ADDITIONAL SAFETY RULES

1. Read the instruction manual in order to familiarize yourself with operation of the chain saw.

2. Before using the chain saw for the first time, arrange to have instruction in its operation. If this is not possible, at least practice cutting round timber on a trestle before beginning work.

3. The chain saw must not be used by children or young persons under 18 years of age. Young persons over 16 years of age may be exempted from this restriction if they are undergoing training under the supervision of an expert.

4. Working with the chain saw requires a high level of concentration. Do not work with the saw if you are not feeling fit and well. Carry out all work calmly and carefully.

5. Never work under the influence of alcohol, drugs or medication.

Proper use

1. The chain saw is intended solely for cutting wood. Do not use it for example to cut plastic or porous concrete.

2. Only use the chain saw for operations described in this instruction manual. Do not, for example, use it to trim hedges or for similar purposes.

3. The chain saw must not be used for forestry work, i.e. for felling and limbing standing timber. The chain saw cable does not provide the operator with the mobility and safety required for such work.

4. The chain saw is not intended for commercial use.

5. Do not overload the chain saw.

Personal protective equipment

1. Clothing must be close-fitting, but must not obstruct mobility.

2. Wear the following protective clothing during work:

• A tested safety helmet, if a hazard is presented

by falling branches or similar;

• A face mask or goggles;

• Suitable ear protection (ear muffs, custom or

mouldable ear plugs). Octave brand analysis upon request.

• Firm leather safety gloves;

• Long trousers manufactured from strong fabric;

• Protective dungarees of cut-resistant fabric;

• Safety shoes or boots with non-slip soles, steel

toes, and cut-resistant fabric lining;

• A breathing mask, when carrying out work

which produces dust (e.g. sawing dry wood).

Protection against electric shock

...................The chain saw must not be used in

1. Only plug the saw into earthed sockets in tested electrical circuits. Check that the system voltage matches that on the rating plate. Ensure that a 16 A line fuse is fitted. Saws used in the open air must be connected to a residual current-operated circuitbreaker with an operating current no higher than 30 mA.

...................Should the connecting cable be dam-

wet weather or damp environments, as the electric motor is not waterproof.

aged, withdraw the mains plug immediately.

Safe working practices

1. 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;

• The bar and the sprocket cover are fitted

correctly;

• The chain has been sharpened and tensioned

in accordance with the regulations;

• The mains cable and mains plug are

undamaged;

Refer to the “CHECKS “ section.

2. Always ensure in particular that the extension cable used is of adequate cross-section (see “SPECIFICATIONS”). When using a cable reel, wind the cable completely off the reel. When using the saw in the open air, ensure that the cable employed is intended for open-air use and is rated accordingly.

3. Do not operate the chain saw in the vicinity of flammable dust or gases, as the motor generates sparks and presents a risk of explosion.

4. Work only on firm ground and with a good footing. Pay particular attention to obstacles (e.g. the cable) in the working area. Take particular care where moisture, ice, snow, freshly cut wood or bark may make surfaces slippery. Do not stand on ladders or trees when using the saw.

5. Take particular care when working on sloping ground; rolling trunks and branches pose a potential hazard.

6. Never cut above shoulder height.

7. Hold the chain saw with both hands when switching it on and using it. Hold the rear handle with your right hand and the front handle with your left. Hold the handles firmly with your thumbs. The bar and the chain must not be in contact with any objects when the saw is switched on.

8. Clean the area to be cut of foreign objects such as sand, stones, nails, wire, etc. Foreign objects damage the bar and chain, and can lead to dangerous kickback.

9. Take particular care when cutting in the vicinity of wire fences. Do nut cut into the fence, as the saw may kick back.

10. Do not cut into the ground.

11. Cut pieces of wood singly, not in bunches or stacks.

12. Avoid using the saw to cut thin branches and roots, as these can become entangled in the chain saw. Loss of balance presents a hazard.

13. Use a secure support (trestle) when cutting sawn timber.

14. Do not use the chain saw to prise off or brush away pieces of wood and other objects.

15. Guide the chain saw such that no part of your body is within the extended path of the saw chain (see figure).

16. When moving around between sawing operations, apply the chain brake in order to prevent the chain from being operated unintentionally. Hold the chain saw by the front handle when carrying it, and do not keep your finger on the switch. Withdraw the mains plug when taking breaks or leaving the chain saw unattended. Leave the chain saw where it cannot present a hazard.

17. Withdraw the mains plug when taking breaks or leaving the chain saw unattended. Leave the chain saw where it cannot present a hazard.

Kickback

1. Hazardous kickback may arise during work with the chain saw. Kickback arises when the tip of the bar (in particular the upper quarter) comes into contact with wood or another solid object. This causes the chainsaw to be deflected in the direction of the operator.

• When bucking, keep clear of adjacent trunks. Always observe the bar tip.

• Use a trestle.

Safety features

1. Always check that that the safety features are in working order before starting work. Do not use the chain saw if the safety features are not working properly.

- Chain brake:

The chain saw is fitted with a chain brake which brings the saw chain to a standstill within a fraction of a second. It is activated when the hand guard is pushed forwards. The saw chain then stops within

0.15 s, and the power supply to the motor is interrupted.

- Run-down brake:

The chain saw is equipped with an run down brake which brings the saw chain to an immediate stop when the ON/OFF switch is released. This prevents the saw chain from running on when switched off, and thus presenting a hazard.

-The front and rear hand guards protect the

user against in jury from pieces of wood which may be thrown backwards, or a broken saw chain.

-The trigger lockout prevents the chain saw

from being switched on accidentally.

-The chain catcher protects the user against

injury should the chain jump or break.

2. In order to avoid kickback, observe the following:

• Never begin the cut with the tip of the bar.

• Never use the tip of the bar for cutting. Take particular care when resuming cuts which have already been started.

• Start the cut with the chain running.

• Always sharpen the chain correctly. In particular, set the depth gauge to the correct height (refer to “Sharpening the chain “ for details).

• Never saw through several branches at a time.

• When limbing, take care to prevent the bar from coming into contact with other branches.

Transport and storage

...................When the chain saw is not in use or

1. Carry the chain saw by the front handle only, with the bar pointing backwards.

2. Keep the chain saw in a secure, dry and locked room out of the reach of children. Do not store the chain saw outdoors.

is being transported, withdraw the mains plug and fit the scabbard supplied with the saw. Never carry or transport the saw with the saw chain running.

Maintenance

1. Withdraw the plug from the socket before carrying out any adjustments or maintenance.

2. Check the power cable regularly for damage to the insulation.

3. Clean the chain saw regularly.

4. Have any damage to the plastic housing repaired properly and immediately.

5. Do not use the saw if the switch trigger is not working properly. Have it properly prepared.

6. Under no circumstances should any modifications be made to the chain saw. Your safety is at risk.

7. Do not carry out maintenance or repair work other than that described in this instruction manual. Any other work must be carried out by MAKITA Service.

8. Only use original MAKITA replacement parts and accessories intended for your model of saw. The use of other parts increases the risk of accident.

9. MAKITA accepts no responsibility for accidents or damage should non-approved bars, saw chains or other replacement parts or accessories be used. Refer to the “Extract from the spare parts list “ for approved saw bars and chains.

First aid

...................Do not work alone. Always work
