3.1

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 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.

• Fixed pump:

Operate the stabiliser leg up for one minute in

order to warm up the oil.

• Variable pump:
