Rules For Safe Operation (With Nylon Line Cutting Head) - Echo SRM-2305 Operator's Manual

The basic cutting actions pictured are:
Trimming, scything, scalping and lawn edging.
These actions are as follows:
TRIMMING: This is feeding the trimmer carefully into the
material you wish to cut. Tilt the head slightly to direct
the debris away from you. If cutting up to a barrier such
as a fence, wall or tree, approach from an angle where
any debris ricocheting off the barrier will fly away from
you. Move the line head or line disc slowly until the
grass is cut right up to the barrier, but do not jam
(overfeed) the line into the barrier. If trimming up to wire
mesh or chain link fencing, be careful to feed only up to
the wire. If you go too far, the line will snap off around
the wire.
Trimming can be done to cut through weed stems one at
a time. Place the nylon line cutter near the bottom of the
weed never high up, which could cause the weed to
chatter and catch the line. Rather than cut the weed
right through, just use the very end of the line to wear
through the stem slowly.
Scalping
SCALPING AND EDGING: Both of these are done with
the line head or line disc tilted at a steep angle. Scalping
is removing top growth, leaving the earth bare. Edging is
trimming the grass back where it has spread over a
pavement or driveway. During both edging and scalping,
hold the unit at a steep angle in a position where the
debris, and any dislodged dirt and stone, will not come
back towards you even if it ricochets off the hard
surface.
Although the pictures show how to edge and scalp,
every operator must find for himself the angles which
suit his body size and cutting situation.

RULES FOR SAFE OPERATION
(WITH NYLON LINE CUTTING HEAD)
Edging
SCYTHING: This is the cutting or mowing of large
grassy areas by sweeping or swinging the trimmer in a
level arc. Use a smooth, easy motion. Do not try to hack
or chop down the grass. Tilt the line head or line disc to
direct the debris away from you on the scything stroke.
Then return without cutting grass for another stroke. If
you are well protected and do not care whether some
debris is thrown in your direction, you may scythe in
both directions.
For nearly all cutting, it is good to tilt the nylon cutter so
that contact is made on the part of line circle where the
line is moving away from you and the shield (See
appropriate picture). This results in the debris being
thrown away from you.
Tilting the head to the wrong side will shoot the debris
toward you. If the nylon line cutter is held flat to the
ground so that cutting occurs on the whole line circle,
debris will be thrown at you, drag will slow the engine,
and you will use up a lot of line.
WARNING
USE ONLY FLEXIBLE, NON-METALLIC LINE
