READ BEFORE OPERATING
Your new High Volume, Low Pressure (HVLP) Spray gun
complies with the strict California South Coast Air Quality
Management District Rule #1162 along with Air Quality Rules
in other geographical areas. You should also know that the definition of H.V.L.P., as defined in the S.C.A.Q.M.D. Rule #1162
reads, ”High Volume Low Pressure (HVLP) spray is a coating
application system which is operated at air pressure of between
0.1 and 10 pounds per square inch gauge (PSIG).”
To maintain compliance and best results, we suggest:
1. Install air pressure test gauge (207-11799) with adapter in
gun nozzle body.
2. With an air hose connected to the assist air connection on rear
of gun, set assist air pressure to a maximum of 40 psi. Because
of the superb flow characteristics of the gun design, 40 psi
max is all that is ever required with only few exceptions.
3. Open pattern control thumbwheel all the way. Pull trigger
and observe the pressure reading of the test gauge. It should
not exceed 10 psi. Should the test gauge indicate more or
less than 10 psi, increase or decrease regulated air supply
until 10 psi is shown on test gauge while pulling trigger.
You might want to put a “landmark” on your air control
gauge for easy reference. The variables of air hose length
and regulator and gauge types sometimes require that these
adjustments become necessary.
4. Remove test gauge and adapter and install 1/16″ NPT pipe
plug furnished. You are now in compliance for the criteria
HVLP. Should your local Air Quality Officer or Inspector
ever request air pressure reading, co-operate and install test
gauge and demonstrate that your nozzle pressure is 10 psi
or less.
The material transfer efficiency of your 755 HVLP Gun is
excellent but resin and catalyst pressure(s) must also be correctly
set for optimum results.
We suggest:
1. Resin pump pressure should be set as low as possible for an
acceptable spray pattern. Remember the assist air (10 psi)
plays a big part in the final spray pattern shape.
2. Select the proper spray tip for the job. A spray tip with too
small an orifice with excessive resin pump pressure would
result in poor results. It is recommended that a range of
spray tip sizes be on hand to avoid compromises. Your
spray pattern should be a soft, uniform shape without fingers or tails. Resin “bounce back” should not occur.
Catalyst and catalyst atomizing pressures should also be set as
low as possible. Usually, the Catalyst Tank pressure is set at
35-40 psi. Catalyst Fan pressure should be 10 psi lower or
25-30 psi. Flowmeter (black ball) should be adjusted for
desired gel time. A good place to start would be a black ball
reading of between 60-80. Always test spray gun and gel times
on waste material until you’re ready to fabricate parts.
OPERATING INSTRUCTIONS

WARNING
!
In this part sheet, the words WARNING, CAUTION and NOTE are used to emphasize important safety information as follows:
CAUTION
Hazards or unsafe practices which could
result in minor personal injury, product
or property damage.
!
WARNING
Hazards or unsafe practices which could
result in severe personal injury, death or
substantial property damage.
!
NOTE
Important installation, operation or
maintenance information.
Read the following warnings before using this equipment.
FOR FURTHER SAFETY INFORMATION REGARDING BINKS AND DEVILBISS EQUIPMENT,
SEE THE GENERAL EQUIPMENT SAFETY BOOKLET (77-5300).
READ THE MANUAL
Before operating finishing equipment, read and
understand all safety, operation and maintenance
information provided in the operation manual.
PLURAL COMPONENT MATERIALS HAZARD
Because of the vast number of chemicals that could
be used and their varying chemical reactions, the
buyer and user of this equipment must determine
all facts relating to the materials used, including
any of the potential hazards involved.
NOISE HAZARD
You may be injured by loud noise. Hearing protection
may be required when using this equipment.
FIRE AND EXPLOSION HAZARD
Improper equipment grounding, poor ventilation,
open flame or sparks can cause hazardous
conditions and result in fire or explosion and
serious injury.
PINCH POINT HAZARD
Moving parts can crush and cut. Pinch points are
basically any areas where there are moving parts.
KNOW WHERE AND HOW TO SHUT OFF THE
EQUIPMENT IN CASE OF AN EMERGENCY
PRESSURE RELIEF PROCEDURE
Always follow the pressure relief procedure in the
equipment instruction manual.
