MAINTENANCE
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.
You can often make adjustments and repairs described here. For other repairs, have the trimmer serviced by an authorized service dealer.

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 clockwise a small amount. Release the spool. The spool should be locked down in the string head. If not, hold down and rotate until locked.
