Employer of tug operator is responsible for providing sufficient operator training to ensure safe operation of towbar for pushback and towing operations The following are recommendations..4. Inspect the Towbar prior to each use:.4.. Visually inspect towbar tube for cracks at welded joints..4.. Visually inspect lunette eye assembly for damage and loose or missing hardware Visually inspect wheel carriage for damage and loose or missing components Visually inspect adapter to tube flange bolts Check head latch mechanism for proper travel and locking action in both forward and back positions.

WARNING: DO NOT attempt to tow an aircraft with a damaged towbar..5. Use the correct size Aircraft Tow Tractor: An important consideration for safe movement of an aircraft is using the correct category of tug for pushback and towing operations. Incidents are more likely to occur when using a tug that is either too large or too small for a particular aircraft. Consult the Aircraft Manufacturers Ground Towing Requirements chart to obtain tug draw bar pull and total wheel traction requirements based on aircraft and environmental conditions. Category Aircraft Maximum Takeoff Weight Tug Draw Bar Pull Up to 50,000 kg (0,000 lbs.) 4,000 kg (8,800 lbs.) Up to 50,000 kg (330,690 lbs.),000 kg (6,455 lbs.) 3 Up to 60,000 kg (573,96 lbs.) 38,000 kg (39,683 lbs.) 4 More than 60,000 kg (573,96 lbs.) 440,000 kg (88,84 lbs.)

6 3. Preventive Maintenance HALL Technical Services, LLC NOTE: Hall Industries recommends using this maintenance proceduree monthly (or as required by airlines maintenance procedures). Replace worn or damaged parts as needed. 3.. Replace Shear Pin Shear pin should spin freely by hand and the nut should not be tight to the head. A very small gap (0.005" 0.00" feeler gage) between the nut and the head is desirable. Seee Figure below. Figure. Inspection of shear pin and head/adapter clearance. 3.. Check Shear Pin Bushings. They should not be worn, cracked, or otherwise damaged. NOTE: Always replace bushings as a set. Never replace only one bushing Check clearance between head and adapter. With the shear pin removed, the head must be able to slide and pivot within the adapter plates by hand, but sometimess with some difficulty. A very small gap should exist between the head and the adapter (see Figure above). Both the Capture and Pivot bolts are shoulder bolts and the nuts should be able to be tightened up to the shoulder. However, if the adapter is excessively clamping the head slightly loosen Capture and Pivot bolt nuts by /8 of a turn to free up the head. E MB T OWBAR M ANUAL Page 6

7 HALL Technical Services, LLC 3.4. Check adapter/tube flange bolts (TB 8898 ) for tightness. Torque to 9 in lbs Check wheels and wheel carriage for bent, broken, or worn parts and security. Lubricate pivot points using Hall dry lubricant (Part number TB LUBE) Check head assembly for operation of lock mechanism; look for bending, security, etc. Lubricate pivot points using Hall dry lubricant (Part number TB LUBE) Inspect jaw assembly for looseness and worn or damaged parts Check latch mechanism to ensure proper travel back and forth, and that the locking pin locks in both the open and closed positions. Lubricate pivot points Check tow eye and hardware (tug attachment) for condition and security Check main body tube for bending or cracking. 3.. Clean, repaint or touch up paint as required. 3.. Inspect tags and labels. If damaged or missing replace (see the drawings in the attachment section for labels and placements) If the towbar is equipped with a hydraulic lift, check the fluid reservoir (in the down / collapsed position).
