Safe Operation
Knowledge of the information in this manual, and
proper training, provide a basis for safely operating
the TL39T. Know the location of all the controls and
how they operate to act quickly and responsibly in
an emergency.
Safety devices reduce the likelihood of an accident.
Never disable, modify, or ignore any safety device.
Safety alerts in this manual indicate situations
where accidents may occur.
If any mal function, hazard or potentially unsafe
condition relating to capacity, intended use, or safe
operationis suspected, stop the operation of the
MHP and seek assistance.
The operator bears ultimate responsibility for
following all manufacturers instructions and
warnings, regulations and safety rules of their
employer and/or any country or regional law.

Electrocution Hazards
The TL39T is an all metal boom aerial work
platform and is not electrically insulated.
Do not operate it near electrical conductors.
Regard all conductors as being energized.
Do not operate out side during a thunderstorm.
❑
Minimum safe approach distance
Minimum safe approach distances to energised
power lines and their associated parts must be
observed wile operating the MHP.

!
DANGER
The MHP is not electrically insulated. Death
or serious injury can result from contact with,
or inadequate clearance from, an energised
conductor.
Do not go closer than the minimum safe
approach distance.
ANSI publications define minimum distances that
must be observed when working near bus bars
and energised power lines. Figure 1 and Table 1
are reprinted courtesy of the Scaffold industry
Association, ANSI/SIA A92.5.

ANSI 92.5
Australian Standard AS2550.10 defines minimum
distances that must be observed when working near
live aerial conductors up to and including 133kV
(see Figure 2).
