vertical, lower load to the bottom.

g. Raise carriage and measure the distance from

where the center of the bottom carriage roller

stopped, to the bottom edge of the inner slide.

Distance must not be less than l/2 inch. Adjust

chain length at anchors (see figure 4-82) as

required to obtain this dimension.

while lift cylinder continues to retract), upright

rollers must be adjusted. Refer to paragraph 4-83.
