Replacing A Broken Rewind Spring; Tensioning The Rewind Spring - Stihl 015 Instruction Manual / Owners Manual

Replacing a broken rewind spring
First, remove the rope rotor as described before. The spare
spring is supplied ready for installation and secured with
a wire loop. Apply a few drops of nonresinous oil to the
spring before installing it. When installing, pass the outer
eye of the spring over the die-cast nose in the socket of
the hood and fmce the wire loop outward. If the rewind
spring should flip out when trying to insert it into the socket,
re-install it in clockwise direction from outside to inside.
Then reinstall the rope rotor.
Tensioning the rewind spring
Wind up the starter rope by turning the rotor in counter-
clockwise direction. Form a loop with the free portion of the
rope through the recess at the perimeter of the rotor and
turn it clockwise three to four times. If the rope is twisted,
pull it out through the gUide bore and untwist it. Release the
rope rotor cautiously and slowly slacken the starter rope
until it is wound up by the spring completely.
Then tension of the rewind spring is correct if the starter
grip rests firmly in the guide bore. If it does not, tension the
spring by another turn.
With the rope fully extended the rotor must rotate for at
least another half turn until maximum spring deflection is
reached.

Too much load on the spring will break it prematurelly.
