How to release when turn over prevention device is found to be out of order
If the crane cannot be operated due to trouble in the turn over prevention device, store the crane
in accordance with steps as follows:
● Step 1
The release switch for turn over prevention
device is located inside of the cover near the
outrigger valve.
Operate the crane while the release switch is
being pushed up.
If the crane is operated with the release switch
pushed up, the device loses the functions as

Operate the crane by paying special attention
that the crane will not be overturned.
