
Make sure the worksite has sufficient strength to firmly
support the machine.
When working close to an excavation or at road
shoulders, operate the machine with the tracks positioned
perpendicular to the cliff face with travel motors at the rear,
so that the machine can more easily evacuate if the cliff face
collapses.
 If working on the bottom of a cliff or a high bank is required,
be sure to investigate the area first and confirm that no
danger of the cliff or bank collapsing exists. If any possibility
of cliff or bank collapsing exists, do not work on the area.
 Soft ground may collapse when operating the machine on
it, possibly causing the machine to tip over. When working
on soft ground is required, be sure to reinforce the ground
first using large pieces of steel plates strong and firm
enough to easily support the machine.

Note that there is always a possibility of machine tipping
over when working on rough terrain or on slopes. Prevent
machine tipping over from occurring. When operating on
rough terrain or on slopes:

Reduce the engine speed.

Select slow travel speed mode.
 Operate the machine slowly and be cautious with
machine movements.
Install OPG Guard
In case the machine is operated in areas where the possibilities
of falling stones or debris exist, equip Hitachi OPG guard.
Consult your authorized dealer for installing the OPG guard.
The guard can be compliant with ROPS standards depending
on the machine specifications.
In order not to impair operator protective structure:
Replace damaged ROPS or OPG guard. Never attempt to repair
or modify the guard.
ROPS: Roll Over Protective Structure
OPG: Operator Protective Guard
