cause malfunctions, and the machine will cause error. If
the machine cause error, it may move unexpectedly and
cause serious personal injury or death. When washing the
machine with water or steam, do not allow the water or
steam to come into direct contact with electrical compo-
nents.

may cause failure. Do not allow the high-pressure water to
get into camera directly. When cleaning the camera, wipe
off any dirt with soft cloth.

fall and be injured. Put proper stepladder or step on the level and firm ground, and clean the camera and
mirror in secure posture.
PRECAUTIONS FOR INSIDE OPERATOR'S COMPARTMENT
• When entering the operator's compartment, always remove all mud and oil from the soles of your shoes.

ous accident.
• Do not leave tools or machine parts lying around inside the operator's compartment. If tools or parts get into
the control devices, it may obstruct operation and cause the machine to move unexpectedly, resulting in
serious personal injury or death.
• Do not stick suction pads to the window glass. Suction pads act as a lens and may cause fire.
• Do not use a cellular phone when driving or operating the machine. This may lead to mistakes in operation,
and may cause serious personal injury or death.
• Never bring any dangerous objects such as flammable or explosive items into the operator's compartment.

checks and add to the contents if necessary.

gauges, smoke, oil leakage, etc., or any abnormal display on the warning devices or monitor), report to the per-
son in charge and take the necessary action. Do not operate the machine until the problem has been corrected.
