3. Safety precautions and warnings
3.1. Operating conditions
You may use the crane ONLY if:
• You are outdoors or in a space with sufficient ventilation.
• The mean wind velocity is less than 10.7 m/sec (approx. 38 km/h or 24 mph). Refer to the wind
speed tables.
• Operational temperature range is between -20ºC and +40ºC.
DANGER
• Do not use the crane in a confined space because 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 10.7 m/sec (approx. 38 km/h or 24 mph), the crane will behave
unpredictably. Never use the crane during a thunderstorm.
• Never use the crane at temperatures below -30°C (-22°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.
• In cold weather, the wear on the hydraulic
system is greater than at normal working
temperatures.
In cold weather, start the crane as follows:
• Engage the power take-off at low rpm.
• Allow the system to idle for a few minutes.
• Operate the stabiliser legs up and down
to reach an oil temperature between 10ºC
and 15ºC. Make sure that the temperature
is between these values on the controller
display.
