PROJECTILE HAZARD. You may be injured by venting liquids or
gases that are released under pressure, or flying debris.
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.
IT IS THE RESPONSIBILITY OF THE EMPLOYER TO PROVIDE THIS INFORMATION TO THE OPERATOR OF THE EQUIPMENT.
Read the following warnings before using this equipment.
EQUIPMENT MISUSE HAZARD. Equipment misuse can cause
the equipment to rupture, malfunction or start unexpectedly and
result in serious injury.
GLOVES. Must be worn when spraying or cleaning the
equipment.
OPERATOR TRAINING. All personnel must be trained before
operating finishing equipment.
LOCK OUT / TAG-OUT. Failure to de-energise, disconnect, lock out and tag-
out all power sources before performing equipment maintenance could cause
serious injury or death.
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.
NEVER MODIFY THE EQUIPMENT. Do not modify the
equipment unless the manufacturer provides written approval.
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.
KNOW WHERE AND HOW TO SHUT OFF THE EQUIPMENT
IN CASE OF AN EMERGENCY.
WEAR SAFETY GLASSES. Failure to wear safety glasses with
side shields could result in serious eye injury or blindness.
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.
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.
SOLVENTS AND COATING MATERIALS. Can be highly flammable or
combustible when sprayed. Always refer to the coating supplier's instructions
and safety sheets before using this equipment.
In this part sheet, the words WARNING, CAUTION and NOTE are used to emphasise important safety information as
follows:
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.
CAUTION
Hazards or unsafe practices which could result in
minor personal injury, product or property
damage.
NOTEWARNING
WARNING
Important installation, operation or maintenance
information.
Hazards or unsafe practices which could result in
severe personal injury, death or substantial
property damage.
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 electric
shock and other serious injury.
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.

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.

11. The recommended spray distance is 50-100mm.
10. Hold gun perpendicular to surface being sprayed. Arcing or tilting may result in uneven coating.
9. The pattern size can be reduced by turning spreader valve knob (54) clockwise.
8. If finish is too wet, reduce fluid flow by turning fluid adjusting knob (36) clockwise. If atomisation
is too coarse, increase air inlet pressure. If too fine, reduce inlet pressure.
The gun is not designed for use with highly corrosive and/or abrasive materials.
To avoid premature degradation of parts, DeVilbiss recommends the gun is washed in neutral
cleaning solution (pH 6 to 8).
If there is any doubt regarding the suitability of a specific material, contact your DeVilbiss Distributor
or DeVilbiss direct.
The gun is not designed to be cleaned within an ultrasonic bath.
7. Test spray. If the finish is too dry, reduce airflow by reducing air inlet pressure.
6. Turn fluid adjusting knob counter clockwise until first thread shows.
5. Adjust inlet air pressure if required.
4. Turn spreader valve adjusting knob (54) counter clockwise to fully open.
3. Turn fluid adjusting knob (36) clockwise to prevent fluid needle movement.
12. Spray edges first. Overlap each stroke a minimum of 75%. Move gun at a constant speed.
2. Mix coating material to Manufacturer's instructions and strain material.
1. Connect the gun to a clean, moisture and oil free air supply using a conductive hose of at least
8mm I.D.
13. Always turn off air supply and relieve pressure when gun is not in use.
START-UP SEQUENCE
IMPORTANT: This spraygun is suitable for use with both waterbased and solvent based coating
materials.
CAUTION
SB-E-2-984 R1.0 10/24
EN
To clean air cap and fluid tip, brush exterior with a stiff bristle brush. If necesarry 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.
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.
NOTE
SPRAY GUN MAINTENANCE & CLEANING
If quick connect couplings are required, use only high flow quick connects. Other types will not flow
enough air for correct gun operation.
NOTE
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
necesarry to atomise the material being applied. Excess pressure will create additional overspray and
reduce transfer efficiency.
SB-E-2-984 R1.0 11/24

When removing air cap from retaining ring, do not remove slip ring or retaining ring seal from
retaining ring. Damage to the parts may occur.
The slip ring and retaining ring seal are not available as replacement parts.
Simply wipe parts clean and reassemble with new or clean air cap.
SPRAY GUN DISASSEMBLY / ASSEMBLY
KEY
Order for disassembly
When replacing the fluid tip or fluid needle, replace tip, needle and fluid packing at the same time.
Using worn parts can cause fluid leakage. Do not overtighten.
