WORKING TECHNIQUES
Remove any undergrowth from the base of the tree and check the area for obstacles (stones, branches, holes, etc.) so that you have a clear path of retreat when the tree starts to fall.
Your path of retreat should be roughly 135 degrees away from the intended felling direction.
The directional cuts should run 1/4 of the diameter through the trunk and the angle between the top cut and bottom cut should be 45°.

Felling
WARNING! Unless you have special training
!we advise you not to fell trees with a diameter larger than the bar length of your saw!
Felling is done using three cuts. First you make the directional cuts, which consist of the top cut and the bottom cut, then you finish with the felling cut. By placing these cuts correctly you can control the felling direction very accurately.
Directional cuts
To make the directional cuts you begin with the top cut. Stand to the right of the tree and cut on the pull stroke.
Next make the bottom cut so that it finishes exactly at the end of the top cut.
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.
Felling cut
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
Set the spike bumper (if one is fitted) just behind the felling hinge. Use full throttle and bring the bar and chain 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.
