Safety precautions for chain saw operators
While operating the chain saw please observe the
following rules:
a) Contact of the guide bar nose with any object
should be avoided.
b) Tip contact may cause the guide bar to move
suddenly upward and backward, which may cause
serious or fatal injury.
WARNING!
Read and follow all safety precautions in the
operator’s manual. Failure to follow instructions could
result in serious injury. It is recommended to lend
the chain saw only to people who are experienced
in working with chain saws. Always hand over the
Operator’s and Safety Manual.
WARNING!
This chain saw is capable of severe kickback that
could result in serious injury to the operator. Do not
operate this chain saw unless you have extraordinary
cutting needs and experience in and special training
for dealing with kickback.
Chainsawswithsignicantlyreducedkickback
potential are available.
Kickback safety precautions
WARNING!
Kickback may occur when the nose or tip of the guide
bar touches an object, or when the wood closes in
and pinches the saw chain in the cut. Tip contact
in some cases may cause a lightning-fast reverse
reaction, kicking the guide bar up and back toward
the operator. Pinching the saw chain along the top
of the guide bar may push the guide bar rapidly
back toward the operator. Either of these reactions
may cause you to lose control of the saw, which
could result in serious personal injury. Do not rely
exclusively upon the safety devices built into your
saw. As a chain saw user, you should take several
steps to keep your cutting jobs free from accident or
injury.
a) With a basic understanding of kickback, you
can reduce or eliminate the element of surprise.
Sudden surprise contributes to accidents.
b)
Keepagoodrmgriponthesawwithbothhands,
the right hand on the rear handle and the left hand on
the front handle, when the engine is running. Use a
rmgripwiththumbsandngersencirclingthechain
sawhandles.Armgripwillhelpreducekickbackand
maintain control of the saw. Don’t let go.
c) Make sure that the area in which you are cutting
is free from obstructions. Do not let the nose of
the guide bar contact a log, branch, or any other
obstruction that could be hit while you are operating
the saw.
d) Cut at high engine speeds.
e) Do not overreach or cut above shoulder height.
f) Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain.
g)Onlyusereplacementbarsandchainsspeciedby
the manufacturer or the equivalent.
Additional safety precautions
The following additional safety precautions must be
observed by all users of chain saws:
- A chain saw is intended for two-handed use. Do not
operate a chain saw with one hand! Serious injury
to the operator, helpers, bystanders may result from
one-handed operation.
- Whenachainsawisbeingused,areextinguisher
should be available.
- Follow the instructions in your operator’s manual for
starting the chain saw and control the chain saw with
armgriponbothhandleswhenitisinoperation.
Keep handles dry, clean, and free of oil or fuel
mixture.
- Do not operate a chain saw when you are fatigued.
Fatigue causes carelessness. Be more cautious
before rest periods and towards the end of your shift.
- Personal protective clothing required by your safety
organizations, government regulations, or your
employer should be used. At all times when using a
chainsaw,snug-ttingclothing,protectiveeyewear,
safety footwear, and hand, leg, head and hearing
protection should be worn.
Note: Personal protective clothing should meet the
requirements of applicable CSA and BNQ
Standards.
- Use caution when handling fuel. Before fuelling,
servicing, or transporting your chain saw, switch off
theengine.Tohelppreventre,restartyourchain
saw at least 3 m (10 ft) from the fuelling area.
- Keep other persons or animals a safe distance away
from a running chain saw or the area where a tree is
being felled.
- Always keep proper footing and operate the chain saw
onlywhenstandingonaxed,secure,andlevelsurface,
and a planned retreat path from the falling tree.
- Keep all parts of your body away from the saw chain
when the engine is running.
- Before you start the engine, make sure that the saw
chain is not contacting anything.
- Carry the chain saw by the front handle with the
engine stopped, the guide bar and saw chain to the
rear,andthemuferawayfromyourbody.
- When transporting, storing or not in use, always use
theappropriateguidebarcover.Itmusttandfully
cover the guide bar on the chain saw.
- Never operate a chain saw that is damaged or
improperly adjusted or that is not completely and
securely assembled. Be sure that the saw chain
stops moving when the power control system trigger
is released. Never adjust the guide bar or saw chain
when the engine is operating.
- Shut off the engine before setting the chain saw down.
- Use extreme caution when cutting small-size brush
and saplings because slender material may catch the
saw chain and be whipped toward you or pull you off
balance.
- When cutting a limb that is under tension, be alert for
spring back so that you will not be struck when the
tensioninthewoodbersisreleased.
- When felling, keep at least two tree lengths away
from other persons or animals.
- Beware of carbon monoxide poisoning. Operate the
chain saw in well-ventilated areas only.
- Allow your chain saw to cool before refuelling, and do
not smoke.
- Do not attempt a pruning or limbing operation in a
standingtreeunlessspecicallytrainedtodoso.
- All chain saw service, other than the items listed in
the operator’s manuals maintenance instructions,
should be performed by competent chain saw service
personnel. (For example, if improper tools are used
toremovetheywheelorifanimpropertoolisused
toholdtheywheelinordertoremovetheclutch,
structuraldamagetotheywheelcouldoccurand
subsequentlycouldcausetheywheeltoburst.)
- Thisgas-poweredsawisclassiedbyCSAasa
Class 1A saw. It is a professional chain saw, intended
for use by trained workers, where the operator is
expected to use the chain saw for extended periods
of time on a daily basis.
- Hold the chain saw by the insulated gripping surface
only, because the saw chain may contact hidden
electrical wiring.

