Towbar coming loose!
If the towbar is not correctly locked into the coupling of the CHALLENGER550, the towbar can
become loose. The loose, swinging end of the towbar can hit persons.
The loose, swinging end of the towbar can kill or seriously injure persons.
Before operating the "Maintenance-towing/Repositioning" modes, make sure that the towbar
is correctly secured to the coupling with the bolt.
The preparations have now been made for "Maintenance-towing" or "Repositioning" mode.
Rolling CHALLENGER550!
The CHALLENGER550 can run over persons when starting to drive.
Running over persons can result in death or serious injuries.
Ensure that no persons are located between CHALLENGER550 and towbar.
Ensure that visual and radio contact is always maintained with the wing walker.
Jerky movements when starting! Sudden steering movements!
The aircraft nose gear can be damaged or the "shear pin" on the towbar broken because of jerky
driving and sudden steering movements.
Drive continuously and slowly.
Select the correct drive position in order to avoid too great a torque.
Steer continuously and avoid abrupt and non-constant steering movements.
Brake the train (CHALLENGER550-towbar-aircraft) in a continuous straight line.
Maintain constant visual and radio contact with the wing walker.
Maintain constant radio contact with the aircraft's pilot.
INFORMATION
The maximum speed for the driving mode "Maintenance-towing" or "Repositioning" is the responsi-
bility of, and must be determined by, the operator.
