Rewind spring in position Tensioning the rewind spring
First remove the rope rotor and take
out any spring particles which are
still in the fan housing. The replace-
ment spring is supplied ready for
assembly and is held together by a
wire strap. It should be lubricated with
a few drops of non-resinous oil before
installation.
Position the rewind spring in the rope
rotor so that the outer spring loop
engages on the lug in the fan housing.
The wire strap is pushed off the spring
during this operation.
If the spring comes out and uncoils
during installation, refit it in the fan
housing in the clockwise direction,
starting with the outer end and working
inward. Then refit the rope rotor.
Wind the starter rope clockwise onto
the rope rotor until the starter grip is
about 20 cm (8") away from the fan
housing. Grip rope next to rotor and
use it to rotate rotor two full turns
clockwise. This tensions the rewind
spring. Now hold rope rotor firmly in
position, straighten out twisted rope
and pull it out of fan housing. Let go
of rope rotor and slowly release rope
so that it winds onto the rotor.
The rewind spring is correctly ten-
sioned when the starter grip sits
firmly in the fan housing without
hanging to one side. If this is not the
case, tension rewind spring a further
turn. When the rope is fully extended
it must still be possible to rotate the
rope rotor at least another half turn
before maximum spring tension is
reached. If this is not so, take off one
turn of the rope.
If the starter rope action becomes
very stiff and it rewinds very slowly or
not completely, it can be assumed
that the rewind starter is mechanically
in order but plugged with dirt.
At very low temperatures the oil on
the rewind spring may thicken and
cause the spring windings to stick to-
gether. This has a detrimental effect
on the operation of the rewind starter.
In such a case it is sufficient to apply
a little paraffin to the rewind spring.
Then pull out starter rope carefully
several times until its normal smooth
action is restored. If clogged with dirt
or resin, the entire rewind starter
mechanism, including rewind spring,
must be removed from the machine.
Take special care when removing the
spring! Wash all parts in paraffin or
clean gasoline.
Lubricate the rewind spring and
starter post with oil when
reassembling the mechanism.
