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.

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. 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.

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.

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

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. Coatings and solvents may be harmful
or fatal if swallowed or inhaled. Avoid
prolonged skin contact with solvents or
coatings 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.

§ 25249.5, et seq.)

WARNING: The brass components of
this product contain lead, a chemical
known to the State of California to cause
