You can often make adjustments and repairs described
here. For other repairs, have the trimmer serviced by an
authorized service dealer.
SPOOL REPLACEMENT
NEW PREWOUND SPOOL
See Figures 24 and 25.
If replacing string only, refer to “String Replacement” later in
this manual.
Use only monofilament string. Use original manufacturer's
replacement string for best performance.
String Diameter:
CS30 - .080 in. (2.0 mm)
SS30 - .095 in. (2.4 mm)
BC30 - .095 in. (2.4 mm)
1. Stop the engine, disconnect the spark plug wire. Hold
the string head and unscrew the spool retainer.
To remove the spool retainer:
Turn the spool retainer counterclockwise for models
CS30.
Turn the spool retainer clockwise for models SS30 and
BC30.
2. Remove the empty spool from the string head. Keep the
spring attached to the spool.
3. To install the new spool, make sure the two strings are
captured in the slots opposite each other on the new
spool. Make sure the ends of each string is extended
approximately 6 in. (152 mm) beyond each slot.
4. Thread the strings into the eyelets in the string head.
Carefully push the spool into the string head (gently pull
the strings to the outside if necessary). When the spool
is positioned in the string head, grasp the strings and
pull sharply to release them from the slots in the spool.
5. Push down and turn the spool counterclockwise until it
no longer turns. Hold the spool down and rotate clock-
wise a small amount. Release the spool. The spool
should be locked down in the string head. If not, hold
down and rotate until locked.
WARNING:
Use only original manufacturer's replacement parts,
accessories and attachments. Failure to do so can
cause poor performance, possible injury and may void
your warranty.

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.
