3.2
General Applicable Safety Precautions
All applicable accident prevention rules and regulations as well as other
recognized industrial safety and health rules and regulations must be observed
at all times
Use the spray gun only in well-ventilated rooms. Fires, naked light and smoking are
strictly prohibited in 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.
An adequate grounding of the extrusion gun is to ensure, for example, through the
fluid hose (maximum resistance 106Ω).
Before carrying out any maintenence or service work, always ensure that the air and
material feed to the spray gun have been de-pressurized. The extremely high pressure
at the gun or pump outlet can cause serious injury.Risk of injury!
When spraying make sure your hands and other body parts are clear from the
pressurized nozzle of the extrusion gun - the extremely high injection pressure can
cause serious injury.
Use diaphragm or piston pumps only in the context of a fluid regulator to prevent the
maximum allowable operating pressure of 350 bar can not be exceeded.
Do not point the extrusion gun towards people 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 presonnel. 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!
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 canonly guarantee safe and
fault-free operation for original parts.

materials, please contact WALTHER Spritz- und Lackiersysteme GmbH, D-42327

Assembly
Warning
Material lines that are attached with a hose must additionally be secured by a
hose clamp.
Warning
Risk of Injection. Spray from the dispensing valve, leaks, or ruptured components can
inject material into the body and cause serious injury, including the need for
amputation.
•
Although material injected into the skin may look like an ordinary injury, these are
extremely serious injuries. If injection occurs, get immediate medical attention.
•
Nozzle valve should never be pointed at people of body parts
•
Do not put your hands or fingers over the nozzle valve.
•
Never use the Extrusion gun without the trigger guard.
•
Before each use, make sure that the gun trigger safely operates the valve.
•
Always lock the trigger safety valve when not in use.
•
Before performing any cleaning, checking or servicing the equipment or clogged
valve nozzle following the steps given in 5.2 Starting and shutting down.
•
All fluid connections must be checked and tightened before start-up.
•
Inspect hoses, tubes, and couplings daily. Replace worn, damaged, or loose
parts immediately. Damaged hoses should not be repaired. In this case, the
entire hose should be replaced.
4.1
Supply Line Connection
Warning
Use the pump only in the context of a fluid regulator to prevent the maximum
allowable operating pressure of 350 bar can not be exceeded.
Material connection:
Attach the supply line at the connection item 20 of the extrusion gun. Maintain a
tight screw.
Notice
Use only grounded fluid hoses with a maximum total length of 150 m in order to
ensure a continuous ground and they must be resilient enough for an operating
pressure of 350 bar. Check the electrical resistance of the fluid hoses at least once
a week. If the hose does not have a label, on which the maximum electrical
resistance is specified, the maximum resistance values
can be obtained from the
manufacturer. If the resistance exceeds the recommended limits, replace the hose
immediately concerned.
The gun is now ready for operation.