General Safety Precautions
The use of any chain saw may be hazardous. At full
throttle chain speed can reach 45 mph (20 m/s). It is
important that you read; fully understand and observe
the following safety precautions and warnings. Read the
Operator’s Manual and the safety instructions periodically.
WARNING !
Reactive forces, including kickback, can be
da n gerous. Careless or improper use of any chain
saw may cause serious or fatal injury.
Have your MAKITA dealer show you how to
operate your chain saw. Observe all applicable
local safety regulations, standards and ordinances.
Maximum Computed Kickback Angle
(CKA)* with using the chain brake when
using the recommended bar and chain
combinations (In this example the CKA is 40°).
WARNING !
Prolonged use of chain saws exposing the operator
tovibrationsmayproduceWhitengerdisease
(Ray naud’s phenomenon). This phenomenon
reduces the hand’s ability to feel and regulate
temperature, produces numbness and burning
sensations and may cause nerve and circulation
damage and tissue necrosis.
All MAKITA saws are therefore provided with an
antivibration system which is essential for those
using chain saws on a regular or sustained basis.
Antivibration systems do not guarantee that you
willnotsustainWhitengerdisesase,however,they
reduce this danger considerably. Nevertheless,
continual and regular users should observe their
handsandngersandincaseofanyabnormal
symptoms, seek medical advice immediately.

Physical Condition
You must be in good physical condition and mental
healthandnotundertheinuenceofanysubstance
(drugs, alcohol), which might impair vision, dexterity
or judgment.
Always use two hands when
operating the chain saw!

WARNING !
Never modify a chain saw in any way. Only
attachments supplied by MAKITA or expressly
approvedbyMAKITAforusewiththespecicsaw
are authorized.
WARNING !
Bow guide bars substantially increase the potential
for kickback and severe or fatal injury due to the
greater kickback zone of the bow design. Bow
guide bars are not recommended for use on
MAKITA chain saws nor are they approved by the
ANSI B175.1-2012 chain saw safety standard.
The use of the saw
Transporting the chain saw
WARNING!
Always stop the engine before putting a chain saw
down or carrying it. Carrying a chain saw with the
engine running is extremely dangerous. Accidental
acceleration of the engine can cause the chain to
rotate.
Avoidtouchingthehotmufer.
By hand: When carrying your saw by hand, the
engine must be stopped and the saw must be in
the proper position.
The chain protection cover should be over the
chain and the guide bar must point backwards.
When carrying your saw the bar should be behind
you(g.4).
By vehicle: When transporting in a vehicle, keep
chain and bar covered with the chain guard.
Properly secure your saw to prevent turnover, fuel
spillage and damage to the saw. Make sure the
saw in not exposed to heat or sparks.
Proper clothing
Clothingmustbesturdyandsnug-tting,butallow
completefreedomofmovement.Avoidloose-tting
jackets,scarfs,neckties,jewelry,aredorcuffedpants,
or anything that could become entangled with the
saw or brush. Wear overalls or jeans with a reinforced
cuttingresistantinsert(g.3).
Protect your hands with gloves when handling saw and
saw chain. Heavy-duty, nonslip gloves improve your
grip and protect your hands.
Good footing is most important in chain saw work.
Wear sturdy boots with nonslip soles. Steel-toed safety
boots are recommended.
Proper eye protection is a must. Non-fogging, vented
goggles and a face screen is recommended. Their
use reduces the risk of eye and facial injury.
Wear an approved safety hard hat to protect your
head. Chain saw noise may damage your hearing.
Always wear noise protection equipment (ear plugs
or ear muffs) to protect your hearing.
Continual and regular users should have their hearing
checked regularly.
Sawing dry wood can create dust. Use a suitable dust
mask.

