Operation
AB46E – 0260229 11
Always look in the direction of movement as indicated
by the directional arrows on the chassis.
Use the following procedure to operate the drive and
steer functions.
1. Determine the desired drive range for the specific
driving conditions. Place the switch in the appropriate
position to achieve the desired drive wheel opera-
tion.
Use high range (rabbit) when traveling across fi rm,
fl at, level surfaces. High range can only be activated
when the booms are stowed. High range is for high
speed, low torque operation.
Use low range (turtle) for driving on loading ramps or
other steep grades and when safety considerations
demand slow deliberate machine movement. Low
range is for low speed, high torque operation.
2. Step down on the platform foot switch.
3. Push the drive joystick forward to move the chas-
sis forward, the direction of the blue arrow. Pull the
joystick backward to move the chassis backward,
the direction of the yellow arrow. The drive speed is
proportional to the joystick position.
4. To stop drive motion, return the joystick to neutral.
5. The steer switch is a momentary contact, rocker
switch on top of the drive joystick. The switch controls
the two front wheels to steer the aerial platform.
To steer to the right, hold down the right side of the
steer switch.
To steer to the left, hold down the left side of the
steer switch.
Note
The steering wheels are not self-centering. Set the steer-
ing wheels straight ahead after completing a turn.
6. After driving to the desired location, release the foot
switch, or push the emergency stop button to apply
the parking brakes.
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 and shift the drive system to low range
before traveling over any sloped surface.
Drive speed ranges are interlocked through limit switches
that sense the main and riser boom position.
When either boom is elevated or extended, only the
slowest drive speed will work regardless of the drive
range switch position.

To avoid a sudden speed change from high to low
elevated boom speed, always bring the machine
to a stop before raising the booms from the stowed
position.
A
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
1.3 km/h (.8 miles per hour) [15.24 m (50 feet) in 42.5
seconds] when any of the booms are out of the stowed
position.
All Motion Alarm
The optional all motion alarm sounds loud intermittent
beeps anytime the machine functions are being oper-
ated.
Electrical Power Outlet
The electrical outlet at the platform has two, 3-prong, 110
volt AC electrical connectors. Their combined output is
limited by a 15 amp circuit breaker.
To use the outlet, plug a source of power into the power-
input connector on the right side of the chassis. Unplug
the source of power before moving the aerial platform.
Air Line
The optional air line may be used to conduct air for tool
operation at the platform.
The input connector is at the rear of the chassis and
the output connector is at the platform on the rotator
guard.
The maximum working pressure of the line is
1,723 kPa (250 psi).
The air line may be used to conduct fluids such as water or
antifreeze. Contact UpRight for compatibility information
before using the air line to conduct other fluids.
A
Caution
Fluid in the air line may damage some air tools or
freeze and damage the line. Drain and blow out the
air line after using it to conduct fluids.
Use the following procedure to drain the air line.
1. Close the input connector on the chassis.
2. Open the output connector at the platform.
3. Raise the riser and main booms slightly above hori-
zontal.
4. Open the input connector on the chassis.
