Turn on the air tap 1.
Pull up regulator 2 and turn it until an air pressure of 6 bar is displayed on gauge 3.
Pull out regulator 4 and turn it until the hot air pressure on gauge 5 is at least 0.3 bar.
Turn the main switch 6 to position "I".
The hot air pressure must not fall below 0.2 bar!
If the hot air pressure is too low, there is a risk of the heating element fusing.
For this reason the heating is switched off automatically if the hot air pressure
is too low.
The machine functions, such as e.g. tape threading etc., are not activated until
the large pedal has been operated (pedal setting "+1").
Press keys 7 and at the same time bring the large pedal into position "-1". The sealing
temperature is reduced.
Wait until the value shown on display 8 sinks below 50ºC.
Turn off air tap 1.
Turn the main switch 6 to position "0".
Before turning off the compressed air at air tap 1, wait until the sealing
temperature has sunk below 50ºC ! If this point is not observed, the heating
element can fuse!
