8. Rewind Starter
8.1 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.
In such a case it is sufficient to apply
a few drops of a standard solvent-
based degreasant (containing no
chlorinated or halogenated
hydrocarbons) to the rewind spring.
Carefully pull out the starter rope
several times and allow it to rewind
until its normal smooth action is
restored.
Before installing, lubricate the
rewind spring and starter post with
STIHL special lubricant, b 14.
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.
