dependent on the diameter of the nozzle and the adjustment of the material pressure
at the pressure tank or material pressure regulator. In addition, the material flow rate
can be controlled by screwing the adjusting screw in or out. For further adjustment
possibilities, see Section 6 "Changing the Spray Pattern".

Safety instructions

3.1

Identification of safety instructions

Warning
The pictogram and the urgency level "Warning" identify a possible danger to persons.
Possible consequences: Slight to severe injuries.
Attention
The pictogram and the urgency level "Attention" identify a possible danger to mate-
rial assets. Possible consequences: Damage to material assets.
Note
The pictogram and the urgency level "Note" identify additional information for the safe
and efficient operation of the spray gun.

General safety instructions

All applicable accident prevention rules and regulations as well as other recognised
industrial safety and health rules and regulations must be observed at all times.
Use the spray gun only in well-ventilated rooms. Fire, naked flames and smoking are
strictly prohibited within the working area. WARNING – during the spraying of flam-
mable materials (e.g. lacquers, adhesives, cleaning agents, etc.), there is an
increased risk to health as well as an increased risk of explosion and fire.
Measures must be taken to ensure that the spray gun is sufficiently grounded
(earthed) by means of a conductive air hose (maximum resistance 10
Before carrying out maintenance or servicing work, always ensure that the air and
material feed to the spray gun have been de-pressurised. Risk of injury!
When spraying materials, do not place your hands or other parts of the body in front
of the pressurised nozzle or the spray gun. Risk of injury!
Never point the spray gun at persons or animals. Risk of injury!
Exhaust air containing particles (overspray) must be kept away from the working area
and personnel. In spite of these measures, always wear the regulation breathing
masks and protective overalls when using the gun. Airborne particles represent a
serious health hazard!
Always observe the spraying and safety instructions given by the manufacturers of
the spraying material and the cleaning agent. Aggressive and corrosive materials in
particular can be harmful to health. Always wear hearing protection when using the gun
or when in the vicinity of a gun that is in use. The noise level generated by the spray
gun is approx. 85 dB (A) (PILOT Maxi) or approx. 83 dB (A) (PILOT Maxi-MP/HVLP).
After carrying out assembly or maintenance work, always ensure that all nuts, bolts

and screw connections have been fully tightened before the gun is used. Use only
original replacement parts, since WALTHER can only guarantee safe and fault-free
operation for original parts.

Connection of Input Lines

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
pressure 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.
