Rules for safe operation
0. Tree servi ce chain saw
NOTE
When replacing guide bar or saw chain, ask your ECHO dealer.
The saw is specially designed for tree service, i.e. for off-ground working in trees, and
when being used as such should only be used be trained operators.
One handed operation of the saw can be dangerous.
Be alert for the phenomena "skating" and "bouncing", greater risk from kickback.
Be cautious not to lose balance of your body due to "drop" at the end of a cut.
If working off the ground the operator must be trained in safe climbing techniques and
use of all recommended safety equipment such as harness, loops, strops, ropes and
karabiners for himself and for the saw.
When hoisting a chain sa w usin g a rope tied to a lifting hook f or oper ation on a tree, e nsure
that the lifting hook is not strained by excessive force.
General requirements
Operators of tree service chai n-saws wor king at h eight fro m a rope and harn ess s hould ne ver
work alone.
A ground worker trained in appropriate emergency procedures should assist them.
Operators of tree service chain-saws for this work should be trained in general safe climbing
and work positioning techniques and be properly equipped with harnesses, ropes, strops,
carabiners and other equipment for maintaining secure and safe working positions for both
themselves and the saw.
Preparing to use the saw in the tree
The chain-saw should be checked, fuelled, started and warmed up by the ground worker and
then switched off before it is sent up to the operator in the tree.
The chain-saw should be fitted with a suitable strop for attachment to the operator's harness:
Example of attachment of chain-saw to operator's harness
secure the strop around the attachment point on the rear of the saw;
provide suitable k arabiners to allow in direct (i.e. via the strop) and direc t attachment (i.e. at
the attachment point on the saw) of the saw to the operator's harness;
ensure the saw is securely attached when it is being sent up to the operator;
ensure the saw is secured to the harness before it is disconnected from the means of
ascent.
The ability to directly attach the saw to the harness reduces the risk of damage to equipment
when moving around the tree.
Always switch the saw off when it is directly attached to the harness.
Example of attachment of chain-saw to centre rear mid-point on harness
The saw should only be attached to the recommended attachment points on the harness.
These may be at mid-point (front or rear) or at the sides.
Where possible, attach the saw to centre rear mid-point to keep it clear of climbing lines and
to support its weight centrally down the operator's spine.
When moving the saw from any one attachment point to another, operators should ensure it
is secured in the new position before releasing it from the previous attachment point.
5
Using the chain-saw in the tree
An analysis of accidents with these saws during tree service operations shows the primary
cause as being inappropriate one-handed use of the saw.
In the vast majority of accid ents, operators f ail to adopt a secure work position that allows them
to hold both handles of the saw.
This results in an increased risk of injury due to
not having a firm grip on the saw if it kicks back,
a lack of contro l of the sa w such that it is m ore like ly to come into conta ct with cl imbing lin es
and the operator's body (particularly the left hand and arm), and
loss of control owing to an insecure work position and resulting in contact with the saw
(unexpected movement during operation of the saw).
1. Securing the work position for two-ha nded use
In order to allow the saw to be held with both hands, as a general rule operators should aim
for a secure work position in which they operate the saw at
hip level, when cutting horizontal sections, and
solar plexus level, when cutting vertical sections.
Example of redirection of the main line via supplementary anchor point
Where the operator is working close into vertical stems with low lateral forces on the work
position, then a good footing could be all that is needed to maintain a secure work position.
However, as operators move away from the stem, they will need to take steps to remove or
counteract the increasing lateral forces by, for example, a redirect of the main line via a
supplementary anchor point or using an adjustable strop direct from the harness to a
supplementary anchor point.
Example of temporary foot stirrup created from endless sling
Gaining a good footing at the work in g pos iti on c an be as si sted by the use of a temporary foot
stirrup created from an endless sling.
2. Starting the saw in the tree
When starting the saw in the tree, the operator should
apply the chain brake before star ting ,
hold the saw on either the left or right of the body when starting,
1. on the left side, hold the s aw with the left hand on th e front handle and thrust th e saw away
from the body while holding the pull starter cord in the right hand, or
2. on the right side, hold the saw with the right hand on either handle and thrust the saw
away from the body while holding the pull starter cord in the left hand.
The chain brake should always be engaged before lowering a running saw onto its strop.
Operators should alw ays check th at the saw has sufficient fu el before unde rtaking criti cal cuts.
