The operator must check and ensure that all technical data and the marking of the
equipment in accordance with ATEX are compliant with the necessary requirements.
The operator must provide corresponding safety measures for all applications in
which the breakdown of the equipment might lead to danger to persons.
If any irregularities are observed while the equipment is in operation, the equipment
must be put out of operation immediately and WALTHER Spritz- und Lackiersysteme
must be consulted.
Grounding / Equipotential Bonding
Measures must be taken to ensure that the spray gun is sufficiently grounded
(earthed) by means of a conductive air hose (maximum resistance 10
6
Ω
).
1.3
Inappropriate use
The spray gun can’t be used for any application not included in the instructions. Any
other use is improper. Some sample of improper use:
•
Spray in direction of people or animals
•

2.2 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, 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
6
Ω
).
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. 83 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.

Technical Description
PILOT Trend:
Manual spray gun for conventional atomisation
Model version:
• with gravity-feed cup
• with material Connection
PILOT Trend-MP: Manual spray gun for medium pressure
Model version:
• with gravity-feed cup
• with material Connection
The spraying pressure is 1.2 to 1.4 bar with an input pressure of 3.0 to 3.3 bar
The material flow rate is dependent on the diameter of the nozzle and the adjustment
of the material pressure at the pressure tank or material pressure regulator. In addi-
tion, the material flow rate can be controlled by screwing the adjusting screw (N° 18)
in or out. For further adjustment possibilities, see Section
