TB42J – 0172310 45
Do not use the aerial platform if it drives faster than 1.0
miles per hour (50 feet in 33 seconds) when the booms
are elevated from the stowed position.
Motion Warning Alarm
The motion warning alarm sounds loud intermittent beeps
when the drive joystick is in the forward or reverse posi-
tion.
Four Wheel Drive
The machine may be equipped with a four wheel drive
system. This system operates full time and requires no
action by the operator.
Four wheel drive machines have a “4x4” decal on each
side of the machine and all four of the wheel hubs are
drive hubs and look the same.
Electrical Power Outlet
The electrical outlet at the platform has 2, 3-prong, 125
volt AC electrical connectors. Their combined output is
limited by a 15 amp circuit breaker.
Power may be supplied to the outlet using an external
power source or by operating the optional AC generator.
To use the outlet, plug a source of power into the power-
input connector on the left side of the lower control panel
(refer to Figure 8.6). Unplug the source of power before
moving the aerial platform.

AC Generator
The generator can be used to supply power to the electri-
cal outlet only when the engine is running and the ma-
chine is stationary. The machine functions will not oper-
ate when the machine/generator selector switch is in the
generator position.
A
Caution
Cold hydraulic oil does not flow well and may pro-
duce improper generator output voltage. Improper
outlet voltage can damage some electrical power
tools and equipment. Warm the hydraulic oil be-
fore operating the generator.
Do not operate the generator unless the hydraulic oil tem-
perature is at least 100°F (38°C). Refer to Cold Weather
Start-Up for a hydraulic oil warm-up procedure.
Use the following procedure to supply power to the elec-
trical power outlet if the machine is equipped with the
optional generator.
1. Plug the generator cord into the outlet on the left
side of the lower control panel.
2. Start the engine and place the machine/generator
selector switch on the front of the upper control panel
in the generator position.
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.
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 sys-
tem 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
1 /
2
″ 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 mas-
ter switch is turned on.
The engine speed increases to high idle when the plat-
form work lights are turned on.
