7.1 General Information
Repairs or overhauls may only be carried out by personnel trained and certied by TowFLEXX.
In order to ensure reliable operation of the aircraft tug use only certied and original parts from
the manufacturer. Neglecting to do so will void the warranty.
7.2 Requirements for the storage room
If the aircraft tug shut down for more than a month, storage is only allowed in a frost-free and
dry environment. Perform actions before, during and after the decommissioning as described.
7.3 Actions before and during Shut down
• Clean the aircraft tug carefully
• Apply a light oil on all non-painted or galvanised parts, or cover them with a greasy lm
• Charge Batteries (see 4.8 Aircraft Tug Charger; Page 30).

7.4 Required Actions during Decommissioning
7.5 Re-commissioning the Aircraft Tug

happen. Deep-discharges shorten the lifespan of the batteries substantially. To
prevent a deep-discharge, recharge the batteries at least once a month.
