WARNING: Failure to follow these safety
precautions may lead to a serious accident.
VENTILATION FOR ENCLOSED AREAS
• If it is necessary to start the engine within an enclosed area,
provide adequate ventilation. Exhaust fumes from the engine can KILL.
PRECAUTIONS FOR MIRRORS, WINDOWS AND LIGHTS
• Remove all dirt from the surface of the windows and lights to ensure that you can see well.
• Adjust the rear view mirror so that you can see clearly from the operator's seat, and always keep the surface
of the mirror clean. If any glass is broken, replace it with a new part.
• Check that the head lamps and working lamps are installed to match the operating conditions. Check also
that they light up properly.
PRECAUTIONS WHEN HANDLING (TWO PIECE BOOM)
When operating the boom arm 2-piece type, select a specialist operator and do not allow any other
person to operate the machine.
• Check that the ground inside the operating range is flat and firm.
• Always operate the work equipment slowly.
Especially when lowering the work equipment, move it as slowly as possible to prevent any
shock to the machine (operate the work equipment in the same way as when operating a crane).
• Pay attention to warning decal in the cab. (A copy is shown at the bottom of this page)
If the bucket is operated in a certain way, it comes in contact with the machine body (operator's
cab, upper boom, cylinders and undercarriage). When operating the work equipment, take suf-
ficient care not to bring it in contact with the machine body.
