4. The line cutter on the edge of the guard can dull over time. It is recommended you periodically touch-up the sharpness of the blade with a file.

IMPORTANT: To assure product SAFETY and RELIABILITY, repairs, maintenance and adjustment should be performed by authorized service centers or other qualified service organizations, always using identical replacement parts.

Troubleshooting
trimmer runs slowly
•	Unplug the trimmer.
•	Check that the spool housing can rotate freely. Carefully clean it if necessary.
•	Check that the cutting line does not protrude more than approximately 5-3/8 inches (136mm)
	from the spool. If it does, cut it off so that it just reaches the line trimming blade.
Automatic line feed does not work
•	Unplug the trimmer.
•	Remove the spool cap.
•	Pull the cutting line until it protrudes approximately 5-3/8 inches (136mm) from the spool. If
•	insufficient cutting line is left on the spool, install a new spool of cutting line.
	Ensure that the line is not crisscrossed on the spool as detailed in figure Q. If it is, unwind
•	the cutting line, then wind it back on the spool neatly so that the lines do not cross.
	Ensure the beginning of the cutting line is pulled tight against the spool as shown in figure P.
•	Align the tabs on the spool cap with the cut outs in the housing.
•	Push the spool cap onto the housing until it snaps securely into place.
•	If the cutting line protrudes beyond the trimming blade, cut it off so that it just reaches the blade.
	If the automatic line feed still does not work or the spool is jammed, try the following suggestions:
	•	Carefully clean the spool and housing.
	•	Remove the spool and check if the lever in the spool housing can move freely.
	•	Remove the spool and unwind the cutting line, then wind it on neatly again. Replace the
		spool into the housing.
