7  Installation

7-1   Balancing  

During applications involving the use of heavier heads models, the return spring of the drill 
could not able to support the weight of the head and, therefore, the spindle will tend to lower 
itself.
In this case, it is necessary to execute a system to solve this problem.
In case of doubts, the MPA technical department is always at your disposal.