WEAR SAFETY GLASSES
Failure to wear safety glasses with side shields
could result in serious eye injury or blindness.
DE-ENERGIZE, DEPRESSURIZE, DISCONNECT
AND LOCK OUT ALL POWER SOURCES DURING
MAINTENANCE
Failure to De-energize, disconnect and lock out
all power supplies before performing equipment
maintenance could cause serious injury or death.
OPERATOR TRAINING
All personnel must be trained before operating
finishing equipment.
EQUIPMENT MISUSE HAZARD
Equipment misuse can cause the equipment to
rupture, malfunction, or start unexpectedly and
result in serious injury.
KEEP EQUIPMENT GUARDS IN PLACE
Do not operate the equipment if the safety
devices have been removed.
HIGH PRESSURE CONSIDERATION
High pressure can cause serious injury. Relieve all
pressure before servicing. Spray from the spray
gun, hose leaks, or ruptured components can
inject fluid into your body and cause extremely
serious injury.
3
Do not handle or use until safety precautions
concerning Methyl Ethyl Ketone Peroxides in
the Manufacturer’s literature have been read
and understood.
Contact with foreign materials, especially
strong mineral acids, metals (including certain
equipment and containers) or metal salts, or
exposure to heat above 135° F (57° C) may
lead to violent decomposition, releasing
flammable vapors which may self-ignite.
Do not get into eyes or on skin or clothing.
Wear eye and skin protection when handling.
Avoid breathing mist. Use with adequate
ventilation. Store only it in the original
closed container. Wash hands thoroughly
after handling. Protect from direct sunlight,
heat, sparks and other sources of ignition.
Prevent contamination with foreign materials.
Do not add to hot materials.
To maintain the chemical activity store below
100° F (38° C).
In case of fire, use water spray, foam or dry
chemical.
In case of spill or leak, absorb or blend with
inert, non-combustible material. Put in suitable
container. Dispose of immediately in
accordance with federal, state and local
regulations.
Do not reuse container as some of the original
hazardous contents may still be present.
Follow the above precautions in handling.
HALOGENATED HYDROCARBON
SOLVENTS CAN CAUSE AN EXPLOSION
WHEN IN CONTACT WITH ALUMINUM
COMPONENTS OF A PRESSURIZED OR
CLOSED FLUID SYSTEM (PUMPS,
HEATERS, FILTERS, etc.)
The same possibility of an explosion is possible
with the galvanized coatings in pressure tanks.
The possibility of a non-flammable explosion
increases greatly at high operating temperatures.
The explosion could be of sufficient strength to
cause bodily injury, death, and substantial
property damage.
Cleaning agents, coatings, or adhesives may
contain HALOGENATED HYDROCARBON
SOLVENTS. CHECK WITH YOUR SOLVENT
AND PAINT SUPPLIER.
If you are now using a Halogenated Hydrocarbon
Solvent in a pressurized fluid system with
aluminum components or galvanized wetted
parts, the following steps should be taken
immediately:
1. Remove all pressure; drain and disconnect
the entire system.
2. Inspect and replace all corroded parts.
3. Contact your solvent supplier for a
NON-HALOGENATED SOLVENT to
flush and clean the system of all residues.
HALOGENATED Solvents are defined as any
hydrocarbon solvent containing any of the
following elements:
CHLORINE “CHLORO” (Cl)
BROMINE “BROMO” (Br)
FLUORINE “FLUORO” (F)
IODINE “IODO” (I)
Of those listed, the Chlorinated Solvents will
most likely be the type used as a cleaning agent
or solvent in an adhesive or coating. The most
common are:
METHYLENE CHLORIDE
1,1,1, TRICHLORETHANE
PERCHLORETHYLENE
Although stabilizers have been added to some
of the solvents to reduce their corrosive effect,
we are aware of none that will prevent these
solvents from reacting under all conditions
with aluminum components or galvanized
coatings.
Previous use of the solvents under pressurized
conditions, without incident, does not necessarily
indicate that it can be considered safe.
Model 202-755 GUN is constructed with
components of aluminum alloy
and SHOULD NOT be used with any
Halogenated Hydrocarbon solvents.