Wipe off any spilled fuel before starting your saw and
check for leakage.
Check for fuel leakage while refueling and during
operation. If fuel or oil leakage is found, do not start or
runtheengineuntilleakisxedandspilledfuelhas
been wiped away. Clothing with fuel on it has to be
changed immediately (this is a danger to your life!).
Avoid skin contact with fuel. Never loosen or remove
the cap of the fuel tank while the engine is running.
Starting
Do not drop start. This method is very dangerous
becauseyoumaylosecontrolofthesaw(g.6).
WARNING!
Gasolineisanextremelyammablefuel.Use
extreme caution when handling gasoline or fuel mix.
Donotsmokeorbringanysparksoramenearthe
fuel(g.5).
Fueling instructions
Fuel your chain saw in well ventilated areas or out-
doors. Always shut off the engine and allow it to cool
before refueling. Select bare ground for fueling and
move the chain saw at least 10 feet (3 m) from fueling
spotbeforestartingtheengine(g.5a).
Placethechainsawonrmgroundorothersolid
surface in an open area. Maintain a good balance and
secure footing. Place your right foot through the rear
handleopeningandrmlygraspthefronthandlewith
yourlefthand(g.6a).
Be absolutely sure that guide bar and chain are clear
of you or all other obstructions and objects, including
the ground, because when the engine starts in semi-
throttle position, engine speed will be fast enough for
the clutch to engage the sprocket and turn the chain
which may cause a kickback.
Never attempt to start the saw when the guide bar is in
a cut or kerf.
When you pull the starter grip, don’t wrap the starter
rope around your hands. Do not allow the grip to snap
back, but guide the starter rope slowly back to permit
the rope to rewind properly.
Failure to follow this procedure may result in injury
tohandorngersandmaydamagethestarter
mechanism.
Chain saw operating instructions
For assembly follow the procedure in the appropriate
section "Mounting Guide Bar and Chain" of this manual.
MAKITA chain, guide bar and sprocket must match
each other (see the appropriate section in this manual).
WARNING!
Proper tension of the chain is extremely important. In
order to avoid false setting the tensioning procedure
must be followed as described in this manual. Always
make sure the hexagonal nut(s) for the sprocket
guard is (are) tightened securely after tensioning the
chain.
Check chain tension once more after having
tightened the nuts and thereafter at regular intervals
(always before starting to work). If the chain
becomes loose while cutting, shut off the engine and
then tighten. Never try to tighten the chain while the
engine is running!
Fueling
Your MAKITA saw uses on oil-gasoline mixture for fuel
(see chapter "Fuel" of this manual).

