PRECAUTIONS AT Hi-SPEED TRAVEL
On uneven roadbeds such as rock beds or uneven roads with
large rocks, travel in Mi speedmode and adjust the speed of the
machine to prevent loss of control.
PRECAUTIONS WHEN TRAVELLING ON PUBLIC ROADS
When travelling or public roads the control lever pad safety lock
should be down and the control lever lock switch, in the off posi-
tion. This prevents operation of the control levers and activates
the rear facing brake lamp circuit.
PERMISSIBLE WATER DEPTH
Do not immerse the machine in water by more than the permissi-
ble depth (axle centre).
In addition, for parts that have been immersed in water for a long
time, pump in grease until the old grease comes out from the
bearings. (Around the bucket pins).
PRECAUTIONS WHEN TRAVELING UP OR DOWN HILLS
WARNING
●
When traveling, raise the bucket approx. 20 - 30 cm from
the ground.
Do not travel downhill in reverse.
●
When traveling over ridges or other obstacles, keep the
work equipment close to the ground and travel slowly.
●
It is dangerous to turn on slopes or to travel across
slopes. Always go down to a flat place to perform these
operations. It may be longer, but it will ensure safety.
●
If the machine starts to slide or loses stability, lower the
bucket immediately and brake the machine.
●
Turning or operating the work equipment when working
on slopes may cause the machine to lose its balance and
turn over, so avoid such operations. It is particularly dan-
gerous to swing downhill when the bucket is loaded.
If such operations have to be carried out, pile soil to
make platform on the slope so that the machine can be
kept horizontal when operating.
●
Do not travel on slopes of over 30° as there is danger that
the machine may overturn.
