string head and unscrew the spool retainer.
To remove the spool retainer:
Turn the spool retainer counterclockwise for Trimlite and
Trim n’ Edge.

n Remove the spool from the string head.
NOTE: Keep the spring attached to the spool. Remove
any old string remaining on the spool.
n
Cut two pieces of string, each being approximately 9 ft.
(2.7 m) long. Use only .080 in. (2.0 mm) diameter mono-
filament string.
n 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.
n Repeat above step with second string, using the bottom
part of spool. Do not overfill.
n 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 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.
