Before operation
Screwing in the protective plug
▶ Screw the protective plug (1) back into the thread:
The protective plug must always be inserted when the cartridge is
not inserted.
Checking the operating pressure
▶ Check the operating pressure on the pressure indicator (1):
• If the pointer is in the green range, there is sufficient pressure
present.
• If the pointer is in the red range, the pressure is not sufficient and
the fastener driving tool must be refilled.
Excessive pressure in the compression chamber is diverted in
the tool by a safety valve.
