MAINTENANCE
You may make adjustments and repairs described
■
here. For other repairs, have the trimmer serviced by
an authorized service agent.
Consequences of improper maintenance may include
■
excess carbon deposits resulting in loss of
performance and discharge of black oily residue
dripping from the muffler.
Make sure all guards, straps, deflectors and handles
■
are properly and securely attached to avoid the risk of
personal injury.
SPOOL REPLACEMENT
EZ LINE™ TAP ADVANCE SYSTEM
NEW PRE-WOUND SPOOL (Fig. 16-17)
If replacing string only, refer to "String Replacement" later
in this manual.
Use only 2.4 mm diameter monofilament string.
Use the manufacturer's replacement string for best
performance.
Stop the engine and disconnect the sparking plug
■
wire. Hold the string head (36) and unscrew the spool
retainer (37). Turn clockwise.
Remove the empty spool (50) from the string head.
■
Keep the spring (54) attached to the spool.
To install the new spool, make sure the two strings are
■
captured in the slots opposite each other on the new
spool. Make sure the ends of each string are extended
approximately 152 mm beyond each slot (53).
Thread the strings into the eyelets (51) 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.
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.
Make sure the string head and the spool retainer are
■
installed on the shaft (52) by turning the retainer anti-
clockwise 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. 18-21)
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 (55) into the anchor hole (56) 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 (57). 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 (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. 22)
Always place the blade protector (59) on the blade when the
unit is not in use. The blade protector has clips (60) 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.
