WARNING:
Before inspecting, cleaning, or servicing the machine,
shut off motor, wait for all moving parts to stop, and
disconnect extension cord. Failure to follow these
instructions can result in serious personal injury or property
damage.
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
air vents.
You can often make repairs described here. For other repairs,
have the trimmer serviced by an authorized service center.
SPOOL REPLACEMENT
See Figure 15.
Use only .065 in. diameter monofilament line. Use original
manufacturer’s replacement line for best performance.

Unplug the string trimmer.
 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 lines are captured
in the slots opposite each other on the new spool. Make sure
the end of each line is extended approximately 6 in. beyond
each slot.
MAINTENANCE
 Install the new spool so that the lines and slots align with the
eyelets in the line head. Thread the lines into the eyelets.
 Pull the lines extending from the line head so the line 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.
LINE REPLACEMENT
See Figure 16.

Unplug the line trimmer.
 Remove the spool from the line head.
NOTE: Remove any old line remaining on the spool.

Cut two pieces of line, each being approximately
9 ft. long. Use only .065 in. diameter monofilament line.
 Insert the first line into the anchor hole in the upper part of
the spool. Wind the first line around the upper part of the
spool clockwise, as shown by the arrows on the spool. Place
line in the slot on spool, leaving about 6 in. extended beyond
the slot. Do not overfill. After winding the line, there should
be at least 1/4 in. between the wound line and the outside
edge of the spool.
 Repeat above step with second line, using the bottom part
of spool. Do not overfill.
 Replace the plastic retainer, spool, and the spool retainer.
Refer to Spool Replacement earlier in this manual.
STORING THE TRIMMER

 Depress telescoping boom coupler and set at shortest set-
ting.

 Store it in a place that is inaccessible to children.
 Keep away from corrosive agents such as garden
chemicals and de-icing salts.
