A = Direction of fall
B = Escape paths
– Establish paths of escape for
everyone concerned – opposite to
direction of fall at about 45°.
– Remove all obstacles from escape
paths.
– Place all tools and equipment a safe
distance away from the tree, but not
on the escape paths.
– Always keep to the side of the falling
tree. When the tree starts to fall,
withdraw the bar, shut off the engine
and walk away on the preplanned
escape path.
– On steep slopes, prepare escape
paths parallel to the slope.
– Watch out for falling limbs and pay
attention to crown.
Preparing work area at base of tree
– First clear the tree base and work
area from interfering limbs and
brush – safe footing for all persons
concerned.
– Clean lower portion of tree base
with an axe. Sand, stones and other
foreign objects will dull the saw
chain.
– Remove large buttress roots: Make
vertical cut first, then horizontal –
but only if tree is in sound condition.
Making felling notch
When making the felling notch, make
use of the gunning sight on the shroud
and fan housing to check the planned
direction of fall.
Position your saw so that the gunning
sight points in exactly in the direction
you want the tree to fall.
There are several permissible ways of
making the horizontal and angled cuts –
observe country-specific regulations on
felling techniques.
