DESCENDING AND ASCENDING INCLINES
Always use the brake pedal to help slow the
machine to 16 km/h (10 mph) when descending
inclines with grades greater than 10%. The drive
motor does slow the machine when the
accelerator is released, but should not be used
alone to slow the machine when descending hills.
The drive motor could overheat and shut
down if the brake pedal is not also used to
slow the machine on declines.
Do not drive the machine on ascents with grades
greater than 20%. The drive motor could overheat
and shut down if the machine is operated on
ascents greater than 20%.
A yellow bar appears at the top of the MD3
machine management system display when the
machine drive motor is operating at normal
temperatures. The bar changes to red when the
drive motor temperature reaches 85

The machine will begin slowing when the drive
motor temperature reaches 85
_
C (185
_
F) and
continue slowing as the drive motor temperature
rises. The machine will come to a complete stop
when the drive motor temperature reaches 118
_
C
(244
_
F).
A warning appears on the MD3 machine
management system display when the drive motor
begins overheating.
