use. Then tighten pack-
ing nut down until leakage stops or lessens. This
allows approximately 100 gallons of additional oper-
ation before a repacking is required.
