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 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
FIRE AND EXPLOSION HAZARD
When flammable fluids are present in the work area, such as gasoline and windshield wiper fluid, be
aware that flammable fumes can ignite or explode. To help prevent fire and explosion:
• Use equipment only in well ventilated area.
• Eliminate all ignition sources, such as cigarettes and portable electric lamps.
• Keep work area free of debris, including rags and spilled or open containers of solvent and gasoline.
• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.
• Ground all equipment in the work area.
• Use only grounded hoses.
•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.
SKIN INJECTION HAZARD
High-pressure fluid from dispensing device, hose leaks, or ruptured components will pierce skin. This
may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical
treatment.
• Do not point dispensing device at anyone or at any part of the body.
• Do not put your hand over the fluid outlet.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Follow the Pressure Relief Procedure when you stop dispensing and before cleaning, checking, or
servicing equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses and couplings daily. Replace worn or damaged parts immediately.

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 com-
ponent. 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 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.
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.
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.
• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.
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 protective 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
WARNING

Installation

Installation
Grounding
Pump: Use a ground wire and clamp as shown in FIG. 1.
Air and fluid hoses: Use only electrically conductive
hoses.
Air compressor: Follow manufacturer’s recommenda-
tions.
Dispense valve: Ground through connection to a prop-
erly grounded fluid hose and pump.
Object being dispensed: 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 sur-
face, such as paper or cardboard, which interrupts
grounding continuity.
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.
To ground the pump: Remove the ground screw (Z)
and insert through the eye of the ring terminal at end of
ground wire (Y). Fasten the ground screw back onto the
pump and tighten securely. Connect the other end of the
ground wire to a true earth ground. See FIG. 1. To order
a ground and wire clamp, order Part No. 222011.
Mounting the Pump
• Select a convenient location for the equipment to
ensure easy operator access to the pump air con-
trols, sufficient room to change supply containers,
and a secure mounting platform.
• If you are mounting the pump directly on the supply
tank, position the pump so its intake valve is no
more than 1 inch (25 mm) from the bottom of the
container. Mount the pump to the cover or other suit-
able mounting device.
Typical Installation
Mount the pump to suit the type of installation planned.
Very heavy lubricant may require an inductor plate. See
page 17 for the mounting hole layout and dimensions.
Install the airline accessories in the approximate order
shown in FIG. 2. Install a bleed-type master air valve (B)
within easy reach of the pump, upstream from the air
regulator. Install an air filter (C) to remove harmful dirt
and moisture from your compressed air supply. For
automatic air motor lubrication, install an air line oiler (D)
close to the pump air inlet. Install an air regulator (E) to
control pump speed.
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.

Z
Mount the pump securely so that it cannot move
around during operation. Failure to do so could result
in personal injury or equipment damage.

Installation

Be sure the air hose is properly sized to deliver an ade-
quate supply of air to the motor. Refer to the Technical
Data on page 16.
Connect a dispensing hose to the 3/8 npt(f) pump outlet.
Install an appropriate gun or dispense valve to the hose.
Ground the pump as explained on page 4.

A bleed-type master air valve (B) is required to shut
off an relieve air pressure that may be trapped in the
air motor. Trapped air could cause the pump to cycle
unexpectedly and cause serious bodily injury,
including amputation.
