Safety
1. While operating a machine, do not let people enter the
operational area. The sudden collapse of the front
structure caused from a hose failure may result in
injuries or death.
2. When stopping or parking the machine, lower the front
structure to the ground. If not, the sudden collapse of
the front structure caused from a hose failure may
result in injuries or death.
3. When repairing or inspecting the machine, with the
front structure raised in the air, firmly support the front
structure. When installing the supporting structure,
verify that it can handle the load.
High-pressure loads between the boom structure and
support may cause the support to slip, causing the
boom to collapse, leading to injuries or death. Take the
installation location of support and supporting surface
into consideration.
A supporting structure must be used, when
disconnecting front hoses or removing any other
mechanical component related to the front structure.
High-pressure oil can be ejected from the front cylinder
to release its static pressure and force. A sudden shift
of a front structure load may cause a boom collapse
leading to injuries or death.

and cause a serious injury.
