7. Always use a pressure regulator on
the air supply to the spray gun.
Failure to install
appropriate
water/oil removal equipment may
result in damage to machinery or
workpiece.
Do not misuse this
product. Excessive
exposure to vibration, work in
awkward positions, and repetitive
work motions can cause injury to
hands and arms. Stop using any tool if
discomfort, numbness, tingling, or pain
occur, and consult a physician.
CALIFORNIA PROPOSITION 65
You can create dust when
you cut, sand, drill or grind
materials such as wood,
paint, metal, concrete,
cement, or other masonry. This dust
often contains chemicals known to
cause cancer, birth defects, or other
reproductive harm. Wear protective
gear.

USE OF AIR CAPS
Internal Mix—Generally
used with slow drying,
heavy bodied materials
and for faster material
application. NOT to be
used with fast drying paints and
lacquers which will clog the opening in
the air cap.
INTERNAL MIX CAPS
MUST BE USED WITH PRESSURE
FEED OPERATION.
External Mix—Used for
quick drying, light bodied
materials such as lacquers
and synthetic enamels.
Better for finer finish work.
THESE CAPS CAN BE USED WITH
EITHER SIPHON OR PRESSURE FEED.
FAN DIRECTION
The direction of the fan (horizontal or
vertical) can be changed by loosening
the lock ring and turning the air cap 90
degrees (See Figure 1). Hand tighten
lock ring after adjustment.

included with this
product carefully. Be
thoroughly familiar
with the controls and
the proper use of the equipment.
2. Follow all local electrical and safety

WARNING
Use a face mask/respirator
and protective clothing
when spraying. Always
spray in a well ventilated area to
prevent health and fire hazards. Refer
to Material Safety Data Sheets (MSDS)
of spray material for details.
Never spray closer than 25
feet to the compressor! If
possible, locate
compressor in separate room. Never
spray into the compressor, compressor
controls or the motor.
3. Do not smoke or eat when spraying
paint, insecticides, or other
flammable substances.
Do not spray flammable
materials in vicinity of
open flame or near
ignition sources. Motors, electrical
equipment and controls can cause
electrical arcs that will ignite a
flammable gas or vapor. Never store
flammable liquids or gases in the
vicinity of the compressor.
4. When spraying and cleaning, always
follow the instructions and safety
precautions provided by the material
manufacturer (Refer to MSDS).
Do not spray acids,
corrosive
materials, toxic chemicals, fertilizers or
pesticides. Using these materials could
result in death or serious injury.
5. Keep visitors away and NEVER allow
children or pets in the work area.
Never aim or
spray at yourself
or anyone else or serious injury could
occur.
6. Always work in a clean environment.
To avoid injury and damage to the
workpiece, do not aim the spray gun
at any dust or debris.
Do not use pressure that
exceeds the operating
pressure of any of the
parts (hoses, fittings, etc.) in the
painting system.
Keep hose away
from sharp
objects. Bursting air hoses may cause
injury. Examine air hoses regularly and
replace if damaged.
