Ensuring good visibility
If it is impossible to determine the condition of the working area
and detect obstacles due to low visibility, there is a hazard of dam-
age to the machine as well as severe injury. Before starting to
drive, sound the horn to warn people in the area. When operating
or travelling in places with poor visibility, always observe the fol-
lowing items strictly:
 Clean the windows and headlights to ensure optimum visibil-
ity.
 Adjust the mirrors so that the rear of the machine can be seen
clearly from the operator's seat. Keep the mirrors clean.
 Ensure that the entire lighting system is in perfect working
order and adjusted as specified in the applicable regulations.
 If the visibility cannot be sufficiently assured, position a sig-
nalman if necessary. Operators should pay careful attention
to the signs and follow the instructions from the signalman.
 Only one signalman should give signals.
 When working in dark places, turn on the machine's work
lights, and set up additional lighting in the work area if neces-
sary.
 Stop operations if the visibility is poor, such as in mist, snow,
rain, or dust.
 Immediately replace broken windows.
Precautions related to exhaust gas
 Engine exhaust gas includes substances that may harm your
health or even cause death. Ensure 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.
