5. TowFLEXX Operation
5.1 Switching the aircraft tug on and off
In general, the aircraft tug is de-energized via both battery disconnect switches. In addition, to
protect against unauthorized access, a key switch is installed. Before starting the unit via key
switch, make sure both e-Stops are pulled, otherwise no current is owing.
Switch on:
1. Turn the key switch to the ON (2) position and then
overturn it to position 3 to start the ignition.
2. Pull both battery disconnect switches (e-Stops)
Turn off:
ATTENTION! If the battery disconnect switch (e-Stop) is activated while
driving, the aircraft tug is braked to maximum standstill with maximum
braking force. There is an increased risk of accidents, damages and injuries.
• Do not use the battery disconnect switches (e-Stop) as a service brake, ONLY in
an emergency situation.
ATTENTION! Due to a defective or inaccessible battery disconnect switch
(e-Stop), there is a risk of accident. In dangerous situations, the operator cannot
stop the aircraft tug in time by operating the battery disconnect switch (e-Stop).
• The function of the battery disconnect switch (e-Stop) must not be
aected by objects.
• Immediately notify the supervisor of any detected defects on the battery
disconnect switch (e-Stop)
• Mark and shut down the defective aircraft tug.
• Only put the aircraft tug back into service after locating and repairing
the defect.
ATTENTION! If the tug is not being used, make sure that the key switch is tur-
ned to the OFF position. Otherwise there is a risk that the batteries will be fully
discharged and thus irreparably damaged.
