10.5. 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.
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.
11. Maintenance and repairs
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 15).
11.1. Replace the quick coupling
Notice!
The quick coupling is fixed on the mixing cap with Loctite. This can be
heated with a hot-air blower to make it easier to loosen the quick cou-
pling.
Remove the quick coupling
■ Unscrew the quick coupling [2-4] from the mixing cap [2-5] while hold-
ing the mixing cap in place.
Mount new quick coupling
■ Coat the quick coupling [2-4] with Loctite 276.
