OPERATING CHAIN SAW
BUCKING A LOG
WARNING: Avoid kickback. Kickback
can result in severe injury or death. See
Kickback 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 moving
from one place to another.
Bucking a log is cutting a log into sections. Make
sure your footing is firm. 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 reduc-
ing 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.

Log Supported On One End
1. Make first cut on underside of log (see Figure
11). Use top of guide bar to make this cut. Cut
1/3 through diameter of log. This cut will keep
section from splintering when cut.
2. Make second cut directly above first cut. Cut
down to meet first cut. This cut will keep log
from pinching guide bar and chain.
Log Supported On Both Ends

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
