.
WA R N I N G

Outrigger is heavy. Stand clear of outrigger to avoid injury.
a. Position Wrecker.
Position the wrecker on
firm, level ground whenever possible. Determine
which type of lifting is necessary (i.e., rear lift, lift
and swing, heavy rear lift or a heavy side lift) and
position the wrecker accordingly. For heavy loads,
the wrecker should be positioned for a direct rear
lift with the elast amount of boom extension.
N O T E
Refer to the safe load data plate
located near the crane controls. Select
the lifting method (with or without
outriggers) and crane radius that will
permit crane operation within safe
limits while lifting the load. Position
the wrecker close enough to the load
to operate the crane at the radius you
have selected.
