Anleitung Zusammenfassung
Retension if necessary – see “Tensioning the Saw Chain”. Chain at operating temperature: The chain stretches and begins to sag. The drive links must not come out of the bar groove – the chain may otherwise jump off the bar. Retension the chain – see “Tensioning the Saw Chain” ! Always slacken off the chain after finishing work. The chain contracts as it cools down. If it is not slackened off, it can damage the crankshaft and bearings. After long period of full-throttle operation Allow engine to run for a short while at idle speed so that engine heat can be dissipated by flow of cooling air. This protects engine-mounted components (ignition, carburetor) from thermal overload. After finishing work : Slacken off the chain if you have retensioned it at operating temperature during cutting work. The chain contracts as it cools down. If it is not slackened off, it could damage the crankshaft and bearings. Storing your saw for a short period: Wait for engine to cool down. To avoid condensation, fill the fuel tank and keep the machine in a dry place, well away from sources of ignition, until you need it again. Storing for a long period: See “Storing the Unit”! Oil QuantityControl * 001BA157 KN1 Different quantities of oil are required for different bar lengths, types of wood and cutting techniques. : : : : Use the adjusting screw (1) (on underside of machine) to vary the oil feed rate as required. E = Ematic position, medium oil flow rate - turn adjusting screw to " E" (Ematic position) To increase oil feed – turn adjusting screw clockwise. To reduce oil feed – turn adjusting screw counter-clockwise. Your chain must always be wetted with a film of lubricant. * Special accessory MS 441 C English / USA Taking Care of Guide Bar Air Filter System 2 001BA119 KN1 3 3 : Turn the bar over – every time you sharpen the chain and every time you replace the chain – this helps avoid one-sided wear, especially at the nose and underside of the bar. : Regularly clean the oil inlet hole (1) , the oilway (2) and the bar groove (3) . : Measure groove depth – with scale on filing gauge* – in area used most for cutting. Chain Pitch Minimum type groove depth Picco 3/8“ P 0.20" (5.0 mm) Rapid 1/4“ 0.16" (4.0 mm) Rapid 3/8“; 0.325“ 0.24" (6.0 mm) Rapid 0.404“ 0.28" (7.0 mm) If groove depth is less than specified: : Replace the guide bar. The drive link tangs will otherwise scrape along the bottom of the groove – the cutters and tie straps will not ride on the bar rails. The air filter system can be adapted to suit different operating conditions by simply installing a choice of filters. 1 137BA011 KN Standard wire mesh filter (1) (green) for normal normal operating conditions and winter operation. HD filter (2) (black) for dry and very dusty work areas. * see “Guide to Using this Manual” MS 441 C English / USA STIHL filters (standard and HD) have a long service life when kept in a dry condition. : Always use STIHL filters in dry condition. Dirty air filters reduce engine power, increase fuel consumption and make starting more difficult. Removing the Air Filter : Use the combination wrench to open the fasteners ( 1) in the direction of the arrows. : Remove the carburetor box cover ( 2). : Loosen the nut ( 3) in the direction of the arrow. : Pull off the filter. Cleaning Standard Filter 137BA013 KN If there is a noticeable loss of engine power: : Knock the filter out on the palm of your hand or blow it out with compressed air from the inside outward. In case of stubborn dirt or sticky filter fabric: : Wash the filter in a fresh, nonflammable solution (e.g. warm soapy water) and then dry. : Do not impregnate the standard filter with oil. Always replace a damaged filter. : Refit the filter. MS 441 C English / USA Cleaning HD Filter 2 1 176BA005 KN176BA006 KN176BA007 KN 2 1 If there is a noticeable loss of engine power: : Clean the felt prefilter (1) . After cleaning the prefilter several times: : Separate the filter components. : Knock the HD filter (2) out on the palm of your hand and blow it out with compressed air from the inside outward. In case of stubborn dirt or sticky filter fabric: : Wash filter with STIHL universal cleaner or in a fresh, non-flammable solution (e.g. warm soapy water). : Rinse the filter, from the inside outward, under a low-pressure water jet – do not use a high- pressure washer. : Dry all parts of the filter. Do not expose to high temperatures. : Fit the felt prefilter (1) over the HD filter (2) - note correct installed position (see ilustration). : Install HD filter (with felt prefilter) and carburetor box cover. : Check carburetor setting and readjust if necessary. The felt prefilter helps protect the HD filter and thus extends its useful life. For this reason the felt prefilter should be replaced at more frequent intervals than the HD filter. Always replace a damaged filter. MS 441 C English / USA Motor Management Adjusting the Carburetor Exhaust emissions are controlled by the design of the fundamental engine pa...
