Warnings

Warnings

The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama-

tion point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. When

these symbols appear in the body of this manual, refer back to these Warnings. Additional, product-specific warnings

may be found throughout the body of this manual where applicable.

WARNING

FIRE AND EXPLOSION HAZARD

Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help

prevent fire and explosion:

• Use equipment only in well ventilated area.

• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop

cloths (potential static arc).

• Keep work area free of debris, including solvent, rags and gasoline.

• Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes

are present.

• Ground all equipment in the work area. See Grounding instructions.

• Use only grounded hoses.

• Hold gun firmly to side of grounded pail when triggering into pail. Do not use pail liners unless they

are antistatic or conductive.

•Stop operation immediately if static sparking occurs or you feel a shock.Do not use equipment

until you identify and correct the problem.

• Keep a working fire extinguisher in the work area.

• Route exhaust away from all ignition sources. If diaphragm ruptures, fluid may be exhausted with air.

Static charge may build up on plastic parts during cleaning and could discharge and ignite flammable

vapors. To help prevent fire and explosion:

• Clean plastic parts only in a well ventilated area.

• Do not clean with a dry cloth.

• Do not operate electrostatic guns in equipment work area.

PRESSURIZED EQUIPMENT HAZARD

Fluid from the equipment, leaks, or ruptured components can splash in the eyes or on skin and cause

serious injury.

• Follow the Pressure Relief Procedure when you stop spraying/dispensing and before cleaning,

checking, or servicing equipment.

• Tighten all fluid connections before operating the equipment.

• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.

Warnings

63A0411A

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 from distributor or retailer.

• Do not leave the work area while equipment is energized or under pressure.

• 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 manu-

facturer’s replacement parts only.

• Do not alter or modify equipment. Alterations or modifications may void agency approvals and create

safety hazards.

• Make sure all equipment is rated and approved for the environment in which you are using it.

• 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.

THERMAL EXPANSION HAZARD

Fluids subjected to heat in confined spaces, including hoses, can create a rapid rise in pressure due to

the thermal expansion. Over-pressurization can result in equipment rupture and serious injury.

• Open a valve to relieve the fluid expansion during heating.

• Replace hoses proactively at regular intervals based on your operating conditions.

PRESSURIZED ALUMINUM PARTS HAZARD

Use of fluids that are incompatible with aluminum in pressurized equipment can cause serious

chemical reaction and equipment rupture. Failure to follow this warning can result in death, serious

injury, or property damage.

• Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or

fluids containing such solvents.

• Many other fluids may contain chemicals that can react with aluminum. Contact your material sup-

plier for compatibility.

PLASTIC PARTS CLEANING SOLVENT HAZARD

Many solvents can degrade plastic parts and cause them to fail, which could cause serious injury or

property damage.

• Use only compatible water-based solvents to clean plastic structural or pressure-containing parts.

•SeeTechnical Data in this and all other equipment instruction manuals. Read fluid and solvent

manufacturer’s MSDSs and recommendations.

WARNING

Warnings

3A0411A 7

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 MSDSs to know the specific hazards of the fluids you are using.

• Route exhaust away from work area. If diaphragm ruptures, fluid may be exhausted into the air.

• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.

BURN HAZARD

Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid severe

burns:

• Do not touch hot fluid or equipment.

PERSONAL PROTECTIVE EQUIPMENT

Wear appropriate protective equipment when in the work area to help prevent serious injury, including

eye injury, hearing loss, inhalation of toxic fumes, and burns. This equipment includes but is not limited

to:

• Protective eyewear, and hearing protection.

• Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufacturer.

Pressure Relief Procedure

Follow the Pressure Relief Procedure when-

ever you see this symbol.

1. Shut off the air supply to the pump.

2. Open the dispensing valve, if used.

3. Open the fluid drain valve to relieve fluid pressure.

Have a container ready to catch the drainage.

Repair or Replace Air Valve

Replace Complete Air Valve

1. Stop the pump. Relieve the pressure. See Pressure

Relief Procedure in previous section.

2. Disconnect the air line to the motor.

3. Remove screws (104, metal pumps) or nuts (116,

plastic pumps). Remove the air valve and gasket

(113).

4. To repair the air valve, go to Disassemble the Air

Valve, step 1, in next section. To install a replace-

ment air valve, continue with step 5.

5. Align the new air valve gasket (113*) on the center

housing, then attach the air valve. See Torque

Instructions, page 20.

6. Reconnect the air line to the motor.

Replace Seals or Rebuild Air Valve

NOTE: Repair kits are available. See page 31 to order

the correct kit(s) for your pump. Air Valve Seal Kit parts

are marked with a †. Air Valve Repair Kit parts are

marked with a ◆. Air Valve End Cap Kit parts are

marked with a ✠.

Disassemble the Air Valve

1. Perform steps 1-3 under Replace Complete Air

Valve, page 10.

2. See FIG. 2. Use a Torx screwdriver (T8 for alumi-

num centers, T10 for plastic centers) to remove two

screws (209). Remove the valve plate (205),

cup assembly (212-214), spring (211), and detent

assembly (203).

3. Pull the cup (213) off of the base (212). Remove the

o-ring (214) from the cup.

4. See FIG. 2. Remove the retaining ring (210) from

each end of the air valve. Use the piston (202) to

push the end cap (207) out of one end. Remove the

u-cup seal (208). Pull the piston out the end and

remove the other u-cup seal (208). Remove the

other end cap (207) and the end cap o-rings (206).

5. Remove the detent cam (204) from the air valve

housing (201).

This equipment stays pressurized until pressure is

relieved manually. To help prevent serious injury from

pressurized fluid, such as splashing in the eyes or on

skin, follow the Pressure Relief Procedure whenever

you stop pumping and before you clean, check, or ser-

vice the equipment.
