OPERATING CONTROLS AND PROCEDURES
CAUTION
Disengage the swing brake and the swing lock pin or 360°
swing lock before attempting to swing.
The operator must select the proper load chart and RCL
program for the outrigger position selected.
Never push or pull the swing control lever through neutral
to the opposite direction to stop swing motion. Use the
swing brake foot pedal to stop swing rotation.
NOTE: Automatic rear axle oscillation lockout will activate
when the boom swings right or left of the crane
centerline.
To swing the turntable right (clockwise), push the SWING
control lever forward away from yourself. To swing the
turntable left (counterclockwise), pull the swing control lever
back, toward yourself. Always operate the control level with a
slow, even pressure. Use the swing brake foot pedal to stop
rotation, then position the SWING BRAKE switch to ON to
prevent further rotation.
Elevating The Boom (Single Axis Controller Option)
Keep the area above and below the boom clear of all
obstructions and personnel when elevating the boom.
To elevate the boom, pull the BOOM (lift) control lever back,
toward yourself, and hold until the boom reaches the desired
elevation level.
Lowering The Boom (Single Axis Controller Option)
Keep the area beneath the boom clear of all obstructions
and personnel when lowering the boom.
Long cantilever booms can create a tipping condition,
even when unloaded and in an extended, lowered
position.
CAUTION
When lowering the boom, simultaneously let out the hoist
cable to prevent two-blocking the boom nose and hook
block.
The closer the load is carried to the boom nose, the more
important it becomes to simultaneously let out the hoist
cable as the boom is lowered.
