Another open face directional notch felling technique

Find another open face directional notch felling technique.

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. 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

• 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

    Limbing thick branches

    A different work technique is used for limbing thick branches than that used for thin branches. This applies to leaf trees and other trees with thick, extensive branches. The working technique often matches the technique used for crosscutting. In order to avoid splitting and the guide bar pinching, it is important that you use the correct technique and sequence.

  • Usage


    Consider the crosscutting carefully, especially for larger logs. An incorrect work technique can be dangerous and cause the trunk to split or the guide bar to become pinched. First assess the tension in the trunk. Make it a habit to look at how the trunk reacts to being cut. You may have misjudged the tension.
