R_QUmREM_NTS
Your saw is equipped with a temperature
limiting muffler and spark arresting screen
which meets the requirements of California
Codes 4442 and 4443. All U.S. forest land and the
states of California, Maine, Washington and
Oregon require many internal combustion
engines to be equipped with a spark arrestor
screen and a temperature limiting muffler by
law.
If you operate a chain saw in a state or locale
where such regulations exist, you are legally
responsible for maintaining the operating condi-
tion of these parts. Failure to do so could sub.
ject you to liability or to a finer Muffler and spark
arrestor maintenance is found on page 18.

CHAMN TENSUON
e Correct chain tension is very important:
--a loose chain will wear the bar and itself,
--a loose chain can jump off the bar while
you are cutting_
--a tight chain can damage the saw andtor
break,
--a chain, either too loose or too tight, can
cause injury,
Chain tension is correct when the chain:
--can be lifted about 1/8" from the Guide Bar
at a point near the middle of the bar, and
--will move freely around the bar.
The chain stretches during use, especially
when new. Check tension:
--each time the saw is used
--more frequently when the chain is new
O
The Bar Clamp Nuts must be slightly loose to
tension the chain correctly.
.
Hold the tip of the Guide Bar up and turn the
Adjusting Screw just until the chain does not
sag beneath the Guide Bar, Figure 9.
2 Check the tension by lifting the chain from
the Guide Bar at the center of the bar, Figure
10,
3, Continue turning the Adjusting Screw until
the tension is correct.

F, ENGgNE FU_L MSXTURE
e Your chain saw is powered by a two-cycle
engine which requires a fuel mixture of
regular gasoline and a high quality engine oil
specially made for 2.cycle, air.cooled
engines. The internal design of the 2-cycle
engine requires lubrication of moving part&
Lubrication is provided when you use the
recommended mixture of gasoline and oil,
Gasoline must be clean and not over two
months old. After a short period of time,
gasoline begins to chemically break down
and will form compounds that can cause hard
starting and damage in 2-cycle engines°
The correct measure of gasoline to oil is very
important.
--Too much oil in the mixture wilt foul the
spark plug.
--Too littte oil will cause the engine to over-
heat resulting in damage.
@
Mix the fuel thoroughly in a container since
gasoline and oil do not readily combine. Do
not try to mix fuel directly in the fuel tank,,

G. RAR AND CHAIIN OliL
e The guide bar and cutting chain require con-
tinuous lubrication in order to remain in
operation condition. Lubrication is provided
by the automatic oiler system when the oil
tank is kept filled.,
--Lack of oil will quickly ruin the bar and
chain.
--Too little oil will cause overheating shown
by smoke coming from the chain and/or
discoloration of the guide bar rails
O
Use SEARS Bar and Chain Lubricant #36554
or clean SAE 30W oil.
e
In freezing weather oil will thicken, making it
necessary to thin bar and chain oil with a
small amount of Diesel Fuel #1 or Kerosene.
Bar and chain oil must be free flowing for the
oil system to pump enough oiI for adequate
a Use only recommended fuel mixtures.
b, Eliminate all sources of sparks or flame in
the areas where fuel is mixed, poured, or
stored. There should be no smoking, open
flames or work that could cause sparks
c Mix and store fuel in an approved, marked
container.
d. Mix and pour fuel in a well-ventilated area.
Gasoline vapors are harmful to your health
and are a serious fire hazard
e. Avoid over filling the fuel tank. Allow 3/4
inch for expansion. Tighten Fuel Cap
securely Figure 11
f. Wipe up all fuel spills. Wipe off any fuel
spilled on the saw, Completely dry the saw
before using,,
g. Move at least 10 feet (3 meters) away from
fuel and fueling site before starting the
engine,
1. USE THE FOLLOWING:
30°F or above -- Lubricant -- undiluted,
30OF . 0OF _
95% lubricant to 5% Diesel
Fuel #1 or Kerosene,
Below O°F --
90% lubricant to 10%
Diesel Fuel #I or Kerosene
2, HOW TO FILL THE OIL TANK
a. Stop the engine.
bl Turn saw on its side with oil cap up Figure
t2
CoLoosen cap slowly and wait for pressure in
the tank to be released before removing the
cap.
d. Fill the oil tank°
Replace the oil cap securely,
Figure 12
3, IMPORTANT POINTS TO REMEMBER
Fill the oil tank each time you refill the fuel
tank to ensure there wil! be sufficient oil for
the chain whenever you start and run the
saw,,
The saw will use about t/2 tank of chain oil
for each tank of fuel mixture. If less oil is
used, check for a plugged oil hole in the
guide bar,
It is normal for a small amount of oil to ap-
pear under the saw after the engine stops.
This is due to oil draining from the bar and
chain when not in use

C= CONTROU- NG KmCKBACK
Kickback is a dangerous chain saw reaction that
can cause serious personal injury. Carefully
study this section before you make the first cut
with your new saw. You must understand what
causes kickback, how you can reduce the
chance of kickback, and how you can remain in
the best control of the saw if kickback does
OCCUr
WHAT CAUSES KICKBACK
Kickback can happen when the moving chain
contacts an object at the tip of the guide bar
while the saw is being operated This contact
causes the chain to dig into the object and
stops the chain for an instant. The result is a
lightning fast, reverse reaction which kicks
the saw tip up and back at the operator The
operator can lose control of the saw and the
cutting chain can cause serious injury if it
contacts any part of the body,
HOW YOU CAN REDUCE THE CHANCE
OF KICKBACK
a. Recognize that Kickback can happen. By
understanding and knowing about kick-
back, you eliminate the element of sur-
prise.
b. Avoid Setting the moving chain at the tip of
the guide bar contact any object. Figure 15
c_ Keep the working area free from obstruc-
tions such as other trees, branches, rocks,
fences, stumps, etc. Figure 16 Eliminate or
avoid any obstruction that your saw chain
could hit white you are cutting through a
particular log or branch
do Keep your saw chain sharp and properly
tensioned. A loose or dull chain can in-
crease the chance of kickback
KICKBACK PATH
e Operate the engine at full throttle foi" all
cutting. If the chain is moving at a slower
speed, there is greater chance for kickback
to occur.
f Use the Lo Kick Guide Bar and Guard Link
Chain designed for your particular saw.
These devices have been designed to
reduce the possibility of kickback.
g. Use extra caution if your saw is equipped
with the Power Sharp System. The Power
Sharp saw is equipped with a Lo Kick
Guide Bar and a Guard Link Chain_
However, due to the chain requirements of
the built-in sharpening mechanism, the
kickback force from the Power Sharp chain
may be greater than that from other Guard
Link chains.
&HOW YOU CAN MAINTAIN THE BEST
CONTROL
a, Keep a good firm grip on the saw with both
hands. Figure17 A firm grip can neutralize
kickback and help you maintain control of
the saw, Keep the fingers of your left hand
encircling and your left thumb under the
front handlebar, Keep your right hand com-
pletely around the rear handle Keep your
left arm straight with the elbow locked
b Position your left hand on the front
handlebar so it is in a straight line with your
right hand on the rear handle. Figure 18
Never reverse right and left hand positions
on the saw handles..
c° Stand with your weight evenly balanced on
both feet.
dr Stand slightly to the left side of the saw, to
keep your body from being in a direct line
with the cutting chain. Figure 17

thrown off balance and lose control of the
saw..

difficult to maintain control of the saw if
you try to cut above shoulder height,
