Cutting Cords
WARNING! Always turn the engine off when installing or changing cutting cords.
Note: Before trimming, engage the cutting head with the engine running and spin new cords for
a few seconds so they pull tight and set.
Figures 22 and 23 illustrate how the cords are installed on the line plates. There are two sets of
installation points on each line plate, 180 degrees apart. One set of holes is for larger cord (155
mil) and is marked with large arrows. The other set of holes accommodates smaller cord (130
mil) and is marked with small arrows. Always install two cords opposite each other for the best
performance.
Caution! Running the trimmer with only one cord installed, or cords installed at other than 180
degrees can cause excessive vibration and may damage the machine.
