5.6.1. SAFETY VALVE
The sandblaster is fitted as standard with a safety valve
[Spare parts 1
– Posit.10]
installed
on the top of the tank
[Spare parts 1
– Posit.2]
, in order to never exceed the maximum working
pressure for which it has been designed (6 kg/cm
2
). If it exceeds the safety pressure, the valve
will unload the pressure excess.
No manipulation in safety valve or its seal may be done. Any valve alteration can
cause serious damages to user and alter the correct functioning of the equipment.

placed in
the inside of the regulation box
[Spare parts 1

has been designed so that with no piloting signal (gun trigger
