Safety Precautions
This manual contains information that must be read and
understood before using the equipment. When you come to an
area that has one of the following symbols, pay particular
attention and make certain to heed the safeguard.
This symbol indicates a potential hazard which may cause
serious injury or loss of life. Important safety information
will follow.
This symbol indicates a potential hazard to you or to the
equipment. Important information that tells how to prevent
damage to the equipment or how to avoid causes of minor
injuries will follow.
HAZARD: Injection injury — A high pressure fluid stream
produced by this equipment can pierce the skin
and underlying tissues, leading to serious injury
and possible amputation. See a physician
immediately.
DO NOT TREAT AN INJECTION INJURY AS A SIMPLE CUT!
Injection can lead to amputation. See a physician immediately.
The maximum operating range of the gun is 3900 PSI / 27
MPa fluid pressure.
PREVENTION:
• NEVER aim the gun at any part of the body.
• NEVER allow any part of the body to touch the fluid stream.
DO NOT allow body to touch a leak in the fluid hose.
•NEVER put hand in front of the gun. Gloves will not
provide protection against an injection injury.
• ALWAYS lock the gun trigger, shut pump off, and release all
pressure before servicing, cleaning tip or guard, changing
tip, or leaving unattended. Pressure will not be released by
turning off the motor. The PRIME/SPRAY valve or pressure
bleed valve must be turned to their appropriate positions to
relieve system pressure. Refer to the PRESSURE RELIEF
PROCEDURE described in the sprayer’s Owner’s Manual.
• ALWAYS keep tip guard in place while spraying. The tip guard
provides some protection but is mainly a warning device.
• ALWAYS remove the spray tip before flushing or cleaning
the system.
• Paint hose can develop leaks from wear, kinking and
abuse. A leak can inject material into the skin. Inspect the
hose before each use.
• NEVER use a spray gun without a working trigger lock and
trigger guard in place.
• All accessories must be rated at or above the maximum
operating pressure range of the airless sprayer. This
includes spray tips, guns, extensions, and hose.
NOTE TO PHYSICIAN:
Injection into the skin is a traumatic injury. It is
important to treat the injury as soon as possible. DO
NOT delay treatment to research toxicity. Toxicity is a
concern with some coatings injected directly into the
blood stream. Consultation with a plastic surgeon or
reconstructive hand surgeon may be advisable.
WARNING
NOTE: Notes give important information which should
be given special attention.
CAUTION
WARNING
HAZARD: EXPLOSION AND FIRE - Solvent and paint fumes
can explode or ignite. Severe injury and/or
property damage can occur.
PREVENTION:
• Provide extensive exhaust and fresh air introduction to keep
the air within the spray area free from accumulation of
flammable vapors.
• Avoid all ignition sources such as static electricity sparks,
electrical appliances, flames, pilot lights, hot objects, and
sparks from connecting and disconnecting power cords or
working light switches.
• Do not smoke in spray area.
• Fire extinguisher must be present and in good working order.
• Place pump at least 25 feet (7.6 m) from the spray object in
a well ventilated area (add more hose if necessary).
Flammable vapors are often heavier than air. Floor area
must be extremely well ventilated. The pump contains
arcing parts that emit sparks and can ignite vapors.
• The equipment and objects in and around the spray area
must be properly grounded to prevent static sparks.
• Use only conductive or grounded high-pressure fluid hose.
Gun must be grounded through hose connections.
• Power cord must be connected to a grounded circuit.
• Always flush unit into separate metal container, at low pump
pressure, with spray tip removed. Hold gun firmly against
side of container to ground container and prevent static
sparks.
• Follow material and solvent manufacturer's warnings and
instructions.
• Use extreme caution when using materials with a flashpoint
below 70° F (21° C). Flashpoint is the temperature at which
a fluid can produce enough vapors to ignite.
• Plastic can cause static sparks. Never hang plastic to
enclose spray area. Do not use plastic drop cloths when
spraying flammable materials.
• Use lowest possible pressure to flush equipment.
GAS ENGINE (WHERE APPLICABLE)
Always place pump outside of structure in fresh air. Keep all
solvents away from engine exhaust. Never fill fuel tank with a
running or hot engine. Hot surface can ignite spilled fuel.
Always attach ground wire from pump to a grounded object.
Refer to engine owner’s manual for complete safety information.
HAZARD: EXPLOSION HAZARD DUE TO INCOMPATIBLE
MATERIALS - Will cause severe injury or property
damage. Some pumps and accessories contain
aluminum and cannot be used with halogenated
hydrocarbon solvents. Follow the prevention
section if your pump or accessories are not
compatible with halogenated hydrocarbon
solvents. The S-3 Airless Spray Gun is
compatible with halogenated hydrocarbon
solvents.
PREVENTION:
• Do not use materials containing bleach or chlorine.
• Do not use halogenated hydrocarbon solvents such as
bleach, mildewcide, methylene chloride and 1,1,1 -
trichloroethane. They are not compatible with aluminum.
• Contact your coating supplier about the compatibility of
material with aluminum.

Identifying Tip Sizes
To identify tip sizes, use the following formula. A “517” tip size
will be used in this example.
The first digit multiplied by two represents the size of the spray
pattern when spraying 12” away from the work surface:
5 x 2 = 10” spray pattern
The second two digits represent the diameter of the orifice on the
tip: 17 = .017” orifice
Cleanup
Maintaining a clean gun is important to ensure trouble-free
operation. Flush the gun after each use and store in a dry
location. Do not leave the gun or any of its parts in water or
solvents.
Special cleanup instructions for use with flammable
solvents:
• Always flush spray gun preferably outside and at least one
hose length from spray pump.
• If collecting flushed solvents in a one gallon metal container,
place it into an empty five gallon container, then flush
solvents.
• Area must be free of flammable vapors.
• Follow all cleanup instructions.
The sprayer, hose, and gun should be cleaned thoroughly
after daily use. Failure to do so permits material to cake,
seriously affecting the performance of the unit.
Always spray at minimum pressure with the
tip and tip guard removed when using
mineral spirits or any other solvent to clean
the sprayer, hose, or gun. Static electricity
buildup may result in a fire or explosion in
the presence of flammable vapors. Hold the
gun firmly against a metal container while flushing.
WARNING
CAUTION
WARNING
NOTE: Worn spray tips will adversely affect the spray
pattern and result in reduced production, poor
