GENERAL PRECAUTIONS
2-13

To ensure safety, always face the machine and maintain
three-point contact (both feet and one hand, or both hands
and one foot) with the handrails and steps (including the
track shoe) to ensure that you support yourself.
q
Do not grip the control levers when getting on or off the
machine.
q
Never climb on the engine hood or covers where there are
no non-slip pads.
q
Before getting on or off the machine, check the handrails
and steps (including the track shoe). If there is any oil,
grease, or mud on the handrails or steps (including the
track shoe), wipe it off immediately. Always keep these
parts clean. Repair any damage and tighten any loose
bolts.
q
Do not get on or off the machine while holding tools in your hand.
MOUNTING AND DISMOUNTING

Never jump on or off the machine. Never get on or off a moving machine.

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 attachments. There is a hazard of falling and suffering seri-
ous injury.
CRUSHING OR CUTTING PREVENTION
The clearance around the work equipment will change according to the movement of the link. If you get caught,
this may lead to serious personal injury. Do not allow anyone to approach any rotating or telescoping part.

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

To prevent burns from hot oil spurting out when checking or
draining the oil, wait for the oil to cool to at temperature
where it is possible to touch the cap or plug by hand before
starting the operation. Even when the oil has cooled down,
