This consumer chain saw is intended for general homeowner
use, and such general applications as clearing, pruning, and
cutting firewood.
Before using your saw, you should review the safety precau-
tions listed in your Owner's Manual, and all local regulations
for the operation of your saw. These precautions and regula-
tions are for your protection.
For all types of cutting, always hold saw firmly with both
hands, with thumbs and fingers encircling saw handles.
Cut at high engine speeds (full throttle) only. Don't run the
engine slowly at the start or during the cut.
Pre-plan a safe exit from a falling tree or limbs.
Cut wood only,
Test the operation of the CHAIN BRAKE before cutting,
FElLING
Direction of fall is controlled by the undercut. Type" A" is
easy to make and is commonly used for small trees. Type
"8" leaves butt end of log cut squarely across. Type "C"
is a variation of Type" A". The notch should be about 1/3
diameter of the tree. On felling cut, do not cut through to
notch. Uncut band of wood parallel to notch serves as a
hinge. Make cuts in order shown - 1, 2, 3 on "A".@
When diameter of wood being cut is greater than bar length,
make two cuts as shown.@
BUCKING
When bucking on a slope, always stand on the up hill side,
LOG SUPPORTED ALONG ENTIRE LENGTH: Cut from top
(overbuck), being careful to avoid cutting earth.@
LOG SUPPORTED ON ONE END: First cut from bottom (under-
buck) 1/3 diameter of log to avoid splintering. Second, over-
buck to meet first cut and avoid pinching. ®
LOG SUPPORTED ON BOTH ENDS: First overbuck 1/3 dia-
meter of log to avoid splintering. Second, underbuck to meet
first cut and avoid pinching, ®
LIM BING
Keep the log off the ground. Do not remove supporting limbs
until after the log is bucked into lengths, ®
