OPERA TING INSTRUCTIONS FOR
USE WITH T RIMMER HEAD
WARNING: Always wear eye protec-
tion. Never lean over the trimmer head. Rocks
or debris can ricochet or be thrown into eyes
and face and cause blindness or other serious
injury.
Beforetrimming,bringenginetoaspeedsuffi-
cient to cut material to be trimmed.
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.
At lower speeds, there is less engine noise and
vibration. The cutting linewill last longer andwill
be less likely to “weld” onto the spool.
Always release the throttle trigger and allow
the engine to return to idle speed when not
cutting.
To stop engine:
S Release the throttle trigger .
S M ove ON/ST OP (I/0) switch to the S T OP (0 )

S The line will easily remove grass and weeds
from around walls, fences, trees and flower
beds, but it also can cut the tender bark of
trees or shrubs and scar fences.
S For trimming or scalping, use less than full