Important adjustments
WARNING!
At correct idle speed, chain should not turn. For
directions to adjust idle speed, see the appropriate
section of this operator’s manual.
Do not use a saw with incorrect idle speed adjust-
ment. Adjust the idle speed yourself according to
the appropriate section of this manual.
Have your MAKITA dealer check your saw and
make proper adjustments or repairs.
Check the saw chain tension frequently, especially
just after installing a new chain. New chains may
stretch more during their initial use. A properly
adjusted saw chain can be pulled freely around the
guide bar by hand without sagging. Always stop the
engine and wear gloves when checking or ad justing
the chain tension.
Working conditions
Operate your chain saw only outdoors. Operate the saw
under good visibility and daylight conditions only.
WARNING!
Take extreme care in wet and freezing weather
(rain, snow, ice). Put off the work when the weather
is windy, stormy or rainfall is heavy. Clear the area
where you are working.
WARNING!
Avoid stumbling on obstacles such as stumps,
roots or rocks and watch out for holes or ditches.
Be extremely cautious when working on slopes
or uneven ground. There is increased danger of
slipping on freshly debarked logs.
Cutting instructions
Alwaysholdthesawrmlywithbothhandswhenthe
engine is running. Place your left hand on the tubular
handle and your right hand on grip and throttle lever.
Left-handers should follow these instructions too.
WARNING!
Do not operate your chain saw in semi-throttle
position. Cutting in this position does not permit the
operator proper control of the saw or chain speed.
WARNING!
Never come too close to a rotating chain with your
hands or body.
WARNING!
Cut wood only. Do not use the chain saw for
purposes not intended. For example: do not use
the chain saw for cutting plastic, masonry, or
non-wood building materials.
Use your chain saw for cutting only. It is not
designed for prying or shoveling away limbs, roots
or other objects.
When sawing, make sure that the saw chain does
not touch any foreign materials such as rocks, nails
andthelike(g.8).Suchobjectsmaybeungoff,
damage the saw chain or cause the saw to
kickback.
If the chain saw is exposed to force, such as
through impact or falling, inspect the entire chain
saw for proper functioning.
Wrapyourngerstightlyaroundthehandles,keeping
thehandlescradledbetweenyourthumbandforenger
(g.7).Withyourhandsinthisposition,youcanbest
oppose and absorb the push, pull and kickback forces
of your saw without having it slip out of your grip (see
section of reactive forces).
Make sure your chain saw handle and grip are in good
condition and free of moisture, pitch, oil or grease.
Always start a cut with the chain running at full speed
and the spike bar in contact with the wood.
When starting a cut, the blade can slip to the side
or jump slightly. This depends on the wood and the
condition of the chain. Therefore, always hold the
chain saw with both hands.
WARNING!
Never use the saw with one hand. You cannot
control reactive forces (see pages 9 to 11) and
may lose control of the saw.

Position the chain saw in such a way that your body is
clear of the cutting attachment whenever the engine is
running(g.10).
Don’t put pressure on the saw when reaching the end
of a cut. The pressure may cause the bar and rotating
chain to pop out of the cut or kerf, go out of control and
strike the operator or some other object. If the rotating
chain strikes some other object a reactive force (see
pages 10 to 12) may cause the chain to strike the
operator.
Reactive forces during the cut, including kickback
WARNING!
Reactive forces, that may occur during any cut are
kickback, pushback and pull-in. Reactive forces
can be dangerous! In any chain saw, the powerful
force used to cut wood can be reversed (and work
against the operator).
If the rotating chain is suddenly stopped by contact
with any solid object like a log or branch or is
pinched, the reactive forces instantly occur.
These reactive forces may result in loss of control
which may, in turn, cause serious or fatal injury.
An understanding of the causes of these reactive
forces may help you avoid loss of control.
The most common reactive forces are
- kickback,
- pushback,
- pull-in.
In order to keep control of your saw, always maintain
armfoothold.Neverworkonaladder,inatreeoron
any other insecure support. Never use the saw above
shoulderheight(g.9).
This reaction can occur in a fraction of a second and
under some circumstances, cause the guide bar and
chain to strike the operator with enough force to cause
severe or fatal injury. It may also occur during limbing.
It also occurs when the nose of the guide bar is
pinched unexpectedly, unintentionally contacts solid
materialinthewood(g.12)orisincorrectlyusedto
begin a plunge or boring cut.
The greater the force of the kickback reaction, the more
difcultitbecomesfortheoperatortocontrolthesaw.
Kickback:
Kickback occurs when the upper quadrant of the
bar nose contacts a solid object in the wood or is
pinched(g.11).Thereactionofthecuttingforceof
the chain causes a rotational force of the chain saw in
the direc tion opposite to the chain movement, mainly
intheplaneofthebar.Thismayingthebarinan
uncontrolled arc towards the operator.

