IMPORTANT SAFETY INSTRUCTIONS
INSTRUCTIONS PERTAINING TO A RISK OF FIRE,
ELECTRIC SHOCK, OR INJURY TO PERSONS
The warnings and precautions discussed in this manual cannot cover all possible conditions and
situations that may occur. It must be understood by the operator that common sense and caution
are factors which cannot be built into this product, but must be supplied by the operator.
WARNING – When using tools, basic precautions should always be followed, including the following:
Work Area
a. Keep the work area clean and well lighted.
Cluttered benches and dark areas
increase the risks of electric shock,
fire, and injury to persons.
Page 2 For technical questions, please call 1-800-444-3353. Item 69704
b. Keep bystanders, children, and
visitors away while operating the tool.
Distractions are able to result in
the loss of control of the tool.
Delayed or inadequate cleaning will permanently clog the Spray Gun.
Personal Safety
NOTICE
Clean the Spray Gun IMMEDIATELY after use.
a. Stay alert. Watch what you are
doing and use common sense when
operating the tool. Do not use the
tool while tired or under the influence
of drugs, alcohol, or medication.
A moment of inattention while operating the
tool increases the risk of injury to persons.
b. Dress properly. Do not wear loose clothing
or jewelry. Contain long hair.
Keep hair, clothing, and gloves away
from moving parts. Loose clothes, jewelry, or
long hair increases the risk of injury to persons
as a result of being caught in moving parts.
Tool Use and Care
a. Do not force the tool. Use the correct
tool for the application. The correct tool
will do the job better and safer at the
rate for which the tool is designed.
b. Disconnect the tool from the air source
before making any adjustments,
changing accessories, or storing the tool.
Such preventive safety measures reduce
the risk of starting the tool unintentionally.
Turn off and detach the air supply, safely
discharge any residual air pressure, and
release the throttle and/or turn the switch to
its off position before leaving the work area.
c. Do not overreach. Keep proper
footing and balance at all times.
Proper footing and balance enables better
control of the tool in unexpected situations.
d. Use safety equipment.
Wear heavy-duty work gloves and
a NIOSH-approved respirator
during use. Non-skid safety shoes
and a hard hat must be used for the
applicable conditions.
e. Always wear eye protection.
Wear ANSI-approved
safety goggles.
c. Store the tool when it is idle out of reach
of children and other untrained persons.
A tool is dangerous in the hands
of untrained users.
d. Check for misalignment or binding of
moving parts, breakage of parts, and any
other condition that affects the tool’s
operation. If damaged, have the tool serviced
before using. Many accidents are caused
by poorly maintained tools. There is a risk
of bursting if the tool is damaged.
e. Use only accessories that are identified
by the manufacturer for the specific
tool model. Use of an accessory not
intended for use with the specific tool model,
increases the risk of injury to persons.
SAFETYOPERATIONMAINTENANCE SETUP
Service
a. Tool service must be performed only
by qualified repair personnel.
b. When servicing a tool, use only
identical replacement parts.
Use only authorized parts.
c. Use only lubricants supplied with the
tool or specified by the manufacturer.

Air Source
NOTICE
Clean the Spray Gun IMMEDIATELY after use.
Delayed or inadequate cleaning will permanently clog the Spray Gun.
a. Never connect to an air source
serious injury to persons. Use only clean, dry,
regulated compressed air at the rated pressure
or within the rated pressure range as marked
on the tool. Always verify prior to using the
tool that the air source has been adjusted to
the rated air pressure or within the rated
air-pressure range.
that is capable of exceeding
200 psi. Over pressurizing the tool
may cause bursting, abnormal

