After the machine has been switched on, the top feed roller must be lowered
with the pedal setting "+1", before the functions of keys 1 and 3 can be
selected.
By pressing key 1 the "press" function is switched on or off. When the function is
switched on, diode 4 flashes slowly. This function is used for the subsequent bonding of
the sealing seam without the application of a new sealing tape.
If key 2 is pressed a choice is made between the "feed roller raised" (diode 4 is on) and
"feed roller lowered" (diode 4 is off) modes.
If key 3 is pressed, the "feed roller in reverse" mode is switched on or off. If a fault
occurs, diode 4 flashes quickly.