To avoid kickback
The best protection from personal-injury that may
result from kickback is to avoid kickback situations:
1. Holdthechainsawrmlywithbothhandsand
maintain a secure grip.
2. Be aware of the location of the guide bar nose at
all times.
3. Never bring the nose of the guide bar in contact
with any object.
Do not cut limbs with the nose of the guide bar. Be
especially careful with small, tough limbs, small
size brush and saplings which may easily catch
the chain.
4. Don’t overreach.
5. Don’t cut above shoulder height.
6. Begin cutting and continue at full throttle.
7. Cut only one log at a time.
8. Use extreme caution when re-entering a previous
cut.
9. Do not attempt plunge cuts (see page 13) if you
are not experienced with these cutting techniques.
10. Be alert for shifting of the log or other forces that
may cause the cut to close and pinch the chain.
11. Maintain saw chain properly. Cut with a correctly
sharpened, properly tensioned chain at all times.
12. Stand to the side of the cutting path of the chain
saw.
Manyfactorsinuencetheoccurenceandforceofthe
kickback reaction. The type of bar and saw chain you
use is a factor in the force of the kickback reaction.
The speed of contact at which the cutter contacts
the object.
Kickback force increase with the rate of impact.
The contact angle between the nose of the bar and
the foreign object (g.11).
Kickback is most pronounced in the upper quadrant of
the bar nose.
MAKITA chain types are designed to reduce kickback
forces.
The depth gauges:
Improper lowering of the depth gauges also increases
the risk of a kickback.
Saw chain cutter sharpness:
WARNING!
A dull improperly sharpened chain may increase
the risk of kickback. Always cut with a properly
sharpened chain.
Devices for reducing the risk of kickback injury
MAKITA have developed a special chain brake to
reduce the risk of kickbacks.
This chain brake increases the safety factor on the job,
e.g. when the saw suddenly bucks upwards the chain
stops rotating within a fraction of a second.
Adeectionguardonthedisengagingleverofthe
chain brake and a scoop rear handle ensure that the
operator’s hands are fully protected at all times.
Kickback tendency increases as the radius or size of
the guide bar nose increases. MAKITA have developed
guide bars with small nose radius, to reduce the
kickback tendency.
WARNING!
No chain brake prevents kickback.
These brakes are designed only to stop the chain,
if activated.
To ensure a proper operation of the chain brake, it
must be properly maintained.
Furthermore,theremustbeasufcientdistance
between the operator and the bar to ensure that
thechainbrakehassufcienttimetoactivateand
stop the chain before potential contact with the
operator.
11

15
To avoid pushback
1. Be alert to forces or situations that may cause
material to pinch the top of the chain.
2. Do not cut more than one log at a time.
3. Do not twist the saw when withdrawing the bar from
aplungecutorunderbuckcut(gures25to27
and 33, pages 13 and 15), because the chain can
pinch.
Pull-in:
Pull-in occurs when the chain on the bottom of the bar
is suddenly stopped. The chain on the bottom of the
bar stops when it is pinched, caught or encounters a
foreignobjectinthewood(seeg.15).Thereactionof
the chain pulls the saw forward, causing the operator to
lose control.
Pull-in frequently occurs when the spike bar of the
saw is not held securely against the tree or limb and
when the chain is not rotating at full speed before it
contacts the wood.
WARNING!
Use extreme caution when cutting small size brush
and saplings which may easily catch the chain and
pull you off balance.
To avoid pull-in
1. Always start a cut with the chain rotating at full
speed and the spike bar in contact with the wood.
2. Pull-in may also be prevented by using plastic
wedges to open the kerf or cut.
Cutting techniques
Felling
Felling is cutting down a tree.
Before felling a tree, consider carefully all conditions
which may affect the direction of fall, including:
The intended direction of the fall.
The neutral lean of the tree.
Any unusually heavy limb structure.
Surrounding trees and obstacles.
The wind direction and speed.
WARNING!
Always observe the general condition of the tree.
Look for decay and rot in the trunk. If it is rotted
inside, it could snap and fall toward the operator
while being cut.
Also look for broken or dead branches which could
vibrate loose and fall on the operator. When felling
on a slope, the operator should stand on the up-hill
side.
Pushback:
Pushback occurs when the chain on the top of the
bar is suddenly stopped when it is pinched, caught or
encounters a foreign object in the wood.
The reaction of the chain drives the saw straight
back toward the operator causing loss of saw control.
Pushback fre-quently occurs when the top of the bar is
usedforcutting(g.14).
When felling in the vicinity of roads, railways and
power lines, etc., take extra precautions (see
g.16).Informthepolice,utilitycompanyor
railway authority before beginning to cut.

