STRING REPLACEMENT
See Figures 26, 27, and 28.
Use only monofilament string. Use original manufacturer's
replacement string for best performance.
String Diameter:
ZR30000 - .080 in. (2.0 mm)
ZR30002 - .095 in. (2.4 mm)
ZR30004 - .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
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.
