SPRAY GUN CLEANING INSTRUCTIONS
In certain states it is now against the law to spray sol-
vents containing Volatile Organic Compounds (VOC)
into the atmosphere when cleaning a spray gun.
In order to comply with these new air quality laws,
Binks recommends one of the two following methods to
clean your spray finishing equipment:
1. Use an enclosed clean-up station or enclosure which
will condense and collect VOC vapors to prevent
their atmospheric release.
2. Use a washer unit. Your gun washer should com-
pletely enclose the spray gun, filter, nozzles and
other parts during wash, rinse and drain cycles to
prevent the release of VOC vapors into the atmo-
sphere.
To further protect the environment, avoid storing sol-
vents or solvent-soaked wipes, such as those used for
surface preparation and clean-up, in open or absorbent
containers.
To clean the gun, flush the fluid lines with solvent and
blow air through the air liens to make sure all the air
passages are dry.
Never completely submerge the gun in solvent as this will
dissolve the lubricating oil and dry out the seals.

CAUTION
TROUBLESHOOTING
FAULTY SPRAY
A faulty spray may be caused by improper cleaning,
dried materials around the fluid nozzle tip or in the
air nozzle. Soak these parts in thinners that will
soften the dried material and remove with a brush
or cloth.
Never use metal instruments to clean the air or fluid
nozzles, these parts are carefully machined and any
damage to them will cause faulty spray.
!
CAUTION
If either the air nozzle (2) or fluid nozzle (3) are
damaged, these parts must be replaced before per-
fect spray can be obtained.
FAULTY SPRAY
If the spray flutters, it is caused by one of the fol-
lowing faults:
1. Insufficient material available. Check supply and
replenish if necessary.
2. Loosen fluid nozzle (3). Tighten but without
using undue force (100-120 in. lbs. torque).
3. Leakage at gland adapter (39) and needle seal
(40). Tighten packing nut (43) if loose, and
replace gland adapter and needle seal if neces-
sary.
4. Fluid connection insufficiently tight or dirt on
cone faces of connection. Correct as necessary.
5. Leaking cylinder air and/or inadequate pressure.
6. Inadequate fluid pressure.
IMPORTANT REGULATORY NOTE
Some Regulatory Agencies prohibit the operation of HVLP spray guns above 10 psi nozzle atomizing pressure.
Users subject to this type of regulation should not exceed the gun inlet pressure indicated on the air cap and/or
in these instructions. See Air Pressure Recommendations, Pages 9 and 10 and General Spray Instructions, Page 8.
It is recommended that the nozzle test gauge shown above, be used to confirm actual nozzle operating pressure.
It may also be a requirement of some Regulatory Agencies that users have this air nozzle test gauge assembly
available on site to verify that the gun is being operated within the limits of applicable rules.
