STATE AND LOCAL ORDINANCE
REQUIREMENTS
Your saw is equipped with a temperature
limiting muffler and spark arresting-screen
which meets the requirements of_Califomia
_.;CodesA442 and 4443. All U.S: forest.land and :the-_
states of California, Ma_ne, Washington
and
Oregon require many internal combustion
engines to be equipped with a spark arrestor
screen and a temperature limiting muffler by
law.
tf you operate a chain saw in a state or locale
where such regulations exist, you are legally
responsible for maintaining the operating condition of these parts. Failure to do so could subject youto liability or to a fine. Muffler and spark
arrestor maintenance is found on page18.

ENGINE
FUEL
MIXTURE
• 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
engin_ requires lubrication of moving" parts.
Lubi:icatlon
is provided whenyouuse

1. USE THE
,e_The guide bar and cutting chain require continuous lubrication in order to remain in operi:ating condition. Lubrication is provided by
the automatic oiler system when the oil tank
iskept 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.

:
b. The saw will use about 112 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.
c. it is normal for a small amountofoil
to ap

CONTROLLING
KICKBACK
Kickback is a dangerous chain saw reaction that
can cause sedous 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 it kickback does
e. Operate the engine at full throttle for 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 specified for your particular
saw. These devices have been designed to
reduce the possibility of kickback.
g: Use extra caution if yoursaw is equipped
with the Power Sharp ® System. The Power
Sharp ® saw isequipped 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.
Occur.
•.1. 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

USING
THE POWER
SHARP ® SYSTEM
Model .354871 is equipped with a PowerSharp _.
System that will perform approximately 80% of
the sharpening necessary for the saw chain.
• The Power Sharp ® System uses a built-in grinding stone to sharpen the cutter top plates and
set depth gauges. As the built-in sharpener is_
.used, the cutter side plates gradually will be
altered. Hand filing is required to correct the
(MODEL
.354871)
• Always replace the sharpening stone when
--sparks
are no longer seen at full adjust.
ment
--only 1/4 inch of stone is remainlng
--stone
has become cracked or damaged.
_--a new chain is installed. The used stone
will be worn to the shape of the 01d chain
and can cause excessive wear to a new
chain. Replacement chain comes supplied
with Stone Cartridge Replacement#69099.
Refer to replacement instructions on page
12.

• Sharpen the saw chain when:
--wood chips become small and powdery;
_• i: . _Wood chips made by the chain should be
:
about the sizeof the teeth of the chain.
--saw cuts to one side.
•
_ --saw has to be forced through,the cut;
• Always remove the sharpening stone/f a con.
ventional chain is substituted for the PoWer
Sharp ® Chain. See instructions for removing
the Stone Cartridge on page 12. Use replacement chain #32-3638. Follow chain sharpening instructions on page 16.
[CAUTION:] ALways wear gloves when handling
the chain. The chain can be sharp enough tocut
.... you, even when it is too dull to cut wood.

your saw before you begin a major sawing
operation.

a.Accelerate
the engine to full thfottle just

entire
time you are cuffing,
d, Allow the chain-to cut for you; exert only
light downward pressure. If you .force the
cut, damage to the bar, chain, or engine

e. Release the Throttle as soon as the cut is
completed, allowing the engine to idle. If
you run the saw at full throttle without a

The notch method is used to cut large trees. A

is cut on the side of the tree in the
desired direction of fail. After a felling cut is
made on the opposite side of the tree, the tree
will tend to fall into the notch.
a. Make the notch cut. Figure 28.

the notch by making the

3_) Remove the notchof wood.
NOTE: The hinge helps to keep the tree
fromtwisting
and falling in the wrong direction.
d. Use a wedge if there is any chance that the
tree will not fall in the desired direction.
NOTE: Stop cutting before the felling cut is
complete; use a wedge to open up the cut,
e. Be alert for signs that the tree is ready to
fall:
1.) cracking sounds
2.) widening of the felling cut
3.) movement in the upper branches.
b. Make the felling cut onthe opposite side of
the notch about 2" higher than the bottom
of the notch.

done safely and properly.
b. Leave the larger lower limbs to support the
tree as you work.
c. Start at the base of the felled tree and work
towards the top cutting =)ranches and
limbs. Remove small limbs with one cut.
Figure 34.
d. Keep the tree between you and the chain.
Cut from the side of the tree opposite the
branch you are cutting.
e. Remove larger, supporting branches with
the 113, 2/3 cutting technique described in
the bucking section.
1.) Start with an overcut
2.) Finish with an undercut
2. PRUNING
a. Limit pruning to limbs shoulder height or
below. Do not cut if branches are higher
than your shoulder. Get a professional to
do the job.
b. Refer to Figure 35 for the pruning technique.
1.) Undercut 1/3 of the way through the
limb near the trunk of the tree.
2.) Finish with an overcut farther out from
the trunk.
3.) Keep out of the way of the falling limb.

fan housing. Figure 46.
....
NOTE: Notice the different lengths of the
screws and their proper locations while
removing the screws.
2. Remove the fan housing.
;3. If the starter rope is not broken, release the
spring tension by pulling about 12 inches of
;:
rope from the pulley and catch the rope in
the notch as shown. Figure 47.

mid-point between the two positions.
4. IDLE SPEED ADJUSTMENTBII
a. Allow engine toidle.
............ b._Adjust if the chain is turning by turning the
Idle SpeedScrew counterclockwise
_
.
c. Squeeze the throttle trigger;, The saw
should accelerate without hesitating.
NOTE:It may be necessary to recheck the
low speed mixture setting after the idle
speed has been.reduced by repeating "Low
Speed Mixture Adjustment" as in step 3
above.
5, HIGH SPEED MIXTURE ADJUSTMENT
a. Make a test cut.
b. Adjust if the saw smokes or seems to have
low power in the test cut by turning the
High Speed Mixture Screw 1116th of a turn
