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

SPOOL REPLACEMENT

EZ LINE™ TAP ADVANCE SYSTEM

NEW PREWOUND SPOOL

See Figures 10 and 11.

If replacing string only, refer to “String Replacement” later in this manual.

Use only .080 in. (2.0 mm) diameter monofilament string. Use original manufacturer's replacement string for best performance.

1.Stop the engine, disconnect the spark plug wire. Hold the string head and unscrew the spool retainer. Turn counterclockwise.

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.

6.Make sure the string head and the spool retainer are installed on the drive shaft by turning the retainer clockwise to tighten.

7.Pull the strings again to rotate the spool into cutting 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.
