Repairs may only be carried out by trained personnel. Only original spare parts approved by the
manufacturer must be used to ensure safe and reliable operation.
7.2 Requirements for Storage
If the aircraft tug is taken out of service for more than one month, it may only be stored in a
frost-free and dry room. Carry out the following actions before, during and after decommissio-
ning.
7.3 Actions prior to decomissioning
- Clean aircraft tug carefully
- Apply a thin layer of oil or grease to all mechanical parts that are not
painted or galvanized.

7.4 Required Actions during Decomissioning
7.5 Taking the aircraft tug back into service
• Clean aircraft tug carefully
• Charge the batteries
• Carry out maintenance according to plan
Note: Self-discharge of the batteries can cause deep discharge. Deep dis-
charging shortens the life of the battery considerably, or destroys them
completely. The batteries should be charged at least once a month.
WARNING! Any modication to the aircraft tug - especially to the safety equip-
ment - is prohibited.
