Cut

When the log is supported on both ends (Fig. 14),

cut 1/3 the diameter from the top (overbuck). Then

make the finished cut by underbucking the lower

2/3 to meet the first cut.

When bucking on a slope always stand on the up

hill side of the log (Fig. 15). When cutting through,

to maintain complete control, release the cutting

pressure near the end of the cut without relaxing

your grip on the chain saw handles. Don’t let the

chain contact the ground. After completing the cut,

wait for the saw chain to stop before you move the

chain saw. Always stop the motor before moving

from tree to tree.

LIMBING A TREE

Limbing is removing the branches from a fallen

tree. When limbing leave larger lower limbs to

support the log off the ground. Remove the small

limbs in one cut (Fig. 16). Branches under tension

should be cut from the bottom up to avoid binding

the chain saw.

SAWING TECHNIQUES

Saw off the lower branches on the tree first. By do-

ing so, it is easier for the cut branches to fall to the

ground.

At the end of the cut, the weight of the saw sud-

denly increases for the user since it is no longer

being supported by a branch. There is a risk of los

ing control of the saw, so make sure to stay alert

during the entire sawing operation.

Only pull the saw out of a cut while the saw is run-

ning. By doing so, you prevent the chain from jam-

ming in the wood.

Bucking a Log

Stand on uphill side while cutting

because the log may roll.

Leave support limbs to keep work off the ground.

Do not saw with the tip of the guide bar. Do not saw into the branch formations (where the tree branch

es outwards). This will impede the tree’s ability to heal.

For sawing off smaller branches, place the stop face of the saw on the branch. This prevents unwanted

movements of the saw at the beginning of the cut. While applying light pressure, guide the saw through

the branch from top to bottom.

For sawing off larger branches, first make a relief cut. Saw through 1/3 of the branch diameter from

the bottom to top using the top side of the guide bar. Then saw from top to bottom for the other 2/3

using the bottom side of the guide bar. Saw off longer branches in sections in order to maintain control

over the location of impact.
