GENERAL SAFETY PRECAUTIONS If the muffler on your machine is fitted with a spark arrestor mesh this must be cleaned regularly. A blocked mesh will cause the engine to overheat and may lead to serious damage. WARNING! Mufflers fitted with catalytic ! converters get very hot during use and remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of fire! WARNING! The inside of the muffler contain ! chemicals that may be carcinogenic. Avoid contact with these elements in the event of a damaged muffler. Cutting equipment This section describes how to choose and maintain your cutting equipment in order to: • Reduce the risk of blade thrust. • Obtain maximum cutting performance. • Extend the life of cutting equipment. IMPORTANT! Only use cutting attachments with the guards we recommend! See the chapter on Technical data. Refer to the instructions for the cutting attachment to check the correct way to load the cord and the correct cord diameter. Keep the teeth of the blade correctly sharpened! Follow our recommendations. Also refer to the instructions on the blade packaging. Maintain the correct blade setting! Follow our instructions and use the recommended file gauge. WARNING! Bear in mind that: ! The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near combustible material! Locking nut A locking nut is used to secure some types of cutting attachment. WARNING! Always stop the engine before ! doing any work on the cutting attachment. This continues to rotate even after the throttle has been released. Ensure that the cutting attachment has stopped completely and disconnect the HT lead from the spark plug before you start to work on it. WARNING! Using an incorrect cutting ! attachment or an incorrectly sharpened blade increases the risk of blade thrust. Cutting equipment Grass blades and grass cutters are intended for cutting coarse grass. When fitting, tighten the nut in the opposite direction to the direction of rotation of the cutting attachment. To remove it, undo the nut in the same direction as the cutting attachment rotates. (CAUTION! The nut has a left-hand thread.) Tighten the nut using the socket spanner. A trimmer head is intended for trimming grass. General rules The nylon lining inside the locking nut must not be so worn that you can turn it by hand. The lining should offer a resistance of at least 1.5 Nm. The nut should be replaced after it has been put on approx. 10 times. Only use cutting attachments with the guards we recommend! See the chapter on Technical data. English - 9
