immediately.
The maximum operating range of the sprayer is 3300 PSI / 22.8
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 3300 PSI / 22.8
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.

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.

Be sure to follow the pressure relief procedure
when shutting the unit down for any purpose,
including servicing or adjusting any part of the
spray system, changing or cleaning spray tips, or
preparing for cleanup.
1. Lock the gun by turning the gun
trigger lock to the locked position.
2. Turn off the sprayer by moving the
ON/OFF switch to the OFF position.
3. Turn the pressure control knob
counterclockwise to its OFF position
in the black zone.
4. Unlock the gun by turning the gun trigger lock to the
unlocked position.
5. Hold the metal part of the gun rmly
to the side of a metal container to
ground the gun and avoid a build up
of static electricity.
6. Trigger the gun to remove any

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.
Avoid arcing or holding the gun at an angle. This will result in an
uneven nish.
Proper lapping (overlap of spray pattern) is essential to an even
nish. Lap each stroke. If you are spraying horizontally, aim
at the bottom edge of the preceding stroke, so as to lap the
previous pattern by 50%.
Spraying
POSSIBLE INJECTION HAZARD. Do not spray
without the tip guard in place. Never trigger the
gun unless the tip is in either the spray or the
unclog position. Always engage the gun trigger
lock before removing, replacing, or cleaning tip.
Spraying Technique
The following techniques, if followed, will assure professional
painting results.
Hold the gun perpendicular to the surface and always at equal
distance from the surface. Depending on the type of material,
surface, or desired spray pattern, the gun should be held at a
distance of 12 to 14 inches (30 to 35 cm).
Move the gun either across or up and down the surface at a
steady rate. Moving the gun at a consistent speed conserves
material and provides even coverage. The correct spraying speed
allows a full, wet coat of paint to be applied without runs or sags.
Holding the gun closer to the surface deposits more paint on
the surface and produces a narrower spray pattern. Holding the
gun farther from the surface produces a thinner coat and wider
spray pattern. If runs, sags, or excessive paint occur, change to
a spray tip with a smaller orice. If there is an insufcient amount
of paint on the surface or you desire to spray faster, a larger
orice tip should be selected.
Maintain uniform spray stroke action. Spray alternately from left
to right and right to left. Begin movement of the gun before the
trigger is pulled.
For corners and edges, split the
center of the spray pattern on
the corner or edge and spray
vertically so that both adjoining
sections receive approximately
even amounts of paint.
When spraying with a shield, hold it rmly against the surface.
Angle the spray gun slightly away from the shield and toward the
surface. This will prevent paint from being forced underneath.
Shrubs next to houses should be tied back and covered with a
canvas cloth. The cloth should be removed as soon as possible.
Titan gun extensions are extremely helpful in these situations.
Nearby objects such as automobiles, outdoor furniture, etc.
should be moved or covered whenever in the vicinity of a spray
job. Be careful of any other surrounding objects that could be
damaged by overspray.

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
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.
