-2- 1. WARRANTY Adaptive Engineering Ltd. Warrants each Mobilift AX/R to be free from manufacturing or material defects for two years from the date the product was put into service. Damages caused by vandalism or abuse are not covered by this warranty. For assistance, parts or repair information please call 1-800-448-4652 or 1-403-243-9400.
-3- 2. CAUTIONS: General 1. It is the responsibility of operating staff to ensure that the aircraft is not damaged while the wheelchair lift is in use. 2. All precise maneuvering (i.e. alignment with aircraft or parking) should be performed using the push handles. Do not tow lift too close to aircraft. 3. Do not attempt to crank up the lift deck from on the lift. A lift operator on the ground is required. 4.
-4- 3. FEATURES Convenience Cranking System The high-efficiency crank system is counter-balanced to allow two adults to be lifted to maximum height with very little effort in less than 45 seconds. Self-leveling Ground Contacts Automatic self-leveling of lift on uneven ground. Tow Bar Tow bar with integral brake release allows towing by tarmac tractors. Spare Tire A spare tire is attached to the Mobilift. The “quick release” design allows a wheel to be changed in less than 2 minutes without tools.

-7- 6. OPERATION DETAILS Bracketed numbers refer to parts that are labeled on figures in Section 8. Operators who are using the lift with the Beech 1900 and Fairchild Metroliner, please refer to special instructions at the end of this section. To Move The Lift: I. Raising Lift onto Wheels a) The first step is to crank the lift up onto its wheels. To do this, turn the wheel crank handle [16] clockwise until the wheels are in the full down position.
-8- III. Aligning Lift with Aircraft a) Carefully push the lift toward the aircraft and align the ramp with the doorway. b) If there are stairs in place, bring the lift as close as possible to the stairs, there is a bumper [47] on the front of the tow bar to reduce the chance of damaging the stair or lift if contact is made. c) If there are no stairs in place, bring the lift close to the fuselage of the aircraft using caution not to push the end of the deck under the fuselage, see figure below.
-9- IV. Stowing the Lift a) Park the wheelchair lift away from the aircraft with the wheels up, or in an enclosure, so there is no possibility of it causing damage to aircraft or other airport equipment. b) If the lift could be subjected to high winds it should be fastened securely to a permanent fixture or be stowed inside an enclosure. An optional enclosure is available from the manufacturer. c) The Mobilift is designed for durable reliability but it could be damaged by foreign object debris (FOD).
- 10 - III. Positioning the Passenger and Attendant on Lift The fore and aft location of the aircraft entrance will determine whether the passenger should be loaded onto the lift facing towards or away from the aircraft. If the entrance door is forward of the passenger seating, the passenger should be backed onto the lift facing away from the aircraft. If the entrance door is aft of the passenger seating, the passenger should be loaded onto the lift facing towards the aircraft.
- 11 - IV. Raising the Lift To raise the deck, pull the deck crank handle [15] out and turn it clockwise until the deck is 2 or 3 inches above the sill of the aircraft door. (Note: When the deck height and lift position for a particular aircraft is established, the operator may mark the deck height on the lift post for future convenience.) IMPORTANT: • Watch to ensure that the deck and its attachments do not contact the aircraft when raising or lowering the deck.
- 12 - VI. Transferring the Passenger to the Aircraft With the bridge ramp in proper position, the attendant on the lift can move the passenger across the ramp and into the aircraft. VII. Retracting the Bridge Ramp With the passenger and attendant fully inside the aircraft and clear of the bridge ramp, the operator raises the deck 2 or 3 inches then fully retracts the bridge ramp by pulling down and turning the bridge ramp extension crank clockwise.
- 13 - Operation of the Lift with Beech 1900 and Fairchild Metroliner Operators using either of these aircraft must note the following special instructions for these difficult-toaccess planes. In both cases, an experienced spotter must be positioned at the propeller to protect it, because of the proximity of the spinner tip to the airplane door. Beech 1900 1. The Mobilift should be moved towards the aircraft in line with the door, and stopped when lift post A is 10 to 12 inches away from the spinner tip.
- 14 - Fairchild Metro With the Metro proceed as follows, referring to diagrams at the end of these instructions: 1. Station an experienced person at the propeller to be sure the lift does not touch the blades or spinner. 2. The purpose is to get the lift pointing at the door, but sitting at an angle of about 10o . In order to do this, lift post A must be about a foot ahead of the spinner tip - that is between the spinner and the plane. 3.
- 15 - Fairchild Metroliner Path of travel follows lift post A Mobilift positioned for use 8.
- 16 - a) When cranking the lift, the operator should maintain a slight outward pull on the crank handle. This ensures the handle does not tend to fold while cranking. b) When cranking the lift up, the more weight there is on it, the harder it will be to crank. Cranking the deck down will feel about the same as cranking up because of the patented load activated braking system. The brakes are actually applied by the load on the deck, so increased load on the deck makes it harder to crank down.
- 17 - 7. MAINTENANCE The wheelchair lift is safety equipment. It must be inspected officially at least once a year, or in high use areas, after every 500 uses. In addition, the day-to-day operator of the lift should make a habit of glancing at the main lifting cables on the left side of the lift for any sign of wear or damage. As with any piece of safety equipment, the Mobilift AX / AXR must be on a documented preventive maintenance program.
- 18 - II. Wheel Bearings Wheel bearings are sealed and do not require any lubrication III. Spare Tire In the event that the spare tire is required, the following procedure should be followed. a) Crank the lift down off of its wheels. Continue cranking until the tires are clear of the ground. b) The spare tire can be removed from its mount by removing the retaining pin and sliding it off of the mounting axle. c) Disengage the parking brake on the tire being changed by pulling down on the push handle.
- 19 require tightening. Since the brake can be released with either the tow bar or push handles, both systems should be checked. Adjust each brake release system individually (4 cables overall). Retighten all cable adjustment locking nuts. If the brakes do not provide sufficient braking force when the push handles and tow bar are released, the following adjustment should be performed. a) With the tow bar and push handles released, check that both cables to each brake lever are slack.

- 26 - 10. SUGGESTED MINIMUM INSPECTION REPORT Mobilift AX / AXR Wheelchair Lift, (Minimum inspection once per year) 1. Perform a complete general visual inspection for loose fasteners and for damaged or missing components. 2. With the deck at ground level, a 10 lb. (5 kg) pull on the middle of each of the outer lifting cables should separate the cables between 3-1/4 and 3-3/4 inches (8 and 10 cm) for the AX and between 3-3/4 and 4-1/4 inches (9 to 11 cm) for the AXR. 3.
- 27 23. Check that the automatic leveller bar is free to move when the lift is on its wheels. 24. With the deck raised to approximately 36 inches (90 cm), check that the bridge ramp rolls out and returns smoothly using its crank handle. It should not be possible for the ramp to be pushed in or out without using the crank. 25. Check that the bridge ramp centers positively and smoothly when fully extended. 26. Check that the bridge ramp centering cables are tight when the ramp is centered. 27.
