Precautions for Driving on Slopes

d
WARNING:
 Never allow the machine to descend a slope with the
forward/reverse lever in neutral (N). Failure to do so
will not only work the engine braking to malfunction
but also create the causes of various machine
troubles.
 When descending a slope, use engine braking.
Apply the brakes only when absolutely required. If
the brake is continuously used while descending a
slope, the brake temperature will increase, possibly
decreasing the braking performance.
If overheating of the brake system is recognized,
immediately park the machine in a safe location.
Restart and drive the machine only after the brake
system is sufficiently cooled.
 When descending a slope, do not drive the machine
at a speed faster than the maximum travel speed.
Failure to do so may damage the machine and/or a
serious accident may result.
When steering on a slope, lower the bucket to increase the
machine stability. Do not steer on a steep slope. Failure to do
so may possibly cause the machine to turn over.
When descending a slope, travel the machine in the slow drive
gear range using sufficient engine braking.
Do not drive the machine at a speed faster than the maximum
travel speed.
If the engine stalls on a slope, immediately step on the
brake pedal as strongly as possible, lower the loader front
to the ground and stop the machine. The parking brake is
automatically applied when the engine is stopped regardless
of the position of the parking brake switch. Before restarting
the engine, return the Forward/Reverse lever to neutral (N)
and turn the parking brake switch ON.
 Before descending a slope, confirm that the brake system
works normally by operating the brake pedal.
 If the hydraulic oil and lubricant temperatures are low, the
machine gradeability may decrease. Before climbing a
steep slope, sufficiently perform the warm up operation
of the machine.
