SAFETY WARNINGS

General power tool safety warnings

WARNING: Read all safety warnings, instruc-

tions, illustrations and specications provided

with this power tool. Failure to follow all instructions

listedbelowmayresultinelectricshock,reand/or

seriousinjury.

Save all warnings and instruc-

tions for future reference.

The term "power tool" in the warnings refers to your

mains-operated (corded) power tool or battery-operated

(cordless) power tool.

General chain saw safety warnings

1. Keep all parts of the body away from the saw

chain when the chain saw is operating. Before

you start the chain saw, make sure the saw

chain is not contacting anything. A moment of

inattention while operating chain saws may cause

entanglement of your clothing or body with the

saw chain.

2. Always hold the chain saw with your right

hand on the rear handle and your left hand on

the front handle. Holding the chain saw with a

reversedhandcongurationincreasestheriskof

personalinjuryandshouldneverbedone.

3. Hold the chain saw by insulated gripping sur-

faces only, because the saw chain may contact

hidden wiring. Saw chains contacting a "live"

wire may make exposed metal parts of the chain

saw "live" and could give the operator an electric

shock.

4. Wear eye protection. Further protective equip-

ment for hearing, head, hands, legs and feet is

recommended. Adequate protective equipment

willreducepersonalinjuryfromyingdebrisor

accidental contact with the saw chain.

5. Do not operate a chain saw in a tree, on a lad-

der, from a rooftop, or any unstable support.

Operation of a chain saw in this manner could

resultinseriouspersonalinjury.

6. Always keep proper footing and operate the

chain saw only when standing on xed, secure

and level surface. Slippery or unstable surfaces

may cause a loss of balance or control of the

chain saw.

7. When cutting a limb that is under tension, be

alert for spring back. When the tension in the

woodbresisreleased,thespringloadedlimb

may strike the operator and/or throw the chain

saw out of control.

8. Use extreme caution when cutting brush and

saplings. The slender material may catch the saw

chainandbewhippedtowardyouorpullyouo

balance.

9. Carry the chain saw by the front handle with

the chain saw switched o and away from your

body. When transporting or storing the chain

saw, always t the guide bar cover. Proper

handling of the chain saw will reduce the likelihood

of accidental contact with the moving saw chain.

10. Follow instructions for lubricating, chain

tensioning and changing the bar and chain.

Improperly tensioned or lubricated chain may

either break or increase the chance for kickback.

11. Cut wood only. Do not use chain saw for pur-

poses not intended. For example: do not use

chain saw for cutting metal, plastic, masonry

or non-wood building materials. Use of the

chainsawforoperationsdierentthanintended

could result in a hazardous situation.

12. Do not attempt to fell a tree until you have an

understanding of the risks and how to avoid

them.Seriousinjurycouldoccurtotheoperatoror

bystanders while felling a tree.

13. Causes and operator prevention of kickback:

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 sudden

reverse reaction, kicking the guide bar up and

back towards the operator.

Pinching the saw chain along the top of the guide

bar may push the guide bar rapidly back towards

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.

Kickback is the result of chain saw misuse and/or

incorrect operating procedures or conditions and

can be avoided by taking proper precautions as

given below:

•

Maintain a rm grip, with thumbs and

ngers encircling the chain saw handles,

with both hands on the saw and position

your body and arm to allow you to resist

kickback forces. Kickback forces can be con-

trolled by the operator, if proper precautions

are taken. Do not let go of the chain saw.

►Fig.1

12 ENGLISH

• Do not overreach and do not cut above

shoulder height. This helps prevent unin-

tended tip contact and enables better control

of the chain saw in unexpected situations.

• Only use replacement guide bars and saw

chains specied by the manufacturer.

Incorrect replacement guide bars and saw

chains may cause chain breakage and/or

kickback.

• Follow the manufacturer’s sharpening

and maintenance instructions for the saw

chain. Decreasing the depth gauge height

can lead to increased kickback.

14. Follow all instructions when clearing jammed

material, storing or servicing the chain saw.

Make sure the switch is o and the battery

pack is removed. Unexpected actuation of the

chainsawwhileclearingjammedmaterialor

servicingmayresultinseriouspersonalinjury.

Adjusting saw chain tension

CAUTION: Carry out the procedure of install-

ing or removing saw chain in a clean place free

from sawdust and the like.

CAUTION: Do not tighten the saw chain too

much. Excessively high tension of saw chain may

cause breakage of saw chain, wear of the guide bar

andbreakageoftheadjustingdial.

CAUTION: A chain which is too loose can

jump o the bar and it may cause an injury

accident.