6
3. One-hand use of the chain-saw
Operators should not use tre e service chain-saws one-handed when work pos ition is unsta ble
or in preference to a handsaw when cutting small diameter wood at the branch tips.
Tree service chain-saws should only be used one-handed where
operators cannot gain a work position enabling two-handed use, and
they need to support their working position with one hand, and
the saw is being used at full stretch, at right angles to and out of line with the operator's
body.
Example of one-handed chain-saw use
Operators should never
cut with the kickback zone at the tip of the chain-saw guide bar,
"hold and cut" sections, or
attempt to catch falling section s.
4. Freeing a trapped saw
It the saw become trapped during cutting, operators should
switch off the saw and att ac h it s ecurely to the tree inboard (i.e. towards the trunk side)
of the cut or to a separate tool line,
pull the saw from the kerf whilst lifting the branch as necessary,
if necessary, use a handsaw or second chain saw to release the trapped saw by cutting a
minimum of 30 cm away from the trapped saw.
Whether a handsaw or a chain-saw is used to free a trapped saw, the release cuts should
always be outboard (toward the tips of the branch), in order to prevent the saw being taken
with the section and further complicating the situation.

1. General precautions
Operator's manual
Read the operator's manual for your chain saw carefully.
Be thoroughly fa milia r wit h the chai n saw' s c ontrols and how to us e the cha in sa w pr operly .
Failure to follow instructions could lead to personal injury.
If you have any questions or problems, please contact your ECHO dealer.
Physical condition
Do not operate a chain saw when you are fatigued or under the influence of al cohol or
drugs.
You should be in good phys ical and mental health in order to ha ndle your chain saw safe ly.
Errors in judgement or execution can be serious or fatal.
If you have any physical condition which strenuous work could worsen, check with your
physician before using a chain saw.
Do not operate when ill or fatig ued , or under the influence of any substance or medicatio n
which could affect your vision, dexterity or judgement.
Personal equipment
CAUTION
Stuffing ears with cotton is not recommended.
Always wear approved goggles to protect your eyes.
Wood chips, dust, sn app ing branches and other debris can be thrown by t he c utting chain
into the operator's facial area.
Goggles may also offer limited protection in the event of the cutting chain hitting the
operator in the eye area.
If conditions warrant that a ventilated face shield be worn, goggles must be worn
underneath it.
ECHO advises wearing hearing protection at all times.
If not followed, heari ng loss can occur.
You should reduce th e risk of he aring da ma ge by wea ring eit her "hea dset" type pro tectors
or ear plugs which are approved by an authorized organization.
All persons who make part of thei r living using cha in saws sh ould be tes ted peri odical ly
for hearing deterioration.
Always wear a cap or hat when working with a chain saw.
A safety hard hat is highly recommended when felling or working under trees, or when
objects can fall on you.
Wear heavy duty, non -sl ip glo ves fo r impro ved g rip, and also for p rotect ion aga inst c old
and vibration.
Safety tip shoes or boots with non-slip sole should be worn.
Never wear loose clothing, unbuttoned jackets, flared sleeves and cuffs, scarves,
tie-strings, neckties, cords, chains, jewellery, etc. which could snag the saw chain or
underbrush.
Clothing should be of sturdy, protective material.
It should be snug-fitting to resist snagging, but roomy enough for freedom of movement.
Trouser legs should not be flared or cu ffed, and should be either tucked into the boot tops
or trimmed short.
Safety vests, leg chaps and logger's pants of ballistic material are available.
It is the operator's responsibility to wear such additional protection if conditions warrant it.
Never operate a chain saw when you are alone.
Arrange to have someone remain within calling distance in case you need help.

Fuel
DANGER
Petrol and fuel are extremely flammable.
If spilled or ignited by ignition source, it can cause fire and serious injury or
property damage.
Extreme caution is required when handling petrol or fuel.
After refuelling, tighten fuel cap firmly and check for leakage.
In case of fuel leakage, repair before starting operation since there is a danger of
fire.
1. Oil tank cap
2. Fuel tank cap
A: Loosening direction
B: Tightening direction
Use an appropriate type of fuel container.
Bring an extinguisher or shovel in case of fire.
Despite the precautions which can be taken, operating a chain saw, or just working in the
forest, presents dangers.
Do not smoke or bring flame or sparks near to fuel supplies.
