Husqvarna T435 Chainsaw Owners Manual

WORKING TECHNIQUES
The directional cuts should run 1/4 of the diameter
The felling hinge controls the direction that the tree falls in.
through the trunk and the angle between the top cut and
bottom cut should be 45°.
All control over the felling direction is lost if the felling
hinge is too narrow or non-existent, or if the directional
cuts and felling cut are badly placed.
The line where the two cuts meet is called the directional
cut line. This line should be perfectly horizontal and at
right angles (90°) to the chosen felling direction.
We recommend that you use a bar that is longer than the
diameter of the tree, so that you can make the felling cut
and directional cuts with single cutting strokes. See the
Technical data section to find out which lengths of bar are
recommended for your saw.
Felling cut
The felling cut is made from the opposite side of the tree
and it must be perfectly horizontal. Try to take a correct
position so you are able to cut on the pull stroke.
Make the felling cut about 3-5 cm (1.5-2 inches) above the
bottom directional cut.
There are methods for felling trees with a diameter larger
than the bar length. However these methods involve a
much greater risk that the kickback zone of the bar will
come into contact with the tree.
Set the spike bumper (if one is fitted) just behind the felling
hinge. Use full throttle and advance the chain/bar slowly
into the tree. Make sure the tree-top does not start to
move in the opposite direction to your intended felling
direction.
WARNING! Unless you have special
training we advise you not to fell trees
with a diameter larger than the bar length
of your saw!

Freeing a tree that has fallen badly
Cutting trees and branches that are in tension
Preparations:
Work out which side is in tension and where the point of
maximum tension is (i.e. where it would break if it was
bent even more).
Finish the felling cut parallel with the directional cut line so
that the distance between them is at least 1/10 of the
trunk diameter.The uncut section of the trunk is called the
felling hinge.
Decide which is the safest way to release the tension and
whether you are able to do it safely. In complicated
situations the only safe method is to put aside your chain
saw and use a winch.
