6 GENERAL PRECAUTIONS
WARNING: for reasons of
safety, always follow these
safety precautions.
VENTILATION FOR ENCLOSED AREAS
Exhaust fumes from the engine can kill.
• If it is necessary to start the engine within an enclosed area, or you handle fuel, flushing oil, or paint, open
the doors and windows to ensure that you provide adequate ventilation to prevent gas poisoning.
• If opening the doors and windows still does not provide adequate ventilation, set up fans.
PRECAUTIONS WITH CAB GLASS
If by mistake the cab glass on the work equipment side should crack, there is danger of direct contact between
the operator's body and the work equipment. This is extremely dangerous.
If the glass is cracked, stop operations immediately and replace the glass.
