9.
Release the parking brake and carefully idle the unit forward to the
aircraft and make soft contact of the rubber platform bumper with the
aircraft. Use the overhead spotlight as necessary for night operation.
10.
VERY IMPORTANT:
Do not adjust the stair height once in contact with
the aircraft. If further adjustment is required, carefully back away and
re-start this procedure.
11.
Place transmission shifter to neutral position and set the parking brake.
12.
Hold the A-FRAME UP/DOWN switch UP to move the stair away from the
aircraft until approximately 3 inches of clearance is achieved.
13.
Press the STABILIZER UP/DOWN switch DOWN and hold until all
stabilizers are fully lowered. “STABILIZER NOT RETRACTED” indicator
light will illuminate.
To avoid crushing injury to feet, stay clear of stabilizers.
14.
Hold the A-FRAME UP/DOWN switch UP to allow the pressure to be
taken off the rigid ratchet tooth. Hold the A-FRAME RELEASE switch
and lower the A-Frame until it is almost in contact with the aircraft.
Release the A-FRAME RELEASE switch and lower the A-Frame lock
lever against the rigid ratchet tooth.
15.
Switch the engine OFF. For night time operation, turn the ignition switch
to ON (leave power on) in order to power the stair lights. If the lights will
be used for more than 30 minutes, do not turn the engine OFF.
16.
Lower the flip step at the bottom end of the stair. Climb the stair to the
platform and release the appropriate wing panel lock by pushing down on
the latch handle. Move the panel back to the full open position. Stand as
far back of the panels as possible so you are still protected by the wing
panels if you should fall. Now the aircraft door may be opened and
stowed. Care must be taken to stay away from any open areas while the
wing panel is in the retracted position and the aircraft door is being
positioned. After opening the door, move the wing panels ahead, as close
to the aircraft as possible and be sure the panels lock in position by
engaging in the closest detent notch.
17.
The wing panels must be as close to the aircraft (or loading bridge) as
possible. The space must be at a minimum so persons can not fall
through the opening.
18.
Check that the wing panels are secure by being sure they will not move
when force is applied to them.
