WARNING:
When servicing, use only identical replacement parts.
Use of any other parts can create a hazard or cause
product damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1. Failure to do so could result in
objects being thrown into your eyes, resulting in possible
serious injury.
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

Before each use, inspect the entire product for damaged,
missing, or loose parts such as screws, nuts, bolts, caps, etc.
Tighten securely all fasteners and caps and do not operate
this product until all missing or damaged parts are replaced.
Please call 1-800-242-4672 or contact an authorized service
center for assistance.
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 can result in serious personal injury.
You can often make repairs described here. For other repairs,
have the trimmer serviced by an authorized service dealer.
Periodically, clean all foreign material from the trimmer head
air vents.

MAINTENANCE

SPOOL REPLACEMENT
See Figure 14.
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.
 Install the new spool so that the lines and slots align with
the eyelets in the string head. Thread the lines into the
eyelets.
 Pull the lines extending from the string head 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 Figures 14 - 15.
 Unplug the string trimmer.
 Remove the spool from the string head.
NOTE: Remove any old line remaining on the spool.
 Cut two pieces of line, each being approximately
9 ft. (2.7 m) long. Use only .065 in. (1.65 mm) 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 counterclockwise, as shown by the arrows on
the spool. Place line in the slot on upper spool flange,
leaving about 6 in. (152 mm) extended beyond the slot.
Do not overfill. After winding the line, there should be
at least 1/4 in. (6 mm) 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 spool retainer, spool, and the spool retainer.
Refer to Spool Replacement earlier in this manual.
STORING THE TRIMMER
 Depress telescoping shaft coupler and set at shortest
setting.
 Clean all foreign material from the trimmer.
 Store it in a place that is inaccessible to children.
 Keep away from corrosive agents such as garden
chemicals and de-icing salts.
