Starting operations
Placing the vehicle
•
General case:
Place the vehicle on a flat and firm surface. The
vehicle inclination during crane operation must
not be more than allowed in the Technical
Data for your crane
.
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°.
If the slope exceeds the permitted inclination,
unintentional crane movements can occur.
•
Particular case: Working with boom sys-
tem beyond 60°
To avoid side deflection and in order to
guarantee the safest operation when working
with e.g. hoist applications, the vehicle has to
be completely levelled in any direction.
! NOTE
• Operating the crane in to and out of parking
position must also be done with the vehicle
completely levelled.
• Activate the parking brake and place chocks
under the wheels to prevent vehicle move-
ment.
PTO
• Engage the PTO (Power Take Off).
• Bring the vehicle's engine to the correct rpm.
! NOTE
• Rpm too high: the oil in the hydraulic system
might overheat. Rpm too low: during crane
operation, the vehicle's engine could stall.
• The maximum rpm may depend upon a
governor on your PTO combination.
