Transmission Operation.
NOTE
The APC 100 is not active when driving from the
superstructure cab. Thus transmission operation is
entirely manual.
The following information outlines proper shift points for manual operation.
CAUTION
Do not downshift to a lower gear if the crane is
traveling at a greater speed than the maximum speed
of the lower gear.
To avoid hard shifting, the road speeds at which the shift should be made are
shown on the following chart.

Stepping of changes should be progressive. It is not always necessary to start a
crane in 1st gear. Up to 3rd gear may be used when starting on reasonably level terrain.