The fuel tank may be under pressure.
Always loosen the fuel cap and wa it for pres sure to be equalized before removing the cap.
When fuel tank cap o r o il ta nk c ap is dif ficult to re mo ve b y fin gers, put the s tarter h andle
into the groove of cap and turn it anticlockwise.
Fill the fuel tank outdoors over bare ground and install the fuel cap securely.
Do not pour fuel indoors.
Wipe any spilled fuel off the unit.
Never refuel while the engine is still hot, or fuel a running engine.
Do not store the unit with fuel in its tank, because a fuel leak could start a fire.
9
Starting engine
DANGER
Do not drop start the chain saw, drop s tart puts chain saw in an i nsecure pos ition and
can result in injury.
Start the chain saw in a correct ma nner.
Move the chain saw at least 3 m from the fuelling point before starting the engine.
Do not allow other pe rsons to be near the ch ain saw when you are starting or cutti ng with
the chain saw.
Keep bystanders and animal s out of the work area.
Do not let anyone hold wood for you to cut.
Do not start cutting until you ha ve a clear wor k area, secure footi ng and a plan ned retreat
path from the falling tree.
Before you start the engine, make sure that the saw chain is not contacting anything.
Keep the handles dry, clean, and free of oil or fuel mi xture.
Operate the chain saw only in well-ventilated areas.
Exhaust gas, oil mist (from chain saw lubrication) or saw dust is harmful to health.
When starting the chain saw pl ace the unit on a flat ground and hold the front handle with
left hand and hold firm ly the rear end of rea r handle with right kne e and pull starter ha ndle
with right hand.
Transportation
1. Guide bar cover
When transporting your chain saw, use the appropriate guide bar cover.
Carry the chain saw with the engine st opped, the guide ba r and saw chain to the rear, and
the silencer away from your body.
10
2. Kickback safety precautions
DANGER
Kickback safety precaution for cha in saw use r s: kick bac k may occu r when the nose
or tip of the guide bar tou ches an object or when the wood cl oses in and pinch es t he
saw chain in the cut.
In some cases, ti p contact may ca use a lightni ng-fast revers e reaction, ki cking the gui de
bar up and back toward the operator (this is called a rotational kickback).
Pinching the saw chai n along the top of the guid e bar may push th e guide bar rapidl y back
toward the operator (this is called a linear kickback).
Either or these react ions may cause you to lose control of the saw and come in contact
with the moving chain, which could result in serious personal injury.
As a chain saw user, you should take several steps to keep your cutting jobs free from
accident or injury.
With a basic understanding of kickback, you can reduce or eliminate the element of
surprise.
Sudden surprise contributes to accidents.
Understand that rota tional kic kback is preventable by keeping an unshiel ded bar nose fro m
touching an object or the ground.
Do not operate a chain saw with one hand!
Serious injury to the operator, helpers or bystanders may result from one-handed
operation.
For proper control, always use two hands when operating a chain saw, one of which
operates the trigger.
Otherwise, this can result in the chain saw "skating" or skidding, which can result in
personal injury due to loss of control.
Keep a good firm grip on the saw which both hands, with the right hand on the rear
handle and the left hand on the front handle, when the engine is running.
Use a firm grip with thumbs and fingers encircling the chain saw handles.
A firm grip will help you reduce kickback and maintain control of the saw.
Two hands must be used to control the saw at all times.
Do not overreach or cut above chest height.
Make sure that the area in which you are cutting is free from obstructions.
Do not let the bar nose contact a log, branch, or any other obstruction which could be hit
while you are operating the saw.
Cutting at high engine speeds may reduce the likelihood of kickback.
But cutting at part-thro ttle or low en gine spe eds may b e preferabl e to co ntrol the ch ain saw
in tight situations and may als o reduc e the lik el iho od of kic kb ac k.
Follow manufacturer's sharpening and maintenance instructions for the saw chain.
Use only replacement guide bars and chains specified by the manufacturer, or the
acceptable equivalents of these guide bars and chains.
11
3. Other safety precautions
Vibration and cold
It is believed that a condition called Raynaud's Phenomenon, which affects the fingers of
certain individuals, may be brought about by exposure to cold and vibration.
Accordingly, your ECHO chain saw has shock mounts designed to reduce the intensity of
vibration received through the handles.
