WALTHER PILOT PILOT I, Operating Instruction

Page: 12 / 24

3 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
flammable 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 (eart-
hed) by means of a conductive air hose (maximum resistance 10
6
Ω ).
• 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 brea-
thing 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. 72 dB (A).
• 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.

4 Connection of input lines
Warning
Material and air hoses which are installed with a hose grommet must be additonally
secured with a hose clamp.
Gravity-Feed 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. 22).
2. Fill the gravity-feed cup with screened material and close the gravity-feed cup.
3. Switch on the pneumatic system. The spray gun can then be taken into operation.
5 Operational Handling
The following requirements must be met before the spray gun can be put into opera-
tion:
The air pressure must not exceed 8 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 72 dB(A).
• 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!
6 Adjusting the spray pattern
The spray pattern of the PILOT I can be changed by adjusting the gun as follows:
Setting the material flow
rate:
The material output depends
on the size of the nozzle
installed - and may also be
controlled by way of adjusting
the set-screw (Item 18).
Setting the spray jet:
The spray jet is adjusted by
way of turning the air cap
(Item 1) forward or back as
required (this does not apply to
the flat-jet air cap). Once the
desired spray jet ratio has
been obtained, use the adju-
sting collar (Item 2) to lock the
air cap in position.

Adjusting the atomising
air low rate:
The atomising air flow rate can
be adjusted by the air pressure
reducing valve in the plant.
