8. Start-up
•Assemble the aircap on the gun by positioning it according to the desired spray
orientation.
•Open at the maximum the air needles.
•Open the fluid needle as far as i twill go without a stop.
•Connect the air hose.
•Assemble the cup.
•Pull the trigger and check that the air is circulating normally.
9. Adjustments
This professional spray gun features 3 controls :
Spraying fineness
•Air is fed by the central air. The air is adjusted by means of the air regulator
mounted upstream of the gun on the network and more precisely by means of
the knob at the bottom of the gun handle on some manual guns.
Fan width
•Fan width is adjusted by using the knurled knob. It controls the air going to the
horns on the aircap. In this way, the air is controlled through the fanned air outlets
and allows the fan to change from flat (wide open) to round (closed).
Fluid output
•Having selected the proper fluid nozzle / needle assembly and the fluid pressure,
it is possible to:
•Further control the output by changing the travel of the needle (using the needle
stop knob).
•Optimal set up is usually obtained when the fluid needle is completely open.
When this needle is nearly closed, a constant flow of fluid cannot be
guaranteed.

14
10. Gun handling
When assembling the aircap on the gun, hold it vertically in order to correctly align the
aircap before screwing the aircap ring.
Proper position
Improper position
•Keep the gun perpendicular to the surface to be painted.
•Avoid working with the wrist.
•Do not forget that crossed sweeps cannot correct irregularities. Spraying from a
stationary gun will not give you even coverage.
•Start the pass and trigger just before the leading edge. Release the trigger
before the pass ends, just after the trailing edge of the object.
•Make sure that overlapping from the passes is even.

15
11. Maintenance
11.1 Preventive maintenance
Daily
•Check groundings.
•Clean the outside of the spray nozzle with a soft brush and solvent.
•Flush the spray gun.
•When the spraying system will not be used for an extended period of time, take
off the nozzle and immerse it in s solvent filled container.
Weekly
•Check leakage from the fittings
Monthly
•Check hoses.
•Operate the valves.
•Remove the air valve, clean it if necessary. Grease it as well as the spring before
assembling.
•Remove the needle as well as the rear line and the complete air valve.
•Clean the parts and grease them before assembling.
Annual
•Change the air valve. Grease the air valve as well as the spring, before
assembling.
•Remove the gun.
•Clean the parts.
•Change the seals and any defective parts.
•Grease them before assembling (refer to seal and servicing kits).
Note: Frequencies are given as an estimate. They must be adapted by the
maintenance service of the user for every installation depending on the fluid, the
workload and the working pressure.
12. Assembly - Disassembly
Before removing a component of the gun, some precautions have to be taken:
•Shut off the fluid pressure,
•Empty out the paint inside the cup or the receiver and clean it,
•Fill the cup or the receiver with cleaning solvent,
•Take off the gun spraying air cap,
•Shut off the gun supply air pressure,
•Adjust fluid pressure to 0.5 bar / 7.25 psi and let the solvent circulate,
•Shut off the fluid pressure,
•Remove the part to be cleaned or changed.
Note: Do not remove the baffle (3) as this may damage the gun body.

16
Before reassembling the different components, some precautions must be taken:
•Clean all the parts with the appropriate cleaning solvent and a brush.
•Install new seals if it is necessary after having lubricated them with PTFE grease.
•Install new parts if it is necessary.
13. Assembly errors
The use of improper replacement or defective parts may result in hazards to personnel,
damage, malfunction or general shutdown of the equipment.
14. Troubleshooting
Distorted
spray
Slightly unscrew the aircap retaining ring and rotate the
aircap by one half turn. If the defect is reversed, one of the
lateral air holes is plugged up or deformed. Clean the gun
aircap with solvent and unclog the air holes with
compressed air. If the problem is not resolved, it means that
the fluid nozzle is damaged.
Displaced
spray
This comes from a defect in the central fan. Clean the
aircap and the fluid nozzle. Make sure that:
•the aircap is correctly centered on the nozzle,
•the nozzle is not too big for the needle,
•when work is done with a large needle opening and the
needle almost closed, the spray pattern is not even in all
directions.
Fragmented
pattern
The fan air pressure is too high at the holes in the air cap
horns:
•turn the fan air co
ntrol clockwise to reduce the fan air
pressure,
•increase the paint output.
Fan too thick
in the center
This is the reverse of the above defect:
•the paint output is too high for the selected air pressure :
•increase the spraying air pressure and reduce
the paint
output.
•if the paint is too thick, dilute it.
Intermittent
spray pattern
An air inlet in the paint circuit creates an intermittent
pattern when:
•the paint cup is nearly empty,
•when the nozzle is not tightened on its seat: clamp it.
If the problem persists, remove the nozzle and clean it.
•
Check that the seat and the cone are not damaged,
remove the nozzle and clamp it.
•Check that: the cup cover air hole is not blocked and the
paint is homogeneous and fluid enough (use the viscosity
cup).

17
Trouble Cause Solution
No fluid out of the gun •Clogged nozzle
•Cut the pressure on
the pump.
Depressurize the hoses.
•Remove and clean
the nozzle with solvent
by means of the brush.
•Check the seal
condition.
Pattern width narrows
during reversing phase of
the pump
•Air trapped in the fluid
circuit
•Check connections
and suction hose
quality.
•Viscosity too high
•Reduce viscosity.
Aircap becomes dirty
frequently
•Too much atomizing
air
•Reduce air pressure.
Fluid seeping from the air
holes of the aircap
•Defective nozzle seal
•Replace it.
•Nozzle loose
•Tighten it.
Fluid leak at the packing •Packing is worn
•Tighten up the packing
holder without
blocking the needle.
•If there is still a leak,
replace the packing
and the needle.
Fluid leak at the front part
of the gun, trigger released
•Impurities in the paint •Trigger the gun 3 or 4
times.
•Needle worn or/and
nozzle worn
•Replace needle
or/and nozzle.
Air leak at the valve •Valve worn •Change the valve.
Permanent air leak at the
gun aircap when the
trigger is released
•Friction on the needle •Remove the trigger
and check that the
needle slides freely.
•Valve worn •Replace the valve.
