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 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
ELECTRIC SHOCK HAZARD
This equipment must be grounded. Improper grounding, setup, or usage of the system can cause
electric shock.
• Turn off and disconnect power cord before servicing equipment.
• Connect only to grounded electrical outlets.
• Use only 3-wire extension cords.
• Ensure ground prongs are intact on power and extension cords.
• Do not expose to rain. Store indoors.
• Wait five minutes after disconnecting power cord before servicing.
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. Paint or
solvent flowing through the equipment can cause static sparking. 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 sparking).
• Ground all equipment in the work area. See Grounding instructions.
• Never spray or flush solvent at high pressure.
• 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.
• Use only grounded hoses.
• Hold gun firmly to side of grounded pail when triggering into pail. Do not use pail liners unless they
are anti-static 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.
BURN HAZARD
Equipment surfaces and fluid that is heated can become very hot during operation. To avoid severe
burns:
• Do not touch hot fluid or equipment.

Warnings

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.
• Equipment can start without warning. Before checking, moving, or servicing equipment, follow the
Pressure Relief Procedure and disconnect all power sources.
SKIN INJECTION HAZARD
High-pressure fluid from gun, 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 spray without tip guard and trigger guard installed.
• Engage trigger lock when not spraying.
• Do not point gun at anyone or at any part of the body.
• Do not put your hand over the spray tip.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Follow the Pressure Relief Procedure when you stop spraying 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.
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 Safety Data Sheets (SDSs) 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.
WARNING

Warnings
3A8478A 5
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. 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.
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 Safety Data Sheets (SDSs) 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
manufacturer’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.

Installation
Power Requirements
See Table 1 for power source requirements. The
system requires a dedicated circuit protected with a
circuit breaker.
Connect Power
1. Cut power cord wires to the following lengths:
- Ground wire - 6.5 inches (16.5 cm)
- Power wires - 3.0 inches (7.6 cm)
- Add ferrules as necessary. See FIG. 1.
2. Bring cord to unit and remove four screws to
separate junction box cover (Z) with power switch
(S) from junction box (Y). See FIG. 1.
3. With junction box cover (Z) and power switch (S)
detached from machine, wires inside junction will
appear as below.
NOTE: The two fan harness wires will be installed in
disconnect block (J) in both 1L1 and 3L2 terminals.
4. Insert power cord (from step 1) through cord grip
(X1) and into junction box (Y). Attach the power
cord ground wire to the lower ground terminal inside
junction box (Y).
5. Power wires should be installed into 2T1 and 4T2
terminals. See Wiring Diagrams on page 27.
NOTE: The upper ground screw is used by the fan wire
harness and should not be used for both connections.
6. Place fan wires and other power wires into open
area on either side of disconnect block (J) as space
permits. Reinstall junction box cover (Z).
Improper wiring may cause electric shock or other
serious injury. All electrical wiring must be done by a
qualified electrician and comply with all local codes
and regulations.

Grounding
Driver: The driver is grounded through the power cord.
See Connect Power, page 7.
Install Vented Oil Cap Before
Using Equipment
The driver gear-box is pre-filled with oil. The temporary
unvented cap (PX) prevents oil leaks during shipment.
This temporary cap must be replaced with the vented oil
cap (P), supplied with the equipment, before use.

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.
