Operating the 01-1202-000 Towbar:
**Reference only information. Review manual prior to operation.

• It is important to verify that the towbar is sized properly for both the aircraft to be moved and the tug that is going to be doing the moving.
• Make sure the towbar is securely connected to the aircraft. The towbar should be as close to horizontal as possible.
• The angle between the tug and the towbar should be roughly 90 degrees.
• Safely moving the aircraft requires two people.
• Correctly size the towing eye for the pintle hook used on the tug.
• Match the pintle hook and towbar eyebolt.

Towbar Checklist:

• Check towing eye for bending, excessive wear and/or deformity. Contact Tronair for repair/replacement if towing eye is bent, excessively worn or deformed.
• Check towing eye mounting bolts. Ensure fasteners are not loose or missing. Tighten to 25 ft-lbs or replace as required.
• Ensure that the towing eye does not turn; if the towing eye can turn it indicates that the centering pin within the shock assembly may have been broken and repairs are needed.
• Check the shock assembly for preload on the spring by pulling on the towing eye. If the shock can be moved by hand it indicates that the spring is worn out and Tronair should be contacted for repairs.
• Inspect the towbar tube for cracks, gouges greater than 1/16 inch, and bends or deformities. A damaged or bent towbar should not be used. Contact Tronair for replacement.
• Check the casters to ensure the swivels operate freely and the bearings are not missing. Replace if needed.
• Ensure that the caster mounting fasteners are not loose or missing. Tighten or replace as required.
• Check the caster mounting plate and channel. If the caster mounting plate is bent or broken or if the channel welds are broken, contact Tronair for repairs.
• Inspect the lifting handle at the towing eye end. Replace or repair the handle if it is missing or damaged. Ensure the mounting fasteners are not loose or missing. Tighten or replace as required.
• Check the towbar undercarriage. Inflate the pneumatic tires to the proper pressure; fix any air leaks or replace if needed, ensure the wheels can rotate freely, wheel rims are not bent, and tire axle is not bent. Ensure mounting fasteners are not loose or missing; tighten or replace as required. Grease the tire axle every 90 days to 6 months.
• Inspect towing head attachment ball loc pin. Verify that the factory supplied ball loc pin is used; contact Tronair for replacement if required. Do not substitute without Tronair approval.

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.
