MAINTENANCE
■ Push down and turn the spool counterclockwise until
it no longer turns. Hold the spool down and rotate
clockwise a small amount. Release the spool. The
spool should be locked down in the string head. If not,
hold down and rotate until locked.
■ Make sure the string head and the spool retainer are
installed on the shaft connector by turning the retainer
counterclockwise to tighten.
■ Pull the strings again to rotate the spool into cutting
position. Push the spool retainer down while pulling
on string(s) to manually advance the string and to
check for proper assembly of the string head.
STRING REPLACEMENT (Fig. 20 - 23)
■ Stop the engine and disconnect the sparking plug
wire. Hold the string head and unscrew the spool
retainer. Turn clockwise.
■ Remove the spool from the string head.
NOTE: Keep the spring attached to the spool.
Remove any old string remaining on the spool.
■ Cut two pieces of string, each being approximately
2.7 m long.
■ 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 extended beyond
the slot. Do not overfill. After winding the string, there
should be at least 6 mm between the wound string
and the outside edge of the spool.
■ Repeat above step with second string, 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 on the blade when the
unit is not in use. The blade protector has clips round 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 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 performance.
SPARK ARRESTER
The spark arrester must be cleaned or replaced every
25 hours or yearly to ensure proper performance of

depending on the model purchased. Please contact your
nearest service dealer for the location of the spark
arrester for your model.
