EXTERNAL AIR TRANSPORT BY CH-47 HELICOPTER - CONTINUED
MACHINE DISASSEMBLY AND SECTIONALIZATION - CONTINUED
To facilitate machine disassembly and sectionalization, it is crucial that machine be positioned on
level ground, with tractor and scraper aligned and steering centered.
If possible, position machine in direction of helicopter's takeoff, so that pilot does not have to pick
up load, then turn aircraft into takeoff direction.
Whenever hydraulic hose quick disconnects need to be disconnected, operate control levers through
all positions (WP 0004 00) to relieve any trapped hydraulic pressure in hoses. This will facilitate dis-
connection of hoses.
Position machine on level ground, with tractor and scraper aligned and steering wheel centered. Move ejector fully
to the rear and close floor of bowl. Place transmission in N (Neutral) and lock, apply parking brake, and lower bowl
to the ground. Shut down engine. Block tractor and scraper wheels.
Use extreme caution when handling heavy parts. Provide adequate support and use assistance during
procedure. Ensure any lifting device used is in good condition and of suitable lift capacity. Keep clear of
heavy parts supported only by lifting device. Failure to follow this warning may result in death or injury