Exposure to cold and vibration may cause tingling and burning followed by loss of colour and
numbness in the fingers.
We strongly recommend you take the following precautions because the minimum exposure
which might trigger the ailment is unknown.
Keep your body warm, especially the head and neck, feet and ankles, and hands and
wrists.
Maintain good blood circulation by performing vigorous arm exercises during frequent
work breaks and also by not smoking.
Limit the number of hours of chain saw operation.
Try to fill a part of each work day with jobs other than chain sawing.
If you experience disco mfort, re dness and s well ing of th e finge rs, foll owed by white ning
and loss of feeling, consult your physician before further exposing yourself to cold and
vibration.
Repetitive stress injuries
It is believed that over-using the muscles and tendons of the fingers, hands, arms and
shoulders may cause soreness, swelling, numbness, weakness and extreme pain to the
areas just mentioned.
To reduce the risk of repetitive stress injury, do the following:
Avoid using your wrist in a bent, extended or twisted position.
Instead, try to maintain a straight wrist position.
Also, when grasping, use your whole hand, not just the thumb and index finger.
Take periodic breaks to minimize repetition and rest your hands.
Reduce the speed and force in which you do the repetitive movement.
Do exercises to strengthen the han d and arm muscles.
See a doctor if you feel tingling, numbness or pain in the fingers, hands, wrists or arms.
Relative to EU directive "Vibration"
EU Directive "Vibration" (2002/44/EC) was designed to protect people from safety and health
risks arising from mechanical vibration of a machine by enforcing employers to limit a
standardized 8 hour daily vibration exposure level, A(8).
Any person or organization that employs a person to operate a machine has to take the A(8)
value into account whe n letting the person us e it.
Mechanical vibration values (equivalent vibration value) of this machine, which shall be used
as a guide to simplify the calculation of A(8) value, are as follows:

Machine conditions
WARNING
Do not modify a chain saw in any way.
Only attachments and parts supplied by ECHO or expressly appr oved by ECHO for
use with the specific ECHO chain saw models are authorized.
Although certain unauthorized attachments are useable with the ECHO powerhead,
their use may, in fact, be extremely dangerous.
Do not operate a ch ain saw that is damaged, imp roperly adjus ted, or not comple tely and
securely assembled.
Do not operate the chain saw with a loose or defective silencer.
Be sure that the saw chain stops moving when the throttle control trigger is released.
Cutting
CAUTION
Do not touch h ot surfaces of cylinder cover and sil encer after you used the chain saw .
Do not operate a chain s aw in a tree u nle ss you have been specifically trained to do s o.
Keep all parts of your body away from the saw chain when the engine is running.
Use extreme caution when cutting smal l-size brush and saplings because slender
material may catch the saw chain and be whipped toward you or pull you off balance.
Stay on the uphill side when bucking or limbing logs which might roll when cut.
When cutting a limb that is under tens ion, be alert for spri ng-back so that you will no t be
struck by the limb or chain saw when the tension in the wood fibres is released.
Cutting while on a ladder is extremely dangerous because the ladder can slip and your
control of the chain saw is limited.
Working aloft should be left to professionals.
Keep both feet on the ground.
Do not work from off-the-ground positions.
Stop the engine before setting the chain saw down.
Wood practices
Operating a chain sa w safely requires a chain saw in proper working order, sound
judgement, and knowledge of the methods which should be applied in each cutting
situation.
Do not let any person use your saw unl ess he has read this op erator' s manua l and fully
understands its instructions.
Use your saw only to cut wood or wood products.
Do not cut solid metal, sheet metal, plastics or any non-wood materials.
Services
All chain saw service operations, other than items listed in the operator's manual
maintenance instructi ons , sho uld be perform ed by co mpe t en t servic e personnel.
(For example, if an i mprop er tool is us ed to hold th e f lywheel in ord er to remo ve the clutch,
structural damage to the flywheel could occur and subsequently could cause the flywheel
to burst.)

Chain lubricant
Proper lubrication of the chain while in operation minimizes friction between the chain,
the guide bar and sprocket and also clutch components such as needle bearing and
clutch assembly.
Use ECHO genuine chain oil or ECHO recommended chain oil sp ecially formulated for ba rs
and chains for proper lubrication.
These oils contain tackifiers, anti-aging and anti-oxidizing agents.
Consult your ECHO dealer for the proper chain oil.
