Anleitung Zusammenfassung
: Hold the rotor steady. : Pull out and straighten the twisted rope. : Release the rotor. : Let go of rope slowly so that it winds onto the rotor. The starter grip must locate firmly in the rope guide bushing. If the grip droops to one side: Add one more turn on rope rotor to increase spring tension. When the starter rope is fully extended it must still be possible to rotate the rotor at least another half turn. If this is not the case, the spring is overtensioned and could break. : Take one turn of rope off the rotor. Replacing a broken rewind spring The bits of spring might still be under tension and could fly apart when you take them out of the housing. To reduce risk of injury, wear eye and face protection and work gloves. : Remove the rope rotor. : Use a screwdriver to carefully remove the spring housing ( 1) and remaining parts of the spring. : Lubricate the new spring with a few drops of non-resinous oil. : Place the new spring with spring housing in the starter cover. : Fit the rope rope, tension the rewind spring, fit the starter cover and screw it in position. For periods of about 3 months or longer: : Drain and clean the fuel tank in a well ventilated area. : Dispose of remaining fuel and cleaning solution properly in accordance with local environmental requirements. : Run engine until carburetor is dry – this helps prevent carburetor diaphragms sticking together. : Thoroughly clean the machine – pay special attention to the cylinder fins and air filter. : Store the machine in a dry, high or locked location – out of the reach of children and other unauthorized persons.