First clear the tree base and work area from inter fering
limbs and brush and clean its lower portion an axe (see
g.18).
When felling, maintain a distance of at least 2 1/2 tree
lengthsfromthenearestperson(seeg.17).
Note:
The noise of your engine may drown any warning call.
Felling instructions:
Plan your work, ensuring an obstacle-free work area
and, in the case of felling, have at least one escape
path from the falling tree prepared in advance.
Then, establish a path of escape and remove all
obstacles. This path should be opposite to the planned
direction of the fall of the tree and at a 45° angle
(g.19).
An alternate path must also be selected. Place all tools
and equipment a safe distance away from the tree, but
not on the escape path.
Then, determine the placement of the felling notch
(g.21).Thefellingnotchwhenproperlyplaced
determines the direction in which the tree will fall. It is
made perpendicular to the line of fall and should be as
close to the ground as possible.
Cutthefellingnotchtoadepthofaboutone-fthtoone-
fourthofthetrunkdiameter(g.22).Itshouldbeinno
case higher than it is deep. Make the felling notch very
carefully.
If the tree has large buttress roots, cut into the largest
buttressesverticallyrst(horizontallynext)andremove
(g.20).

Begin the felling cut slighty higher than the felling notch
andontheoppositesideofthetree(g.22).Thencut
horizontally through towards the felling notch. Apply
the chain saw with its spikes directly behind the uncut
portionofwoodandcuttowardthenotch(g.23).
Leave approximately 1/10 of the tree diameter uncut!
Thisisthehinge(g.23).Donotcutthroughthehinge
because you could lose control of the direction of the
fall. Drive wedges into the felling cut where necessary
to control the direction of the fall. Wedges should be of
wood, light alloy or plastic - never of steel, which can
cause kickback and damage to the chain.
Always keep to the side of the falling tree. When the
tree starts to fall, shut off the engine, withdraw the bar
and walk away on the pre-planned escape path.
Watch out for falling limbs.
WARNING!
Be extremely careful with partially fallen trees which
are poorly supported.
When the tree hangs or for some other reason does
not fall completely, set the saw aside and pull the
tree down with a cable winch, block and tackle or
tractor. If you try to cut it down with your saw, you
may be injured.
Sectioning Method
WARNING!
Felling a tree that has a diameter greater than the
length of the guide bar requires use of either the
sectioning or plunge-cut method. These methods
are extremely dangerous because they involve the
use of the nose of the guide bar and can result in
kickback.
Only properly trained professionals should attempt
these techniques.
Forthesectioningmethod(g.24)maketherstcut
with the guide bar fanning in toward the hinge. Then,
using the bumper spike as a pivot, reposition the saw
for the next cut. Avoid repositioning the saw more than
necessary.
When repositioning for the next cut, keep the guide bar
fully engaged in the kerf to keep the felling cut straight.
If the saw begins to pinch, insert a wedge to open the
cut. On the last cut, do not cut the hinge.
Plunge-Cut Method
Timber having a diameter more than twice the length of
the guide bar reauires the use of the plunge-cut meth-
od before making the felling cut.
First, cut a large, wide notch. Make a plunge cut in the
center of the notch.
The plunge cut is made with the guide bar nose. Begin
the plunge cut by applying the lower portion of the
guidebarnosetothetreeatanangle(g.25).Cutuntil
depth of the kerf is about the same as the width of the
guidebar(g.26).Next,alignthesawinthedirection
in which the recess is to be cut. With the saw at full
throttle,inserttheguidebarinthetrunk(g.27).

