6.5 Tensioning the Rewind Spring
• Hold the starter grip firmly to
keep the rope tensioned.
• Let go of the rope rotor and slowly
release the starter grip so that the
rope winds itself onto the rotor.
• Fit the rewind spring in the
assembly tool in the counter-
clockwise direction, starting
outside and working inwards.
Note: The wooden assembly block
can be placed over the assembly
tool to simplify refitting.
• Slip the assembly tool with rewind
spring over the starter post.
• Make a loop in the starter rope.
• Grip the rope close to the rotor
and use it to turn the rope rotor
seven full turns clockwise.
Note: The rewind spring is correctly
tensioned when the starter grip sits
firmly in the rope guide bush without
drooping to one side. If this is not the
case, tension the spring by one
additional turn.
When the starter 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 the case, pull the rope out, hold
the rope rotor steady and take off
one turn of the rope.
Do not overtension the rewind
spring as this will cause it to break.
• Refit the fan housing.
• Push the rewind spring into the fan
housing and then remove the
assembly tool.
• Install the rope rotor - see 6.2.
• Hold the rope rotor steady.
• Pull out the rope with the starter
grip and straighten it out.
