For an open-face cut:

:Properly place felling notch perpendicular to the line of fall, close to the ground.

:Cut down at approx. 50-degree angle to a depth of approx.1/5 to 1/4 of the trunk diameter.

:Make second cut from below at approx. 40 degree angle.

:Remove resulting 90-degree piece.

Making sapwood cuts

:For medium sized or larger trees make cuts at both sides of the trunk, at same height as subsequent felling cut.

:Cut to no more than width of guide bar.

This is especially important in softwood in summer - it helps prevent sapwood splintering when the tree falls.

D = Felling cut

Conventional and open-face technique:

:Begin 1 to 2 inches (2,5 to 5 cm) higher than center of felling notch.

:Cut horizontally towards the felling notch.

:Leave approx.1/10 of diameter uncut. This is the hinge.

:Do not cut through the hinge - you could lose control of the direction of the fall.
