• If water gets into the electrical system, electric devices will
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.
• If high-pressure water is sprayed directly onto camera, it
may cause failure. Defective camera cannot monitor sur-
rounding area. When cleaning, do not allow the high-pres-
sure water to get into camera directly, and wipe off any dirt
with soft cloth.

injured. Put proper stepladder or step on the level and firm ground, and clean the camera in secure posture.
PRECAUTIONS FOR INSIDE OPERATOR'S COMPARTMENT

the control devices, it may obstruct operation and cause the machine to move unexpectedly, resulting in
serious personal injury or death.

and may cause serious personal injury or death.
