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.

WARNINGWARNINGWARNING

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

manufacturer’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

fluids 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. Unplug power cord.

4. Disengage trigger lock. Hold metal part of gun

against grounded metal pail and trigger gun into pail

to relieve pressure.

5. Engage the trigger lock.

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.

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.

Tools Needed

•Vise

• 12 in. adjustable, open-end wrench (2)

• Hammer (20 oz maximum)

• Small screwdriver

• Throat Seal Liquid

• Pick or long small screwdriver

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 sleeve

and the outside of the piston rod, which must not be

worn or scratched. Replace worn or damaged parts.

NOTE:

Remove and clean sleeve when repacking pump.

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

Procedure when you stop spraying and before

cleaning, checking, or servicing the equipment.

Repair When Pump is Separated

From Sprayer

Disassembling the Pump

1. Remove 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.

NOTE: Spring (233) only used on 16Y601, 16X423, and

16X425

4. Tap piston rod out of cylinder with a hammer or flip

over and tap piston rod out against a bench.

NOTE: Sleeve may come out of cylinder with piston rod.

5. Remove piston rod from sleeve, or remove sleeve

from cylinder. Mark IV and Mark VII models:

Remove sleeve spacer (230) from sleeve.

COMPONENT RUPTURE HAZARD

To reduce the risk of serious injury from pressurized

fluid, do not clean or wipe the piston valve threads.

Cleaning the piston valve threads could destroy the

special sealing patch and cause the piston valve to

come loose during operation.

6. 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 thread sealant to the

threads.

7. Remove packings and glands from piston rod.

8. Remove throat packings and glands from cylinder.

Discard throat packings and glands.

Assembling the Pump

1. Soak all leather packings in SAE 30W oil for 1 hour

minimum prior to assembly. Stack male gland (204)

on piston rod. Alternately stack UHMWPE (208) and

leather (218) packings (note orientation) on piston

rod. Install female gland (217). Install piston wiper

(216) (note orientation) and backup washer (229) on

piston valve, threads are good for four repackings.

Use thread sealant on piston valve threads after

four repackings.

2. Install ball (206) in piston rod. If thread sealant is

applied to piston valve threads, make sure that none

gets on ball.

3. Tighten piston valve to piston rod as specified:

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) in top of cylinder seat packings.

5. Install seal (201) into packing nut (202). Install

o-ring (228) onto packing nut. Loosely install pack-

ing nut into cylinder.

6. Grease piston packings.

7. Slide piston assembly into bottom of sleeve.

8. Grease top inch or two of piston rod that will go

through the cylinder throat packings.
