Check for the correct belt tension by exerting a light pressure with your fingers.
Belt tension
It is very important that the belts are under tension, in order not to compromise the efficiency
of the Drill.

It is very important that the bolts (2) touch against the rear part of the head so that
the motor lays there.
If the motor is not supported on its lower side too, the machine may produce excessive
noise and vibration.
