GUN ONLY
The SRiPro Lite spray gun is a professional quality gun designed with both High Efficiency or high volume, low
pressure (HVLP) technology. HVLP technology reduces overspray and limits air cap pressure to 0.7 bar [10 psi],
(complies with rules issued by SCAQMD and other air quality authorities). High Efficiency technology, when
tested under recommended conditions, has been found to exceed 65% transfer efficiency.
IMPORTANT: This spraygun is suitable for use with both waterbased and solvent based coating materials. The
gun is not designed for use with highly corrosive and/or abrasive materials and if used with such materials it
must be expected that the need for cleaning and/or replacement of parts will be increased. If there is any doubt
regarding the suitability of a specific material, contact your DeVilbiss Distributor or DeVilbiss direct.

LOCK OUT / TAG-OUT. Failure to de-energise, disconnect, lock out and tagout all power sources before performing equipment maintenance could cause
serious injury or death.
In this part sheet, the words WARNING, CAUTION and NOTE are used to emphasise important safety information as
follows:
FIRE AND EXPLOSION HAZARD. Never use 1,1,1-Trichloroethane,
Methylene Chloride, other Halogenated Hydrocarbon solvents or fluids
containing such solvents in equipment with aluminium wetted parts. Such use
could result in a serious chemical reaction, with the posibility of explosion.
Consult your fluid suppliers to ensure that the fluids being used are compatible
with aluminium parts.
STATIC CHARGE. Fluid may develop a static charge that must be dissipated
through proper grounding of the equipment, objects to be sprayed and all other
electrically conductive objects in the dispensing area. Improper grounding or
sparks can cause a hazardous condition and result in fire, explosion or elecrtic
shock and other serious injury.
SOLVENTS AND COATING MATERIALS. Can be highly flammable or
combustible when sprayed. Always refer to the coating material supplier's
instructions and safety sheets before using this equipment.
READ THE MANUAL. Before operating finishing equipment, read and
understand all safety, operation and maintenance information provided in the
operation manual. Users must comply with all local and national codes of
practice and insurance company requirements governing ventilation, fire
precautions, operation and house-keeping of working areas.
EQUIPMENT MISUSE HAZARD. Equipment misuse can cause
the equipment to rupture, malfunction or start unexpectedly and
result in serious injury.
WARNING
CAUTION
Hazards or unsafe practices which could result in
minor personal injury, product or property
damage.
GLOVES. Must be worn when spraying or cleaning the
equipment.
Read the following warnings before using this equipment.
WARNING
WEAR SAFETY GLASSES. Failure to wear safety glasses with
side shields could result in serious eye injury or blindness.
WEAR RESPIRATOR. The use of respiratory protective
equipment is recommended at all times. The type of equipment
must be compatible with the material being sprayed.
NEVER MODIFY THE EQUIPMENT. Do not modify the
equipment unless the manufacturer provides written approval.
PRESSURE RELIEF PROCEDURE. Always follow the pressure
relief procedure in the equipment instruction manual.
TOXIC VAPOURS. When sprayed, certain materials may be poisonous, create
irritation, or are otherwise harmful to health. Always read all labels, safety
sheets and follow any recommendations for the material before spraying. If in
doubt contact your material supplier.
NOISE LEVELS. The A-weighted sound level of pumping and spray equipment
may exceed 85 dB(A) depending on equipment settings. Actual noise levels
are available on request. It is recommended that ear protection is worn at all
times while equipment is in use.
HIGH PRESSURE CONSIDERATION. High pressure can cause serious
injury. Relieve all pressure before servicing. Spray from the gun, hose leaks or
ruptured components can inject fluid into your body and cause extremely
serious injury.
Important installation, operation or maintenance
information.
INSPECT THE EQUIPMENT DAILY. Inspect the equipment for
worn or broken parts on a daily basis. Do not operate the
equipment if you are uncertain about its condition.
Hazards or unsafe practices which could result in
severe personal injury, death or substantial
property damage.
KNOW WHERE AND HOW TO SHUT OFF THE EQUIPMENT
IN CASE OF AN EMERGENCY.
OPERATOR TRAINING. All personnel must be trained before
operating finishing equipment.
PROJECTILE HAZARD. You may be injured by venting liquids or
gases that are released under pressure, or flying debris.
IT IS THE RESPONSIBILITY OF THE EMPLOYER TO PROVIDE THIS INFORMATION TO THE OPERATOR OF THE EQUIPMENT.

Mix coating material to Manufacturer's instructions and strain material.
START-UP SEQUENCE
Turn fluid adjusting knob (14) clockwise to prevent fluid needle movement.
1
Hold gun perpendicular to surface being sprayed. Arcing or tilting may result in uneven coating.
The recommended spray distance is 50-100mm.
2
345
Turn spreader valve adjusting knob (19) counter clockwise to fully open.
Adjust inlet air pressure if required.
Turn fluid adjusting knob counter clockwise until first thread shows.
Test spray. If the finish is too dry, reduce airflow by reducing air inlet pressure.
If finish is too wet, reduce fluid flow by turning fluid adjusting knob (14) clockwise. If
atomization is too coarse, increase air inlet pressure. If too fine, reduce inlet pressure.
The pattern size can be reduced by turning spreader valve knob (19) clockwise.

679
The spray gun must be earthed to dissipate any electrostatic charges which may be created by fluid
or air flows. This can be achieved through the spray gun mounting, or conductive air/fluid hoses.
Electrical bond from the spray gun to earth should be checked and a resistance of less than 10⁶ Ohms
is required.
WARNING
8
10
Connect the gun to a clean, moisture and oil free air supply using a conductive hose.
Spray edges first. Overlap each stroke a minimum of 75%. Move gun at a constant speed.
Always turn off air supply and relieve pressure when gun is not in use.

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 taken to prevent scratching or burring of the holes which will cause a distorted spray pattern.
Depending on hose length, larger I.D. hose may be required. Install an air gauge at the gun handle.
When gun is triggered on, adjust regulated pressure as required. Do not use more pressure than is
necessary to atomize the material being applied. Excess pressure will create additional overspray and
reduce transfer efficiency.
NOTE
If quick connect couplings are required, use only high flow quick connects. Other types will not flow
enough air for correct gun operation.
To clean fluid passages, remove excess material, then flush with gun wash solution. Wipe the gun
exterior with a dampened cloth. Never completely immerse in any solvent or cleaning solutions as
this is detrimental to the lubricants and life of the spray gun.

To prevent damage to fluid tip or fluid needle, be sure to either:
1.
NOTE
2.
Pull the trigger and hold while tightening or loosening the fluid tip, or,
Remove the fluid adjusting knob to relieve spring pressure against needle collar.
When replacing the fluid tip or fluid needle, replace tip, needle and fluid packing at the same time.

Remedies for the top-heavy, bottom-heavy, right-heavy and left-heavy patterns.
Determine if the obstruction is on the air cap or the fluid tip. Do this by making a test spray pattern. Then, rotate
the cap one-half turn and spray another pattern. If the defect is inverted, obstruction is on the air cap. Clean the
air cap as previously instructed. Also check for dried paint just inside the cap center hole opening, remove by
washing with solvent.
If the defect is not inverted, it is on the fluid tip. Clean tip. If problem persists, renew tip.
Material build-up on fluid tip exterior
or partially plugged fluid tip.
Replace fluid tip or air cap if
necessary.
Fluid tip or cap dirty or damaged.
