Important Safety
Information
Read all safety information before operating the
equipment. Save these instructions
to PRIME to relieve the pressure. Refer to the
Pressure Relief Procedure (page 7) described in the
pump manual.
• ALWAYS keep the tip guard in place while spraying.
The tip guard provides some protection but is mainly
a warning device.
• ALWAYS remove the spray tip before ushing 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. Do not use hose
to lift or pull equipment.
• NEVER use a spray gun without a working trigger
lock and trigger guard in place.
• All accessories must be rated at or above 2800
PSI/193 BAR. 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.
HAZARD: HAZARDOUS VAPORS
Paints, solvents, insecticides, and other materials
can be harmful if inhaled or come in
contact with the body. Vapors can
cause severe nausea, fainting, or
poisoning.
PREVENTION:
• Use a respirator or mask if vapors can be inhaled.
Read all instructions supplied with the mask to be
sure it will provide the necessary protection.
• Wear protective eye wear.
• Wear protective clothing as required
by coating manufacturer.
HAZARD: EXPLOSION OR FIRE
Solvent and paint fumes can explode or
ignite. Property damage and/or severe
injury can occur.
PREVENTION:
• Provide extensive exhaust and fresh
air introduction to keep the air within
the spray area free from accumulation
of ammable vapors. Solvent and
paint fumes can explode or ignite.
• Do not spray in a conned area.
• Avoid all ignition sources such as static electric
sparks, open ames, pilot lights, electrical
appliances, and hot objects. Connecting or
disconnecting power cords or working light switches
can make sparks. Paint or solvent owing through
the equipment is able to result in static electricity.
• Do not smoke in spray area.
• Fire extinguisher must be present and in good
working order.
• Place paint pump in a well-ventilated area away
from the spray object. Flammable vapors are often
heavier than air. Floor area must be extremely well
ventilated.
• The equipment and objects in and around the spray
area must be properly grounded to prevent static
sparks.
• Keep area clean and free of paint or solvent
containers, rags and other ammable materials.
• Use only conductive or grounded high pressure
uid hose. Gun must be grounded through hose
connections.
• Power cord must be connected to a grounded
circuit.
• Always ush unit into a separate metal container,
at low pump pressure, with spray tip removed.
Hold gun rmly against side of container to ground
container and prevent static sparks.
• Follow the material and solvent manufacturer’s
warnings and instructions. Know the contents of the
paints and solvents being sprayed. Read all Material
Safety Data Sheets (MSDS) and container labels
provided with the paints and solvents. Follow the
paint and solvent manufacturer’s safety instructions.
Indicates a hazardous situation which,
if not avoided, could result in death or
serious injury.
HAZARD: Injection injury
A high pressure paint 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 2800
PSI/193 BAR uid pressure.
PREVENTION:
• NEVER aim the gun at any part of the body.
• Do not aim the gun at, or spray any person or
animal.
• NEVER allow any part of the body to touch the uid
stream. DO NOT allow body to touch a leak in the
uid hose.
• NEVER put your hand in front of the gun. Gloves
will not provide protection against an injection injury.
• ALWAYS lock the gun trigger, shut the pump off,
and release all pressure before servicing, cleaning
the tip or guard, changing tip, or leaving unattended.
Pressure will not be released by turning off the
motor. The PRIME/SPRAY knob must be turned
To reduce the risks of fire or explosion, electrical shock and the injury
to persons, read and understand all instructions included in this manual.
Be familiar with the controls and proper usage of the equipment.

• This product may be used only with water-based
materials or materials with a minimum ash point of
70ºF (21ºC) for spraying or cleaning. Do not spray
or clean with materials having a ash point less
than 70ºF (21ºC), such as solvent based lacquers,
enamels, and/or stain blockers. Flash point is the
temperature at which a uid can produce enough
vapors to ignite.
• Plastic can cause static sparks. Never hang plastic
to enclose a spray area. Do not use plastic drop
cloths when spraying ammable materials.
• Use lowest possible pressure to ush equipment.
• Do not spray onto pump assembly.
HAZARD: EXPLOSION HAZARD DUE TO
INCOMPATIBLE MATERIALS
Will cause property damage or severe injury.
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.
HAZARD: GENERAL
Can cause severe injury or property damage.
PREVENTION:
• Read all instructions and safety precautions before
operating equipment.
• Follow all appropriate local, state, and national
codes governing ventilation, re prevention, and
operation.
• The United States Government Safety Standards
have been adopted under the Occupational
Safety and Health Act (OSHA). These standards,
particularly part 1910 of the General Standards and
part 1926 of the Construction Standards should be

IMPORTANT ELECTRICAL INFORMATION
NOTICE
Use only a 3-wire extension cord that has a 3-blade
grounding plug and a 3-slot receptacle that will accept
the plug on the product. Make sure your extension
cord is in good condition. When using an extension
cord, be sure to use one heavy enough to carry the
current your product will draw. An undersized cord
will cause a drop in line voltage resulting in loss of
power and overheating. A 14 or 12 gauge cord is
recommended (see chart). If an extension cord is to
be used outdoors, it must be marked with the sufx
W-A after the cord type designation. For example, a
designation of SJTW-A would indicate that the cord
would be appropriate for outdoor use.
Wagner Spray Tech accessory extension cords
recommended:
P/N 0090241 20 foot extension cord.
P/N 0090242 35 foot extension cord.
Cord gauge Maximum cord length
12 150 feet
14 100 feet
Do not use more than 50 feet of spray hose. If
you need to spray further than 50 feet from your
power source, use more extension cord, not
more spray hose.
Grounding Instructions
This product must be grounded. In the event of an
electrical short circuit, grounding reduces the risk of
electric shock by providing an escape wire for the

properly installed and grounded in accordance with all
local codes and ordinances.
WARNING - Improper installation of the
grounding plug can result in a risk of
electric shock.
If repair or replacement of the cord or plug
is necessary, do not connect the green
grounding wire to either at blade terminal. The wire
with insulation having a green outer surface with or
without yellow stripes is the grounding wire and must
be connected to the grounding pin.
Check with a qualied electrician or serviceman if the
grounding instructions are not completely understood,
or if you are in doubt as to whether the product is
properly grounded. Do not modify the plug provided.
If the plug will not t the outlet, have the proper outlet
installed by a qualied electrician.
This product is for use on a nominal 120 volt
circuit and has a grounding plug that looks
like the plug illustrated below. Make sure that
the product is connected to an outlet having
the same conguration as the plug. No
adapter should be used with this product.