WARNING!
There is an extreme danger of kickback at this point.
Extra caution must be taken to maintain control
of the saw. To make the felling cut, follow the
sectioningmethoddescribedpreviously(g.29).
If you are inexperienced with a chain saw plunge-
cutting should not be attempted. Seek the help of a
professional.
Limbing
Limbing is removing the branches from a fallen tree.
WARNING!
There is an extreme danger of kickback during the
limbing operation. Do not work with the nose of the
bar. Be extremely cautious and avoid contacting the
log or other limbs with the nose of the guide bar.
Do not stand on a log while limbing it - you may slip
or the log may roll.
Start limbing by leaving the lower limbs to support
thelogofftheground(g.30).Alwayscutfromthe
top of the limb.
Do not underbuck freely hanging limbs. A pinch
may result or the limb may fall, causing loss of
control. If a pinch occurs, stop the engine and
remove the saw, by lifting the limb.
WARNING!
Be extremely cautious when cutting limbs under
tension. The limbs could spring back toward the
operator and cause loss of control of the saw or
injury to the operator.
Bucking
Bucking is cutting a log into sections.
WARNING!
1. When bucking, do not stand on the log. Make
sure the log will not roll down-hill. If on a slope,
standontheup-hillsideofthelog(seeg.31).
Watch out for rolling logs.
WARNING!
2. Cut only one log at a time.
WARNING!
3. Shattered wood should be cut very carefully.
Sharpsliversofwoodmaybecaughtandung
in the direction of the operator of the saw.
WARNING!
4. When cutting small logs, use a sawhorse
(g.32).Neverpermitanotherpersontohold
the log. Never hold the log with your leg or foot.
At the end of the cut the weight of the chain
saw will cause it to swing through, since it is no
longerheldbythecut.Holditrmlytocontrol
this.

Maintenance and Repair
Never operate a chain saw that is damaged, improperly
adjusted or not completely or securely assembled.
Follow the maintenance and repair instructions in the
appropriate section of this manual.
WARNING !
Always stop the engine and make sure that
the chain is stopped before commencing any
maintenance or repair work or cleaning the saw.
Allow the chain saw to cool off before doing any
maintenance work (burn hazard)!
When the chain saw is hot, do not cover it (with a
tarp, blanket, newspaper or the like).
Let the chain saw cool down before putting it in a
storage case or vehicle.
Chain saws with catalytic converter take longer to
cool down!
Do not attempt any maintenance or repair work
not described in this manual. Have such work
performed by your MAKITA service shop only.
Maintaining and storing the saw
Keep the chain, bar and sprocket clean and lubricated;
replace worn sprockets or chains.
Keep the chain sharp. You can spot a dull chain when
easy-to-cut wood becomes hard to cut and burn marks
appear on the wood.
Keep the chain at proper tension. Tighten all nuts, bolts
and screws except the carburetor adjustment screws
after each use.
Keep spark plug and wire connection tight and clean.
Store saws in a high or locked place, away from
children.
The chain protection cover should always be put on.
WARNING!
5. Logs under strain require special attention to
preventthesawfrompinching.Therstcutis
made on the compression side to relieve the
stressonthelog(seeg.33,34).Thebucking
cut is then made as shown. If the saw pinches,
stop the engine and remove it from the log.
WARNING!
6. Only properly trained professionals should
work in an area where the logs, limbs and roots
aretangled(i.e.ablowdownarea,g.35).
Working in blowdown areas is extremely
hazardous.

Checking the chain tension
The tension of the chain is correct if the chain rests against
the bottom side of the guide bar and can still be easily turned
by hand.
While doing so the chain brake must be released.
Check the chain tension frequently - new chains tend to get
longer during use!
When checking the chain tension the engine must be
switched off.
NOTE:
It is recommended to use 2-3 chains alternatively.
In order to guarantee uniform wear of the guide bar the bar
should be turned over whenever replacing the chain.
Retightening the saw chain
Loosen the nuts (2) about one turn with the universal
wrench.
Raise the tip of the guide bar a little and turn the chain
tensioning screw (4) to the right (clockwise) until the saw
chain is again up against the bottom edge of the guide bar
(see circle).
While keeping the tip of the guide bar raised, tighten the nuts
(2) again with the universal wrench.
