The felling cut is made from the opposite side of the tree 
and it must be perfectly horizontal. Stand on the left side 
of the tree and cut on the pull stroke.

Make the felling cut about 3-5 cm (1.5-2 inches) above the 
bottom directional cut.

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 does not start to 
move in the opposite direction to your intended felling 
direction. Drive a wedge or breaking bar into the cut as 
soon as it is deep enough.

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.

The felling hinge controls the direction that the tree falls in.

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.

When the felling cut and directional cut are complete the 
tree should start to fall by itself or with the aid of a felling 
wedge or breaking bar.

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 
instructions under the heading Technical data section to 
find out which lengths of bar are recommended for your 
saw.

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.

It is very dangerous to remove a trapped tree and there is 
high accident risk.

Never try to fell the tree that is trapped.

Never work in the risk zone of the hanging trapped tree.

The safest method is to use a winch.
