9.5. Safety valve

The pressurized cup spray gun is fitted with a safety valve, depending on
the version. This vents the pressurized cup spray gun from a pressure of
10.0 bar in the aluminium pressurized cup version or from a pressure of
8.0 bar in the plastic pressurized beaker version.
Warning!
Risk of injury from manipulated safety valve
A manipulated safety valve fails to vent the pressurized cup spray gun
properly and the pressurized cup can explode.
→ Any changes to the safety valve are prohibited and not allowed.

10. Maintenance and repairs

Warning!
Risk of injuries from components coming loose
Components may come loose unexpectedly when performing mainte-
nance to the pressurized cup spray gun while this is still connected to
the compressed air circuit.
→ Always disconnect the pressurized cup spray gun before all mainte-
nance work and vent it completely.
Spare parts are available for carrying out repairs (see chapter 14).

pling.
