Operation
SB66JRT 11
To avoid confusion, always drive to the work area or
move between work areas with the turntable and booms
in the stowed position. After arriving at the work area, the
booms may be positioned to the side or the front of the
chassis for final positioning. 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.
Use high range 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 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. Place the drive/boom selector switch in the drive
position.
3. Step down on the platform foot switch.
4. 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.
5. To stop drive motion, return the joystick to neutral.
6. Push the drive joystick to the right to steer to the right,
the direction of the yellow arrow. Push the joystick
to the left to steer to the left, the direction of the blue
arrow.
Note
The steering wheels are not self-centering. Set the steer-
ing wheels straight ahead after completing a turn.
7. 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 rough terrain or any sloped
surface.
Drive speed ranges are interlocked through a limit switch
that senses the main boom position. When the boom is
elevated, only the slowest drive speed will work regard-
less of the drive range switch position.

A
Warning
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 0.96
km/h (0.6 miles per hour) [7.9 m (26 feet) in 30 seconds]
when the booms are elevated from the stowed position.
Motion Warning Alarm
The optional motion warning alarm sounds loud intermit-
tent beeps when the drive joystick is in the forward or
reverse position.
AC Generator
The optional generator supplies power to the electrical
outlet only when the engine is running and the machine
is stationary. The machine functions will not operate when
the machine/generator selector switch is in the generator
position.
A
Caution
Cold hydraulic oil does not flow well and may produce
improper generator output voltage. Improper outlet
voltage can damage some electrical power tools and
equipment. Warm the hydraulic oil before operating
the generator.
Do not operate the generator unless the hydraulic oil tem-
perature is at least 38°C (100°F). Refer to Cold Weather
Start-Up for a hydraulic oil warm-up procedure.
Start the engine and place the machine/generator se-
lector switch in the generator position (ref: Figure 4 on
page 6).
The engine will run at high idle while the generator is
operating. The generator will continue to operate as long
as the engine is running and the switch is in the genera-
tor position.
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 your local distriburor or UpRight
for compatibility information before using the air line to
conduct other fluids.
A
Caution
Fluid in the air line can damage some air tools or
freeze and damage the line. Drain and blow out the
air line after using it to conduct fluids.
