22OILChain oilUse an oil with adhesive additive for lubricating the chain andguide bar. The adhesive additive prevents the oil from beingflung off the chain too quickly.We recommend the use of chain oil which is bio-degradable inorder to protect the environment. The use of bio-degradable oilmay even be required by local regulations.The chain oil BIOTOP sold by MAKITA is made of specialvegetable oils and is 100% bio-degradable. BIOTOP has beengranted the "blue angel" (Blauer Umweltschutz-Engel) for beingparticularly environment-friendly (RAL UZ 48).EBio-degradable oil is stable only for a limited period oftime. It should be used within 2 years from the date ofmanufacture (printed on the container).DOIL50:11.0 Us-gal. (3.7 l) 2.6 floz. (75 cm3)2.5 Us-gal. (9.4 l) 6.4 floz. (189 cm3)5.0 Us-gal.

Do not allow gasoline to come near flames,sparks or fire (explosion hazard).Fuel mixtureThis tool is powered by a high-performance air-cooled two-strokeengine. It runs on a mixture of gasoline and two-stroke engineoil.The engine is designed for unleaded regular gasoline with amin. octane value of 89 (R+M)/2. In case no such fuel is avail-able, you can use fuel with a higher octane value. This will notaffect the engine.In order to obtain an optimum engine output and to protectyour health and the environment use unleaded fuel only.To lubricate the engine, use a synthetic oil for two-stroke air-coo-led engines (quality grade: JASO FD or ISO-L-EGD), which hasto be added to the fuel. The engine has been designed for use ofMAKITA synthetic two-stroke engine oil and a mixture ratio ofONLY 50:1 to protect the environment. In addition, a long servicelife and reliable operation with a minimum emission of exhaustgases are ensured.MAKITA synthetic two-stroke engine oil (50:1) is available in thefollowing sizes to suit your individual requirements:2.6 floz. order number T-007456.4 floz. order number T-00739In case MAKITA synthetic two-stroke engine oil is not available,it is recommended to use a mixture ratio of 50:1 with othersynthetic two-stroke engine oils, as otherwise optimum opera-tion of the engine cannot be guaranteed.The correct mixture ratio:50:1 when using MAKITA synthetic two-stroke engine oil , i.e. mix 50 parts gasoline with 1 part oil.50:1 when using other synthetic two-stroke engine oils(quality grade JASO FD or ISO-L-EGD), i. e. mix 50 partsgasoline with 1 part oil.NOTE:For preparing the fuel-oil mixture first mix the entire oil quan-tity with half of the fuel required, then add the remaining fuel.Thoroughly shake the mixture before filling it into the chainsaw tank.It is not wise to add more engine oil than specifiedto ensure safe operation. This will only result in ahigher production of combustion residues whichwill pollute the environment and clog the exhaustchannel in the cylinder as well as the muffler. Inaddition, fuel consumption will rise and perform-ance will decrease.Storage:Fuels have a limited storage life. Fuel and fuel mixturesage through evaporation, especially at high tempera-tures. Aged fuel and fuel mixtures can cause startingproblems and damage the engine.Purchase only thatamount of fuel, which will be consumed over the nextfew months. At high temperatures, once fuel has beenmixed it should be used up in 6-8 weeks.Use only approved and marked containers fortransport and storage. Store fuel only in dry, cooland secure locations!AVOID SKIN AND EYE CONTACTMineral oil products degrease your skin. If your skincomes in contact with these substances repeatedlyand for an extended period of time, it will desiccate.Various skin deseases may result. In addition, allergicreactions are known to occur.Eyes can be irritated by contact with oil. If oil comes intoyour eyes, immediately wash them with clear water.If your eyes are still irritated, see a doctor immedi-ately!
