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.

Cordless 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 top handle and your left hand on

the front handle. Holding the chain saw with a

3. Hold the power tool by insulated gripping

surfaces only, because the saw chain may con-

tact hidden wiring. Saw chains contacting a "live"

wire may make exposed metal parts of the power

tool "live" and could give the operator an electric

shock.

4. Wear safety glasses and hearing protection.

Further protective equipment for head, hands,

legs and feet is recommended. Adequate protec-

body. When transporting or storing the chain

 Proper

handling of the chain saw will reduce the likelihood

of accidental contact with the moving saw chain.

9. Follow instructions for lubricating, chain ten-

sioning and changing accessories. Improperly

tensioned or lubricated chain may either break or

increase the chance for kickback.

10. Keep handles dry, clean, and free from oil and

grease. Greasy, oily handles are slippery causing

loss of control.

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

poses not intended. For example: do not use

chain saw for cutting plastic, masonry or non-

wood building materials. Use of the chain saw for



hazardous situation.

12. Causes and operator prevention of kickback:

Kickback may occur when the nose or tip of the



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

devices built into your saw. As a chain saw user,

you should take several steps to keep your cutting



Kickback is the result of tool misuse and/or incor-

rect operating procedures or conditions and can be

avoided by taking proper precautions as given below:

 

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 controlled by

the operator, if proper precautions are taken.

Do not let go of the chain saw.

Fig.1

• 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 bars and chains spec-

-

ment bars and 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.

13. Before starting work, check that the chain

saw is in proper working order and that its

condition complies with the safety regulations.

Check in particular that:

• The chain brake is working properly;

• The run-down brake is working properly;

 

correctly;

• The chain has been sharpened and ten-

sioned in accordance with the regulations.

14. Do not start the chain saw with the chain cover

being installed on it. Starting the chain saw with

the chain cover being installed on it may cause

the chain cover to thrown out forward resulting in

cal power lines. It may result in a malfunction or

breakdown of the tool or battery cartridge.

18. Keep the battery away from children.

SAVE THESE INSTRUCTIONS.

CAUTION: Only use genuine Makita batteries.

Use of non-genuine Makita batteries, or batteries that

have been altered, may result in the battery bursting

charger.

Tips for maintaining maximum

battery life

1. Charge the battery cartridge before completely

discharged. Always stop tool operation and

charge the battery cartridge when you notice

less tool power.

2. Never recharge a fully charged battery car-

tridge. Overcharging shortens the battery

service life.

3. Charge the battery cartridge with room tem-

perature at 10 °C - 40 °C (50 °F - 104 °F). Let

a hot battery cartridge cool down before

charging it.

4. When not using the battery cartridge, remove

it from the tool or the charger.

5. Charge the battery cartridge if you do not use

it for a long period (more than six months).

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.
