Under normal usage and with minimal maintenance this towbar will provide exceptional service. WARNING! A damaged or bent towbar should not be used, but should be repaired or replaced. USING A DAMAGED OR BENT TOWBAR CAN RESULT IN AIRCRAFT OR EQUIPMENT DAMAGE AND POSSIBLE PERSONAL INJURY. WARNING! Towbars With Hydraulic Lifting Mechanism: The hydraulic lift mechanism (on those towbars so equipped) should only be used to raise the towbar to facilitate connection to the aircraft or tug. Release any hydraulic pressure when towing aircraft or moving towbar. WARNING! Towbars Should be Used with Category 1 Tugs: 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.

INS-1582 Towbar Usage Instructions 11/2003 | Rev. 03 Page | 4 USAGE PROCEDURE Aircraft Attachment: It is recommended that your towbar be attached to the aircraft first, and then connected to the tug to avoid possible aircraft damage. Ensure sliding pins are locked in place before towing aircraft. Tug Attachment: Damage to the towbar or aircraft can result from an excessive towbar angle during towing operations (See Figure 3). If aircraft with both high and low tow points are encountered, consider using two pintle hooks, as shown in Figures 4 & 5, so that the towbar is as level as possible during towing. Also pintle hook height should prevent contact of towbar wheels with the ground, during towing. (See Figure 5). Type Of Coupler: Damage to the towbar or aircraft can result while towing with the following type of couplers: - Lift Head - Vertical Side Swing Latch - Standard Duty Latch - Swivel Hook These types of couplers are known to cause binding and failure in the eyebolt. Indicators of eyebolt binding are wear on the outside diameter of the eye and indentations on the inside diameter. The failure will begin at the head of the eye. See Figure 6. FIGURE 3 - INCORRECT FIGURE 4 - CORRECT FIGURE 5 - CORRECT FIGURE 6 INS-1582 Towbar Usage Instructions 11/2003 | Rev. 03 Page | 5 USAGE PROCEDURE (continued) Type Of Coupler: Damage to the towbar or aircraft can result while towing with the following type of couplers: - Lift Head - Vertical Side Swing Latch - Standard Duty Latch - Swivel Hook These types of couplers are known to cause binding and failure in the eyebolt. Indicators of eyebolt binding are wear on the outside diameter of the eye and indentations on the inside diameter. The failure will begin at the head of the eye. See Figure 6. Figure 7 illustrates a pintle hook arrangement that is known to eliminate eyebolt binding. Tronair recommends using this type of hook on your tug. Eyebolt and Pintle Pin Size: Damage to the towbar 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. See Figure 8. To ensure proper towing and pushing, check to make sure that the pintle pin diameter is not too large for the eyebolt's inside diameter. Approximately a 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. Towing Angle: Damage to the towbar or aircraft can result from pushing an aircraft while maintaining too sharp of an angle between the tug and the towbar. Contact between the towbar weldment and tug must be avoided. It is recommended that the angle between the tug and towbar not exceed 90º. See Figure 9.
