12. OPERATION
Braking when travelling downhill
To brake the machine during downhill runs, put the travelling and
steering lever in the neutral position. This will cause the brake to be auto-
matically applied.
If shoes slip
When travelling uphill, if the shoes slip or it is impossible to travel
uphill using the force of the track only, it is possible to use pulling force of
the arm to help the machine travel uphill.
If engine stops
If the engine stops when travelling uphill, lower the bucket to the
ground, stop the machine, then start the engine again.
Precautions on slopes
• If the engine stops when the machine is on a slope, never use the left
work equipment control lever to carry out swing operations. The up-
per structure will swing under its own weight.
• 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.
