SAFETY

VENTILATION FOR ENCLOSED AREA

Exhaust fumes from the engine can kill.
If it is necessary to start the engine within an enclosed area, or
when handling fuel, flushing oil, or paint, open the doors and
windows to ensure that adequate ventilation is provided to
prevent gas poisoning.

SIGNALMAN'S SIGNAL AND SIGNS

Set up signs to inform of road shoulders and soft ground. If the visibility is not good, position a signalman if
necessary. Operators should pay careful attention to the signs and follow the instructions from the signalman.
Only one signalman should give signals.
Make sure that all workers understand the meaning of all signals and signs before starting work.

EMERGENCY EXIT FROM OPERATOR'S CAB

If the cab door does not open for any reason, remove the glass from the rear window and use the window as an
emergency escape exit.
For details, see "EMERGENCY EXIT FROM OPERATOR'S CAB (PAGE 3-44)" in this manual.
