per quadrant of the bar nose and the chainsaw bar
jumps off the object, towards the user. Kickback may
become very dangerous for the user and therefore, be
extremely cautious when limbing and avoid contact

cautious with the limbs under tension, since they can
move backwards and towards you like a spring, which
can cause you serious injury (Fig. 14).
