Safety precautions for chain saw operators
Additional safety precautions
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.
c) Always operate the chain saw with both hands.
WARNING!
Read and follow all safety precautions in the
Owner’s and Safety 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 Owner’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 significantly reduced kickback potential
are available.
The following additional safety precautions should be
observed by all users of chain saws:
1. Do not operate a chain saw when you are fatigued.
2. Use safety footwear; snug-fitting clothing;
protective gloves; and eye, hearing, and head
protection devices.
3. Use caution when handling fuel. Move the chain
saw at least 10 feet (3 m) from the fueling point
before starting the engine.
4. Do not allow other persons to be near the chain
saw when starting or cutting with the chain saw.
Keep bystanders and animals out of the work
area.
5. Do not start cutting until you have a clear work
area, secure footing, and a planned retreat path
from the falling tree.
6. Keep all parts of your body away from the saw
chain when the engine is running.
7. Before you start the engine, make sure that the
saw chain is not contacting anything.
8. Carry the chain saw with the engine stopped, the
guide bar and saw chain to the rear, and the
muffler away from your body.
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. This
contact may abruptly stop the saw chain and in
some cases may cause a lightning fast reverse
reaction, kicking the guide bar up and back towards
the user, or push the guide bar back towards the
operator. Kickback may cause you to lose control
of the saw.
As a chain saw user, you can take several steps to
reduce the risk of a kickback and potential injury.
A. With a basic understanding of kickback, you
can reduce or eliminate the element of surprise.
It is a sudden surprise that contributes to
accidents.
B. Keep a good firm grip on the saw with both
hands, your right hand on the rear grip and
your left hand on the tubular handle, when the
engine is running. Use a firm grip with thumbs
and fingers encircling the chain saw handles.
A firm grip can neutralize kickback and help
you 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 the log, branch,
or any other obstructions which could be hit
while you are operating the saw.
D. Do not overreach or cut above shoulder height.
E. Follow manufacturer’s sharpening and main-
tenance instructions for the saw chain.
F. Only use replacement bars and chains speci-
fied by the manufacturer or the equivalent.
4
9. Do not operate a chain saw that is damaged, is
improperly adjusted, or is not completely and
securely assembled. Be sure that the saw chain
stops moving when the throttle control trigger is
released.
10. Shut off the engine before setting it down.
11. Use extreme caution when cutting small size
brush and saplings because slender material may
catch the saw chain and be whipped towardyou
or pull you off balance.
12. When cutting a limb that is under tension be alert
for springback so that you will not be struck when
the tension on the wood fibers is released.
13. Keep the handles dry, clean, and free of oil or fuel
mixture.
14. Operate the chain saw only in well-ventilated
areas.
15. Do not operate a chain saw in a tree unless you
have been specifically trained to do so.
16. All chain saw service, other than the items listed in
the Owner’s Manual maintenance instructions,
should be performed by MAKITA. (For example, if
improper tools are used to remove the flywheel or
if an improper tool is used to hold the flywheel in
order to remove the clutch structural damage to
the flywheel could occur and could subsequently
cause the flywheel to burst.)
17. When transporting your chain saw, use the chain
protection cover.
18. Low kickback bars and low kickback chains are
designed to reduce the risk of kickback injury. Ask
your MAKITA dealer about these devices.

WARNING!
Minors should never be allowed to use a chain
saw.
Bystanders, especially children and animals should
not be allowed in the area where a chain saw is in
use (fig. 1).
Never let the saw run unattended.
Store it in a locked place away from children. Fill
the fuel tank to 7/8 th full (see storing the saw).
Do not lend your chain saw without this Owner’s
and Safety Manual. Be sure that anyone using
your saw understands the information given.
Contact of the guide bar tip with
any object should be avoided!
Tip contact may cause the guide
bar to move suddenly upward
and backward, which may cause
serious injury!
Always use two hands when
operating the chain saw!

