8.5 SEGMENTS LOSS
If during the drill you notice you are losing segments or metallic parts of the crown, leave this hole and make
another drill in the same axis with a bigger diameter in 15 and 20mm.
8.6 SUDDEN DETENTION OF THE CROWN
Be cautious when you are drilling, the machine can suddenly stop. The machine has been equipped with a
mechanical clutch, but a quick action to disconnect the crown is also needed. When the crown is blocked, all parts of
the machine can suffer an overload.
Be careful and always prepared to remove the crown if it gets stuck.
To extract the crown, proceed as follows:
1.
Unplug the machine.
2.
Turn the crown with a monkey spanner by means of the hexagonal nut that worms in the axis supporting
the crown.
3.
If you do not manage with a monkey spanner, try it gently with a chain spanner around the frame.
WARNING: Do not turn the machine using the "ON" and "OFF" buttons as this can get the crown
stuck and damage the motor.
