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.

WARNING
Pressurized oil has enough force to pierce the skin
and cause a serious injury.
