Warnings
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 symbol refers to procedure-specific risk. 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.
• 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.
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 manufacturer’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.
312473B 3
Warnings
WARNING
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
PRESSURIZED ALUMINUM PARTS HAZARD
Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids
containing such solvents in pressurized aluminum equipment. Such use can cause serious chemical
reaction and equipment rupture, and result in death, serious injury, and property damage.

Installation
Installation
Grounding
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
Pump: use the ground wire and clamp (supplied). See
F
IG. 1. Use the ground screw (GS) and lock washer
(LW) to attach the ground wire (N) at the rear of the air
motor. Tighten the screw securely. Connect the other
end of the ground wire to a true earth ground (P).
N
P
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray
gun/dispense valve firmly to the side of a grounded
metal pail, then trigger the gun/valve.
Flush Before Using Equipment
The equipment was tested with water. To avoid contaminating your fluid with water, flush the equipment with a
compatible solvent before using the equipment. See
your pump manual. See Related Manuals, page 2.
GS, LW
FIG. 1. Ground Wire
Air and fluid hoses: use only electrically conductive
hoses.
Air compressor: follow manufacturer’s recommendations.
Spray gun / Dispense valve: ground through connec-
tion to a properly grounded air or fluid hose and pump.
Air hose is conductive and used to ground gun. If adding
lengths to hose be sure to use conductive hoses.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts
grounding continuity.

Controls and Components
Controls and Components
Trapped air can cause the pump to cycle unexpectedly,
which could result in serious injury from splashing or
moving parts.
Sprayer Controls
• Pump air pressure regulator (C): a locking regula-
tor to adjust air pressure to the motor and fluid outlet
pressure of pump. View the air pressure gauge to
read air pressure.
• Gun air pressure regulator (D): a locking regulator
to adjust air pressure to the gun. View the air pressure gauge to read air pressure.
• Fluid pressure regulator (E): used to adjust the
fluid pressure to the spray gun.
• Bleed-type master air valve (L): required in your
system to relieve air trapped between it and the air
motor when the valve is closed.
Pump Operation and Repair
Follow the Pressure Relief Procedure in your pump
manual before cleaning or repairing your equipment.
For complete instructions and warnings see your respective pump manual. See
Related Manuals
, page 2.
Required Components
• Main Air Supply (J): connects air supply from air
compressor to pump.
(not included)
Recommended Components
• Air line filter (F): removes harmful contaminants
from entering the air control module and air motor.
• Air line moisture drain valve (M): installed at the
bottom of each air line drop, to drain moisture.
