MAINTENANCE
Insert the first string (55) into the anchor hole (56)
■
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 (57). 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.
Repeat above step with second string (58), using the
■
bottom part of spool. Do not overfill.
Replace the spool and the spool retainer. Refer to
■
"Spool Replacement " earlier in this manual.
BLADE PROTECTOR (Fig. 24)
Always place the blade protector (59) on the blade (6)
when the unit is not in use. The blade protector has
clips (60) around the edges to snap over the blade and
keep it in place. Wear gloves and be cautious when
handling the blade.
Note: Always remove the blade protector before using
the unit. If not removed, the blade protector could
become a thrown object as the blade begins to turn.
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.

A leaking fuel cap is a fire hazard and must be
replaced immediately.
The fuel cap contains a non-serviceable filter and a
check valve. A clogged fuel filter will cause poor engine
performance. If performance improves when the fuel cap
is loosened, check valve may be faulty or filter clogged.
Replace fuel cap if required.
