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, 
b 12.
Carefully pull out the starter rope 
several times and allow it to rewind 
until its normal smooth action is 
restored.
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 parts, b 12.
Lubricate the rewind spring and 
starter post with STIHL special 
lubricant, see b 12, before 
installing.
