Lowering the Cable. To lower the cable, the HOIST control lever is "pushed forward", away from the
operator, to the DOWN position and held until hook or load is lowered to desired height.
Raising the Cable. To raise the cable, the HOIST control lever is "pulled back", toward the operator, to
the UP position and held until hook or load is raised to desired height.
HOIST FREE FALL This feature
provides faster lowering of the cable
than can be obtained by power opera-
tion. A finger actuated pull control is
mounted on the hoist control lever
for convenient and easy transition
from normal operation.
Free fall operation should be practiced with very light
loads and short falls until a feel for the operation is
developed. Smooth and gradual snubbing of loads is
necessary to avoid high shock loads. Free fall loads
are limited to a maximum of 2845 lbs. or 30% of
the load chart capacity, whichever is less.
Hoist free fall is normally used only for lowering concrete buckets, fast return of empty hooks or
emergency release of loads.
PRELOAD OPERATION CHECK.
After the machine has been readied for service, an operational check of all crane functions (with no load
applied) should be performed. Accomplish the Preload Check as follows:
OPERATE ENGINE AT OR NEAR GOVERNED RPM DURING PERFORMANCE OF ALL CRANE
