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 that 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.
NOTE: Notes give important information which
should be given special attention.
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 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 handle must be turned to PRIME to
relieve the pressure. Refer to the PRESSURE RELIEF
PRESSURE described in the pump 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. 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 3200
PSI/221 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: EXPLOSION ANDFIRE - Solvent and paint
fumes can explode or ignite. Severe injury and/or
property damage can occur.
PREVENTION:
1. Provide extensive exhaust and fresh air introduction
to keep the air within the spray area free from
accumulation of flammable vapors.
2

2. Avoid all ignition sources such as static electricity
sparks, electrical appliances, flames, pilot lights, hot
objects, and sparks from connecting and disconnecting
power cords
3.Do not smoke in spray area.
4.Fire extinguisher must be present and in good
working order.
5.Place pump at least 20 feet (6.1 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.
6. The equipment and objects in and around the spray
area must be properly grounded to prevent static
sparks.
7. Use only conductive or grounded high-pressure fluid
hose. Gun must be grounded through hose
connections.
8. 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.
9.Follow material and solvent manufacturer's
warnings and instructions.
10.Use extreme caution when using materials with a
Flashpoint below 70°F (21℃). Flashpoint is the
temperature at which a fluid can produce enough
vapors to ignite.
11. Plastic can cause static sparks. Never hang plastic
to enclose spray area. Do not use plastic drop cloths
when spraying flammable materials.
12. Use lowest possible pressure to flush equipment.
Earthing 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.
DANGER---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 flat 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 qualified 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 fit the outlet, have the proper outlet
installed by a qualified electrician.

Spraying
POSSIBLE INJECTION HAZARD. Do not spray without the

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 orifice. If there is an
insufficient amount of paint on the surface or you
desire to spray faster, a larger orifice 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.
6

Avoid arcing or holding the gun at an angle. This will
result in an uneven finish.
Proper lapping (overlap of spray pattern) is essential to
an even finish. 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%.
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
receive approximately even amounts of paint.
When spraying with a shield, hold it firmly against the
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.
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.Turn the PRIME/SPRAY valve up to its SPRAY
position.
4.Turn the pressure control knob clockwise to its
highest setting. The paint hose should stiffen as paint
begins to flow 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 fine spray.
7

Cleanup
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.
