8Unless the user resists this pushing force there is a risk 
that the chain saw will move so far backwards that only 
the kickback zone of the bar is in contact with the tree, 
which will lead to a kickback. 
(36)Cutting with the bottom edge of the bar, i.e. from the top 
of the object downwards, is known as cutting on the pull 
stroke. In this case the chain saw pulls itself towards the 
tree and the front edge of the chain saw body rests...
