AUTOMATIC LINE FEED SYSTEM

 (fig 11)

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 same amount trimmer line. 

If the noise of the line being cut can’t be heard, 
more line will be fed out. To feed more line, it is first 
necessary to allow the trimmer to stop completely, 
and then restart, allowing the motor to reach full 
speed. Repeat above until you hear the lines hitting 
against the line cutter.

A “clattering” noise will be heard when the lines hit the line cutter. Do not be alarmed; this is quite 
normal. After several seconds the line will be cut to the correct length and the noise will reduce as the 
motor reaches full speed.

NOTICE:

 Remove the protective film on the line cutter before operating the tool.
