7 Proper Techniques for Basic Bucking, Limbing, Pruning and Felling English C C ► The felling notch determines the direction of the tree's fall. Make the felling notch perpen‐ dicular to the line of fall you have determined, close to the ground. ► Be aware of conditions such as wind, limb and foliage structure, tree lean, the slope of the terrain and other factors that could alter the direction of fall. ► Cut down at a 45° angle to a depth of approxi‐ mately 1/5 to 1/4 of the trunk diameter. 0000-GXX-1438-A1 ► The felling notch determines the direction of the tree's fall. Make the felling notch perpen‐ dicular to the line of fall you have determined, close to the ground. ► Be aware of conditions such as wind, limb and foliage structure, tree lean, slope of the terrain and other factors that could alter the direction of fall. ► Cut down at a 50° angle to a depth of approxi‐ mately 1/5 to 1/4 of the trunk diameter. ► Make a second cut that meets the bottom of the first cut from below at a 40° angle. ► Remove the resulting 90° piece. The size of the wedge will vary by tree size. The larger the tree, the larger the wedge. 7.5.5 Sapwood Cuts Sapwood cuts help prevent soft woods in sum‐ mer from splintering when they fall: 1 0000-GXX-1250-A1 0000099377_001 When making the notch, use the gunning sight (1) on the saw to check the desired direc‐ tion of fall: ► Place the felling notch perpendicular to the line of fall. Position the saw so that the gun‐ ning sight (1) points exactly in the direction you want the tree to fall. ► Make a horizontal cut that meets the bottom of the first cut. ► Remove the resulting 45° piece. The size of the wedge will vary by tree size. The larger the tree, the larger the wedge. 7.5.4 Open-faced Notch For an open-faced notch: C C 0000-GXX-1439-A1 ► Make cuts at both sides of the trunk, at the same height as the subsequent felling back cut. ► Cut no deeper than the width of guide bar. 7.5.6 Felling Back Cut WARNING ■ If the tip of the bar contacts a wedge that has been used to help keep the kerf or cut open, it may cause kickback. Wedges should be of wood or plastic and never steel, which can damage the chain. ■ Whichever felling method you select, never cut through the hinge when making your felling back cut. The hinge helps control the fall of the tree. Cutting through the hinge will eliminate the feller's ability to control the tree's fall and may result in serious or fatal personal injury or property damage. ■ In order to reduce the risk of personal injury, never stand directly behind the tree when it is about to fall, since part of the trunk may split and come back towards the operator (barberchairing), or the tree may jump backwards off the stump. 0458-221-8621-A 23

►

The felling notch determines the direction of

the tree's fall. Make the felling notch perpen‐

dicular to the line of fall you have determined,

close to the ground.

►

Be aware of conditions such as wind, limb and

foliage structure, tree lean, the slope of the

terrain and other factors that could alter the

direction of fall.

►

Cut down at a 45° angle to a depth of approxi‐

mately 1/5 to 1/4 of the trunk diameter.

0000099377_001

When making the notch, use the gunning

sight (1) on the saw to check the desired direc‐

tion of fall:

►

Place the felling notch perpendicular to the

line of fall. Position the saw so that the gun‐

ning sight (1) points exactly in the direction

you want the tree to fall.

►

Make a horizontal cut that meets the bottom of

the first cut.

►

Remove the resulting 45° piece. The size of

the wedge will vary by tree size. The larger the

tree, the larger the wedge.

Sapwood Cuts

Sapwood cuts help prevent soft woods in sum‐

mer from splintering when they fall:

0000-GXX-1250-A1

►

Make cuts at both sides of the trunk, at the

same height as the subsequent felling back

cut.

►

Cut no deeper than the width of guide bar.

7.5.6

Felling Back Cut

WARNING

■

If the tip of the bar contacts a wedge that has

been used to help keep the kerf or cut open, it

may cause kickback. Wedges should be of

wood or plastic and never steel, which can

damage the chain.

■

Whichever felling method you select, never cut

through the hinge when making your felling

back cut. The hinge helps control the fall of the

tree. Cutting through the hinge will eliminate

the feller's ability to control the tree's fall and

may result in serious or fatal personal injury or

property damage.

■

In order to reduce the risk of personal injury,

never stand directly behind the tree when it is

about to fall, since part of the trunk may split

and come back towards the operator (barber-

chairing), or the tree may jump backwards off

the stump.
