Finish cut

First cut

Board or flat stones

To fell big trees with a diameter exceeding twice the bar length, start the notching cuts from one side and draw the saw through to the other side of the notch.

Start the back cut on one side of the tree, pivoting the saw through to form the desired hinge on that side. Then remove the saw for the second cut. Insert the saw in the first cut, very carefully so as not to cause kick- back.

The final cut is made by drawing the saw forward in the cut to reach the hinge.

Limbing

Limbing a fallen tree is much the same as bucking. Never stand on the tree that you are limbing.

When limbing, caution is the word.

Be careful of the tip touching other limbs.

Always use both hands.

Don’t cut with the saw overhead or aligned vertically with your body. If the saw should kickback, you may not have enough control to prevent possible injury.

Bucking

Bucking is the sawing of a log or fallen tree into smaller pieces.

There are a few basic rules which apply to all bucking operations.

Keep both hands on the handles at all times. Support logs if possible.

When cutting on a slope or hillside, always stand uphill.

Keep in mind that the wood is heavy and that it will bend and pinch the saw if improperly supported. The trunk will weaken at the point where you make the cut unless the tree is lying on perfectly flat ground or supported as shown. If you make the cut with the tree on the ground, don’t let the saw’s chain dig into the earth; it is harmful for the saw, and you stand a good chance of being struck by flying debris.

To cut the trunk, use the bucking and two-cut sequence shown. The first cut should be no deeper than one-third the trunk diameter.

DANGER

Kickback is generated when the rotation of the chain is arrested for some reason.

The most dangerous effect of this action occurs when the nose of the bar contacts another object, the chain is momentarily stopped and all the energy of the engine throws the bar upwards and backwards towards the operator.

The chain saw industry and government agencies have attempted to prescribe various safety devices, but the best protection is to avoid kickback.

Comply with the safety precautions as listed in this Manual and Safety Manual.
