SAFETY PRECAUTIONS
This manual contains information that is important for you to know and understand. This information relates to USER SAFETY and
PREVENTING EQUIPMENT PROBLEMS. To help you recognize this information, we use the following symbols. Please pay particular
attention to these sections.
NOTE
Important safety information – A hazard
that may cause serious injury or loss
of life.
Important information that tells how
to prevent damage to equipment,
or how to avoid a situation that may
cause minor injury.
Information that you should pay special
attention to.
CA PROP
The following hazards may occur during the normal use of this equipment.
Please read the following chart before using this equipment.
65
PROP 65 WARNING
WARNING: This product contains
chemicals known to the State of
California to cause cancer and birth
defects or other reproductive harm.
HAZARD
CAUSE
SAFEGUARDS
Fire
Solvent and coatings can be highly flammable
or combustible especially when sprayed.
Adequate exhaust must be provided to keep air free of
accumulations of flammable vapors.
Smoking must never be allowed in the spray area.
Fire extinguishing equipment must be present in the spray area.
Solvent Spray
During use and while cleaning and flushing,
solvents can be forcefully expelled from fluid
and air passages. Some solvents can cause
eye injury.
Wear eye protection.
Inhaling Toxic Substances
Certain materials may be harmful if inhaled, or
if there is contact with the skin.
Follow the requirements of the Material Safety Data Sheet
supplied by your coating material manufacturer.
Adequate exhaust must be provided to keep the air free of
accumulations of toxic materials.
Use a mask or respirator whenever there is a chance of inhaling
sprayed materials. The mask must be compatible with the material being sprayed and its concentration. Equipment must be as
prescribed by an industrial hygienist or safety expert, and be
NIOSH approved.
Explosion Hazard Incompatible Materials
Halogenated hydrocarbon solvents - for
example; methylene chloride and 1,1,1, Trichloroethane are not chemically compatible
with the aluminum that might be used in many
system components. The chemical reaction
caused by these solvents reacting with
aluminum can become violent and lead to an
equipment explosion.
Guns with stainless steel internal passageways may be used
with these solvents. However, aluminum is widely used in other
spray application equipment - such as material pumps, regulators, valves, and this gun and cup. Check all equipment items before use and make sure they can also be used safely with these
solvents. Read the label or data sheet for the material you intend
to spray. If in doubt as to whether or not a coating or cleaning
material is compatible, contact your material supplier.
General Safety
Improper operation or maintenance of
equipment.
Operators should be given adequate training in the safe use
and maintenance of the equipment (in accordance with the
requirements of NFPA-33, Chapter 15). Users must comply with
all local and national codes of practice and insurance company
requirements governing ventilation, fire precautions, operation,
maintenance, and housekeeping. These are OSHA Sections
1910.94 and 1910.107 and NFPA-33.
Cumulative Trauma
Disorders ("CTD's")
Use of hand tools may cause cumulative
trauma disorders ("CTD's").
Pain, tingling, or numbness in the shoulder, forearm, wrist,
hands, or fingers, especially during the night, may be early
symptoms of a CTD. Do not ignore them. Should you experience
any such symptoms, see a physician immediately. Other early
symptoms may include vague discomfort in the hand, loss of
manual dexterity, and nonspecific pain in the arm. Ignoring early
symptoms and continued repetitive use of the arm, wrist, and
hand can lead to serious disability. Risk is reduced by avoiding
or lessening factors 1-7.
CTD's, or musculoskeletal
disorders, involve damage
to the hands, wrists,
elbows, shoulders, neck,
and back. Carpal tunnel
syndrome and tendonitis
(such as tennis elbow or
rotator cuff syndrome) are
examples of CTD's.
CTD's, when using hand tools, tend to affect the
upper extremities. Factors which may increase
the risk of developing a CTD include:
1. High frequency of the activity.
2. Excessive force, such as gripping, pinching,
or pressing with the hands and fingers.
3. Extreme or awkward finger, wrist, or arm
positions.
