Ride Control Switch (Option)

d
WARNING:
 To ensure safety, operate the ride control switch
only after parking the machine with the bucket
lowered to the ground.
 When operating the machine with the front
attachment in the float position (scooping,
grading, or snow removal), always turn the ride
control switch OFF. Failure to do so may allow the
front attachment to unexpectedly move up or
down when the ride control system is activated.
 When operating the machine with the ride control
ON, control the machine speed so as not to cause
sudden impacts to the machine. Ride control
accumulator will carry high pressure causing gas
leakage.
The ride control system dampens the vertical movement of
the front attachment during operation so that comfortable
machine ride quality is obtained. As stable drive operation
is achieved, bucket load spill can be lessened.

AUTO

When ride control switch (1) is turned to AUTO, the drive
speed sensor and the controller is activated. Then, when
the drive speed increases above the preset travel speed,
the ride control system automatically operates.
When the drive speed decreases below the preset travel
speed, the ride control system becomes inoperable.
When ride control switch (1) is turned to AUTO mode,
the ride control indicator (2) on the monitor display
comes ON.

OFF

When ride control switch (1) is turned OFF, ride control
indicator (2) on the monitor display goes OFF and the
ride control system becomes inoperable.
When the key switch is in the OFF position, the ride
control system does not operate even if ride control
switch (1) is in the AUTO position. When the engine is
stopped while ride control switch (1) is in AUTO, the ride
control is turned OFF.
