English / USA Storing the Machine Checking and Replacing Chain Sprocket For periods of about 3 months or longer: : Drain and clean the fuel tank in a well ventilated area. : Run engine until carburetor is dry, this helps prevent the carburetor diaphragms sticking together. : Remove the saw chain and guide bar, clean them and spray with corrosion inhibiting oil. : Thoroughly clean the unit, pay special attention to the cylinder fins and air filter. : If you use a biological chain and bar lubricant, e.g. STIHL BioPlus, completely fill the chain oil tank. : Store the unit in a dry and high or locked location, out of the reach of children and other unauthorized persons. Replace the chain sprocket after using two Oilomatic chains. Replace sooner if the wear marks on the sprocket are deeper than approx. 0.02 in (0.5 mm) since this would reduce the life of the chain. You can use a special reference gauge* to check the depth of the wear marks on sprockets. It is best to use two chains in rotation with one sprocket. Before removing the chain sprocket Remove the chain sprocket cover, chain and guide bar. Disengage the chain brake: Pull the hand guard back towards the front handle. 143BA042 KN 001BA086 KN : Use a screwdriver to remove the E-clip. : Pull the washer, spur sprocket and needle cage off the crankshaft. Clean the crankshaft stub and needle cage and lubricate with STIHL grease*. : Reassemble with a new spur sprocket. After fitting the clutch drum, rotate it about one half turn to engage the oil pump drive. : Refit washer and E-clip on the crankshaft. Use only original STIHL chain sprockets to ensure correct operation of the chain brake. * See "Guide to Using this Manual" * See "Guide to Using this Manual" 38 MS 191 T
