Be sure everyone is in the clear before slewing the super-
structure.
Never swing or position the attachment or load over per-
sons or vehicle cabs.
Never allow anyone to walk or work under the Shovel or
load while the Shovel is operating.
BRAKING THE SUPERSTRUCTURE
Braking of the superstructure from a slewing movement is carried
out first by returning the control lever (1) or (2), illustration Z24003
to the neutral position (N).
This procedure can be shortened by depressing pedal (3).
Swing Parking Brake
The parking brake for the swing gears is a spring loaded disk type
brake. This brake is switched ON and OFF with toggle switch (4).
NOTICE
The swing parking brake must only be applied with the
Superstructure at complete standstill. Applying the parking
brake with superstructure still slewing may result in severe
damage to the brake.
Use the swing parking brake only in an emergency situa-
tion for stopping the rotating superstructure.
If the parking brake has been used for emergency stop-
ping, it is necessary to shut down the Excavator and to
have the parking brake of the swing gear inspected and
repaired if necessary. Contact your Komatsu dealer for
support.
