OPERATING THE TRIMMER/EDGER
OREGON® Cordless Tool System
TRIMMER/EDGER MODEL ST275
AB 0214 - F/N 564571
CONTROLLING TRIMMER HEAD
SPEED
The throttle trigger controls the speed at
which the trimmer head turns. Squeeze
the throttle trigger more firmly for faster
cutting speed.
Use the lowest pressure required to cut
the material. This helps to maximise
the amount of cutting time per battery
charge and reduces the number of
charging operations required.
ADVANCING TRIMMER LINE
The trimmer line wears down as you use
the trimmer/edger. Let out more trimmer
line as needed.
With the motor running and the trimmer
head turning, bump the trimmer head on
the ground (Fig. ). More trimmer line
comes out of the spool, and excess
trimmer line is cut off by the line cutting
blade on the bottom of the guard.
If the trimmer line does not come out,
the spool may be empty. Turn off the
trimmer/edger and replace trimmer line
as described in “Replacing trimmer line”.
TRIMMING
Trimming cuts grass and weeds that are
close to walls, fences, and other areas too
small to reach with a lawn mower, down
to a manageable height but not down to
soil level.
Assume proper grip and stance, then
start the trimmer. Squeeze the throttle
trigger until the trimmer head achieves
the minimum speed necessary to cut the
grass or weeds.
Angle the trimmer head slightly toward
the direction of the cut (Fig. ).
Push the trimmer head slowly from the
side into the grass or weeds to be cut,
and move the trimmer head back and
forth so that the end of the trimmer line
contacts the material to be cut.
Do not allow the trimmer line to touch
the ground.
