OPERATING CHAIN SAW
Continued
LIMBING A TREE
WARNING: Avoid kickback. Kick- back can result in severe injury or death. See Kickback, page 3, to avoid risk of kickback.
WARNING: When cutting limb that is under tension, use extreme caution. Be alert for wood springing back. When wood tension is released, limb could spring back and strike operator causing severe injury or death.
Limbing is removing branches from a fallen tree. Make sure your footing is Þrm. Keep feet apart. Di- vide your weight evenly on both feet. Do not remove larger limbs under tree that support log off ground. Remove each limb with one cut (see Figure 12). Clear cut limbs from work area often. This will help main- tain a safe work area.
Make sure you start your cut where limb will not pinch saw during cutting. To avoid pinching, start cut on freely hanging limbs from above limb. Start cut on limbs under tension from under limb. If pinch occurs, turn saw off, lift limb, and remove saw.
Bucking a log is cutting a log into sections. Make sure your footing is Þrm. Keep feet apart. Divide your weight evenly on both feet. When possible, raise log or section off ground. Do this by using limbs, logs, chocks, etc. When cutting through log, maintain control by re- ducing cutting pressure near end of cut. Do not relax your grip on chain saw handles. Do not let moving chain touch ground. Ground will dull moving chain. After cutting through log, release trigger to turn saw off before moving saw.
Follow directions below to buck a log.
Entire Length Of Log On Ground
Cut log from top (see Figure 13).
Log Supported On One End
1.Make Þrst cut on underside of log (see Figure 14). Use top of guide bar to make this cut. Cut 1/3 through diameter of log. This cut will keep sec- tion from splintering when cut.
2.Make second cut directly above Þrst cut. Cut down to meet Þrst cut. This cut will keep log from pinching guide bar and chain.
Log Supported On Both Ends
1.Make Þrst cut from above log (see Figure 15). Cut 1/3 through diameter of log. This cut will keep section from splintering when cut.
2.Make second cut on underside of log, directly under Þrst cut. Use top of guide bar to make this cut. Cut up to meet Þrst cut. This will keep log from pinching guide bar and chain.
BUCKING A LOG
WARNING: Avoid kickback. Kick- back can result in severe injury or death. See Kickback, page 3, to avoid risk of kickback.
WARNING:
¥If on slope, make sure log will not roll down hill. Secure log by using wooden stakes. Drive wooden stakes into ground on downhill side of log. Stand on uphill side of log while cutting. Log may roll after cutting.
¥Never try cutting through two logs at same time. This could
increase the risk of kickback.
¥While cutting log, never hold log with your hand, leg, or foot.
¥While cutting log, never allow another person to hold log.
¥Turn off and unplug saw before mov- ing from one place to another.
