Important
Do not use halogenated hydrocarbons in coating application
equipment where aluminium or galvanized parts come
in contact with the solvent or coating material.
Halogenated hydrocarbons e.g. 1,1,1-thrichloroethane and
methylene chloride react, violently with such parts, causing
corrosion and danger for explosion.

The high velocity flow of air and liquids through hoses and
nozzles may develop static electricity. Be sure that the equ-
ipment, object being sprayed, spraybooth, paint and waste
container are properly grounded to prevent static discharge
or sparks.

Operation
•Install and operate the spray gun according to Fig.1, 2, 3 and 3.
•Blow the paint and air hoses clean before connection.
•Check that all connections are tight .
•Keep the spray gun clean and lubricate (waterfree vaseline)
moving parts at regular intervals.
•Lubricants for surface-treatment equipment must not contain
silicon.
• For short standstill periods, for instance over a night, it will
suffice to clean the air and paint nozzles on the outside. If a
two-component paint is used, however, the gun must be flushed
through immediately with solvent. This must also be done if the
gun is to remain unused for a longer period of time.
•When cleaning the air cap and the paint nozzle, use a soft
brush dipped in clean solvent. Do not place the entire gun in
solvent, as the oil on the lubricated parts would be dissolved. Blow
the air cap dry with comressed air from both sides.
•Never use iron or steel wire to clean air holes and ducts in
the nozzles.
•When assessing the reaction time of the connected spray
gun (the time from the start impulse until spraying commen-
ces) the reaction time of the control valve must be taken into
consideration.
• Rec om mend size for control valve:
– Control valve, 3-way, G 1/4. Min. flow area 28 mm2.
Mechanically, pneumatically or electrically actuated.
As the equipment works under pressure the utmost care must
be observed during the work. Bearing this in mind, never aim
the spray gun at a person or towards any part of the body. In
the event of personal injury caused by the spraying pressure,
immediate medical attention is essential. Before carrying out
any adjustment or repair, the equipment must be switched off
and the paint pressure relieved.
WARNING
How to operate
Note:
Valve orifice inside three-way solenoid valve should be minimum
ø 4 mm and also operating air hose length should be within 10 m
with the inner diameter more than ø 6 mm to avoid delayed
operation and any kind of failure.
Recommended paint viscosity differs according to paint properties
and painting conditions. 15 to 23 sec./Ford cup 4 is recommendable.
The gun is operate at low air pressure, high transfer efficiency will not
be obtained if the spray distance is to far.
Set the spray distance from the gun to the work piece as near as possible
within the range of 150-300 mm.
Paint spraying
Inhalation of paint, paint dust and solvent is not healthy. Make
sure an approved spraybooth is used. The operator must use
personal protection-breathing mask or fresh air hood.

Air caps (See Fig. 5 and 6)
The air caps are tested and certified according to the SEAVA meth-
od. This gives a ”finger print” of the spray pattern on each air cap.
For further information please contact your supplier.
The retaining ring for the air cap shall only be tightened with hand force.
No tools are required. Especially important when a cap cleaner is used.
Fix 2 on the air cap, denotes that the air cap can be installed in ver-
tical or horizontal position, depending on the position of the pin in the
distribution ring (See Fig. 5 and 6).
Fix 4 on the air cap, denotes that the air cap can be installed in ver-
tical or horizontal position, regardless off the position of the pin in the
distribution ring.
Air caps can be sent back for checking and comparity the
performance. For further interesting please contact your supplier.

VARNING
Before reassembling the different components:
• Clean the parts with the appropriate cleaning agent by means
of brush.
• Install new seals after having lubricated them with PTFE grease.
• Install new parts if necessary.
Troubleshooting
Introduction
Always commence troubleshooting by checking the general condition
of the spray gun. This can most easily be determined by test spraying,
which provides an opportunity for checking the spray pattern and capacity,
air leakage and gasket leakage.
Types of problems
Collection of information which makes it possible to identify the error
symptoms applicable to the spray gun in the event of malfunctioning
is a matter of vital importance. Identification of symptoms makes it possible
to decide whether the spray gun itself is the direct cause of the malfunc-
tioning or if this may have been caused by an external factor.
The following external factors can cause malfunctioning and should be
thoroughly checked:
1. The quality of the air, i.e. content of moisture, dirt particles and oil.
2. The quality of the paint, i.e. its viscosity, purity. etc.
3 The air and paint pressure in relation to viscosity of the paint and
nozzle combination used.
4. The size of the air/paint hoses.
Troubleshooting chart (See page 8)
Distribution ring
1. Remove the air cap (23) and the paint nozzle (22).
2. Remove the distribution ring (20) by screwing on the air cap (23) a
few turns. Withdraw the distribution ring axially from the body (13).
3. Re-fit the distribution ring (20) by mating it with a guide pin in
the body (13).
4. Re-fit the paint nozzle (22) (with torque 30 Nm) and re-fit the air cap
(23) (tighten by hand).

a) Dried paint on holes for atomizing air.
Clean the air holes, use appropriate clean-
ing agent and a soft brush.
b) Damage to holes for atomizing air.
Replace the air cap with a new one.
c) Air cap not sufficiently tightened.
Tighten the air cap properly by hand.
