6. REWIND STARTER
6.1 Routine
Maintenance
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 paraffin (kerosine) to the
rewind spring.
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 special care
when removing the spring.
Wash all parts in paraffin or white
spirit.
Lubricate the rewind spring and
starter post with STIHL special
lubricant, see 12.2, before instal-
ling.
6.2 Rope Rotor/Pawl
Fan housing mounting
screws
Removing rope rotor:
Troubleshooting chart - see 2.4.
The fan housing has to be re-
moved for access to the starter
mechanism.
Relieving tension of rewind
spring:
- Pull out the starter rope to a
length of approx. 5 cm (2 - 3 in)
and hold the rope rotor steady.
- Take two turns of the rope off the
rotor.
- Pull out the starter grip and let go
of the rope rotor.
Note: The rope rotor will spin back
and relieve the tension of the rewind
spring. The rewind spring will not be
under tension if the starter rope is
broken.
- Remove the starter rope from the
rotor.
