Ride Control Switch (Optional) - Hitachi ZW180 Operator's Manual

RIDE CONTROL SWITCH (OPTIONAL)

Damps the vertical vibration of the front attachment during
drive operation so that comfortable machine ride quality is ob-
tained. As stable drive operation is achieved, bucket load spill
can be reduced.
WARNING: Do not turn ride control switch (6) ON
while driving the machine or raising the front attach-
ment. As soon as the switch is turned ON, the hydrau-
lic pressure oil is routed to the lift cylinder bottom
circuit from the accumulator, causing the front attach-
ment to move. Thereby, the machine stability may be
reduced. Especially, never turn the switch ON when
inspecting the machine. Failure to do so may result in
personal injury or death.
WARNING: When operation the machine with the
front attachment in the float position (scooping,
grading, or snow removal), always turn the ride con-
trol switch OFF. Failure to do so may allow the front
attachment to unexpectedly move up or down when
the ride control system is activated.
Ride Control Operation
WARNING: To ensure safety, operate ride control
switch (6) only after parking the machine with the
bucket lowered to the ground.
When the switch (6) is turned ON, the drive speed sensor and
the controller is activated. Then, when the drive speed be-
comes faster than 5 km/h, the ride control system automati-
cally operates. When the drive speed becomes slower than 3
km/h, the ride control system becomes inoperable. When the
switch (6) is turned ON, the monitor indicator (25) comes ON.
When the switch (6) is turned OFF, the monitor indicator (25)
goes OFF so that the ride control system becomes inoperable.
When the ignition switch is in the OFF position, the ride con-
trol system does not operate even if the ride control switch is
turned ON.
