108BA014 KN 001BA126 KN English Tensioning the rewind spring N Make a loop in the starter rope and use it to turn the rope rotor six full revolutions in the direction of the arrow. N Hold the rotor steady. Pull out and straighten the twisted rope. N Release the rope rotor. N Release the rope slowly so that it winds onto the rotor. The starter grip must sit firmly in the rope bushing. If the grip droops to one side: Add one more turn on the rope rotor to increase spring tension. When the starter rope is fully extended it must still be possible to rotate the rotor another half turn. If this is not the case, the spring is overtensioned and could break: N Take one turn of the rope off the rotor. Models with Easy2Start: N Fit the spring housing, driver and washer on the starter post. N Use circlip pliers to carefully install the circlip in the starter post groove. All versions N Fit the fan housing on the crankcase. N Install the shroud - see "Shroud". Replacing a broken rewind spring N Removing the rope rotor The bits of spring might still be under tension and could fly apart when you take them out of the housing. To reduce the risk of injury, wear face protection and work gloves. N Carefully remove the parts of the spring. N Lubricate the new spring with a few drops of non-resinous oil. N Place the new spring with frame in position in the fan housing - the anchor loop must engage the lug in the housing. N Apply suitable tools (screwdriver, punch, etc.) to the recesses and push the spring into its seat in the fan housing - it slips out of the frame in this process. N Take the frame out of the fan housing. N Reinstall the rope rotor, tension the rewind spring, fit the fan housing and secure it in position. 46 MS 171, MS 181, MS 181 C, MS 211, MS 211 C
