MODEL 550
AUTOMATIC AIRLESS SPRAY GUN
6700-0000-5 – FOR PROFESSIONAL USE ONLY
WARNING — HIGH PRESSURE — WARNING
MAXIMUM WORKING PRESSURE UP TO 3000 POUNDS PER SQUARE INCH
• DO NOT POINT SPRAY GUN AT ANY PART OF THE HUMAN BODY
• FLUID UNDER HIGH PRESSURE CAN PENETRATE THE SKIN AND CAUSE SEVERE INTERNAL INJURY
• IN CASE OF INJURY OBTAIN MEDICAL ATTENTION IMMEDIATELY
• BE SURE TO REPORT NATURE OF INJURY AND TYPE OF FLUID OR SOLVENT TO THE DOCTOR
Be sure you understand ALL of the following instructions thoroughly
BEFORE operating any part of the airless equipment system.
CONSULT YOUR BINKS REPRESENTATIVE TO CLEAR UP ANY ITEMS
OF INSTRUCTION YOU DO NOT UNDERSTAND.
1. UNDER NO circumstances should the spray gun be carelessly
handled nor its spray (even when the nozzle is removed) directed
at close proximity to any part of the human body.
2. DO NOT operate airless spray gun with tip guard housing
removed or altered.
3. NEVER clean, change, or remove the nozzle from the
spray gun without first doing the following:
a. Shut off pump and, in addition, unplug electrical cord or turn
off air supply.
b. Release fluid pressure in the entire system, from pump or
supply line to spray gun.
4. NEVER attempt to force the flow of liquid backward through the
gun (blowback) with your finger, hand, or hand-held object
pressed against the gun nozzle.
INSTALLATION AND OPERATING INSTRUCTIONS
Your new Binks 550 Automatic Airless Spray Gun has been
thoroughly tested before leaving the factory. No adjustments are
required before spray operations begin other than installing the
nozzle tip selected. The gun body has four holes which allow the
material body to be mounted in any of four positions for convenient
fluid hose hookup.
The following steps are recommended for obtaining best results from
your spray gun:
1. Install spray gun on gun mount and tighten the set screw (9)
securely. Note: The mounting hole is 1/2" diameter.
2. Connect air hose to fitting (16). The gun is actuated by air
pressure from a 3-way valve. The valve provides air to trigger,
shut-off, and exhausts air from the gun. The gun should be
limited to 200 cycles per minute (maximum). Approximately 40 to
60 psi air pressure is required to operate the spray gun; however,
use the minimum air pressure required.
3. Connect high pressure airless fluid hose to the gun material body
assembly (7) and tighten.
4. Remove tip guard assembly (4), nozzle tip, and gasket (3) from
spray gun (or remove Twist-Tip if used). Turn on air supply to
operate air valve to spray gun. Turn on material supply very
slowly and allow spray gun to trigger a few times to purge any
entrapped air in fluid system.
5. NEVER plug a hose leak with your finger, with adhesive tape, or
other “stop-gap” device.
6. NEVER operate the airless system with a defective hose. ALWAYS
replace the defective hose immediately. For continuing safety,
users are urged to:
a. ALWAYS handle carefully all hose connections, joints, and
seating surfaces on the spray gun to prevent damage.
b. NEVER kink or bend the fluid hose into less than a four inch
radius.
c. FREQUENTLY check the hose for kinks or abrasions. These
may develop into a rupture.
d. NEVER use standard hardware to modify the airless system.
ALWAYS use Binks high pressure fittings only.
7. The airless pump must be grounded before operating the airless
spray system.
5. Shut fluid supply and air supply OFF.
6. Replace gasket (3), nozzle tip, and tip guard assembly (4)
(or Twist-Tip) as per safety procedure described in paragraph 3
above.
7. Turn air and fluid supply ON and check the spray pattern for
proper atomization.
NOTE
When the pattern is right, the pressure is right. Excessive
fluid pressure will only distort the spray pattern.
8. The spray gun nozzle should be located at such a distance to the
product where maximum fan pattern width is evident. This is
usually 8" to 14". The spray pattern may be positioned either
vertically or horizontally by rotating nozzle tip (or the Twist-Tip).
9. “Hour glass” or “tails” on the spray pattern normally indicates too
low a fluid pressure for the nozzle tip being used; or, the material
is too viscous.
10. A distorted spray pattern usually means a plugged or worn nozzle
tip.
11. Using excesive fluid pressure will only cause undue wear of the
nozzle tip.

you are using.
FIRE AND EXPLOSION HAZARD
Improper equipment grounding, poor ventilation, open flame or
sparks can cause a hazardous condition and result in fire or
explosion and serious injury.
MEDICAL ALERT
Any injury caused by high pressure liquid can be serious. If you
are injured or even suspect an injury:
• Go to an emergency room immediately.
• Tell the doctor you suspect an injection injury.
• Show the doctor this medical information or the medical alert
card provided with your airless spray equipment.
• Tell the doctor what kind of fluid you were spraying or
dispensing.
GET IMMEDIATE MEDICAL ATTENTION
To prevent contact with the fluid, please note the following:
• Never point the gun/valve at anyone or any part of the body.
• Never put hand or fingers over the spray tip.
• Never attempt to stop or deflect fluid leaks with your hand,
body, glove or rag.
• Always have the tip guard on the spray gun before spraying.
• Always ensure that the gun trigger safety operates before
spraying.
