OPERATING CONTROLS AND PROCEDURES
6. Engage the swing gear:
a. Brake pedal: Release the brake pedal as you
move the control lever in the direction you want the
superstructure to rotate.
b. Control lever: Move the control lever in the
direction you want the superstructure to rotate.
NOTE: With the Brake pedal function, swing movements
are not braked automatically. If you let go of the
control lever or move it to the neutral position, the
swing movement will continue; use the brake
pedal to stop the rotation.
Always operate the control lever with a slow, even pressure.
Depending on your configuration; use the swing brake pedal
or control lever to stop rotation, then push the Swing Brake
switch once, the icon will turn red, to engage the swing brake
preventing further rotation.

RT9150E OPERATOR MANUAL
Rotating Superstructure with Counterweight
The RCL only disables the swing operation if the RCL
c o d e w a s e n t e r e d c o r r e c t l y a n d t h e R C L i s n o t
overridden.
Therefore always check before rotating whether the RCL
code is valid for the current rigging mode displayed. This
prevents swing operations from being allowed within
impermissible ranges and the crane from overturning.
You may only rotate the superstructure with a rigged
counterweight if the crane is supported by a sufficient
outrigger span and the permissible working radii are
observed. Otherwise the crane will overturn during rotation.
The current rigging mode is registered by the RCL code
entered, and the RCL disables the swing operation if it is not
permitted.
