(7) For the sake of safety, the user must check slewing ring bolts with 1800N.m
tightening torque after the initial 100 operating hours. Then check and tighten them
after 300 operating hours. After that, do the checks every 500 operating hours.
(8) When operator has to leave the machine during traveling or transportation, never
rely solely on the slewing brake to lock the slewing mechanism. Even though the
slewing brake is applied, the superstructure may still slew, because it is not a
positioning lock.
(9) Activating slewing brake switch to stop slewing operation abruptly should be
avoided, since it may cause damage to the superstructure.
