Use Only 0.065" (1.65 mm) Diameter,
Round Line
Bulk line is also available for purchase from your localretailer.
NOTE: Hand wound spools from bulk line are likely to

factory wound spools. For best results, factory wound spools
arerecommended.

anchoring slots
27
.
5. Insert the 3/4" (19 mm) end of the bulk line into the
spool hole
30
in the spool adjacent to the slot. Make
sure the line is pulled tight against thespool.
USE ONLY .065" (1.65 mm) DIAMETER ROUND NYLON
MONOFILAMENT LINE. Do not use serrated or heavier gauge
line, as they will overload the motor and cause overheating.
This line is available at your local dealer or authorized
servicecenter.

27
in the spoolhousing.

Clearing Jams and Tangled Line (Fig.R)

WARNING: Remove the battery from the
trimmer before making any assembly, adjustments or
changing accessories. Such preventive safety measures
reduce the risk of starting the applianceaccidentally.
From time to time, especially when cutting thick or stalky
weeds, the line feeding hub may become clogged with
sap or other material and the line will become jammed as a
result. To clear the jam, follow the steps listedbelow.

CAUTION: To avoid appliance damage, if
the cutting line protrudes beyond the trimming blade,
cut it off so that it just reaches theblade.
1. Remove battery fromappliance.
2. Press the release tabs
20
on the spool cap
19
, and
remove the spool cap from the spool housing
11
.
3. Pull the nylon line spool out and clear any broken line or
cutting debris from the spool area.
4. Fit the spool onto the appliance as described in
Replacing SpoolAssembly.
Cutting Line / Line Feeding
Your trimmer uses 0.065" (1.65 mm) diameter, round nylon
line. During use, the tips of the nylon lines will become
frayed and worn. Cutting line will wear faster and require
more feeding if the cutting or edging is done along sidewalks
or other abrasive surfaces or heavier weeds are beingcut.
• Wire and picket fences cause extra string wear, even
breakage. Stone and brick walls, curbs, and wood may
wear stringrapidly.
• Do not allow spool cap
19
to drag on ground or
othersurfaces.
• In long growth, cut from the top down and do not
exceed 13" (330 mm)high.
• Keep trimmer tilted toward the area being cut; this is the
best cuttingarea.
• The trimmer cuts when passing the unit from the left to
right. This will avoid throwing debris at theoperator.
• Avoid trees and shrubs. Tree bark, wood moldings, siding,
and fence posts can easily be damaged by thestring.
