In this part sheet, the words WARNING, CAUTION and NOTE are used to
emphasis important safety information as follows:
⚠ WARNING ⚠ CAUTION NOTE
Hazards or unsafe practices which could
result in severe personal injury, death or
substantial property damage.
Hazards or unsafe practices which could
result in minor personal injury, product or
property damage.
Important installation, operation or
maintenance information.
⚠ WARNING
Read the following warnings before using this equipment.
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.
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.
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 housekeeping of working areas.
EQUIPMENT MISUSE HAZARD. Equipment misuse
can cause the equipment to rupture, malfunction or
start unexpectedly and result in serious injury.
FIRE AND EXPLOSION HAZARD. Never use
1,1,1-Trichloroethane, Methylene Chloride, other
Halogenated Hydrocarbon solvents or fluids containing
such solvents in equipment with aluminum wetted
parts. Such use could result in a serious chemical
reaction, with the possibility of explosion. Consult your
fluid suppliers to ensure that the fluids being used are
compatible with aluminum parts.
GLOVES. Must be worn when spraying or cleaning
the equipment.
WEAR SAFETY GLASSES. Failure to wear safety
glasses with side shields could result in serious eye
injury or blindness.
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.
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.
LOCK OUT / TAG-OUT. Failure to de-energies,
disconnect, lock out and tag-out all power sources
before performing equipment maintenance could
cause serious injury or death.
PROJECTILE HAZARD. You may be injured by
venting liquids or gases that are released under
pressure or flying debris.
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.
PRESSURE RELIEF PROCEDURE. Always follow
the pressure relief procedure in the equipment
instruction manual.
KNOW WHERE AND HOW TO SHUT OFF THE
EQUIPMENT IN CASE OF AN EMERGENCY.
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.
OPERATOR TRAINING. All personnel must be
trained before operating finishing equipment.
IT IS THE RESPONSIBILITY OF THE EMPLOYER TO PROVIDE THIS INFORMATION TO THE OPERATOR OF THE EQUIPMENT.

1. Daily lubrication and cleaning are necessary to maintain the best condition of the gun.
2. To clean the gun body, wipe exterior with solvent or cleaning solution dampened cloth.
Do not immerse the gun in a solvent or cleaning solution as it may damage the gun or
cause painting problems.
3. After using the gun, remove the paint and then pass an appropriate solvent or cleaning
solution through the paint path to wash away any remaining paint.
4. Do not leave any solvent or cleaning solution in the paint path or paint cup. It may cause
corrosion or damage.
5. The AIR CAP (2) can be immersed in solvent and brushed down for cleaning. If orifices
are clogged, use a toothpick to remove obstruction. Never use a steel wire or hard
instrument. This will damage air cap and result in a distorted spray pattern.
6. The following portions should be lubricated regularly (➡ in Fig.2); Sliding points of
TRIGGER SET(14), PATTERN VALVE ASSY (8), CHEATAR VALVE ASSY (15),
NEEDLE ADJUST SCREW (12), AIR VALVE (9-4), and NEEDLE (3-2).
For lubrication, SSL-10 Gun Lube* is recommended. (*Sold separately, contains NO
silicones or petroleum distillates.)
Do not lubricate to any portion where not instructed.
7. When installing AIR CAP (2), make sure no foreign materials adhered on RETAINING
RING ASSY (1) and thread of body and then oil one drop of Gun Lube SSL-10. (⇒ in Fig.2)
8. Apply non-silicone grease lightly on NEEDLE SPRING (11) and AIR VALVE SPRING
(9-5). Do not apply too much grease as it may clog the air passage.
Before replacing gun parts, remove materials from the gun for cleaning. Then release the air pressure of the gun and remove all hoses
and paint containers. Perform the replacement work in a clean place and fix the gun properly. Use the appropriate tools indicated for
replacement of parts. After replacing the parts, operate the gun and check that the replaced parts are functioning properly.
FLUID TIP & NEEDLE SET (3)
1. Loosen completely PATTERN VALVE ASSY (8) knob by turning the knob counterclockwise.
2. Remove NEEDLE ADJUST SCREW (12) and NEEDLE SPRING (11) and then withdraw NEEDLE (3-2).
3. Remove RETAINING RING ASSY (1) and AIR CAP (2).
4. Remove FLUID TIP (3-1) by using 19mm wrench.
5. Clean the seal surface on the GUN BODY side and tighten a new FLUID TIP with a torque wrench (recommended tightening torque:
8N-m).
6. Insert a new NEEDLE and NEEDLE SPRING and install the NEEDLE ADJUST SCREW.
FLUID INLET (6), AIR CONNECTOR (16)
FLUID INLET SET (6) and AIR CONNECTOR (16) are fixed together by sealing material. Do not remove these parts if you do not need them,
as they may cause damage.
PATTERN VALVE ASSY (8), CHEATER VALVE ASSY (15)
Disassembling and reassembling PATTERN VALVE ASSY (8) and CHEATER VALVE ASSY (15) by using 13mm wrench. When disassembling
and reassembling, turn the knobs completely counterclockwise.
AIR SEALS & AIR VALVE SET (9)
1. Remove NEEDLE ADJUST SCREW (12) and NEEDLE SPRING (11) and then withdraw NEEDLE (3-2).
2. Remove AIR VALVE BUSHING (10) by using 14mm wrench.
3. Withdraw VALVE SPRING (9-5), AIR VALVE (9-4).
4. Withdraw VALVE SEAT (9-3). Be careful not to damage the seal surface on the GUN BODY side.
5. Remove LOCK SCREW (9-2) by using 7mm hex wrench. Be careful not to damage the seal surface on the GUN BODY side.
6. Push the AIR SEAL (9-1) toward the back of the GUN BODY to remove it.
7. Remove the AIR SEAL (9-6) inside the AIR VALVE BUSHING. Be careful not to damage the seal surface on the AIR VALVE BUSHING side.
Do not reuse the removed AIR SEALS & AIR VALVE SET.
8. Install the new AIR SEALS & AIR VALVE SET in the reverse procedure of removal, being careful not to damage it.
The separately sold AIR SEAL INSERTION TOOL (17) is convenient for inserting the AIR SEALS (9-1, 3, 6).
9. Install the NEEDLE, NEEDLE SPRING and NEEDLE ADJUST SCREW.
NEEDLE PACKING ASSY (13)
1. Remove NEEDLE ADJUST SCREW (12) and NEEDLE SPRING (11) and then withdraw NEEDLE (3-2).
2. Remove NEEDLE PACKING ASSY (13) by using 10mm wrench.
3. Install a new NEEDLE PACKING ASSY. Use a 10mm wrench to tighten it until it stops lightly first, and then tighten it about 1/16 turn.
4. Install the NEEDLE, NEEDLE SPRING and NEEDLE ADJUST SCREW.
