INSIDE BEND

CUTS

(ONE INCH APART)

1.Position yourself inside the bend.

2.Start a V-cut on your side, inside the bend. Cut up to 1/4 of the diameter of the trunk, taking care that the saw does not jam.

3.Remaining on the inside of the bend, move the saw over to the opposite side.

4.Cut slowly to reduce tension.

IMPORTANT!

To avoid jamming the saw, a V-cut is recommended for the first cut. Make it in small increments, as illustrated, to permit the tree to break slowly, giving you time to back out of the way.

Small Trees and Limbs Under Tension.

1.Always stay on the inside of the bend.

2.Make your cut at the breaking point.

3.If possible, cut along the tree/limb.

4.Cut slowly to relieve tension.

CAUTION!

Stay clear of tree/limb path.

5.If you must cut across tree/limb, make two to three cuts, one inch apart one to two inches deep.

6.Continue to cut deeper until tree/limb bends and tension is released.

7.Cut tree/limb from outside the bend, after tension has been released.
