PRECAUTIONS FOR BLADE POSITION DURING BACKHOE OPERATION

When performing the backhoe operation near the blade, take
care that the boom cylinder does not touch the blade. Dig with
the blade at the rear usually, and dig in front of the blade only
when required.

PRECAUTIONS FOR OPENING AND CLOSING COVERS

Close all the covers and lock the lockable covers when operat-
ing or driving the machine.
If you operate the machine with the cover open, it may hit
something around it and break.
If you operate or drive the machine with cover unlocked, it may
open and hit surrounding object to lead accident.

PERMISSIBLE DEPTH OF WATER, SOIL AND DIRT

NOTICE
When traveling the machine out of water, if the angle of the
machine exceeds 15 °, the rear of the upper structure will
go under water, and water will be thrown up by the radiator
fan, This may cause the fan to break. Be extremely careful
when driving the machine out of water.

Do not drive the machine in water or soil and dirt deeper than
the center of carrier roller (1).
After the job, be sure to supply grease to the parts which have
been under water for a long time until the used grease is pro-
jected. (Around the bucket pin, in particular)
