tiple glue outlets are to be regularly
flushed out using water tap connector.
This is only available from us for

periodically. This is carried out quite
simply by filling it with clean water.

safety valve must open at the latest with 6 bar air pressure.
2. Clean safety holes on lid circumference whenever necessary.