Never use waste or reclaimed oil to avoid various malfunctions on oil system, clutch
system, chain and guide bar.
Lubrication problems caused by the use of improper oil will void the warranty.
Especially, vegetable based chain oil quickly turns to resin and adheres to oil pump,
chain, guide bar, clutch needle bearing and clutch assembly.
It causes malfunctions and shorten product life.
Flush chain oil sy stem wit h miner al or chem ical based c hain oi l after us e, if it is requ ired to
use vegetable oil due to local / municipal rule or any other reason.
For a short time emergency operation, fresh SAE 10W-30 motor oil can be used.

Checking chain tension
WARNING
Make sure that the engine is shut off when checking chain tension.
NOTE
Always loosen clutch cover nut before turning the chain tension adjuster, otherwise the
clutch cover and tensioner will be damaged.
Chain tension should be checked frequently during work and corrected if necessary.
Tension the chain as tight as possible, but so it can still be pulled easily along the bar by
hand.
Chain lubrication test
Hold the chain just above a dry surface and open the throttle to half speed for 30
seconds.
A thin line of "thrown" oil should be seen on the dry surface.
Pre cutting test
Familiarize yourself with your chain saw before you start actual cutting.
For this purpose it may be wise to practice by cutting some small logs or limbs several
times.
Do not allow either people or animals into the work area.
Multiple operators - Keep a safe distance between two or more operators when working
together simultaneo usl y.
20
Correct use of chain brake
DANGER
Kickback motion is very hazardous.
If the tip of the bar touches wood or the like, the guide bar kicks back in an instant.
The chain brake reduces the possibility of injury due to kickback.
Always check that chain brake works properly before use.
NOTE
For practice, while cutting a small tree, push the front guard forward to engage the
brake.
At all times, confirm whether the brake works properly before each task.
If the chain brake is clogged with wood chips, function of the brake deteriorates a little.
Always keep the device clean.
Do not increase engine revolutions while the chain brake is engaged.
Chain brake is used in emergencies.
Do not use it unless absolutely necessary.
When using throttle latch at starting, keep the chain brake in position.
And after starting the engine, release the brake immediately.
Never test the brake in an area where petrol fumes are present.
Chain brake
The chain brake's function is to stop chain rotation after a kickback.
It neither prevents nor reduces kickback.
Do not depend on the chain brake for protection against kickba ck.
Even with a chain brake, depen d on your own go od sens e and prop er cut ting met hods ju st as
though there were no chain brake.
Even with normal use and p roper mai ntenan ce, the re spons e time o f the b rake ma y lengt hen.
The following may interfere with the brake's ability to protect the operator:
Saw wrongly held too close to operator's body.
Kickback time may be too fast even for a perfectly maintained brake to work in time.
The operator's hand may not be in position to contact the hand guard.
Brake will not be tripped.
Lack of proper mainte nance length ens the brake's s topping time, ma king it less ef fective.
Dirt, grease, oil, pitch, etc. getting into the working parts of the mechanism may lengthen
the stopping time.
Wear and fatigue of the activating brake spring, and wear of the brake / clutch drum and
pivot points may lengthen the brake's stopping time.
A damaged hand guard and lever may render the brake inoperative.
21
Checking the brake function of the brake
1. Place the chain saw on the ground.
2. Hold the handle with both hands and accelerate the engine to high speed by using the
throttle trigger.
3. Operate the chain brake by turning your left wrist against the front hand guard whilst
gripping the front handle.
4. The chain stop immediately.
5. Release the throttle trigger.
If the chain does not stop immediately, take the saw to your ECHO dealer to repair.
Release the chain brake
When front hand guard is fully pulled towards the operator, chain brake is released.
Non-manual chain brake
IMPORTANT
When checking the ope rati on of the non-manual chain brake, use a s oft su rfac e s ubstance
like wood to provide the impact so the saw chain is not damaged.
1). End of the guide bar may be placed at the height about 40 cm.
2). Rear handle should be gripped lightly with the right handle.
The non-manual chain brake stops the operation of the saw chain in such a manner that the
kickback action produced at the end of the guide bar non-manually actuates the chain brake.
To make sure that the non-manual chain brake operates properly, proceed as follows:
1. Stop the engine of th e chain saw.
2. Operate the front and rear handles with hands (grip them lightly), so that the guide bar
may be placed at the height of about 40 cm as shown in Fig.
