If an obstruction under the skids, or some other impairment prevents the skids from locking into position, the
driving and lifting functions will not operate and an alarm will sound.
Lower the platform and remove the obstruction when the drive/lift pothole protector interlock alarm sounds.
Drive/Lift Level Sensor Interlock
The aerial platform driving and lifting functions are interlocked through a level sensor system. The
driving/lifting level sensor interlock operates when the platform is elevated approximately 1.8 m (6′).
If the chassis is tilted more than 1.5 degrees side-to-side or more than 3 degrees front-to-rear, the driving and
lifting functions will not operate and an alarm will sound.
Lower the platform and drive to a level surface when the drive/lift level sensor alarm sounds.
The drive/lift level sensor system is for added protection and does not justify operating on anything other
than firm, flat, level surfaces.
Lowering Alarm
When the joystick is moved out of neutral to lower the platform, the alarm emits a loud beeping sound to
warn personnel in the work area to stand clear.
Danger
Pinch points exist on the scissors structure. Death or serious injury will occur if the scissors structure
lowers onto personnel within the scissors arms or under the raised platform. Stand clear while raising
and lowering the platform.
Be careful when lowering the platform. Keep hands and fingers away from the scissors structures
components.
Center the control in neutral to reset the lowering function, then continue to lower the platform.
Emergency Lowering Lever
The emergency lowering lever may be used to
lower the platform if there is a malfunction in the
hydraulic or electrical system. The lever is
mounted at the front of the aerial platform.
The emergency lowering lever may be used to
lower the scissors arms onto the safety prop before
inspecting the machine.