OPERATION

Lubrication

CAUTION: Do not operate the chain saw when

the tank is empty. Replenish the oil in due time

before the tank is empty.

CAUTION: Prevent the oil from coming into

contact with the skin and eyes. Contact with the

eyes causes irritation. In the event of eye contact,

ush the aected eye immediately with clear

water, then consult a doctor at once.

CAUTION: Never use waste oil. Waste oil con-

tains carcinogenic substances. The contaminants

in waste oil cause accelerated wear of the oil

pump, the bar and the chain. Waste oil is harmful

to the environment.

NOTICE:

When the chain saw is used for the rst

time, it may take up to two minutes for the saw chain

oil to begin its lubricating eect upon the saw mech-

anism. Run the saw without load until it does so.

NOTICE:

When lling the chain oil for the rst time,

or relling the tank after it has been completely emp-

tied, add oil up to the bottom edge of the ller neck.

The oil delivery may otherwise be impaired.

NOTICE: Use the saw chain oil exclusively for

Makita chain saws or equivalent oil available in

the market.

NOTICE: Never use oil including dust and parti-

cles or volatile oil.

NOTICE: When pruning trees, use botanical oil.

Mineral oil may harm trees.

NOTICE: Before the cutting operation, make sure

that the provided oil tank cap is screwed in place.

Saw chain is automatically lubricated when the tool is in

operation. Check the amount of remaining oil in the oil

tank periodically through the oil inspection window.

►Fig.20: 1. Oil tank cap 2. Oil inspection window

Tolltheoil,performthefollowingsteps:

1. Clean the area around the oil tank cap thoroughly

to prevent any dirt from entering the oil tank.

2. Lay the chain saw on its side and remove the oil

tank cap.

3. Fill the oil tank with the oil. The proper amount of

oil is 150 ml.

4. Screwtheoiltankcaprmlybackinplace.

5. Wipe away any spilt chain oil carefully.

NOTE:Ifitisdiculttoremovetheoiltankcap,insert

17 ENGLISH

Working with the chain saw

CAUTION: The rst time user should, as a

minimum practice, do cutting logs on a saw-horse

or cradle.

CAUTION: When sawing precut timber, use a

safe support (saw horse or cradle). Do not steady

the workpiece with your foot, and do not allow

anyone else to hold or steady it.

CAUTION: Secure round pieces against

rotation.

CAUTION: Keep all parts of the body away

from the saw chain when the motor is operating.

CAUTION: Hold the chain saw rmly with

both hands when the motor is running.

CAUTION: Do not overreach. Keep proper

footing and balance at all times.

NOTICE: Never toss or drop the tool.

NOTICE: Do not cover the vents of the tool.

Bring the bottom edge of the chain saw body into

contact with the branch to be cut before switching on.

Otherwise it may cause the guide bar to wobble, result-

ingininjurytooperator.Sawthewoodtobecutbyjust

moving it down by using the weight of the chain saw.

►Fig.23

If you cannot cut the timber right through with a single

stroke:

Apply light pressure to the handle and continue sawing

and draw the chain saw back a little; then apply the

spikebumperalittlelowerandnishthecutbyraising

the handle.

►Fig.24

Bucking

1. Rest the bottom edge of the chain saw body on

the wood to be cut.

►Fig.25

2. With the saw chain running, saw into the wood

while using the rear handle to raise the saw and the

front one to guide it. Use the spike bumper as a pivot.

3. Continue the cut by applying slight pressure to

the front handle, easing the saw back slightly. Move

the spike bumper further down the timber and raise the

front handle again.

NOTICE: When making several cuts, switch the

chain saw o between cuts.

CAUTION: If the upper edge of the bar is used

for cutting, the chain saw may be deected in

your direction if the chain becomes trapped. For

this reason, cut with the lower edge, so that the

saw will be deected away from your body.

►Fig.26

When you cut a wood under tension, cut the pressured

side(A)rst.Thenmakethenalcutfromthetensioned

side (B). This prevents the bar from becoming trapped.

►Fig.27

Limbing

CAUTION: Limbing may only be performed by

trained persons. A hazard is presented by the risk

of kickback.

When limbing, support the chain saw on the trunk if possible. Do

not cut with the tip of the bar, as this presents a risk of kickback.

Pay particular attention to branches under tension. Do

not cut unsupported branches from below.

Do not stand on the felled trunk when limbing.

Burrowing and parallel-to-grain cuts

CAUTION: Burrowing and parallel-to-grain

cuts may only be carried out by persons with

special training. The possibility of kickback presents

ariskofinjury.

