MAINTENANCE
STRING REPLACEMENT
See Figures 16, 17, 18 and 19.
1. Stop 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.
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 9 ft.
(2.7 m) long. Use only .080 in. (2.0 mm) diameter
monofilament string.
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 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.
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 MUF-
FLER
NOTE: 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, 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 arres-
tor for your model.
