Operating conditions
You may only use the crane under the following
conditions:
• In the open air, or in spaces with sufficient
ventilation.
DANGER
• If you use the crane in a confined space
you could suffocate from the exhaust gases
from the vehicle.
• With a mean wind velocity less then 13.3
m/sec (approx. 29.7 mph).
See the wind
speed table.
• Never use the crane in a high wind or
storm. When the mean wind velocity ex-
ceeds 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 minimise wear, the crane should be started as
follows:
• Engage the power take-off at low rpm.
• Allow the system to idle for a few minutes.
• Operate the stabiliser leg up for one minute in
order to warm up the oil.
• Working with hoist in temperatures below -10
°C (14 °F) operate the hoist in both directions
without load for a few minutes to warm up
the oil.
