Remove the leveling head strap and move the arm in order to leave
the counterweight carriage in the middle of the Fulcrum. In this position
the weights in the carriage does not affect to the balance of the crane.
In this position, check which side of the crane is heavier by slightly
loosing the rear strap with the tilt brake on and add weights in the
back/front counterweight support to balance the crane (fig. 2.52, fig.
2.53). The sliding light weight can be used to do this balance.
Once the Static Balancing has been achieved and the ratchet straps are taken off, the crane arm
can be slowly extended. When the crane becomes front heavy, stop, and add weight in the
counterweight carriage until the correct balance is achieved.
This process is repeated until the Crane Arm is at the maximum length and is balanced through its
entire length. At the end when the maximum length has been reached the smaller weights are used
to reach the correct balance.
Now the crane is ready to use all the functions in it.

Note: Be sure that the tilt brake is loose to balance the crane.
Note 2: To be more accurate, remove carefully the straps
holding the arm once is more or less balance.
Note 3: Remember to lock the weights with the counterweight
locking screw after balancing the arm.
Note: The Dynamic counterweight system can be used to
reach 100% perfect balance by changing the position of the
carriage along the movement of the crane (see chapter 4.2.3.9
CWE gen).
