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.

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 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 muffler is equipped with a spark arrestor (screen inside
the muffler body). Through normal use, the screen can be-
come dirty and should be periodically cleaned or replaced
by an anthorized service dealer.
