REWIND STARTER

6.1

Routine Maintenance

If the action of the starter rope becomes
very stiff and the rope rewinds very slowly or
nor 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.
Then carefully pull out the starter rope
several times and allow it to rewind until its
normal smooth rewind until its normal
smooth action is restored.
If clogged with dirt or pitch, the entire starter
mechanism, includ ing 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 installing.

Rope Rotor/Pawls

Removing spring clip
Removing rope rotor
Troubleshooting chart - see 2.4.
The fan housing has to be removed for
access to the starter mechanism - see 5.1.5.
Relieve tension of rewind spring:
- Pull out the starter rope to a
length of approx. 30 cm (1 ft)
and hold the rope rotor steady.
- Catch the starter rope between the rope
guide bush and the rope rotor and pull it
out.
- While still holding the rope rotor steady,
take three full turns off the rope rotor.
- Pull out the rope with the starter grip and
then let go off the rope rotor.
Note: The rope rotor will spin back and thus
relieve the tension on the rewind spring. The
rewind spring will not be under tension if
the starter rope is broken.
- Use a screwdriver or suitable pair of
pliers to carefully remove the spring clip
from the starter post.
- Take the washer and rope rotor with
pawls off the starter post.
- Remove the pawls and check to see if
they are in good condition, replace if
necessary.
- Replace the broken or worn starter rope
- see 6.3.
Installing the rope rotor
- Coat the bore in the rope rotor with
STIHL special lubricant (see 12.2). Fit
the rotor on the starter post so that the
inner spring loop slides into the lug on
the rotor.
Note: Check that the spring loop has
engaged by turning the rope rotor slightly
and letting it go - it must spin back.
- Coat the pegs of the pawls with graphite
grease, see 12.2, and fit the pawls.
- Fit the washer and install the spring clip
in the starter post groove.
Note: Make sure the spring clip engages
on the pawl guide pegs and points them in
the clockwise direction.
- The spring clip must be treated very
carefully. If it is bent during disassembly
or assembly, the rewind starter might
malfunction.
- Tension the rewind spring - see 6.5.
