UMBmNG

Limbing a tree is the process of removing the branches from a fallen tree. Do not remove supporting iimbs (A) untii after the Hogis bucked (cut) into bngths (Fig, 16). Branches under tension shouid be cut from the bottom up to avoid binding the chain saw.

When bucking on a slope, always stand on the uphill side.

1.Log supported aiong entire bngth: Cut from top (over- buck), being carefui to avoid cutting into the ground (Fig. 17).

2.Log supported on 1 end: First, cut from bottom (underbuck) 1/3 diameter of Hogto avoid spiintering. Second, cut from above (overbuck) to meet first cut and avoid pinching (Fig. 18).

3.Log supported on both ends: First, overbuck 1/3 diame-

ter of Hogto avoid spiintering. Second, underbuck to meet first cut and avoid pinching (Fig. 19).

NOTE: The best way to hold a log while bucking is to use a sawhorse. When this is not possible, the log should be raised and supported by the limb

stumps or by using supporting logs. Be sure the log being cut is securely supported.

BUCKmNG

Bucking is cutting a falbn log into lengths, Make sure you have a good footing and stand uphill of the log when cut- ting on sbping ground. If possible, the bg shouM be sup- ported so that the end to be cut off is not resting on the ground. If the log is supported at both ends and you must cut in the middle, make a downward cut halfway through the log and then make the undercut. This will prevent the log from pinching the bar and chain. Be careful that the chain does not cut into the ground when bucking as this causes rapid dulling of the chain.

For personal safety and ease of cutting, the correct posi- tion for vertical bucking is essential (Fig. 20).

A.Hold the saw firmly with both hands and keep the saw to the right of your body while cutting.

B.Keep the left arm as straight as possible.

C.Keep weight on both feet.
