• General case:
Place the vehicle on a flat, firm and stable surface. The
vehicle inclination (α) during crane operation must not be
more than 3º. If this value is exceed, unintentional crane
movements can occur.
To determine the inclination of the truck, check the spirit
level on the crane. When the bubble is in the middle of the
gauge, the crane is in horizontal position. When the bubble
is between the two circles, the crane inclination is between
0° and 5°.

• Working with boom system beyond 60°
To avoid side deflection and in order to guarantee the
safest operation when working with e.g. Lifting
Accessories and/or Hoist applications, the vehicle has
to be completely levelled in any direction (α=0º).
• Particular case 1: Working with extra load on the
vehicle platform to benefit from VSL+.
To avoid sudden movements of the vehicle and
damages on the stabiliser system, the vehicle must be
completely levelled in any direction (α=0º).
NOTE
• Operating the crane in to and out of transport position must also be done with
the vehicle completely levelled.
• Activate the parking brake and place chocks under the wheels to prevent vehicle
movement.
