Fuel

CAUTION:

This saw is powered by mineral-oil products (gasoline (petrol) and oil).

Be especially careful when handling gasoline (petrol). Avoid all flame or fire. Do not smoke (explosion hazard).

Fuel mixture

The engine of the chain saw is a high-efficiency two-stroke engine. It runs on a mixture of gasoline and two-stroke engine oil.

The engine is designed for unleaded regular gasoline with a min. octane value of 91 ROZ. In case no such fuel is available, you can use fuel with a higher octane value. This will not affect the engine.

Inorderto obtain an optimum engine output and to protect your health and the environment use unleaded fuel only. Gasoline which contens alcohol should not used in MAKITA products.

For lubricating the engine use a two-stroke engine oil (quality grade: TC-3), which is added to the fuel. The engine has been designed for use of MAKITA high-performance two-stroke engine oil and a mixture ratio '3only 50:l to protect the environment. In addition, a long service life and reliable oper- ation with a minimum emission of exhaust gases are ensured. MAKITAhigh-performancetwo-stroke engineoil is available in the following sizes to suit your individual requirements:

1I order number 980 008 607

100ml order number 980 008 606

In case MAKITA high-performancetwo-stroke engine oil is not available, it is urgently recommendedto use a mixture ratio of 40:l with other two-stroke engine oils, as otherwise optimum operation of the engine cannot be guaranteed.

The correct mixture ratio:

50:l when using MAKITA high-performancetwo-stroke en- gine oil, i. e. mix 50 parts gasoline with 1 part oil.

40:l when using other two-stroke engine oils, i. e. mix 40 parts gasoline with 1 part oil.

NOTE:

For preparingthe fuel-oil mixturefirst mix the entire oil quantity with half of the fuel required, then add the remaining fuel. Thoroughlyshake the mixture beforefilling it intothe chain saw tank.

Chain oil

Use an oil with adhesive additive for lubricating the chain and guide bar. The adhesive additive prevents the oil from being flung off the chain too quickly.

We recommendthe use of chain oil which is bio-degradable in order to protectthe environment.The use of bio-degradableoil may even be required by local regulations.

The chain oil BIOTOP sold by MAKITA is made of special vegetable oils and is 100% bio-degradable.BIOTOPhas been granted the "blue angel" (Blauer Umweltschutz-Engel) for being particularly environment-friendly (RAL UZ 48).

It is not wise to add more engine oil than specified to ensure safe operation. This will only result in a higher production of combus-tion residues which will pollute the environment and clog the exhaust channel in the cylinder as well as the muffler. In addition, fuel consumption will rise and perform- ance will decrease.

NOTE:

Fuel cannot be stored for an unlimited period of time. Buy only as much as will be consumed in 4 weeks. Use only approved and marked containers for transport and storage.

AVOID SKIN AND EYE CONTACT

Mineral oil products degrease your skin. If your skin comes in contact with these substances repeatedly and for an extended period of time, it will desiccate. Various skin deseases may result. In addition,allergic reactions are known to occur.

Eyes can be irritated by contact with oil. If oil comes into your eyes, immediately wash them with clear water.

If your eyes are still irritated, see a doctor immedi- ately!

BIOTOP chain oil is available in the following sizes: 1 I order number 980 008 610

5 I order number 980 008 611

Bio-degradableoil is stable only for a limited period of time. It should be used within 2 years from the date of manufacture (printed on the container).
