INSTRUCTIONS
INSTRUCTIONS PERTAINING
TO A RISK OF FIRE,
ELECTRIC SHOCK, OR
INJURY TO PERSONS
WARNING – When using tools, basic pre-
cautions should always be followed,
including the following:
General
a. To reduce the risks of electric
shock, re, and injury to persons,
read all the instructions before using the tool.
Work area
a. Keep the work area clean and well
lighted. Cluttered benches and dark
areas increase the risks of electric
shock, re, and injury to persons.
b. Do not operate the tool in explo-
sive atmospheres, such as in the
presence of ammable liquids,
gases, or dust. The tool is able to
create sparks resulting in the ignition
of the dust or fumes.
c. Keep bystanders, children, and
visitors away while operating the

tool. Distractions are able to result in
the loss of control of the tool.
Personal safety
a. Stay alert. Watch what you are do-
ing and use common sense when
operating the tool. Do not use the
tool while tired or under the inuence of drugs, alcohol, or medication. A moment of inattention while
operating the tool increases the risk
of injury to persons.
b. Avoid unintentional starting. Be
sure the trigger is released before
connecting to the air supply. Do not
carry the tool with your nger on the
trigger or connect the tool to the air
supply with the trigger depressed.
Tool use and care
a. Use clamps or another practical
way to secure and support the
workpiece to a stable platform.
Holding the work by hand or against
the body is unstable and is able to
lead to loss of control.
b. 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.
c. Do not use the tool if the trigger
does not turn the tool on or off.
Any tool that cannot be controlled
with the trigger is dangerous and
must be repaired.
c. Remove adjusting keys and
wrenches before turning the tool
on. A wrench or a key that is left
attached to a rotating part of the tool
increases the risk of personal injury.
d. Do not overreach. Keep proper
footing and balance at all times.
Proper footing and balance enables
better control of the tool in unexpected situations.
e. Use safety equipment. A
dust mask, non-skid safety
shoes and a hard hat must
be used for the applicable
conditions. Wear heavy-duty work
gloves during use.
f. Always wear eye protec-
tion. Wear ANSI-ap-
proved safety goggles.
d. 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 trigger before leaving
the work area.
e. 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.
f. Maintain the tool with care. Keep
tools clean for better and safer
performance. Follow instructions for
lubricating and changing accessories.
Inspect tool cords and air hoses periodically and, if damaged, have them
repaired by an authorized technician.
The handle must be kept clean, dry,
and free from oil and grease at all
times.

g. Disconnect air supply. Discon-
nect air hose when not in use, when
changing accessories, and during
maintenance.
h. Check for misalignment or bind-
ing of moving parts, breakage of
parts, and any other condition that
affects the tool’s operation. If dam-
aged, 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.
i. Use only accessories that are
identied by the manufacturer for
the specic tool model. Use of an
accessory not intended for use with
the specic tool model, increases the
risk of injury to persons.
Service
a. Tool service must be performed
only by qualied repair personnel.
air source has been adjusted to the
rated air pressure or within the rated
air-pressure range.
b. Never use oxygen, carbon dioxide,
combustible gases or any bottled
gas as an air source for the tool.
Such gases are capable of explosion
and serious injury to persons.
c. Use proper size and type exten-
sion cord. If an extension cord is re-
quired for the compressor, it must be
of the proper size and type to supply
the correct current to the compressor
without heating up. Otherwise, the
extension cord could melt and catch
re, or cause electrical damage to the
compressor. Check your compressor’s manual for the appropriate size
cord.
SAVE THESE
INSTRUCTIONS.
b. When servicing a tool, use only
identical replacement parts. Use
only authorized parts.
c. Use only the lubricants supplied
with the tool or specied by the
manufacturer.
Air source
a. Never connect to an air
source that is capable of
exceeding 200 PSI. Over
pressurizing the tool may
cause bursting, abnormal operation,
breakage of the tool or 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

spray guns. Many spray guns
contain aluminum, which reacts
strongly to chlorinated solvents. If
you have any doubt about potential
chemical reactions, contact the solvent or coating manufacturer.
5. Materials used when painting or
cleaning may be harmful or fatal if
inhaled or swallowed. Only use in an
area with adequate ventilation. Use
a NIOSH-approved respirator when
painting or using cleaning solvents.
Specic Safety Instructions
1. Thoroughly clean the spray gun
out after every use. Improper
cleaning of the Spray Gun is a
common reason for the Spray Gun
to jam or not perform properly.
2. 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.
3. Do not spray near open ames, pilot
lights, stoves, heaters, the air compressor, or any other heat source.
Most solvents and coatings are
highly ammable, 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 Trichlorethylene and Methylene Choride, also
know as methyl chloride) to clean
6. Do not release spray gun lid while
cup is pressurized.
7. Industrial applications must follow
OSHA requirements.
8. Do not point a spray gun at a person
or animal. Serious injury could occur.
9. Spraying hazardous materials may
result in serious injury or death. Do
not spray pesticides, acids, corrosive
materials, fertilizers, and toxic chemicals.
10. 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
