STRING REPLACEMENT
See Figures 20 and 21.
1.Stop the engine, disconnect the sparking plug wire. Hold the string head and unscrew the spool re- tainer. Turn clockwise.
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 2.7 m (9 ft) long.
4.Insert the first string into the anchor hole in the upper part of the spool. Wind the first string round the upper part of the spool anticlockwise, as shown by the arrows on the spool. Place string in the slot on upper spool flange, leaving about 152 mm (6 in) extended beyond the slot. Do not overfill. After winding the string, there should be at least 6 mm (1/4 in) 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.

BLADE PROTECTOR
See Figures 24.
Always place the blade protector on the blade when the unit is not in use. The blade protector has clips round the edges to snap over the blade and keep it in place. Wear gloves and be cautious when handling the blade.
NOTE: Always remove the blade protector before using the unit. If not removed, the blade protector could become a thrown object as the blade begins to turn.
