12-63. M984E1 CRANE OPERATION (MANUAL CONTROLS) (CONT).
WARNING
Do not raise vehicle tires off ground with outrigger
jack cylinders. Vehicle could roll causing serious
injury or deat.h.
Chock front wheels when using outriggers to prevent
vehicle from rolling.
Crane must be level from side to side. Use of crane in
unlevel position can cause vehicle to tip over causing
serious injury or death.
NOTE
Left and right outrigger jacks can be operated from
left or right side control panels.
Operate left and right outrigger jack (LH O/R JACK
and RH O/R JACK) control levers at the same time.
Crane movement from one lever may be slower than
the other when operating two levers together.
Vehicle weight should be off rear axle just enough so
tires still have firm contact with ground but do not
bulge from weight.
(17)
Move left outrigger jack (LH O/R JACK) and right outrigger jack (RH
O/R JACK) control levers (20 and 10) to DOWN position. Lower left
and right outrigger jack cylinders (17 and 7) until vehicle weight is off
rear tires.
