MAINTENANCE
STRING REPLACEMENT
See Figures 16 - 19.
nStop 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 Trimlite and Trim n’ Edge.
Turn the spool retainer clockwise for Easy Reach.
nRemove the spool from the string head.
NOTE: Keep the spring attached to the spool. Remove any old string remaining on the spool.
nCut two pieces of string, each being approximately 9 ft. (2.7 m) long. Use only .080 in. (2.0 mm) diameter mono- filament string.
nInsert 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.
nRepeat above step with second string, using the bottom part of spool. Do not overfill.
nReplace 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 be- come 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 recommended that only qualified service technicians perform this service.
SPARK ARRESTOR
The spark arrestor must be cleaned or replaced every 25 hours or yearly to ensure proper performance of your product. Spark arrestors may be in different locations depending on the model purchased. Please contact your nearest service dealer for the location of the spark arrestor for your model.