Perform parallel-to-grain cuts at as shallow an angle as

possible. Take an extra caution when carrying out the

cut as the spike bumper cannot be used.

►Fig.28

Felling

CAUTION: Felling work may only be per-

formed by trained persons. The work is hazardous.

Observe local regulations if you wish to fell a tree.

►Fig.29: 1. Felling area

— Before starting felling work, ensure that:

• Only persons involved in the felling operation

are in the vicinity;

• Any person involved has an unhindered path

of retreat through a range of approximately

45° either side of the felling axis. Consider

the additional risk of tripping over electrical

cables;

• The base of the trunk is free of foreign

objects,rootsandranches;

• Nopersonsorobjectsarepresentovera

distance of 2 1/2 tree lengths in the direction

in which the tree will fall.

— Consider the following with respect to each tree:

• Direction of lean;

• Loose or dry branches;

• Height of the tree;

• Natural overhang;

• Whether or not the tree is rotten.

— Consider the wind speed and direction. Do not

carry out felling work if the wind is gusting strongly.

—

Trimming of root swellings: Begin with the largest swell-

ings.Maketheverticalcutrst,thenthehorizontalcut.

— Stand to the side of the falling tree. Keep an area

clear to the rear of the falling tree up to an angle of

45° either side of the tree axis (refer to the “felling

area”gure).Payattentiontofallingbranches.

— An escape path should be planned and cleared

as necessary before cuts are started. The escape

path should extend back and diagonally to the rear

oftheexpectedlineoffallasillustratedingure.

►Fig.30: 1. Felling direction 2. Danger zone

3. Escape route

18 ENGLISH

When felling trees, follow the procedures below:

1. Cut a scarf as close to the ground as possible.

First make the horizontal cut to a depth of 1/5 -1/3 of the

trunk diameter. Do not make the scarf too large. Then

make the diagonal cut.

►Fig.31

NOTE: The scarf determines the direction in which

the tree will fall, and guides it. It is made on the side

towards which the tree is to fall.

2. Make the back cut a little higher than the base

cut of the scarf. The back cut must be exactly horizon-

tal. Leave approximately 1/10 of the trunk diameter

betweenthebackcutandthescarf.Thewoodbersin

the uncut trunk portion act as a hinge. Insert wedges

into the back cut in time.

►Fig.32

WARNING: Do not cut right through the bers

under any circumstances. The tree will otherwise

fall unchecked.

NOTICE: Only plastic or aluminum wedges may

be used to keep the back cut open. The use of

iron wedges is prohibited.

Carrying tool

Before carrying the tool, always apply the chain brake

and remove the battery cartridge from the tool. Then

attach the guide bar cover. Also cover the battery car-

tridge with the battery cover.

►Fig.33: 1. Guide bar cover 2. Battery cover

MAINTENANCE

CAUTION: Always be sure that the tool is

switched o and the battery cartridge is removed

before attempting to perform inspection or

maintenance.

CAUTION: Always wear gloves when perform-

ing any inspection or maintenance.

NOTICE: Never use gasoline, benzine, thinner,

alcohol or the like. Discoloration, deformation or

cracks may result.

To maintain product SAFETY and RELIABILITY,

repairs,anyothermaintenanceoradjustmentshould

be performed by Makita Authorized or Factory Service

Centers, always using Makita replacement parts.

Sharpening the saw chain

Sharpen the saw chain when:

•

Mealy sawdust is produced when damp wood is cut;

• Thechainpenetratesthewoodwithdiculty,even

when heavy pressure is applied;

• The cutting edge is obviously damaged;

• The saw pulls to the left or right in the wood.

(caused by uneven sharpening of the saw chain or

damage to one side only)

Sharpen the saw chain frequently but a little each time.

Twoorthreestrokeswithaleareusuallysucientfor

routine resharpening. When the saw chain has been

resharpened several times, have it sharpened in our

authorized service center.

Sharpening criteria:

WARNING: An excessive distance between

the cutting edge and depth gauge increases the

risk of kickback.

►Fig.34: 1. Cutter length 2. Distance between cutting

edge and depth gauge 3. Minimum cutter

length (3 mm)

— Allcutterlengthmustbeequal.Dierentcutter

lengths prevent the saw chain from running

smoothly and may cause the saw chain to break.

— Do not sharpen the chain when the cutter length

has reached 3 mm or shorter. The chain must be

replaced with new one.

— The chip thickness is determined by the distance

between the depth gauge (round nose) and the

cutting edge.

— The best cutting results are obtained with following

distance between cutting edge and depth gauge.
