interlock operates when the platform is elevated approxi-
mately 6′ (1.8 m).
If the chassis is tilted more than one and a half degrees side-
to-side or more than four degrees front-to-rear, the drive and
lift 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 result 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.
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 (refer to Figure 4.5).
Figure 4.5 – Front of Machine
Danger
Pinch points exist on the scissors structure. Death or
serious injury will result if the scissors structure low-
ers onto personnel within the scissors arms or under
the raised platform. Stand clear while operating the
emergency lowering lever to lower the platform.
Drive Motion Alarm
When the joystick is moved out of neutral to drive the
aerial platform, the alarm emits a loud beeping sound to
warn personnel in the work area to stand clear.
Pothole Protector Skids
The pothole protector skids automatically lower when the
platform is elevated approximately 24″ (61 cm). Ground
clearance is reduced from 2.63″ (6 cm) to 3/4″ (1.9 cm)
when the skids lock into position (refer to Figure 4.4).

Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over ac-
cident. Do not drive or position the aerial platform for
elevated use within 4′ (1.2 m) of any drop-off, hole, or
other tip-over hazard.
This protection system limits the tilt angle if a wheel is
driven into a drop-off or hole. This greatly reduces the
likelihood of the aerial platform tipping over.
The pothole protection system is for added protection and
does not justify operating near drop-offs or holes.
Drive/Lift Pothole Protector Interlock
The aerial platform drive and lift functions are interlocked
through a limit switch that senses whether or not the
pothole protection linkage is locked into position. The
drive/lift pothole interlock operates when the platform is
elevated approximately 6′ (1.8 m).
If an obstruction under the skids, or some other impair-
ment prevents the skids from locking into position, the
drive and lift 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 drive and lift functions are interlocked
through a level sensor system. The drive/lift level sensor
