B-3 SAFETY PRECAUTIONS
■
B-3.1
JOB SITE
Always take into account the features of the job site
where you are going to work:
•
Always examine the working area and compare it
with the machine dimensions in the different
configurations.
ELECTRICAL
DANGER
Pay the greatest attention to overhead electric
lines.
Always keep at a minimum safe distance from the
telescopic boom and the lifted load. Electrical
hazards!
•
Look for the best route to the job site.
•
When the machine is running, nobody can enter
its working range.
•
While working, keep the working area in order.
Never leave objects scattered: they could hinder
the machine movements and represent a danger
for personnel.
CAUTION
Make sure the machine (wheels and stabilisers)
rests on a firm ground to prevent hazardous
unstable conditions.
If the ground is not firm enough, position some
supporting planks under the stabilisers or the
wheels. These plates must grant a specific pressure
of 1.2 to 1.5 kg/cm
2
(500x500mm plates are
sufficient).
DANGER
Do not at any time use the machine during a storm.
DANGER
DEATH OR INJURY CAN RESULT FROM
CONTACTING ELECTRIC POWER LINES.
ALWAYS CONTACT THE ELECTRIC POWER LINES
OWNER. THE ELECTRIC POWER SHALL BE
DISCONNECTED OR THE POWER LINES MOVED
OR INSULATED BEFORE MACHINE OPERATIONS
