PRECAUTIONS FOR HIGH SPEED TRAVEL
On uneven roadbeds such as rock-beds or uneven roads with large rocks, drive the machine at Lo-speed.
When driving the machine at Hi-speed, set the idler in the traveling direction.
Each time the travel speed selector switch (1) is pressed, the
travel speed changes repeatedly as Lo → Hi → Lo. The travel
speed (Lo, Hi) is displayed on travel speed display (2).
PRECAUTIONS WHEN PERFORMING OPERATIONS CONTINUOUSLY WITH THE
WORK EQUIPMENT IN THE SAME POSTURE
If the cylinder has been operated in small strokes continuously, operate it largely once in a while for greasing the
work equipment pin portion in order to prevent running out of grease at that portion.
PERMISSIBLE DEPTH OF WATER, SOIL AND DIRT
NOTICE
When driving 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 cooling
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 or sand deeper than
the centre of upper 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)
