least 9 feet and lift at least 10 feet. It should be movable, or
provisions must be made to move the vehicle as the powerpack
is removed.

screws. Screws must be in a position to be removed easily. If
not, move vehicle until screws can be easily accessed.

pack after removal.
D Provide a stand or frame to hold the powerpack after removal.
If unavailable, set the powerpack on wood blocks (p 3-24).

roll out of control. When the powerpack is discon-
nected, the vehicle is without brakes.

G Disconnect both battery ground cables (p 6-44).
H

ing wheel to right position.

doing maintenance in the engine compartment

hop mode. Contact with rotating fan can cause
