4.17.1.10 Remove the chocks from the launch vehicle LV front axle wheels.
CAUTION
Do not engage the launch vehicle transmission and drive it backwards, in excess of 2 mph
(3.2 kph), the A-frame could be damaged.
When retracting the slide frame, it is essential that the vehicle chassis and the slide frame
are both in line longitudinally. If the vehicle chassis is at a different angle to the slide
frame the energy chains that run down the inside of the slide frame beams will be
damaged, and the launcher will not sit on the twist lock blocks when lowered.
4.17.1.11 Set the launch vehicle transmission to reverse and release the parking brake. Ensure
the case lock is engaged (all wheel drive).
4.17.1.12 Place personnel at either side of the rear of the slide frame to watch and ensure that
the energy chains do not become trapped between the vehicle chassis and the slide
frame.
CAUTION
Stop the reverse and adjust the height of the tail lift if the tail lift will not pass under the
energy chain or between the top of the home bank ramp module and the underside of the
A-frame lower cross member of the A-frame. Failure to observe this instruction will result
in equipment damage.
4.17.1.13 Slowly reverse the launch vehicle and retract the slide frame.
4.17.1.14 If the tail lift WILL clear the slide frame energy chain and pass between the top of the
home bank ramp module and the underside of the A-frame lower cross member of the
A-frame then move to 4.17.1.20.
NOTE
Carry out procedures 4.17.1.15 to 4.17.1.18 ONLY if tail lift will NOT pass under the energy
chain or between the top of the home bank ramp module and the underside of the A-frame
lower cross member.
4.17.1.15 Stop the launch vehicle, set the transmission to neutral and apply the parking brake.
4.17.1.16 In the launch vehicle cab, to the right of the driving position, on the left side of the
center console, set the 4-position mode selector rotary switch from 3 to position 2.
Make sure the PTO engages and the engine rpm goes to high idle.
4.17.1.17 On the tail lift pendant, press and hold the LIFT UP switch to raise the tail lift platform.
Make sure the lift hydraulic cylinders extend to raise the tail lift platform.
4.17.1.18 Release the LIFT UP switch on the tail lift pendant when the tail lift platform height is
sufficient to clear the slide frame energy chain or pass through the space between the
top of the home bank ramp module and the underside of the A-frame lower cross
member.
4.17.1.19 Set the 4 position switch to position 3 and continue to fully close the slide frame.
