Preparing the pressure equipment
If you use an unsuitable compressed air cartridge and if both safety
valves are defective, the pressure in this cartridge can exceed the
maximum admissible operating pressure of the pressure equipment.
In this case the pointer of the pressure gauge (6.) indicates an
operating pressure of more than 10 bar.
When the pointer of the pressure gauge (9.) on the fitting for the
compressed air cartridge is in the red zone of the scale, the pressure
in the compressed air cartridge is no longer sufficient to operate the
pressure equipment.
In this case replace the compressed air cartridge with a full
compressed air cartridge.
You can refill the compressed air cartridge using the PKT-
FILLMASTER 350 compressor, which is available as an
accessory. You can also purchase a full compressed air
cartridge in exchange for an empty cartridge from your dealer.

WARNING
Risk of explosion if the maximum operating
pressure is exceeded.
Immediately disconnect the compressed
air cartridge from the pressure equipment.
