Drive speed ranges are interlocked through a limit switch that senses scissors arm position. When the
platform is elevated below approximately 1.8 m (6
′
), the aerial platform may be driven within the full
range of drive speeds. Above 1.8 m (6
′
) of elevation, only the slowest drive speed will work.
Danger
The potential for an accident increases when safety devices do not function properly. Death or serious
injury can result from such accidents. Do not alter, disable, or override any safety device.
Do not use the aerial platform if it drives faster than 0.6 km/h (0.4 mph), which is 5.3 m (17
′
7
″
) in 30
seconds, when elevated above 1.8 m (6
′
) even if the joystick is in the mid or high speed position.
Drive/Lift Level Sensor Interlock
If the chassis is tilted more than 1.5 degrees side-to-side or more than 3 degrees front-to-rear, platform raise
and drive functions are disabled and an alarm sounds when those controls are activated.
If the drive/lift level sensor interlock shuts off the platform raise and drive functions, lower the platform and
drive to a level surface.
Platform raise and drive functions may also be disabled by the pothole protection interlock.
Steering
The steer control switch is located on the joystick. Use the following procedure to steer the aerial platform
using the upper controls.
1.
Squeeze and hold the interlock switch against the joystick
•
To turn to the left, tap lightly on the left side of the steer switch.
•
To turn to the right, tap lightly on the right side of the steer switch.
Note
Holding the steer switch down too long may result in a sharp turn. This is especially true when driving and
steering at the same time. It may be easier to turn the wheels in small increments using a series of quick taps
on the steer switch.
2.
Set the steer wheels straight ahead after completing a turn. The steering wheels are not
self-centering.
Platform
Use care when entering and exiting the platform to avoid slipping and/or falling. Fully lower the gravity gate
when the platform is occupied.
Danger
The potential for an accident increases when the swing-down rails are lowered. Death or serious
injury can result from such accidents. Do not elevate the platform with the swing-down rails lowered.
Be sure the swing-down rails are up and the pins are all installed, anytime the machine is not being
transported.
Raising and Lowering
The raise speed is proportional to the joystick position. The farther the joystick is moved, the faster the
platform raises. There is only one lowering speed.
