Line Feeding
Your trimmer uses .065 in. (1.65mm) diameter nylon line to
cut grass and weeds quickly and easily. In time, the tip of the
nylon line will become worn and the auto feed mechanism will
automatically feed and trim a fresh length of line.
The cutting line will wear faster if the cutting is done along sidewalks or other abrasive
surfaces or if heavier weeds are being cut. The automatic feed mechanism senses when
more cutting line is needed and feeds and trims the correct length of line whenever it
is required. No action is required to advance the line. Do not bump unit on ground in
attempt to feed line or for any other purpose.
Replacing Spool/Clearing Jams and Tangled Lines
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.
• Turn off the trimmer and remove the battery.
• Press the release tabs on the line spool cover, as shown in
figure 15 and remove the cover by pulling it straight off.
• Lift the spool of nylon line out of the hub and clear any broken
line or cutting debris from the spool area.
