The spray-jet adjuster (item 18) is used to control the spray jet ratio, i.e.
LH-turn (outwards) =
flat jet,
RH-turn (inwards) = round jet.
The air volume regulating control (item 17) is used to adjust the atomizing air input.

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 depressurised. 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!
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.
Exhaust air containing particles (overspray) must be kept away from the working
area and personnel. In spite of these measures, always wear the regulation brea-

thing masks and protective overalls when using the gun. Airborne particles represent
a serious health hazard!
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 Mini and Mini-K) or approx. 83 dB (A) (PILOT Mini-MP).
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.

Assembly
Note
Use the exploded view at the beginning of these operating instruction to perform the
operational steps described hereafter.
Warning
The air pressure at the gun shall not exceed 8 bar; otherwise a safe operation of the
spray gun cannot be ensured.
Warning
Material and air hoses which are installed with a hose grommet must be additionally
secured with a hose clamp.
Design version: gravity-feed cup
1.
Connect the pressure-air hose between the
air supply system (cleaned pressure-air = air
cleaner) and the gun air inlet reducer
(item 21).
2.
Fill the gravity-feed cup with sieved material
and install the cup cover.
3.
Turn the air supply on.
The gun is now ready for operation.
