The maximum operating range of the unit is 20.7 MPa
(3000 PSI) 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 your hand in front of the gun. Gloves will not
provide protection against an injection injury.
• ALWAYS lock the gun trigger, shut the fluid pump off and
release all pressure before servicing, cleaning the tip
guard, changing tips, or leaving unattended. Pressure will
not be released by turning off the engine. 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 this 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.
• The 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 sprayer. This includes
spray tips, guns, extensions, and hose.

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.
WARNING
This symbol indicates a potential hazard that may cause
serious injury or loss of life. Important safety information
will follow.
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.
CAUTION
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: EXPLOSION OR 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 sprayer at least 6.1 m (20 feet) 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 earthed high pressure fluid hose.
Gun must be earthed through hose connections.
• Power cord must be connected to a grounded circuit
(electric units only).
• 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.
• The unit must be connected to an earthed object. Use the
green earthing wire to connect the unit to a water pipe,
steel beam, or other electrically earthed surface.
NOTE: Notes give important information which should
be given special attention.
CAUTION
This unit is provided with a thermally protected automatic
reset. If an overload occurs the thermally protected
automatic reset disconnects the motor from the power
supply.
• The motor will restart without warning when the protector
automatically resets.
• Always disconnect the motor from the power supply
before working on the equipment.
• When the thermally protected automatic reset disconnects
the motor from the power supply, relieve pressure by
turning the priming valve to PRIME.
• Turn the ON/OFF switch to OFF.

information.
HAZARD: EXPLOSION HAZARD DUE TO INCOMPATIBLE
MATERIALS - Will cause severe injury or
property damage.
PREVENTION:
• Do not use materials containing bleach or chlorine.
• Do not use halogenated hydrocarbon solvents such as
methylene chloride and 1,1,1 - trichloroethane. They are
not compatible with aluminum and may cause an
explosion. If you are unsure of a material’s compatibility
with aluminum, contact your coating's supplier.
HAZARD: HAZARDOUS VAPORS - Paints, solvents,
insecticides, and other materials can be
harmful if inhaled or come in contact with 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 eyewear.
• Wear protective clothing as required by coating
manufacturer.

injury or property damage.
PREVENTION:
• Read all instructions and safety precautions before
operating equipment.
• Follow all appropriate local, state, and national codes
governing ventilation, fire prevention, and operation.
• Pulling the trigger causes a recoil force to the hand that is
holding the spray gun. The recoil force of the spray gun is
particularly powerful when the tip has been removed and
a high pressure has been set on the airless pump. When
cleaning without a spray tip, set the pressure control knob
to the lowest pressure.
• Use only manufacturer authorized parts. User assumes
all risks and liabilities when using parts that do not meet
the minimum specifications and safety devices of the
pump manufacturer.
• Before each use, check all hoses for cuts, leaks, abrasion
or bulging of cover. Check for damage or movement of
couplings. Immediately replace the hose if any of these
conditions exist. Never repair a paint hose. Replace it
with another earthed high-pressure hose.
• ALWAYS follow the material manufacturer’s instructions
for safe handling of paint and solvents.
• Do not use this unit in workshops that are covered under
the explosion prevention regulations.
• Clean up all material and solvent spills immediately.
• Always unplug cord from outlet before working on
equipment (electric units only).

Earthing Instructions
Electric models must be earthed. In the event of an electrical
short circuit, earthing reduces the risk of electric shock by
providing an escape wire for the electric current. This product
is equipped with a cord having an earthing wire with an
appropriate earthing plug. The plug must be plugged into an
outlet that is properly installed and earthed in accordance with
all local codes and ordinances.
DANGER — Improper installation of the earthing 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
earthing wire to either flat blade terminal. The wire with
insulation having a green outer surface with or without
yellow stripes is the earthing wire and must be connected
to the earthing pin.
Check with a qualified electrician or serviceman if the earthing
instructions are not completely understood, or if you are in
doubt as to whether the product is properly earthed. Do not
modify the plug provided. If the plug will not fit the outlet, have
the proper outlet installed by a qualified electrician.

Spraying
Proper way to trigger the spray gun
Spraying Technique
The key to a good paint job is an even coating over the entire
surface. This is done by using even strokes. Keep your arm
moving at a constant speed and keep the spray gun at a
constant distance from the surface. The best spraying distance
is 10 to 12 inches between the spray tip and the surface.
Light Coat
Heavy Coat
Keep stroke
even
Aproximately
10 to 12 inches
Light Coat
Start stroke
Pull trigger
Keep steady
Release trigger
End stroke
Overlap each stroke by about 30%. This will ensure an even
coating.
When you stop painting, lock the gun trigger lock, turn the
pressure control knob counterclockwise to its lowest setting
and set the PRIME/SPRAY valve to PRIME. Move the motor
ON/OFF switch to OFF and unplug the sprayer.
If you expect to be gone more than 1 hour, follow the short
term clean up procedure described in the CLEANUP section of
this manual.
Do not flex wrist while spraying.
Keep the spray gun at right angles to the surface. This means
moving your entire arm back and forth rather than just flexing
your wrist.
Practice
1. Be sure that the paint hose is free of kinks and clear of
objects with sharp cutting edges.
2. Turn the pressure control knob counterclockwise to its to
its lowest setting.
Even coat throughout
Pressure Control Knob
Approximately
10 to 12 inches
PRIME/SPRAY Valve
Keep stroke smooth and at an even speed.
Keep the spray gun perpendicular to the surface, otherwise
one end of the pattern will be thicker than the other.
3. Turn the PRIME/SPRAY valve to SPRAY.
4. Turn the pressure control knob clockwise to its highest
setting. The paint hose should stiffen as material begins
to flow through it.
5. Unlock the gun trigger
lock by turning the
switch so that it is
parallel to the handle.
Good spray pattern
6. Trigger the spray gun to
bleed air out of the
hose.
7. When material reaches
the spray tip, spray a
test area to check the
Paint tailing pattern
spray pattern.
8. Use the lowest pressure setting necessary to get a good
spray pattern. If the pressure is set too high, the spray
pattern will be too light. If the pressure is set too low,
tailing will appear or the paint will spatter out in blobs
rather than in a fine spray.
Approximately
10 to 12 inches
Right way
Wrong way
The spray gun should be triggered by turning it on and off with
each stroke. This will save material and avoid material buildup
at the end of the stroke. Do not trigger the gun during the
middle of a stroke. This will result in an uneven spray and
splotchy coverage.

5. Cover all parts with a thin coat of light oil before
reassembling.
NOTE: You will need to align the ridge on the seat
with the groove in the pump housing when
reassembling.
6. Drop in the valve ball.
7. Insert the ball stop and spring and replace the valve body.
Be sure that the o-ring is positioned properly and that the
tongue on the cap fits inside the spring.
8. Tighten the valve body securely with an adjustable
wrench. Do not over-tighten.
NOTE: The inlet valve must be oiled after every job.
This will reduce or eliminate priming problems
the next time the sprayer is used.
4. Thoroughly clean the valve assembly with water or the
appropriate solvent. Use a small brush.
5. If the valve has been properly cleaned and water drips out
of the bottom, the valve is worn and needs to be replaced.
A properly seated valve filled with water and held vertically
will not drip.
6. Install a new or cleaned valve in the pump block and then
fill the valve with light oil or solvent.

Cleaning the Hopper Screen
The screen at the bottom of the paint hopper
may need cleaning periodically. Check it
every time you add paint. Remove the
screen by pulling it out of the hopper with a
pliers. Clean the screen with water or
solvent and a soft-bristle brush, if necessary.
