- Safety precautions
N.B.
-:-The Beaufort scale measures the wind force with a graduation system. A wind speed range at 10
m(32 ft9 in) above flat, clear land is associated with each degree.
Beaufort scale
• Do not drive the machine on slopes or tilts beyond the design limits. Check the maximum value in the
technical characteristics(
Section G 1-Main characteristics).
• Do not travel down slopes at high speed.
• Do not use the machine (elevation and travel) on an incline greater than that permitted by the slope
sensor.
• Do not drive in reverse (direction opposite the field of vision).
• Never use the machine in winds exceeding the permissible limit.
• Do not increase the surface area exposed to wind. The greater the surface area exposed, the more
unstable the machine becomes.
• While driving, always place the arrow above the rear axle, in the direction of movement.
• While driving on a slope, always orient the machine in the direction of the slope.
• Do not pull or push objects with the boom.
