STRING REPLACEMENT
See Figures 12, 13, 14 and 15.
1. Stop the engine, disconnect the spark plug wire. Hold
the string head and unscrew the spool retainer. Turn
counterclockwise.
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 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 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.
CLEANING THE EXHAUST PORT AND
MUFFLER
Depending on the type of fuel used, the type and amount of
oil used, and/or your operating conditions, the exhaust port
and muffler may become blocked with carbon deposits. If
you notice a power loss with your gas powered tool, a
qualified service technician will need to remove these
deposits to restore performance.
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.
Cleaning Instructions:
■ ■ ■ ■ ■ Remove the spark arrestor from the muffler.

these cleaning instructions:

cleaner.
