1.2 Machine Description and Intended Use
Machine
description
This machine is a mobile, trailer-mounted light tower. The Wacker Neuson Light
Tower consists of a trailer with a cabinet containing a diesel engine, a fuel tank, a
control panel, and an electric alternator. A telescoping tower with four metal halide
lights is vertically mounted to the top of the machine. A hydraulic cylinder,
combined with a cable and pulley system, raises and lowers the telescoping tower.
As the engine runs, the generator converts mechanical energy into electric power.
The metal halide lights run off this power. Receptacle(s) are also provided to power
auxiliary loads. The operator uses the control panel to operate and monitor the
machine.
Intended use This machine is intended for the illumination of outdoor areas. This machine is also
intended for the purpose of supplying electrical power to connected loads. Refer to
the machine specifications for the output voltage and frequency, and for the
maximum output power limit of this Light Tower.
This machine has been designed and built strictly for the intended use described
above. Using the machine for any other purpose could permanently damage the
machine or seriously injure the operator or other persons in the area. Machine
damage caused by misuse is not covered under warranty. The following are some
examples of misuse:
Connecting a load that has voltage and frequency requirements that are
incompatible with the machine output
Overloading the machine with a device that draws excessive power during
either continuous running or startup
Operating the machine in a manner that is inconsistent with all federal, state,
and local codes and regulations
Using the machine as a ladder, support, or work surface
Using the machine to carry or transport passengers or equipment
Using the machine as a hoist, or hanging items from the tower
Operating the machine outside of factory specifications
Operating the machine in a manner inconsistent with all warnings found on the
machine and in the Operator’s Manual
This machine has been designed and built in accordance with the latest global
safety standards. It has been carefully engineered to eliminate hazards as far as
practicable and to increase operator safety through protective guards and labeling.
However, some risks may remain even after protective measures have been taken.
They are called residual risks. On this machine, they may include exposure to:
Heat, noise, exhaust, and carbon monoxide from the engine
Heat from the lights
Ultraviolet radiation from the lights
Fire hazards from improper refueling techniques
Fuel and its fumes
Electric shock and arc flash
Personal injury from improper lifting the trailer tongue

LTN 6L-V Safety Information
1.4 Lamp Safety
Description The lamps provided with your Light Tower are electric discharge lamps. They are
designed for use with metal halide ballasts only, and require time to reach full
brightness on initial startup and after a power interruption. These lamps comply
with FDA regulation performance standards 21 CFR 1040-30.
Operating
safety
Replace damaged lamps according to the instructions in section Removing /
Replacing Lamps.
Alternative lamps that automatically extinguish when the outer envelope is
broken or punctured are commercially available.
1.5 Hydraulic Fluid Safety
Safety
instructions
Inspect the hydraulic system thoroughly before operating the machine.
Do not touch hydraulic fluid or hydraulic components while the machine is
operating. Wait until the machine is cool.
Before disconnecting hydraulic fittings or hoses, ensure that all pressure has
been bled from the circuit. Set all controls in neutral, turn engine off, and allow
the fluids to cool before loosening hydraulic fittings or attaching test gauges.
Hydraulic fluid escaping under high pressure may penetrate the skin, cause
burns, blind, or cause other serious injuries or infections. Contact a physician
immediately for treatment if your skin has been penetrated by hydraulic fluid,
even if the wound seems minor.
Fluid leaks from small holes are often practically invisible. Do not use your bare
hands to check for leaks. Check for leaks using a piece of cardboard or wood.
Hydraulic fluid is extremely flammable. Stop the engine immediately if a
hydraulic leak is detected.
After servicing the hydraulics, make sure all components are reconnected to the
proper fittings. Failure to do so may result in damage to the machine and/or
injury to a person on or near the machine.
1.6 Service Safety
WARNING
Personal injury hazard. Broken or punctured lamps can cause serious skin burns
and eye inflammation from shortwave ultraviolet radiation.
"Do not operate the Light Tower if a lamp is damaged.
fReplace damaged lamps immediately.
WARNING
