MOVING THE MACHINE
Precautions for Driving on Slopes
d
WARNING:

Never allow the machine to descend a slope with
the forward/reverse lever in neutral (N). This will
not only cause the excessive engine revolutions
to malfunction but also cause other engine and
machine troubles.

When descending a slope, use normal resistance
to travel as exerted by the engine through the
drive train. Apply the brakes only when absolutely
required. If the brake is continuously used while
descending a slope, the brake temperature will
increase, possibly decreasing braking performance.
If overheating of the brake system is noticed,
immediately park the machine in a safe location.
Restart and operate the machine only after the
brake system is sufficiently cooled.

When descending a slope, do not operate 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 loader front to increase
the machine stability. Do not steer on a steep slope since this
may cause the machine to turn over.
When descending a slope, descend in a low drive range with
engine resistance applied.
Do not operate the machine at a speed faster than the
maximum travel speed.
In case the engine stalls on a slope, immediately step on the
service brake pedal, lower the loader arms 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 engine, return the
Forward/Reverse lever to neutral (N) and turn the parking
brake switch ON.

Before descending a slope, confirm that the service and
parking brake systems work normally.

In case the hydraulic oil and lubricant temperatures
are low, the machine gradability may decrease. Before
climbing a steep slope, warm up the machine.
