WARNING
Care must be taken when handling loads in
the high lifting area, so the load/tool does not
come into contact with the boom system.
3.5. Operating conditions
You may only use the crane under the following conditions:
• In the open air, or in spaces with sufficient ventilation.
• With a mean wind velocity less than 13.3 m/sec (approx. 29.7 mph).
See the wind speed table.
DANGER
• If you use the crane in a confined space you could suffocate from the exhaust
gases from the vehicle.
• Never use the crane in a high wind or storm. When the mean wind velocity
exceeds 13.3 m/sec (approx. 29.7 mph) the crane will behave unpredictably.
Never
use the crane during a thunderstorm.
•
Never
use the crane at temperatures below -40°C (-40°F), as the steel's
properties deteriorate below this temperature.
WARNING
• At temperatures below 0°C (32°F):
Do
not
touch the operating levers during
the first few minutes.
• When starting in cold weather, the wear on
the hydraulic system is greater than at
normal working temperatures.
To get a good function of the crane, it should
be started as follows:
• Engage the power take-off at low rpm.
• Allow the system to idle for a few minutes.
• Operate stabiliser legs up and down for
one minute, in order to warm up the oil.
