GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal
injury.
Periodically, clean all foreign material from the trimmer head
vents.
You can often make repairs described here. For other repairs,
have the trimmer serviced by an authorized service dealer.
SPOOL REPLACEMENT
See Figure 1.

 Push in tabs on side of spool retainer.
 Pull spool retainer up to remove.
 Remove 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 end of each string is extended
approximately 6 in. beyond each slot.
 Install the new spool so that the strings and slots align
with the eyelets in the string head. Thread the strings into
the eyelets.
 Pull the strings extending from the string head so the
string releases from the slots in the spool.
 Reinstall the spool retainer by depressing tabs into slots
and pushing down until spool retainer clicks into place.

ft. (2.7 m) long. Use only .065 in. (1.65 mm) diameter
monofilament string.
 Insert the first string into the anchor hole 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. Place string in the slot on upper spool flange,
leaving about 6 in. (152 mm) extended beyond the slot.
