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 steer functions will not operate.
Lower the platform and remove the obstruction when the
drive/lift pothole protector interlock is engaged.
Drive/Lift Level Sensor Interlock
The aerial platform drive and lift functions are interlocked
through a level sensor system. The drive/lift level sensor
interlock operates when the platform is elevated approx-
imately 6
′
(1.8 m).
The drive and lift functions will not operate and an alarm
will sound if the chassis is tilted more than the factory
preset level sensor value. The setting for the degree of
slope, side-to-side and front-to-rear, varies depending on
the requirements of the applicable governing body (ANSI,
CSA, CE, AS, NZS) that the machine was manufactured
to conform to.
Refer to the machines General Specifications for the drive/
lift level sensor interlock level sensor values.
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.
Progressive Tilt – S3226E Only
S3226E machines with the following serial numbers are
equipped with a progressive tilt system:
y
S3226E-04-190501073 and after
y
S3226E-01-190100398 and after
This allows the machine to be operated on greater side-
to-side slopes when the platform is below maximum rated
height. As the platform is elevated, the degree of side-to-
side slope the machine may be operated on decreases.
Refer to Figure 4.5 to determine the relationship between
platform height and degree of slope.

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 unsta
-
ble. Death or serious injury will result from a tip-over
accident. 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.
