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).

• Sprayer generates sparks. When flammable liquid is used in or near the sprayer or for flushing or

cleaning, keep sprayer at least 20 feet (6 m) away from explosive vapors.

• Keep work area free of debris, including solvent, rags and gasoline.

• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.

• Ground equipment and conductive objects in work area. Read Grounding instructions.

• 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.

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.

BURN HAZARD

Equipment surfaces can become very hot during operation. To avoid severe burns, do not touch hot

equipment. Wait until equipment has cooled completely.

MOVING PARTS HAZARD

Moving parts can pinch 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 in this manual. Disconnect power or air supply.

Warning

311990J 3

Grounding and Electric

Requirements

The sprayer cord includes a grounding wire with an

appropriate grounding contact.

The sprayer requires:

100-130 Vac, 60 Hz, 11A, 1 phase, circuit with a

grounding receptacle.

Never use an outlet that is not grounded or an

adapter.

Do not use the sprayer if the electrical cord has a dam-

aged ground contact. Only use an extension cord with

an undamaged ground contact.

Recommended extension cords:

110-120V: 3-wire, 12 AWG (2.5 mm2) minimum, 300 ft

(90 m) maximum length.

NOTE: Smaller gauge or longer extension cords may

reduce sprayer performance.

Spray gun: ground through connection to a properly

grounded fluid hose and pump.

Fluid supply container: follow local code.

Solvent and Oil-based fluids: follow local code. Use

only conductive metal pails placed on a grounded sur-

face such as concrete. Do not place the pail on a non-

conductive surface such as paper or cardboard, which

interrupts grounding continuity.

Grounding the metal pail: connect a ground wire to the

pail by clamping one end to pail and other end to ground

such as a water pipe.

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.

Pressure Relief Procedure

6311990J

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever

you see this symbol.

1. Turn OFF power and turn pressure control to lowest

pressure setting.

2. Hold gun against side of grounded metal flushing

pail. Trigger gun to relieve pressure.

3. Turn prime valve down.

If you suspect the spray tip or hose is clogged or that

pressure has not been fully relieved after following the

steps above, VERY SLOWLY loosen tip guard retaining

nut or hose end coupling to relieve pressure gradually,

then loosen completely. Clear hose or tip obstruction.

4. Engage trigger safety lock on gun if unit is being

shut down or left unattended.

This equipment stays pressurized until pressure is

manually relieved. To help prevent serious injury

from pressurized fluid, such as skin injection,

splashing fluid and moving parts, follow the Pressure

Relief Procedure when you stop spraying and before

cleaning, checking, or servicing the equipment.

General Repair Information

311990J 7

General Repair Information

• Keep all screws, nuts, washers, gaskets, and elec-

trical fittings removed during repair procedures.

These parts usually are not provided with replace-

ment kits.

• Test repairs after problems are corrected.

• If sprayer does not operate properly, review repair

procedure to verify you did it correctly. See Trou-

bleshooting, page 8.

• Overspray may build up in the air passages.

Remove any overspray and residue from air pas-

sages and openings in the enclosures whenever

you service sprayer.

• Do not operate the sprayer without the motor shroud

in place. Replace if damaged. Motor shroud directs

cooling air around motor to prevent overheating and

insulates the control board from accidental electric

shock.

Flammable materials spilled on hot, bare, motor

could cause fire or explosion. To reduce risk of

burns, fire or explosion, do not operate sprayer with

cover removed.

To reduce risk of serious injury, including electric

shock:

• Do not touch moving or electric parts with fingers

or tools while testing repair.

• Unplug sprayer when power is not required for

testing.

• Install all covers, gaskets, screws and washers

before you operate sprayer.

CAUTION

• Do not run sprayer dry for more than 30 seconds.

Doing so could damage pump packings.

• Protect the internal drive parts of this sprayer from

water. Openings in the cover allow for air cooling of

the mechanical parts and electronics inside. If

water gets in these openings, the sprayer could

malfunction or be permanently damaged.

• Prevent pump corrosion and damage from freez-

ing. Never leave water or water-base paint in

sprayer when its not in use in cold weather. Freez-

ing fluids can seriously damage sprayer. Store

sprayer with Pump Armor to protect sprayer during

storage.
