SPECIAL NOTE
In some states, such as California, laws covering chain saws (having internal combustion engines}, when used in areas covered by
forests, brush or grass (excluding residential lawns and landscaped areas}, necessitate fitting the saw's muffler with an additional
heat shield to reduce muffler surface temperatures, Sears offers such a shield as an optional accessory kit° Muffler Heat Shield Kit
Catalog No. 32-36178 can be purchased at your Sears Service Center. Check with your state conservation or forestry department
about their regulations before operating this Sears Chain Saw on any forest-covered, brush-covered or grass-covered areas, Oregon
and Washington have similar requirements with respect to forest-covered lands°

TREE

FELLING

TECHNIQUE

A
SAFE
WORKING
PROCEDURE
IS
YOUR
FIRST
LINE
OF DEFENSE
TOWARD
PREVENTING
ACCIDENTS

1. SIZE UP THE TREE.
a. Determine
natural felling
direction
....
-- toward the direction
of natural lean.
-- toward the side with more or heavier branches.,
-- (if heavily leaved) with the direction
of the wind.t
b., Avoid felling
a tree ....
-- if it shows signs of rot which may make felling unpredictable.
-- if it's natural
felling
direction
must be changed to
avoid obstacles.,
-- if hanging dead limbs (_widov_
makers =_) cannot
be
removed before felling.,
-- if wind is strong or gusty.

2. PLAN YOUR ESCAPE ROUTE, Choose a route back and
to one side of the direction of tree fall (Fig, 17),, You
should plan a route that will place you at least twenty feet
from the stump at the time the tree hits the ground,
3. CLEAR THE BRUSH AND DEBRIS from around the tree
and along your escape route, Examine tree in cutting area
and remove dirt or foreign material which might dull or
break the chain as you cut_

,
a. Undercut
( notch

(Fig. 18),
-- Make the first cut horizontally
I/3 the tree diameter
at a comfortable
working
height.
-- Finish the undercut
with
sloping
cut to meet but
not cross the first,,
-- Clean out the undercut
wood.
fl
,
Ii
b. Backcut
( felling
cut )the tree opposite the notch (Fig..

18).
-

Make the horizontal
felling
cut opposite
the side of
natural
fall. at least 2 inches above the horizontal
undercut,,
-- For trees larger than bar length make two felling cuts
pivoting bar nose in last, in on one side. then pivoting
in from the other to complete
the cut (Fig. 19).
-- Some trees may need to be pushed into the undercut. Drive wedges into the backcut,
stopping
often
to drive wedges tight but taking care not to place
them where they will interfere with cutting
or direction of fallo Use plastic or wood wedges so that they
cannot dull saw chain if accidentally
hit.
-- DO NOT CUT COMPLETELY
THROUGH
TO THE
UNDERCUT.
Leave at least a 2 inch hinge to hold
and guide the tree down in the direction
you planned
and keep the tree from snapping off the stump., Make
sure to keep the hinge a uniform
thickness to prevent the tree from pivoting
on the stump°
5. ESCAPE.
As your backcut
nears the undercut,
watch the
treetop
and the cut for signs of movement.,
Be alert -- as
soon as the tree starts to move, pul! your saw from the
tree, turn it off, put it down, and move away quickly
on
you[ escape route. If your saw is pinched in the backcut-don t wait until
the falling
tree frees it., Shut if off and
leave itl

BE ALERT
TO CONDITIONS
WHICH
MIGHT
ALTER
YOUR PLANNED
ESCAPE ROUTE AND WATCH WHERE YOU
ARE GOINGI
6. STUDY THE STUMP. Improve your felling technique by
analyzing your work (Fig. 20).
a. Did the undercuts meet without crossing?
b;. Was the backcut horizontal, parallel to the undercut and
at least 2 inches above it?
c,, Was the hinge at least 2 inches thick and of uniform
thickness?

CHAIN

SHARPENING

If wood chips are becoming increasingly smaller as you cut,
from normal wear or accidental running Chain in dirt or sand,
your Chain may need sharpening. Check Chain for sharpness
or damage after every refueling and sharpen perhaps every
third or fourth refueling; more often when cutting seasoned
hard wood or frozen wood.

REPAIR

1. Chain Cutter and Link bottoms riding on Guide Bar Rails
will normally roll some Bar Material to the outside of the
_bails ff_pecially in actual cutting area of Guide Bar, These
urrs" should be removed as they form or they will chip
away during use taking more Bar material with them,
Check Bar for burrs at each Chain sharpening (Fig. 39),
a, Remove Guide Bar Nuts, Screw in rear of Chain Shield,
Chain Shield and Outer Chain Guide. Loosen Chain
Tension, remove Chain and Guide Bar,
bo Move your gloved hand across the flat of the Guide Bar
to feel burrs and remove them with a Flat Fife. Rounding outside Rail edges will retard further burr formation
(Fig, 40),
co Reassemble Saw and re-tension Chain (pages 3 and 4)°
NOTE: YOUR GUIDE

REPLACEMENT

Normal Chain sharpening will eventually remove enough mat _
erial to weaken Cutters and cause damage during use. Individual Cutters can be replaced and sharpened to match Chain
in a Sears Service Center, however, repeated Cutter or Link
breakage indicates Chain replacement is required°
NOTE: A damaged Cutter on Top Sharp Chain (MODEL
917.353770
& 917o353771), should not be replaced by
another Cutter due to the difficulty
in sharpening it to match
other worn Cutters, Use of a Tie Strap (Fig, 28) to replace an
individual damaged Cutter will not noticeably affect the cut °
ting ability of your chain,

Never store your Chain Saw for o_er 30 days without
ing the following procedures:

perform-

_,, Drain o{1 and fuel tanks in a safe area.,
2o Start Saw and run at idle speed until the engine stops,
This will remove most of the fuel from the fuel system.
3. Remove the Spark Plug and pour a teaspoonful of oil
through the spark plug hole into the combustion chamber
(Fig,, 52)° Pull the starter rope slowly several times to distribute the oil throughout the engine. Replace the Spark
Plug tightly and pull rope until resistance is felt, closing
intake and exhaust ports°
4., Remove and clean the Bar and Chain (use gloves when
handling chain).
5, Store the Chain in a container with oil covering chain,
6. Apply a heavy film of oil over the entire Bar including the
groove for the chaim Wrap bar in heavy paper, cloth or plas_
tic.
7, Clean the outside surfaces of the saw,
8,, Cover the saw with a protective cloth or plastic and store
