REAR OSCILLATION LOCK SYSTEM
The Rear Oscillation Lock System provides safety and
stability by preventing the frame from rotating on the
rear axle.
The rear oscillation lock will be operational when any or
all of the following conditions apply:
1. When the boom angle exceeds 40°.
2. When the service brakes are applied.
3. If a system component fails.
When the boom angle is above 40°, the following
conditions apply:
1. Rear axle cylinder locks, preventing the frame
from rotating on the rear axle.
2. Transmission is disengaged.
3. Frame tilt function is disengaged.
Note: When the frame tilt function is disengaged, it
CANNOT be overridden by the operator unless
the boom angle is below 40°.
When the service brakes are depressed, the following
conditions apply:
1. Rear axle cylinder locks preventing the frame
from rotating on the rear axle.
2. The rear oscillation lock cylinder can be unlocked
by the frame tilt function when the boom is below
40 °.
Lower the boom or release the service brake to
deactivate the rear oscillation lock system. If the system
does not deactivate, a problem exists and must be
investigated.
