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.
• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment
until you identify and correct the problem.
• Keep a working fire extinguisher in the work area.
Static charge may build up on plastic parts during cleaning and could discharge and ignite flammable
materials and gases. To help prevent fire and explosion:
• Clean plastic parts in a well ventilated area.
• Do not clean with a dry cloth.
• Do not operate electrostatic guns in equipment work area.

Warnings
6313435ZAA
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 in this manual 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.
• 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.
PRESSURIZED EQUIPMENT HAZARD
Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and
cause serious injury.
• Follow Pressure Relief Procedure in this manual, when you stop spraying 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.
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 prop-
erty 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
supplier for compatibility.
PLASTIC PARTS CLEANING SOLVENT HAZARD
Use only compatible water-based solvents to clean plastic structural or pressure-containing parts. Many
solvents can degrade plastic parts and cause them to fail, which could cause serious injury or property
damage. See Technical Data in this and all other equipment instruction manuals. Read fluid and solvent
manufacturer’s warnings.
WARNING

Warnings
313435ZAA 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 MSDS’s to know the specific hazards of the fluids you are using.
• Route exhaust away from work area. If diaphragm ruptures, fluid may be exhausted with 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
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:
• Clothing and respirator as recommended by the fluid and solvent manufacturer
• Protective eyewear, gloves, and hearing protection.

Repair
Pressure Relief Procedure
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. For motors with Pulse Count or DataTrak:
Remove screw to disconnect the reed switch
assembly from the air valve.
4. For motors with DataTrak: Remove two screws
and the solenoid bracket. Pull the solenoid out of
the air valve.
5. Remove screws (109, metal pumps) or nuts (112,
plastic pumps). Remove the air valve and gasket
(108).
6. 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 7.
7. Align the new air valve gasket (108) on the center
housing, then attach the air valve. See Torque
Instructions, page 18.
SPECIAL CONDITIONS FOR SAFE USE
Equipment must comply with the following
conditions to avoid a hazardous condition
which can cause fire or explosion.
• All label and marking material must be
cleaned with a damp cloth (or equiva-
lent).
• The electronic monitoring system is
required to be grounded. See Grounding
instructions in your pump operation man-
ual.
Trapped air can cause the pump to cycle unexpect-
edly, which could result in serious injury from splash-
ing.
