Operation
12 AB60JRT
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.
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 boom slightly above horizontal.
4. Open the input connector on the chassis.
5. Allow the fluid to drain from the line.
6. Lower the boom and close both connections.
Driving Lights
The optional driving lights are for use in dimly lit areas
and are not intended for driving on public roadways.
There are two headlights at the front of the chassis and
two blinking taillights at the rear of the chassis. The lights
are operational when the battery disconnect switch and
the master switch are turned on.
Note
Working with the driving or platform work lights on, while
the engine is off, can discharge the batteries enough that
the engine will not start or the emergency power system
will not operate. If the engine cannot be left running while
the lights are on, start and run the engine for at least 15
minutes each hour
.
Platform Work Lights
The optional platform work lights are located on the top
rail of the platform. The direction a light points can be
adjusted by using two

″
wrenches to loosen the clamp
below the light.
The lights are operational when the upper controls emer-
gency stop button is pulled up and the anti-restart master
switch is turned on. The engine speed increases to high
idle when the platform work lights are turned on.
Emergency Lowering
A
Warning
If the platform should fail to lower, NEVER climb down
the elevating assembly.
Stand clear of the elevating assembly while operating
the Emergency Lowering Valve Knob.
The riser and main booms can be lowered in an emer-
gency using their respective emergency lowering knobs.
The emergency lowering knobs are at the base of the
lift cylinders. The emergency lowering knobs allow the
booms to be lowered only. Only use this method if the
engine will not start and the emergency power system
will not work.
A
Danger
Pinch points exist between boom components and
between the booms and turntable. Death or serious
injury will result if the booms or platform lowers onto
personnel. Make sure all personnel stand clear while
lowering the booms.
Riser Boom
Use the following procedure to manually lower the riser
boom.
1. Slowly turn the knob (refer to Figure 5) to open the
bleed down valve. Control the rate of descent by
turning the knob.
A
Warning
The potential for an accident increases when safety
devices do not function properly. Death or serious
injury can result from such accidents. Fully close
the emergency lowering knob before operating the
aerial platform.
2. Turn the knob to close the cylinder bleed down
valve.
