Warnings
WARNING
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, 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.
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in the work area can ignite or explode. To help prevent
fire and explosion:
• Use equipment only in a well-ventilated area.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop
cloths (potential static arc).
• Keep the 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 the gun firmly to the side of a grounded pail when triggering into a pail.
• If there is static sparking or you feel a shock, stop operation immediately. Do not use the 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
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 the equipment work area.
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 the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or ser-
vicing the equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
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 the Safety Data Sheet (SDS) 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.

Warnings
WARNING
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, 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.
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 Specifications in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Specifications
in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information
about your material, request a Safety Data Sheet (SDS) from your 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 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.
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.

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 a ground wire and clamp. See FIG. 1.
Loosen the locknut (W) of the grounding lug (Z). Insert
one end of the wire (Y) in the ground lug and tighten the
locknut securely. Connect the ground clamp to a true
earth ground. Order Part No. 237569, Ground Wire and
Clamp.
Air and fluid hoses: use only electrically conductive
hoses with a maximum of 500 ft. (150 m) combined
hose length to ensure grounding continuity. Check the
electrical resistance of hoses. If total resistance to
ground exceeds 25 megohms, replace hose immediately.
Hydraulic power supply: follow manufacturer’s recommendations.
Surge tank: use a ground wire and clamp.
Dispense valve: ground through a connection to a
properly grounded fluid hose and pump.
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.
F
IG. 1 Ground Wire
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray gun
firmly to the side of a grounded metal pail, then trigger
the gun.

Installation
Stand Mount
Mount the pump in the accessory pump stand (B). Use
Part No. 218742 Stand for 3000 and 4000cc Pumps
(see F
IG. 2, page 9).
See Mounting Stand Hole Layout on page 18. Secure
the stand to the floor with M19 (5/8 in.) bolts which
engage at least 152 mm (6 in.) into the concrete floor to
prevent the pump from tipping.
Wall Mount
1. Ensure the wall is strong enough to support the
weight of the pump assembly and accessories, fluid,
hoses, and stress caused during pump operation.
2. Ensure that the mounting location has sufficient
clearance for easy operator access.
3. Position the wall bracket at a convenient height,
ensuring that there is sufficient clearance for the
fluid suction line and for servicing the lower.
4. Drill four 7/16 in. (11 mm) holes using the bracket as
a template. Use any of the three mounting hole
groupings in the bracket. See 255143 Wall Mount
Bracket, page 19.
Plumbing
Install a fluid shutoff valve (D) between the mix tank (A)
and the pump.
When using a stainless steel pump, use stainless steel
plumbing to maintain a corrosion-resistant system.
Flush Before Using Equipment
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid contaminating your fluid with oil, flush the equipment with a
compatible solvent before using the equipment. See
Flushing, page 11.
5. Bolt the bracket securely to the wall using bolts and
washers designed to hold in the wall’s construction.
6. Attach the pump assembly to the mounting bracket.
7. Connect air and fluid hoses.
