MAINTENANCE
WARNING:
Use only original manufacturer's replacement parts, accessories and attachments. Failure to do so can cause possible injury, poor performance and may void your warranty.
■You may make adjustments and repairs described here. For other repairs, have the trimmer serviced by an authorized servicing dealer.
■Consequences of improper maintenance may include excess carbon deposits resulting in loss of performance and discharge of black oily residue dripping from the muffler.
■Make sure all guards, straps, deflectors and handles are properly and securely attached to avoid the risk of personal injury.
6.Make sure the string head and the spool retainer are installed on the shaft by turning the retainer counter- 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.

See Figures 16 and 17.
If replacing string only, refer to “String Replacement” later in this manual.
Use only 2.4 mm (.095 in.) diameter monofilament string. Use the manufacturer's replacement string for best perfor- mance.
1.Stop the engine, disconnect the spark plug wire. Hold the string head and unscrew the spool retainer. Turn clockwise.
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 152 mm (6 in.) 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.
