Table 2-1. Controls and Indicators - CONT
When the 6 alignment arms are pinned in the down posi-
tion, they guide the spreader when the spreader is being
lowered onto a container. They are pinned in either
the up or down position for lifting and transporting.
The eyebolt on the end of the rod is placed over the
capscrew to move the alignment arm to the up or down
position, when the spring pin is withdrawn by the control
When the spreader is suspended the cam locking rod
is in the down position, and the hex nut is in the notch
in the locking cam. When the cam locking rod is in this
position the twist locks cannot be rotated. When the
spreader is lowered onto a freight container, the rod
moves upward which moves the hex nut out of the
notch in the locking cam, and the twist locks can be
rotated to the locked position. When the spreader and
container are lifted the rod falls to the down position
and the hex nut falls into a second notch in the locking
cam, which prevents the twist locks from being moved
out of the locked position. If necessary, the cam locking
rod can be pushed up manually to disengage the hex
nut, and the twist locks can be rotated to either the
locked or unlocked position.

2-2 OPERATOR/CREW PREVENTIVE MAINTENANCE CHECKS AND SERVICES
