USAGE PROCEDURE
3.2.1
Aircraft Attachment
CAUTION!
It is recommended that your towbar be attached to the aircraft first, and then connected to the tug to avoid
possible aircraft damage.
Ensure the slide pin is locked in place using the detent ball plungers.
3.2.2
Tug Attachment
CAUTION!
Damage to the towbar or aircraft can result from an excessive towbar angle during towing operations.
Reference Figure 1.
Use a pintle height so that the towbar is as level as possible during towing. Also, the pintle hook height should prevent
contact of the towbar with the ground during towing.
3.2.3
Couplers
CAUTION!
Damage to the towbar or aircraft can result while towing with the following types of couplers:
Lift Head
Standard Duty Latch
Vertical Side Swing Latch
Swivel Hook
The couplers listed above are known to cause binding and
failure in the lunette eye. Indicators of binding are wear on
outside diameter of the eyebolt and indentation on the
inside diameter of the eyebolt.
