Drive Speeds
The drive speed is proportional to the joystick position. The
farther the joystick is moved, the faster the travel speed.
Always slow down before traveling over rough terrain or
any sloped surface.
Drive speed ranges are interlocked through limit switches
that sense the platform position.
y
When the platform is elevated below approximately
6
′
(1.8 m) the aerial platform may be driven with the
full range of drive speeds.
y
When the platform is elevated above 6
′
(1.8 m) only
the slowest drive speed will work.
Warning
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury could result from such accidents. Do not alter,
disable, or override any safety device.
Do not use the aerial platform if it drives faster than 0.4
mph (0.6 km/h), which is 7
′
7
″
(5.3 m) in 30 seconds,
when elevated above 6
′
(1.8 m).
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
When the platform is elevated above 6
′
(1.8 m), drive
and lift functions are interlocked through a level sensor
system.
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.
If the drive/lift level sensor interlock shuts off the platform
raise and drive functions, lower the platform and drive to
a level surface.

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.
Figure 9.4 – Progressive Tilt
Swing-Out Trays
Batteries and hydraulic components are enclosed in
swing-out trays (refer to Figure 9.5) on each side of the
chassis.
Figure 9.5 – Swing-Out Trays
y
The battery trays each contain two batteries. There is
a battery tray at the front of the machine, both sides
of the chassis.
y
The control valve tray on the right side of the chassis
contains the hydraulic control valve with the free-
wheeling valve, brake release valve and the brake
hand pump. The diagnostic center LCD display is
also in this tray.
