1. For replacement line, use a diameter of .095in

housing to unhook the bottom cap.

line so that one half line is 4.7in.(12cm) shorter than
another half. And then, hook bended end in the slot of
the spool.

4. Wind up the line in the correct direction as indicated

on the spool.

5. Hook each end of the line in the slot on the edge of

the spool, and then put the ends through the eyelets
on the housing. Make sure that the spring and the
washers are in place.

line ends to release them from the slot.

7. Line up the slot on the bottom cap with the hook on

the housing, press the cap against the housing until it