4. Excessive duration of the activity.
5. Tool vibration.
6. Repeated pressure on a body part.
7. Working in cold temperatures.
CTD's can also be caused by such activities
as sewing, golf, tennis, and bowling, to name
a few.

FLG4 SIPHON / PRESSURE FEED SPRAY GUNS AND DeKUPS® DISPOSABLE CUP SYSTEM
IMPORTANT: Before using this equipment, read all safety
precautions on page 2 and instructions. Keep for future use.
Halogenated hydrocarbon solvents - for example; 1, 1,
1- trichloroethane and methylene chloride - can chemically react with the aluminum in this gun and cause an
explosion hazard. Read the label or data sheet for the
material you intend to spray. Do not use spray materials
containing these solvents with this spray gun.
IMPORTANT: This gun may be used with most common coating
and finishing materials. It is designed for use with mildly corrosive
and non-abrasive materials. If used with other high corrosive or
abrasive materials, it must be expected that frequent and thorough cleaning will be required and the necessity for replacement
of parts will be increased.
OPERATION
Strain material thru 60 or 90 mesh screen.
Model FLG-CNS-115:
The No. 1 (conventional) air cap requires an air supply at the gun
inlet of approximately 45 psi, measured with the trigger pulled
and can be operated from a 3 H.P. compressor.
HVLP Models FLG-HVS-322 and
FLG-HVP-315:
The No. 3 (HVLP) air cap requires an air supply at the gun inlet of
23 psi max., measured with the trigger pulled.
This gun was manufactured to provide maximum transfer efficiency
by limiting air cap pressure to 10 psi (complies with rules issued
by SCAQMD and other air quality authorities).
This gun will produce approximately 10 psi cap pressure at 23 psi
inlet pressure, as measured at the gun inlet. An air cap test kit (see
ACCESSORIES) should be used to ensure 10 psi cap pressure is
not exceeded.
Adjust fluid pressure to deliver the desired paint volume. Adjust
air pressure and fluid flow to provide a uniform dispersion of atomized paint throughout the pattern. Keep air pressure as low as
possible to minimize bounce - back and overspray. Excessive air
pressure will result in split patterns. Low air pressure will result in
heavy centered patterns and poor atomization. Excessive fluid flow
will result in heavy center spray patterns. Inadequate fluid flows
may cause the pattern to split. See "TROUBLESHOOTING" section.
PREVENTIVE MAINTENANCE
To clean air cap and fluid tip, brush exterior with a stiff bristle brush.
If necessary to clean cap holes, use a broom straw or toothpick if
possible. If a wire or hard instrument is used, extreme care must
be used to prevent scratching or burring of the holes which will
cause a distorted spray pattern.
To clean fluid passages, remove excess material at source, then
flush with a suitable solvent. Wipe gun exterior with a solvent
dampened cloth. Never completely immerse in solvent as this
is detrimental to the lubricants and packings.
Note
When replacing the fluid tip or fluid needle, replace both at
the same time. Using worn parts can cause fluid leakage.
To prevent damage to the fluid tip (2) or fluid needle (7),
be sure to either:
• Pull the trigger and hold while tightening or loosening
the fluid tip, or
• Remove fluid needle adjusting knob (6) to relieve spring
pressure against needle collar.
Spray Gun Lubrication
Daily, apply a drop of SSL-10 spray gun lube at trigger bearing
stud and the stem of the air valve. The shank of the fluid needle
where it enters the packing nut should also be oiled. The fluid
needle packing (7) should be kept soft and pliable by periodic
lubrication. Make sure the baffle (4) and retaining ring (1) threads
are clean and free of foreign matter. Before assembling retaining
ring to baffle, clean the threads thoroughly, then add two drops
of SSL-10 spray gun lube to threads. The fluid needle spring (6)
and air valve spring (8) should be coated with a very light grease,
making sure that any excess grease will not clog the air passages.
For best results, lubricate daily.
