Improper Use; Technical Description; General Safety Instructions - WALTHER PILOT PILOT Maxi-HD Betriebsanleitung

This equipment complies with the explosion protection requirements of Directive 94 / 9
/ EC (ATEX 100a) for the explosion group, equipment category and temperature class
indicated on the type plate. When using the equipment, the requirements specified in
these Operating Instructions must be observed at all times.
The technical data indicated on the equipment rating plates and the specifications in
the chapter "Technical Data" must be complied with at all times and must not be
exceeded. An overloading of the equipment must be ruled out.The equipment may be
used in potentially explosive atmospheres only with the authorisation of the relevant
supervisory authority.
The relevant supervisory authority or the operator of the equipment are respon-
sible for determining the explosion hazard (zone classification).
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 PILOT 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

Improper use

The spray gun cannot be used for any application not included in the instructions. Any
other use is improper, e. g.:
• Spraying in direction of people or animals
• Spraying liquid nitrogen

When operating the trigger, the air valve (preliminary air) is opened first and then
the material needle (pos. 16) is pulled back. This allows the spraying material to
flow through the nozzle. Closing is performed in reverse order. 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 addition, the materi-
al flow rate can be controlled by screwing the adjusting screw in or out.For further
adjustment possibilities, see Section 6 "Changing the Spray Pattern".

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
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 repre-
sent 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-HD) or approx. 83 dB (A) (PILOT
Maxi-MD/ND).
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.
