STRING REPLACEMENT
See Figures 12, 13, 14 and 15.
1 Stop the engine and disconnect the sparking plug
wire. Hold the string head and unscrew the spool
retainer. Turn anticlockwise.
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 round
the upper part of the spool anticlockwise, 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
SILENCER
Depending on the type of fuel used, the type and
amount of oil used, and/or your operating conditions,
the exhaust port and silencer may become blocked
with carbon deposits. If you notice a power loss with
your petrol-powered tool, a qualified service technician
will need to remove these deposits to restore perfor-
mance.

The spark arrester must be cleaned or replaced every
25 hours or yearly to ensure proper performance of your
product. Spark arresters may be in different locations
depending on the model purchased. Please contact
your nearest service dealer for the location of the spark
arrester for your model.