WARNING !
Prolonged use of chain saws exposing the operator
to vibrations may produce Whitefinger disease
(Raynaud’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 Whitefinger disesase, however, they
reduce this danger considerably. Nevertheless,
continual and regular users should observe their
hands and fingers and in case of any abnormal
symptoms, seek medical advice immediately.
5
Proper clothing
The saw
Clothing must be sturdy and snug-fitting, but allow
complete freedom of movement. Avoid loose-fitting
jackets, scarfs, neckties, jewelry, flared or cuffed pants,
or anything that could become entangled with the saw
or brush. Wear overalls or jeans with a reinforced
cutting resistant insert (fig. 3).
Protect your hands with gloves when handling saw
and saw chain. Heavy-duty, nonslip gloves improve
your grip and protect your hands.
Parts of the chain saw: illustrations and description of
parts see page 16.
WARNING !
Never modify a chain saw in any way. Only
attachments supplied by MAKITA or expressly
approved by MAKITA for use with the specific 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 B 175.1-1991 chain saw safety standard.
The use of the saw
Transporting the chain saw
3
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.
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 muffler.
4
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 (fig. 4).
Wear protective helmet,
eye and ear protection!
6
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.
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).
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 fixed 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 (fig. 6).
5
WARNING!
Gasoline is an extremely flammable fuel. Use
extreme caution when handling gasoline or fuel
mix. Do not smoke or bring any sparks or flame
near the fuel (fig. 5).
Fueling instructions
Fuel your chain saw in well ventilated areas or outdoors. 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 (fig. 5a).
6
6a
Place the chain saw on firm 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 firmly grasp the front handle with
your left hand (fig. 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 semithrottle 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.
10 feet
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 fingers and
may damage the starter mechanism.

Important adjustments
WARNING!
At correct idle speed, chain should not turn. For directions to adjust idle speed, see the appropriate
section of this Manual.
Do not use a saw with incorrect idle speed adjustment. 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
adjusting the chain tension.
Working conditions
Wrap your fingers tightly around the handles, keeping
the handles cradled between your thumb and forefinger (fig. 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.
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.
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 firmly 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.
8
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!
Do not cut any material other than wood or
wooden objects.
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 (fig. 8). Such objects may be flung
off, damage the saw chain or cause the saw to
kickback.
7
8
9
In order to keep control of your saw, always maintain
a firm foothold. Never work on a ladder, in a tree or on
any other insecure support. Never use the saw above
shoulder height (fig. 9).
10
Position the chain saw in such a way that your body is
clear of the cutting attachment whenever the engine
is running (fig. 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.
11
Kickback:
Kickback occurs when the upper quadrant of the bar
nose contacts a solid object in the wood or is pinched
(fig. 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 fling the bar in an uncontrolled arc towards the operator.
12
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 (fig.12) or is incorrectly used to begin a
plunge or boring cut.
The greater the force of the kickback reaction, the
more difficult it becomes for the operator to control
the saw.
9
Many factors influence 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 (fig. 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.
13
To avoid kickback
The best protection from personal-injury that may
result from kickback is to avoid kickback situations:
1. Hold the chain saw firmly with both hands and
maintain a secure grip.
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 deflection 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 sufficient distance between the operator
and the bar to ensure that the chain brake has
sufficient time to activate and stop the chain
before potential contact with the operator.
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.
10
Pushback:
To avoid pull-in
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 frequently occurs when the top of the bar is used for
cutting (fig. 14).
14
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 (figures 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 fig. 15). The reaction of
the chain pulls the saw forward, causing the operator
to lose control.
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.
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.
15
WARNING!
Use extreme caution when cutting small size
brush and saplings which may easily catch the
chain and pull you off balance.
16
When felling in the vicinity of roads, railways and
power lines, etc., take extra precautions (see fig.
16). Inform the police, utility company or railway
authority before beginning to cut.
