8Start-up
•Assemble the head on the gun by positioning it according to the desired
spray orientation.
•Open at the maximum the air needle.
•Open the fluid needle as far as it will go without a stop.
•Connect the air hose.
•Assemble the cup.
•Pull the trigger and check that the air is circulating normally.
9Adjustment
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.

13
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. Keep the gun perpendicular to the
surface to be painted. Avoid working with the wrist.
Proper position
•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.
Improper position

14
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 a 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 kit and servicing kit).
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.
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.

15
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
a
ircap 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 control 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).
•Check that the ‘pressure’ gun is not being used with a
‘suction’ cup.

16
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 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 tip seal •Replace it.
•Tip 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 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 the needle.
•Valve worn •Replace the valve.
