OPERATING CONTROLS AND PROCEDURES RT9130E-2 OPERATOR MANUAL
3-46 Published 3-1-2018, Control # 559-03
NOTE: Automatic rear axle oscillation lockout will activate
when the boom swings right or left of the crane
centerline.
To swing the boom, the Swing Control Lever is pushed
forward, away from the operator, to swing clockwise, or
pulled back, toward the operator, to swing counterclockwise.
Always operate the control lever 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 and Lowering the Boom
Elevating the Boom
To elevate the boom, pull the Boom (lift) Control Lever back,
toward the operator, and hold until the boom reaches the
desired elevation level.
Lowering the Boom
To lower the boom, push the Boom Control Lever forward,
away from the operator, and hold until the boom is lowered to
the desired position.
Telescoping the Boom
Extending the Boom
For a machine not equipped with an auxiliary hoist, push the
Boom In/Out Control Lever forward to extend the boom.
If the crane is equipped with an auxiliary hoist, push on the
top of the Telescope Control Foot Pedal.
Retracting the Boom
For a machine not equipped with an auxiliary hoist, pull the
Boom In/Out Control Lever to the rear to retract the boom.
If the crane is equipped with an auxiliary hoist, push on the
bottom of the Telescope Control Foot Pedal.

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.
WARNING
Falling Load Hazard!
Keep the area above and below the boom clear of all
obstructions and personnel when elevating the boom.
DANGER
Long cantilever booms can create a tipping condition,
even when unloaded and in an extended, lowered
position.
Keep the area beneath the boom clear of all obstructions
and personnel when lowering the boom.
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.
DANGER
Tipping Hazard!
Check the load chart for the maximum load at a given
radius, boom angle, and length before extending the
boom with a load.
DANGER
Two-blocking Hazard!
When extending the boom, simultaneously let out the
hoist cable to prevent two-blocking the boom nose and
hook block.
CAUTION
Before extending the boom, ensure the large access
cover on top of the boom base section is installed.
WARNING
Crushing Hazard!
When retracting the boom, the load will lower unless the
hoist cable is taken in at the same time.
