To install the spool retainer:

Turn the spool retainer clockwise for model CS30. Turn
the spool retainer counterclockwise for models SS30 and

position. Push the spool retainer down while pulling on
string(s) to manually advance the string and to check for
proper assembly of the string head.

Turn the spool retainer counterclockwise for models CS30.
Turn the spool retainer clockwise for models SS30 and
BC30.
 Remove the spool from the string head.
NOTE: Keep the spring attached to the spool. Remove
any old string remaining on the spool.
 Cut two pieces of string, each being approximately 9 ft.
(2.7 m) long.
 Insert the first string into the anchor hole in the upper part
of the spool. Wind the first string around the upper part of
the spool counterclockwise, as shown by the arrows on
the spool. Place string in the slot on upper spool flange,
leaving about 6 in. (152 mm) extended beyond the slot.
Do not overfill. After winding the string, there should be
at least 1/4 in. (6 mm) between the wound string and the
outside edge of the spool.
 Repeat above step with second string, using the bottom
part of spool. Do not overfill.
 Replace the spool and the spool retainer. Refer to “Spool
