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. The high alignment
bumper [46] will set the minimum spacing for the Boeing 737 and MD80.

Contact not necessary
d) Once the lift is in position, release the push handles allowing them to return to the upright
position automatically applying the parking brake.
e) Extend the outriggers by releasing the safety locking handles and pulling the outrigger
handles outward to the fully extended position. As a safety feature, the lift deck cannot be
raised unless the outriggers are extended. The two outriggers on each side of the lift are
interconnected to make them move at the same time. Watch that the outriggers do not
contact the propeller, landing gear or other obstacles while extending.
f) Lower the lift to the ground by turning the wheel crank handle [16] counter-clockwise. Note
that the lift is designed to rest on the two outriggers of the tow bar end, and the automatic
leveling device on the push handle end of the lift. The two outriggers on the push handle
end of the lift contact the ground but do not take load unless strong tipping forces are
applied to the lift.
Cautions:
• Use extreme caution when approaching the aircraft to avoid damaging contact between the
lift and any part of the aircraft.
• Perform all maneuvering near the aircraft with the push handles only. Do not tow the lift
directly up to the aircraft.
