played), move the machine to a safe place and slowly lower the work equipment to the ground. Then
immediately ask your Komatsu distributor for the inspection and repair.

parking brake cancel switch to the releasing direction (a).
Slowly perform the hydraulic drift of the upper structure to
the safe direction .
