Braking when traveling downhill
To brake the machine during downhill runs, put the travel lever in
the neutral position. This will cause the brake to be automatically
applied.
If shoes slip
When traveling uphill, if the shoes slip or it is impossible to travel
uphill using the force of the track only, it is possible to use the pulling
force of the arm to help the machine travel uphill.
If engine stops
If the engine stops when traveling uphill, move the travel levers to
the neutral position, lower the bucket to the ground, stop the
machine, then start the engine again.
Precautions on slopes
l
If
the engine stops when the machine is on a slope, never use
the left work equipment control lever to carry out swing opera-
tions. The upper structure will swing under its own weight.
l Do not open or close the door on the cab if the machine is on
a slope. This may cause a sudden change in the operating force.
Always keep the door locked.