3. Softly detach the left hand from the front handle, and touch the end of the guide bar
against the wood or the like placed below so that the machine receives an impact.
(* at this time the rear handle should be gripped lightly with right hand)
4. The impact is transferred to the brake lever, which actuates the chain brake.
22
Cutting instruction
DANGER
Do not let the nose or tip of the guide bar touch anything while engine is running to
avoid kick back.
General
In all circumstances the operation of the chain saw is a one-man job.
It is difficult at times to take care of your own safety, so don't assume the responsibility for a
helper as well.
After you have learned the basic techniques of using the saw, your best aid will be your own
good common sense.
The accepted way to hold the saw is to stand to the left of the saw with your left hand on the
front handle so you can operate the throttle trigger with your right index finger.
Before attempting to fell a tree, cut some small logs or limbs.
Be thoroughly familiar with the controls and the responses of the saw.
Start the engine, see that is running properly.
Squeeze the trigger to open the throttle wide open, then start the cut.
It is not necessary to press down hard to make the sa w cut.
If the chain is properly sharpened, the cutting should be relatively effortless.
Pushing the saw too hard will slow the engine and cutting will actually be more difficult.
Some material may adversely affect the housing of your chain saw.
(Example: palm tree acid, fertilizer etc.)
To avoid housing deterioration carefully remove all packed saw dust around clutch and guide
bar area and wash with water.
23
Felling a tree
A falling tree can seriously damage anything it may hit - a car, a house, a fence, a power-line
or another tree.
There are ways to make a tree fall where you want it, so first decide where that is!
Before cutting, clear the area around the tree.
You will need good footing while working and you should be able to work the saw without
hitting any obstacles.
Next select a path of retreat.
When the tree begins to fall you should retreat away from the direction of fall at a 45-degree
angle and at least 3 m from the trunk to avoid the trunk kicking back over the stump.
Begin the cut on the side to which the tree is to fall.
o
Notch: 1/3 of diameter and 30
Back cut: 2.5 to 5 cm higher
Uncut hinge wood: 1/10 of diameter
Cut a notch approximately 1/3 of the way into the tree.
The position of this notch is important since the tree will try to fall "into" the notch.
The felling cut is made on the side opposite the notch.
Make the felling cut by placing spiked bumper 2.5 cm to 5 cm above the bottom of the notch
and stop cutting at approximately 1/10 of diameter to the inner edge of the notch in order to
leave the uncut portion of the wood as a hing e.
1. Notch cuts
2. Back cut
3. Wedges (when room)
4. Fall
A: Leave 1/10 of diameter hinge
Do not try to cut through to the notch with the felling cut.
The remaining wood between the notch cut and felling cut will act as a hinge when the tree
falls, guiding it in the desired direction.
When the tree starts to fall, stop the engine, pla ce the saw on t he ground and m ake your retrea t
quickly.
to 45o angle
Fell big tree.
1. Notching cuts
2. Draw-across method
3. Back cut
4. Draw-across method
5. Felling cuts
A: Wedges
To fell big trees with a diameter exceeding twice the bar length, start the notching cuts from
one side and draw the saw through to the other side of the notch.
Start the back cut on one side of the tree with the spiked bumper engaged, pivoting the saw
through to form the desired hinge on that side.
Then remove the saw for the second cut.
Insert the saw in the first cut very carefully so as not to cause kickback.
The final cut is made by drawing the saw forward in the cut to reach the hinge.
24
Limbing
WARNING
Limbing in the proximity of power line can result in electrocution.
Always switch off power supply before starting operation.
CAUTION
Don't saw above chest height.
Limbing a fallen tree is much the same as bucking.
Never remove a limb from a tree while it is supporting your weight.
Be careful of the tip touching other limbs.
Always use both hands.
Don't cut with the saw overhead or the bar in a vertical position.
If the saw should kickback, you may not have good enough control to prevent possible injury .
Know how limb is stressed
1. Leave supporting limbs till last.
2. Slide support logs under trunk.
Even when limbing, use of the spiked bumper makes it easy to control the chain saw and
lessens kickback.
Bucking
CAUTION
Stay on the uphill side of logs.
Bucking is the sawing of a log or fallen tree into smaller pieces.
There are a few basic rules which apply to all bucking operations.
Keep both hands on the handles at all times.
