Setup
1. Shut off the air supply.
2. Connect a clean, dry, filtered air supply to
the air inlet fitting (25). See page 10.
3. If this is the first time using the equipment,
flush the gun. See page 5.
Operation
Pressure Relief Procedure
1. Turn off the gun air supply.
2. Trigger the gun to relieve pressure.
Spraying
1. Fill the cup with material. Do not fill past the
shoulder on cup.
2. Turn on the shop air to the gun and set
atomizing pressure with the gun fully
triggered.
3. Adjust the pattern size and shape with the
fluid adjust knob (8). Fluid adjust knob (8) is
factory set for maximum needle trigger
travel and material flow. Turn knob
clockwise to reduce pattern size/ fluid flow
and counterclockwise to increase it.
PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when operating, servicing, or when in
the operating area of the equipment to help protect you from serious injury, including
eye injury, inhalation of toxic fumes, burns, and hearing loss. This equipment includes
but is not limited to:
•
Protective eyewear
•
Clothing and respirator as recommended by the fluid and solvent manufacturer
•
Gloves
•
Hearing protection
WARNING
•
Check that your shop air provides
adequate air flow.
•
Use a minimum 3/8 in. (10 mm) ID air
hose.
•
Set shop air pressure regulator (not
supplied) according to paint manu-
facturer’s recommendation. See
maximum pressures and compliant
air pressures on page 2.
•
Make sure no air restrictions, such as
low-volume cheater-valves, obstruct
the air flow. If an air adjusting valve is
desired, use a Graco Air Adjusting
Valve (288744 or 234387).
•
Install a shutoff valve (not supplied)
downstream of the air regulator to
shut off gun air.
•
Install an inline air filter (not supplied)
to clean and dry the gun air supply.
CAUTION
Excessive atomizing air pressure can
increase over-spray, reduce transfer
efficiency, and result in a poor quality finish.
Regulatory agencies in certain states
prohibit the operation of a spray gun above
10 psi (69 kPa, 0.7 bar) atomizing air cap
pressure.
See Troubleshooting, page 7, if you expe-
rience an irregular pattern.
