ensure debris is thrown away from you.
Without bending over, keep line near and
parallelto the ground and not c rowded into
material being cut.
Do not run the engine at a higher speed than
necessary. The cutting line will cut efficiently
when the engine is run at less than full throttle.
Atlo wer speeds, there is less eng ine noise and
vibration. The cutting line will last longer and will
be less likely to “weld” onto the spool. Al ways
release the throttle trigger and allow the en-
gine to return to idle speed when not cutting.

SRelease the throttle trigger.
SPush and release the engine ON/STOP
switch.

anddo not cr owd the line when cutting around
hardobjec ts (rock, gravel, fence posts, etc.) ,
whichcan damage the tr immer head, become
entangled in the line, or be thrown causing a
serious hazard.
SThetip of the line does the c utting. Youwill
achieve the best performance and mini-
mumline wear by not c rowding the line into
thecut ting area. The right and wrong ways
are shown below.
