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.
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.
• Keep work area free of debris, including solvent, rags, and gasoline.
• Ground equipment in the work area. See 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.
Equipment Misuse Hazard
Equipment misuse can cause death or serious injury.
• Do not exceed maximum working pressure or temperature rating of lowest rated system compo-
nent. 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.
• Check equipment daily. Repair or replace worn or damaged parts immediately.
• Do not alter or modify this equipment.

• Use only grounded electrical outlets.
• Use only 3-wire extension cords.
• Ensure ground prongs are intact on sprayer and extension cords.

Warnings
4310645L
WARNING
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 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.
• Do not spray without tip guard and trigger guard installed.
• Engage trigger lock when not spraying.
• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,
checking, or servicing equipment.
Cleaning Solvent Hazard with Plastic Parts
Use only compatible water-based solvents to clean plastic structural or pressure-containing parts. Many
solvents can degrade plastic parts to the point where they could fail. Such failure could cause serious
injury or property damage. See Technical Data on page 34 of this instruction manual and in all other
equipment manuals. Read fluid and solvent manufacturer’s warnings.
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.

Wear appropriate protective equipment when operating, servicing or when in the operating area of this
equipment to help protect yourself from serious injury, including eye injury, inhalation of toxic fumes,
burns and hearing loss. This equipment includes, but is not limited to:
• protective eye wear

(A) OFF.
2. Turn fluid flow regulator
(K) all the way down to
reduce pressure.
3. Open gun air valve (aa).
4. Trigger gun, spray-
ing material back

Grounding and Electric
Requirements
The sprayer must be grounded. Grounding reduces the
risk of electrical shock by providing an escape wire for
the electrical current.
• The sprayer cord includes a
grounding wire with an appro-
priate grounding prong.
• The plug must be plugged
into an outlet that is properly
installed and grounded in
accordance with all local
codes and ordinances.
• Do not modify plug! If it will
not fit in outlet, have
grounded outlet installed by a
qualified electrician.
• Sprayer model electric
requirements are provided on
page 2.
Extension Cords
• Only use an extension cord with
an undamaged 3-prong plug.
• For up to 100 ft (30.48 m) cord,
use 3-wire, 12 AWG (2.5 mm2)
minimum.

Auxiliary Air Compressor
• Use Auxiliary Air Hookup Kit 287328 when addi-
tional atomization air is necessary.
Generators
7500 W (7.5 KW) minimum.
Tips for Using Generators
• Before running sprayer, make sure it is at room tem-
perature. This will reduce startup current.
• Run generator at full throttle.
Hose Lengths
• The system comes with a twin line hose set consist-
ing of a 1 in. ID x 25 ft (25 mm x 7.6 m) material
hose and a 3/8 in. ID air hose. Additional hose sec-
tions can be added. Total final length of hose used
should not exceed 100 feet in length.
NOTICE
Attaching auxiliary air to sprayer without using the
Auxiliary Air Hookup Kit will damage sprayer.
NOTICE
Sprayer air hose fitting can get hot! Allow sprayer to
cool down 5 minutes before removing air hose.
