MACHINE OPERATIONS AND CONTROLS MACHINE OPERATIONS AND CONTROLS
When traveling up a steep slope, extend the work equipment to
the front to improve the balance, keep the work equipment
approximately 20 to 30 cm (8 to 12 in) above the ground, and
travel at low speed.
Traveling Downhill
Put the travel lever in the neutral position. This will cause the brake to be automatically applied.
Engine Stopped on Slope
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.
Cab Doors on Slope
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 upper structure will swing under its own weight.
Do not open or close the door when the machine is on a slope. The operating effort may suddenly change.
Always keep the door locked in position when it is open and when it is closed.
