CAUTION
TURNOVER PREVENTION DEVICE
Be sure to perform inspection (pre-start inspection) before starting operations
to make sure that this device works.
As ground reaction force is lowering, a warning indicating that turnover is
close is given. Slow down the operating speed and immediately operate the crane
to a safe side. If ground reaction force further lowers, the following crane
movements stop automatically. In this case, extreme care must be used because
the crane may turnover due to swing of load if the crane speed is fast.

Overload is strictly prohibited. This device is designed for operations within
the rated load in principle and not for prevention of overload. Do not have
too much confidence in this device. If the crane inclines due to swing of load
or grounding on rough terrain, it could turnover.
