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 dangerous 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.
