7.6 Working on the Electronics
Work on the electrical system must only be carried out when it is de-energised. The con-
densers installed in the controller must be completely discharged. The condensers are com-
pletely discharged after approx. 10 minutes. Before starting the maintenance work on the
electrical system:
- Work on the electrical system may only be carried out by qualied personnel, trained in
electrical engineering.
- Before starting any work, take all precautions that are necessary to prevent an electrical
accident.
- Parking the aircraft tug safely
- Disconnect the battery plug
- Take o rings, metal bracelets, etc.
7.7 Tires
The quality of the tires inuences the stability and the handling of the aircraft tug. The
TF3 has two air-lled drive wheels which inuence the straight running of the tug. The air
pressure should be checked at regular intervals. If there is a deviation from the target value
of 9 bar per tire, this must be corrected immediately, to guarantee a smooth operation.
In case of uneven wear, the stability of the tractor and the braking distance is increased.
- When changing wheels, ensure that the tug is not on an incline or slope
- Always replace wheels in pairs
WARNING! There is an increased risk of accidents due to electric current! Local
and country-specic regulations must be followed!
Warning! There is a risk of accidents when using tires that do not comply with
the manufacturer‘s specications.
