3. When repairing or inspecting machine, with front structure
raised in air, firmly support front structure. When installing
supporting structure, check that it is rated and approved to
support the weight of the structure.
High-pressure loads between lift arm structure and support
can cause support to slip, causing boom to collapse,
leading to death or serious injury. Always install the
supporting structure on level and firm ground.
A supporting structure must be used, when disconnecting
front hoses or removing any other mechanical component
related to front structure. High-pressure oil can be ejected
from front hydraulic cylinder that can cause the lift arm to
suddenly lower or attachment movement resulting in death
or serious injury.
Engine Stop
Turn engine starter switch to "O" (OFF) position and remove
engine starter switch key.
Before lowering any equipment with engine stopped, clear area
around equipment of all personnel and bystanders. This
procedure will cause high-pressure air or hydraulic pressure to
be released to lower equipment.
Do not stop engine immediately after the machine has been
operated under load. This can cause overheating and
accelerated wear of engine components.
After the machine is parked, allow engine to run for at least five
(5) minutes before stopping the engine. This allows hot areas of
engine to begin to cool gradually.
• Do not leave operator's seat when there is a raised
load.