Specific Safety Instructions
NOTICE
1. Do not direct spray at people or animals.
2. Do not exceed maximum air pressure.
3. Do not spray near open flames, pilot lights,
stoves, heaters, the air compressor, or
any other heat source. Most solvents and
coatings are highly flammable, particularly
when sprayed. Maintain a distance of at least
25 feet from the air compressor. If possible,
locate the air compressor in a separate room.
4. Read all of the information concerning
coating products and cleaning solvents.
Do not use chlorinated solvents
(e.g. 1-1-1 trichloroethylene and
dichloromethane, also known as
methylene chloride) to clean spray guns.
Many spray guns contain aluminum,
which reacts strongly to chlorinated
solvents. Contact the solvent or coating
manufacturer as needed regarding
potential chemical reactions.
5. Industrial applications must
follow OSHA requirements.
6. Spraying hazardous materials may
result in serious injury or death.
Do not spray pesticide, acid, corrosive
material, fertilizer, or toxic chemicals.
7. Paints and solvents may be harmful or fatal if
swallowed or inhaled. Avoid prolonged skin
contact with solvents or paints as they will
irritate skin. After any contact, immediately
wash off exposed area with hot, soapy water.
8. Attach all accessories properly to the
tool before connecting the air supply.
A loose accessory may detach
or break during operation.
9. Install an in-line shutoff valve
to allow immediate control over
the air supply in an emergency,
even if a hose is ruptured.
10. Air hose fittings may get hot during use.
Allow fittings to cool before disconnecting.
11. WARNING: Some dust created by power
sanding, sawing, grinding, drilling, and
other construction activities, contains
chemicals known [to the State of California]
to cause cancer, birth defects or other
reproductive harm.
Some examples of these chemicals are:
• Lead from lead-based paints
• Crystalline silica from bricks and cement or
other masonry products
• Arsenic and chromium from
chemically treated lumber
Your risk from these exposures varies,
depending on how often you do this type
of work. To reduce your exposure to these
chemicals: work in a well ventilated area, and
work with approved safety equipment, such as
those dust masks that are specially designed
to filter out microscopic particles.
(California Health & Safety Code
§ 25249.5, et seq.)
WARNING: The brass components of
this product contain lead, a chemical
known to the State of California to cause
birth defects (or other reproductive harm).

SAFETY OPERATION MAINTENANCESETUP
Initial Set Up
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this
manual including all text under subheadings therein before set up or use of
this product.
Note: For additional information regarding the parts listed in the following
pages, refer to the Assembly Diagram near the end of this manual.
Before Setup
Clean the Spray Gun IMMEDIATELY after use.
1. This air tool may be shipped with a
protective plug covering the air inlet.
Remove this plug before set up.
Air Supply Setup
TO PREVENT SERIOUS INJURY FROM EXPLOSION:
Use only clean, dry, regulated, compressed air to power this tool. Do not use
oxygen, carbon dioxide, combustible gases, or any other bottled gas as a power
source for this tool.
1. Incorporate a filter, regulator with pressure
gauge, in-line shutoff valve, and quick coupler
for best service, as shown on Figure A on
page 7 and Figure B on page 8.
An in-line shutoff ball valve is an important
safety device because it controls the air
supply even if the air hose is ruptured.
The shutoff valve should be a ball valve
because it can be closed quickly.
Note: Do not use an automatic oiler system or
add oil to airline. The oil will contaminate the
material being propelled, ruining the final result.
2. Attach an air hose to the
compressor’s air outlet. Connect the
air hose to the air inlet of the tool.
Other components, such as a coupler plug
and quick coupler, will make operation
more efficient, but are not required.
2. Before first use, clean the Spray Gun using
a solvent-based thinner. If not removed,
the material used for testing and corrosion
prevention will contaminate paint.
WARNING! TO PREVENT SERIOUS INJURY
FROM ACCIDENTAL OPERATION:
Do not install a female quick coupler
on the tool. Such a coupler contains
an air valve that will allow the air tool to
retain pressure and operate accidentally
after the air supply is disconnected.
Note: Air flow, and therefore tool
performance, can be hindered by
undersized air supply components.
3. The air hose must be long enough to reach
the work area with enough extra length
to allow free movement while working.
4. Close the in-line shutoff valve between
the compressor and the tool.
5. Turn on the air compressor according to
the manufacturer’s directions and allow it
to build up pressure until it cycles off.
