Mounting and dismounting
z Never jump on or off the machine. Never get on or off a mov-
ing machine.
z If the machine starts to move when there is no operator on
the machine, do not jump on to the machine and try to stop
it.
No people on attachments
Never let anyone ride on the work equipment, or other attach-
ments. There is a hazard of falling and suffering serious injury.
Do not get caught in articulated portion
z If the clearance at the articulating portion changes, it will
lead to serious personal injury.
Do not allow anyone to come inside the articulation range.
z Never enter or put your hand, arm, or any part of your body
in the movable portion between the work equipment and
machine or between the cylinder and the work equipment.
If someone operates the control levers by mistake, the gap
between the work equipment and machine and between the
cylinder and work equipment will change, and you, your
hand, or arm will be caught and you may suffer serious
injury.
If you have to go into a movable portion, always take action
to secure the work equipment and ensure that it cannot
move.
Prevention of burns
Hot coolant
z To prevent burns from hot water or steam spurting out when
checking or draining the coolant, wait for the water to cool to
a temperature where it is possible to touch the radiator cap
by hand before starting the operation. Even when the cool-
ant has cooled down, loosen the cap slowly to relieve the
pressure inside the radiator before removing the cap.
Hot oil
z
To prevent burns when checking or draining the oil, wait for
the oil to cool to a temperature where it is possible to touch
the plug by hand before starting the operation. Even when
the oil has cooled down, loosen the plug slowly to relieve the
internal pressure before removing the plug.
