Warning
Material and air hoses which are installed with a hose grommet must be additonally
secured with a hose clamp.
Design: Gravity-Feed Cup, Suction Cup and Suspended Pressure Cup
1. Connect the air hose to the air pipe (cleaned compressed air) or on an air cleaner
and on the air inlet of the spray gun (pos. 29).
2. Fill the cup with screened material.
3. Close the gravity-feed cup or suspended pressure cup. Switch on the pneumatic
system. The spray gun can then be taken into operation.
Design: Material Inlet
1. Connect the air hose to the air reduction valve (cleaned compressed air) - or an air
cleaner - and to the air inlet of the spray gun (pos. 29).
2. Fasten the material inlet hose to the material pressure tank or to the material pres-
sure control of a pump system and to the material inlet of the spray gun (pos. 41).
3. Fill the material pressure tank with material and close the lid.
4. Set the desired material pressure at the air pressure reduction valve; if the material
is supplied via pump systems, the material pressure is adjusted via the adjustment
wrench at the material pressure control.
5. Open the material tap at the pressure tank.
6. To let escape the air contained in the material hose, actuate the trigger (pos. 31)
until a uniform jet emerges from the nozzle; the spray gun can then be closed
again. The spray gun can then be taken into operation.

Operational Handling
The following requirements must be met before the spray gun can be put into operation:
The material pressure must not exceed 8 bar. The air pressure must not exceed 8 bar.
For spray guns with a suspended pressure cup, the material pressure shall not exceed
3
bar.
1. Before using the gun, first carry out a spray pattern test. The spray pattern can
best be tested on a sample workpiece or on a sheet of metal, cardboard or paper.
2. Check the spray pattern sample and, if necessary, adjust the settings of the spray
gun.
Pay attention to the following safety warnings when using the spray gun!
• Always wear proper respiratory protection masks and protective overalls when using
the spray gun. Airborne particles can damage your health!
• Always wear suitable hearing protectors in the vicinity of the spray gun. These spray
guns produce sound levels of approximately 85 dB(A) (PILOT Maxi-HD) or 83 dB(A)
PILOT Maxi-MD and PILOT Maxi-ND).
• Ensure that the working area is absolutely free from open fires and naked lights –
and that smoking is strictly prohibited. The spraying of flammable liquids (e.g.
paint, adhesives) is always accompanied by the risk of fire and explosion.
• When spraying materials, keep hands and other parts of the body away from the
nozzle of the gun when it is under pressure. Risk of injury!
• Relieve the spray gun of all pressures when work is complete. Lines left in a
pressurised condition might burst and their contents are likely to injure persons
standing nearby!

Adjusting the Spray Pattern
The spray pattern of the PILOT Maxi can be changed by adjusting the gun as fol-
lows:
Adjusting the Material Pressure
Pressure-Feed Cup Version:
The material pressure can be adjusted with a screwdriver at the restriction valve.
Material Connection Version:
The material pressure can be adjusted only at the controls of the pumping system
or at the material pressure tank. Please observe the operating instructions and
safety warnings issued by the manufacturers concerned.

Air connection
Setting a wide or round jet:
The adjusting screw is used to adjust the width of the spray jet.
The jet can be changed to a wide jet by turning the screw anti-
clockwise (screwing out) and to a round jet by turning the screw
clockwise (screwing in).
Adjusting the atomising air flow rate
The atomising air flow rate can be adjusted by screwing the adju-
sting screw in or out.
Setting the material flow rate:
The material flow rate can be adjusted by screwing the adjusting
screw in or out. The flow rate is increased by turning the screw
anti-clockwise (screwing out) and decreased by turning the screw
clockwise (screwing in).
