(c) Adjust the pedal end of the swing brake cable by
increasing the thread length as indicated in Figure 1
until the swing brake pedal is operating in the 4 to 5
click range. After the adjustments are made, sufficient
thread must remain so that all the threads of the jam nuts
are engaged.
Note: Any adjustment required on the swing speed
reducer end of the swing brake cable will require
that the swing brake cable is disconnected from the
swing brake pedal.
(d) Set the swing brake and begin to attempt to swing the
machine against the swing brake. You should exercise
caution in doing this until you know that the swing
brake is in good working order and will hold against the
swing pressure. Once you have verified that the swing
brake is holding, the engine RPM should be brought up
to full governed speed slowly.
(e) If the swing brake fails to prevent the boom from rotat-
ing or if the swing brake pedal continues to operate in
the 6 or 7 click range, the swing brake cable and/or the
brake discs may need to be replaced.
