:
Carefully remove the parts of the old
spring from the starter cover and
rope rotor.
:
Insert the new rewind spring in the
rope rotor and, at the same time,
engage the outer spring loop in the
rotor’s recess – the wire retainer
slips off in this process.
If the spring pops out and uncoils,
refit it in the counterclockwise
direction, starting outside and
working inwards.
:
Go to "Installing the Rope Rotor".
Installing rope rotor with rewind
spring
:
Carefully unpack the new rope rotor
with rewind spring. The spring may
pop out if not handled with care –
risk of injury.
:
Lubricate the spring with a few
drops of non-resinous oil – see
"Special Accessories".
:
Go to "Installing the Rope Rotor".
Installing the Rope Rotor
:
Check dimension
a
for inner spring
anchor loop and bend it slightly if
necessary.
:
Coat rope rotor bearing bore with
non-resinous oil – see "Special
Accessories".
:
Slide the rotor onto the starter post –
turn it back and forth until the rewind
spring anchor loop (
8
)
engages.
:
Insert the screw (
5
) and tighten it
down securely.
:
Go to "Tensioning the Rewind
Spring".
Tensioning the Rewind Spring
:
Make a loop in the unwound
starter rope and use it to turn
the rope rotor
six
full revolutions
counterclockwise. Hold the rotor
steady – straighten the twisted rope
– release the rotor –
let go of rope slowly so that it winds
onto the rotor.
:
Check spring tension:
–
The starter grip must be firmly
seated in the rope guide bushing.
If the grip droops to one side: Add
one more turn on rope rotor to
increase spring tension.
–
When the starter rope is fully
extended it must be possible to
rotate the rotor another half turn. If
this is not the case, the spring is
overtensioned and
could break
.
Take one turn of rope off the rotor.
:
Go to "Fitting the Starter Cover".
