PRESENTATION Spark plug The engine spark plug is hidden under the ignition cable shoe. When performing service, it is important that the engine cannot start accidentally. For this reason, always remove the ignition cable shoe from the spark plug. To avoid pulling the cable, the cable shoe is equipped with a special handle; see the illustration. Type of spark plug, see "Technical data". Service instructions, see "Maintenance/Ignition system". Muffler The engine muffler is equipped with a heat protective cowling. Nonetheless, it still becomes hot when the engine is running. Avoid touching the muffler when it is warm. Risk for burns. Oil dipstick The dipstick for the crankcase oil reservoir is located on the front of the engine. Refill the engine oil in the hole where the dipstick fits. When checking the oil level, the dipstick should not be screwed in. The machine should be parked on even ground with the engine stopped. Never run the engine without the dipstick in place. Certain engines have electronic oil level guards. They stop the engine and prevent restarting if the level becomes too low. Yet you should not rely entirely on the level guard; rather you should check the oil using the dipstick. For normal use, we recommend SAE 10W-30-weight engine oil service SF-SG; see also the chapter "Lubrication/Engine oil". Oil drainage The drainage screw for the crankcase oil reservoir is located on the front of the engine. IMPORTANT INFORMATION Used engine oil is a health hazard and legislation prohibits disposal on the ground or in nature; it should always be disposed of at a workshop or appropriate disposal location. Avoid skin contact; wash with soap and water in case of spills. OFF ON Engine switch The engine switch stops the engine. The illustration shows the switch in the OFF position (short circuited electrical system). To start the engine, the switch must be first set to the ON position. 16 - English 8011-027 8011-020 8011-021 8011-026
