Rewind starter

10.1

General

If the action of the starter rope
becomes very stiff and the rope
rewinds very slowly or not
completely, it can be assumed that
the starter mechanism is in order
but plugged with dirt. At very low
outside temperatures, the
lubricating oil on the rewind spring
may thicken and cause the spring
windings to stick together. This has
a detrimental effect on the function
of the starter mechanism.
To clean the rewind spring, it is
sufficient to apply a few drops of
commercially available solvent-
based degreasant not containing
any chlorinated or halogenated
hydrocarbons to the spring.
Carefully pull out the starter rope
several times and let it rewind until
its normal smooth action is restored.
Before installing, lubricate the
rewind spring and post with STIHL
special lubricant.
If clogged with dirt or pitch, the
entire starter mechanism, including
the rewind spring, must be removed
and disassembled. Take particular
care when removing the spring.
– Clean all components.
