Change location to start the engine (at least 3 meters away from the place of refuelling). ­ Only use the string trimmer in good lighting and visibility. During the winter season beware of slippery or wet areas, ice and snow (risk of slipping). ­ Never climb up trees to perform cutting operation with the string trimmer. Foreign particles may damage the nylon cutting head and can cause dangerous kick-backs. ­ Before commencing cutting, the nylon cutting head must have reached full working speed. Perform this cutting work by swinging the string trimmer evenly in half-circles from right to left (similar to using a scythe). ­ The condition of the trimmer also of the shoulder strap must be checked before commencing work. ­ Turn off the engine and remove the spark plug connector when replacing, and also when cleaning the nylon cutting head. ­ Operate the string trimmer with as little noise and contamination as possible. If your skin comes in contact with these substances repeatedly and for an extended period of time, it will desiccate. Fuel and oil mixture The engine of the String trimmer is a high-efficiency two-stroke engine. In case no such fuel is available, you can use fuel with a higher octane value. This will not affect the engine, but may cause poor operating behaviour. To obtain optimum engine operation and to protect your health and the environment, only unleaded fuel should be used!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 to use specified two-stroke engine oil at mixture ratio of 50:1 to protect the environment. In addition, a long service life and a reliable operation with a minimum emission of exhaust gases is guaranteed. It is absolutely essential to observe a mixture ratio of 50:1 (specified 2-stroke engine oil), as otherwise reliable function of the String trimmer cannot be guaranteed. The correct mixture ratio: Gasoline : Specified two-stroke engine oil = 50 : 1 or Gasoline : Other manufacturer's two-stroke engine oil = 25 : 1 recommended NOTE: For preparing the fuel-oil mixture first mix the entire oil quantity with half of the fuel required, then add the remaining fuel. Thoroughly shake the mixture before filling it into the String trimmer tank. [. . . ] ⷠCheck the nylon cutting head for damage and make sure it is firmly mounted. ⷠCheck that there is sufficient difference between idling and engagement speed to ensure that the nylon cutting head is at a standstill while the engine is idling (if necessary, reduce idling speed). If under idling conditions the tool should still continue to run, consult your nearest Authorized Service Agent. Clogging of the element (1) may sometimes make it difficult or impossible to start up the engine or increase the engine speed. [. . . ]
