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 ZR30000.
Turn the spool retainer clockwise for models ZR30002 and ZR30004.
2.Remove the spool from the string head.
NOTE: Keep the spring attached to the spool. Remove any old string remaining on the spool.
3.Cut two pieces of string, each being approximately 9 ft. (2.7 m) long.
4.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.
5.Repeat above step with second string, using the bottom part of spool. Do not overfill.
6.Replace the spool and the spool retainer. Refer to “Spool Replacement” earlier in this manual.