Support logs if possible.
When cutting on a slope or hillside, always stand uphill.
No standing on log.
25
Tension and compression in timber
WARNING
Never use throttle latch for cutting jobs.
CAUTION
If you have misjudge d the effects of tens ion and compression , and cut from the w rong
side, the timber will pinch the guide bar and chain, trapping it.
Racing the engine with the chain jammed will burn out your clutch.
If the chain should become jam me d and the saw can not be removed from the cut do
not force it out.
Stop the saw, force a wedge into the cut to open it up.
Never force the saw when it is jammed.
Do not force the saw into the cut.
A dull chain is unsafe and will cause excessive wear to the cutting attachments.
A good way to tell when the chain is dull is when fine saw dust comes out instead of
chips.
1. Hinge
2. Opened
3. Closed
A length of timber lying on the ground will be subject to tension and compression, depending
at which points the major support is.
When timber is supported at its ends the compression side is at the top and the tension side
is at the bottom.
To cut between these support points, make the first cut downwards approximately 1/3rd the
timber diameter.
The second cut is made upwards and should meet the first cut.
Heavy stress
4. 1/3 diameter. To avoid split.
5. Weakening cut to finish.
When the timber i s su pported at one end o nly, make the f irst cut upw ards appro xima tely 1 /3rd
the timber diameter.
The second cut is made downwards and should meet the first cut.
Overbuck
6. Down
7. Unsupported end
Underbuck
8. Up
9. Wedge
Make angled cut when one section may settle against the other.

Saw chain maintenance
WARNING
Switch off the engine before sharpening the chain.
Always wear gloves when working on chain.
CAUTION
The following faults will increase the risk of kickback considerably.
1) Top plate angle too large
2) File diameter too small
3) Depth gauge too large
NOTE
These angles are referred to as Oregon 25AP, 91PX and Carlton N1C-BL saw chains.
For other branded saw chain, follow it's chain manufacturer's instruction.
Properly filed cutters are shown below.
A: Top plate angle N1C-BL; 35°, 25AP and 91PX; 30°
B: Top plate cutting angle N1C-BL; 60°, 25AP and 91PX; 55°
C: Depth gauge N1C-BL; 0.56 mm, 25AP and 91PX; 0.65 mm
D: Parallel
1. Left hand cutter
2. Tie strap
3. Right hand cutter
4. Depth gauge
5. Drive link
6. Rivet
Never operate a chain saw with a dull or damaged chain.
If the chain requires excessive pressure to cut or produces dust instead of wood chips then
inspect the cutters for damage.
When sharpening the chain the objective will be to maintain the same angles and profiles
throughout its life as when it was new.
Inspect th e chain for damage or wear every time you refuel your chain saw.
29
Sharpening
In order to file the chain correctly you need: round file and file holder, flat file and a depth
gauge tool.
By using the correct file size (4.0 mm Round file) and a file holder, it is easier to receive a
good result.
Consult your ECHO dealer for correct sharpening tools and sizes.
1. Lock the chain - push the front hand guard forward.
To rotate the chain - pull the front hand guard against front handle.
2. Your chain will have alternative left and right hand cutters.
Always sharpen from the inside out.
3. Keep the angle lines of the file holder parallel to the line of the chain and file the cutter
back until the damaged area (side plate and top plate) has been removed.
4. Hold the file horizontally.
5. Avoid touching the tie straps with the file.
6. Sharpen the most dama ged cutter first and th en take all the othe r cutters back to the same
length.
7. The depth control determines the thickness of wood chip produced and must be
maintained correctly throughout the chain life.
8. As the cutter length is reduced, the depth control height is altered and must be reduced.
9. Position the depth gauge, and file off any of the depth control which protrudes.
10. Round off the front of the depth control to allow smooth cutting.
11. Drive link serves to remove sawdust from the groove of the guide bar.
Therefore, keep the lower edge of the drive link sharp.
When setting of the chain is finished, soak it in oil and wash away filings completely before
using.
When the chain has been fi led on the ba r, suppl y suffic ient oi l to it, and rotate the cha in sl owly
to wash away the filings before using again.
If the chain saw is operate d with filing s clogged in the groove , the saw chai n and the guid e bar
will be damaged prematurely.
If the saw chain b ecomes soil ed with res in for inst ance, clean it with kero sene and s oak it in o il.
