BUCKING A LOG
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
reducing 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.

CHAIN SAw INFORMATION
wARNING: Avoid kickback.
Kickback can result in severe injury
or death. See
Kickback,
page 5, to
avoid risk of kickback.
Log Supported On Both Ends
1. Make first cut from above log (see
Figure 19). 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 first cut. Use top of guide
bar to make this cut. Cut up to meet first
cut. This will keep log from pinching
guide bar and chain.

weight evenly on both feet. Follow directions
below to trim a tree.

on underside of limb. Use top of guide
bar to make this cut. Cut 1/3 through
diameter of limb (see Figure 20).
2. Move two to four inches farther out
on limb. Make second cut from above
limb. Continue cut until you cut limb

3. Make third cut as close to tree trunk as
possible on underside of limb stub. Use
top of guide bar to make this cut. Cut
