immediately.
The maximum operating range of the sprayer is 3000 PSI / 20.7
MPa 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 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 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 3000 PSI / 20.7
MPa. This includes spray tips, guns, extensions, and hose.
• Do not leave the unit energized or under pressure while
unattended. When the unit is not in use, turn off the unit and
relieve the pressure in accordance with the PRESSURE
RELIEF PROCEDURE described in this manual.

high pressure uid stream causing severe injury.
• Always engage the trigger lock when not spraying. Verify
the trigger lock is functioning properly.
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.

necessary protection.
• Wear protective eyewear.
• 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 pump at least 25 feet (7.62 meters) 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.
• 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.
• For electric units — 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.
• Use extreme caution when using materials with
a ashpoint below 70ºF (21ºC). Flashpoint is the
temperature that 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.

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 electric current. This product is
equipped with a cord having a grounding wire with an appropriate
grounding plug. The plug must be plugged into an outlet that
is 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.
IMPORTANT: 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 12
gauge cord is recommended. If an extension cord is to be
used outdoors, it must be marked with the suffix 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.

7. Lock the gun by turning the gun trigger lock
to the locked position.
8. Move the PRIME/SPRAY valve down to the
PRIME position.
Spraying
Keep the spray gun perpendicular to the surface, otherwise one
end of the pattern will be thicker than the other.
The spray gun should be triggered by turning it on and off with
each stroke. This will save paint and avoid paint 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.
NOTE: Whensprayingblockller,masticsorhighsolid
coating,removethegunlterandhighpressure
lterscreens.
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.
Keep the spray gun at right angles to the surface. This means
moving your entire arm back and forth rather than just exing
your wrist.
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. Turn the ON/OFF switch
to the OFF position and unplug the sprayer.
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.
3. Move the PRIME/SPRAY valve up to the
SPRAY position.
4. Turn the pressure control knob clockwise to
its highest setting. The paint hose should
stiffen as paint begins to ow through it.
5. Unlock the gun trigger lock.
6. Trigger the spray gun to bleed air out of the hose.
7. When paint reaches the spray tip, spray a test area to
check the 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 gobs rather than in a ne
spray.

Cleanup
Do not use gasoline to clean the sprayer.
Special cleanup instructions for use with
flammable solvents:
• Always ush spray gun preferably outside and at least one
hose length from spray pump.
• If collecting ushed solvents in a one gallon metal
container, place it into an empty ve gallon container, then
ush solvents.
• Area must be free of ammable vapors.
• Follow all cleanup instructions.
IMPORTANT: The sprayer, hose, and gun should be cleaned
thoroughly after daily use. Failure to do so permits material
to build up, seriously affecting the performance of the unit.
Always spray at minimum pressure with the gun
nozzle tip 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.
1. Follow the “Pressure Relief Procedure” found in the
Operation section of this manual.
2. Remove the gun tip and tip guard and clean with a brush
using the appropriate solvent.
3. Place the siphon tube into a container of the appropriate
solvent. Examples of the appropriate solvent are water for
latex paint or mineral spirits for oil-based paints.
4. Place the return hose into a metal waste container.
5. Set the pressure to minimum by turning the pressure
control knob fully counterclockwise.
6. Move the PRIME/SPRAY valve down to the
PRIME position.
NOTE: Hold the return hose in the waste
container when moving the PRIME/
SPRAY valve to PRIME in case the
sprayer is pressurized.
7. Turn on the sprayer by moving the ON/OFF switch to the
ON position.
8. Allow the solvent to circulate through the sprayer and
ush the paint out of the return hose into the metal waste
container.
9. Turn off the sprayer by moving the ON/OFF
switch to the OFF position.
10. Move the PRIME/SPRAY valve up to its
SPRAY position.
11. Turn on the sprayer.
Ground the gun by holding it
against the edge of the metal
container while flushing. Failure to
do so may lead to a static electric
discharge, which may cause a fire.
12. Trigger the gun into the metal waste container until the
paint is ushed out of the hose and solvent is coming out
of the gun.
13. Continue to trigger the spray gun into the waste container
until the solvent coming out of the gun is clean.
Cleaning the Spray Tip
1. Flush the gun with solvent immediately after the work is
completed.
2. Oil the sliding pins to prevent them from seizing up.
Should the spray tip become clogged, reverse the
spray tip with the lever and pull the trigger. Once
the obstruction comes out of the spray tip, release
the trigger, reverse the spray tip back to the spray
pattern setting, and resume spraying.
Do not attempt to clean the tip with your finger.
Do not use a needle or other sharp pointed
instrument to clean the tip. The hard tungsten
carbide is brittle and can be chipped.
Maintenance
Before proceeding, follow the Pressure Relief
Procedure outlined previously in this manual.
Additionally, follow all other warnings to reduce the
risk of an injection injury, injury from moving parts
or electric shock. Always unplug the sprayer
before servicing!
