2.0 SAFETY INFORMATION
2.1 GENERAL
The Tronair Model 01-1109-0010 Snap-Bak Towbar is designed for moving Beech King Air, Queen Air, SJ30-2, and Starship
Aircraft only.
To ensure safe operation, please read the following statements and understand their meaning. This manual contains safety
precautions which are explained as follows. Please read carefully.
WARNING! is used to indicate the presence of a hazard that can cause severe personal injury, death, and/or
substantial property damage if the Warning Notice is ignored.
CAUTION! is used to indicate the presence of a hazard which will or can cause minor personal injury or property
damage is the Caution Notice is ignored.
WARNING!
A damaged or bent towbar should not be used. Towbar should be repaired or replaced.
WARNING!
Tronair recommends the use of a towbar with a category 1 or category 2 tug and aircraft not exceeding
75,000 lbs gross weight. Using the towbar with aircraft weighing in excess of this specific limitation may
result in excessive loads and stresses being applied to the towbar and/or the aircraft. These excessive
loads may cause failure of the towbar which could cause damage (INCLUDING WITHOUT LIMITATION to
the aircraft) and/or personal injury OR DEATH. TRONAIR MAKES NO REPRESENTATION, WARRANTY OR
GUARANTEE AS TO SUCH MISUSE AND DISCLAIMS ANY AND ALL LIABILITY FOR INJURY, LOSS OR
DAMAGE ARISING FROM OR RELATING TO SUCH MISUSE.

3.0 OPERATION
3.1 PRELIMINARY CHECKLIST
3.1.1 Towbar
Check weld between lunette and tube for cracks.
Check lunette for bending, excessive wear and deformity.
Check weld between tube and spring retainer for cracks.
3.1.2 Towing Head
Check welds between side rails and head rail for cracks
Check welds between head rail and spring retainer housing for cracks.
Check welds between side rails and stationary pin. Also sliding pin wear sleeve for cracks.
Check fastener connection of towing head to towbar. Ensure the connection is not loose or missing.
Check sliding pin ball lok-T pin. Ensure ball lok-T pin is securely attached to the side rail via its lanyard. Ensure ball lok-T
pin is not missing.
Check sliding pin for bending or excessive wear. Ensure sliding pin slides freely.
Check sliding pin roll pin. Ensure roll pin is not loose or missing.
Check snap-bak spring. Ensure the spring is not loose or taken a set. Ensure the spring operates correctly.
3.2 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 sliding pin is locked in place using the ball lok-T pin.
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. Reference Figure 3.
3.2.3 Couplers continued on following page.

King/Queen Air - Snap-Bak Towbar
03/2008 | Rev. 06 Page | 3
3.2.3 Couplers (continued)
Tronair recommends a telecoupler pintle hook arrangement. This arrangement is known to eliminate binding. Tronair offers a
Standard Telecoupler, Model Number 01-1950-5000, for use on tugs. Reference Figure 4.
Damage to the towbar and/or aircraft can result by towing or pushing an aircraft with an incorrect size eyebolt or pintle pin. A
correct size eyebolt will make contact with the pintle pin. A gap between the eyebolt outside diameter and the coupler face
plate should be easily seen. An eyebolt which is too large will cause the eyebolt to make contact with the face plate of the
coupler. When the eyebolt is too large for the coupler, a gap between the inside diameter of the eyebolt and the coupler face
plate will be seen. Reference Figure 5.
To ensure proper towing and pushing, check to make sure the pintle pin diameter is not too long for the eyebolt's inside
diameter. An approximate one-half inch (1/2") gap between the pin diameter and the eyebolt should be seen. If any of these
conditions are not met, please contact Tronair for information to obtain a new coupler.
3.2.4 Set Sliding Pin
Set the sliding pin to the correct location for aircraft using ball lok-T pin as shown in Figures 6  8.

3.2.4 Set Sliding Pin (continued)
3.2.5 Towing Operation
Damage to the towbar or aircraft can result from pushing an aircraft while maintaining too sharp of an angle between the tug
and the aircraft. Contact between the towbar weldment and the tug must be avoided. It is recommended that the angle
between the tug and towbar not exceed 90º. Reference Figure 9.
4.0 TRAINING
4.1 TRAINING REQUIREMENTS
The employer of the operator is responsible for providing a training program sufficient for the safe operation of the towbar.
4.2 TRAINING PROGRAM
The employer provided operator training program should cover safety procedures concerning use of the towbar in and around
the aircraft at the servicing location.
4.3 OPERATOR TRAINING
The operator training should provide the required training for safe operation of the towbar.
NOTE: Maintenance and Trouble Shooting are to be performed by the skilled and trained technician.
