SAFETY
DO NOT GET CAUGHT IN ARTICULATED PORTION
q 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.
q 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
q 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 radi-
ator cap by hand before starting the operation. Even when
the coolant has cooled down, loosen the cap slowly to
relieve the pressure inside the radiator before removing the
cap.
Hot oil
q 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.
