4. Thread the strings into the eyelets (30) in the string
head. Carefully push the spool into the string head
(gently pull the strings to the outside if necessary).
When the spool is positioned in the string head,
grasp the strings and pull sharply to release them from
the slots in the spool.
5. Push down and turn the spool anticlockwise 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.
6. Make sure the string head and the spool retainer are
installed on the shaft by turning the retainer anti-
clockwise to tighten.
7. 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. 12, 13, 14 & 15)
1. Stop the engine and disconnect the sparking plug wire.
Hold the string head and unscrew the spool retainer.
Turn clockwise.
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 (34) into the anchor hole (33) 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 (35) 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 (36), 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 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 petrol-
powered tool, a qualified service technician will need to
remove these deposits to restore performance.
