Ensure good visibility
This machine is equipped with mirrors to improve the visibility,
but even with mirrors, there are places, which cannot be seen
from the operator’s seat, so always be careful when operating.
When operating or traveling in places with poor visibility, if it is
impossible to confirm the condition of the job side or obstacle is
in the area around the machine, there is danger that the
machine may suffer damage or the operator may suffer serious
personal injury. When operating or traveling in places with poor
visibility, always observe the following items strictly.

If the visibility cannot be sufficiently assured, position a flag-
man if necessary. The operator should pay careful attention
to the signs and follow the instructions of the signalman.

Only one signalman should give signals.
z
When working in dark places, turn on the working lamp and
front lamps installed to the machine, and set up additional
lighting in the work area if necessary.

Stop operations if the visibility is poor, such as in mist, snow,
rain, or dust.
z Check the mirrors on the machine before starting operations
every day. Clean off any dirt and adjust the view to ensure
good visibility.
Precautions related to ventilation exhaust gas
Engine exhaust gas includes substances that may harm your
health or even kill. Always select a place with good ventilation
when starting the engine or operating the machine.
If it is necessary to start the engine or run the machine inside a
building or underground, where the ventilation is poor, take steps
to remove the exhaust gas and bring in ample fresh air.
