MAINTENANCE

STRING REPLACEMENT

See Figures 26 - 28.

Stop the engine and disconnect the spark plug wire. Hold the string head and turn the spool retainer clockwise to remove.

Remove the spool from the string head.

NOTE: Keep the spring attached to the spool. Remove any old string remaining on the spool.

Cut one piece of trimmer line 18 ft. long.

Find the middle of the string section. Loop the string around the hook in the center of the spool. Carefully wind the string in the direction indicated on the top of the spool. Nearing the end of the string, slide one end of the string into each slot of the spool. Do not overfill.

Replace the spool and the spool retainer. Refer to Spool Replacement earlier in this manual.

CLEANING THE EXHAUST PORT AND MUFFLER

NOTE: Depending on the type of fuel used, the type and amount of oil used, and/or your operating conditions, the exhaust port, muffler, and/or spark arrestor screen may become blocked with carbon deposits. If you notice a power loss with your gas powered tool, you may need to remove these deposits to restore performance. We highly recommend that only qualified service technicians perform this service.
