Open-face directional notch, version B

Prepare the directional notch by sawing off any root protrusions that might complicate felling. It is often useful to cut the bark on the sides of the trunk at the level of the intended directional and felling cuts so that the cuts are clear.

Aim with the bottom cut

1. Keep the guide bar horizontal in the desired stump height.
2. Aim at a point further forward in the terrain where you want the tree to fall. The directional target must match the saw’s felling direction markings (lines).
3. Start by sawing at full throttle while checking the direction.
4. When felling thicker trees it may be necessary to supplement the top and bottom cuts from the opposite side, depending on guide bar length.
5. Saw the top cut so that it meets the bottom cut precisely. If the top and bottom cuts do not meet exactly, you will not have sufficient control over the felling.

Open-face directional notch, version B

Flat or slightly sloping terrain
Directional notch opening 45–55°
Bottom cut first, determines the direction
The bottom cut is sawn horizontally at an angle to the felling cut
Felling cut above level of directional notch
+ Low stump height
- The hinge breaks before the tree hits the ground
- Harder to see the hinge width
- Risk of splitting where the fibres in the root protrusions are asymmetric


Determine the direction
Take up position behind the saw and aim
Keep the saw and guide bar horizontal and apply full throttle
Check the direction and angle
Saw until the correct hinge length is reached
Angle the guide bar
Meet the bottom cut exactly
Move over to the other side and make the equivalent cut if the guide bar is not long enough
