Open-face technique

A = felling notch - determines the direction of the fall

For an open-face cut:

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

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

:Make second cut from below at app. 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.

B = Felling cut

Conventional and open-face technique:

:Begin 1 to 2 inches (2,5 to 5 cm) higher than centre 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

Drive wedges into the felling cut where necessary to control the fall.

!Warning!

If the tip of the bar contacts a wedge, it may cause kickback. Wedges should be of wood or plastic - never steel, which can damage the chain.
