BUCKING

See Figure 26.

Bucking is the term used for cutting a fallen tree to the desired log length.

nCut only one log at a time.

nSupport small logs on a saw horse or another log while bucking.

nKeep a clear cutting area. Make sure that no objects can contact the guide bar nose and chain during cutting, this can cause kickback. To avoid the danger, keep the SAFE-T-TIP®anti-kickback device attached while cutting. Refer to Kickback in the Specific Safety Rules section of this manual for more information.

■n During bucking operations, stand on the uphill side so that the cut-off section of the log cannot roll over you.

■n Sometimes it is impossible to avoid pinching (with just standard cutting techniques) or dif- ficult to predict which way a log will settle when cut.

WEDGE

BUCKING WITH A WEDGE

Fig. 27

See Figure 27.

 

If the wood diameter is large enough for you to insert a soft bucking wedge without touching the chain, you should use the wedge to hold the cut open to prevent pinching.

NOTE:  When bucking or felling with a wedge, you may need to remove the SAFE-T-TIP®anti-kickback device to allow the bar to be drawn through the cut. After you complete the cut, reinstall the tip.
