Thank you for sharing your review with us. We appreciate all reviews as it helps us improve! When initially switching on the trimmer, a small length of line is fed out. Each time the tool is started from rest it will advance about 0.25 inches of trimmer line. A ‘clattering’ noise will be heard when the lines hit the Line Cutter. Please don't be alarmed, this is quite normal. After about 5 seconds the line will be cut to the correct length and the noise will reduce as the motor gains full speed. If the noise of the line being cut can’t be heard, more line will need to be fed out. To feed more line, it is first necessary to allow the trimmer to stop completely; it must come to a complete rest, then restart, allowing the motor to reach full speed. Repeat above until you hear the line hitting against the Line Cutter.

If required, line can be fed out manually. To operate, press and release manual Line Feed Button (refer to the trimmer diagram in the owner’s manual), while gently pulling out the line until it is long enough to reach the Line Cutter. If the line extends past the Line Cutter, too much line has been fed out. If too much line is fed out, remove the Spool Cap and turn Spool counterclockwise until the line is at the desired length.

Also, ensure you are using a fresh pack of spools. The spool line is biodegradable. This means that the line will decay over time. Elements such as heat, sunlight exposer, and moisture specifically will cause this process to happen more quickly. To have your spools last and perform as they should longer, please store the spools in a cool and dry location. Room temperature is good.
