Ducati DBC 3300M Owner's Manual page 39

The proper debris shield must be in place
on the unit when nylon cutting line is used.
The cutting line can flap around if too much
line is exposed. Always use the plastic
debris shield with cut-off knife when using
nylon cutting heads.
Tilting the head to the wrong side will shoot the
debris TOWARDS you.If the line head 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 down, and you
will use up a lot of lines.
Use only quality nylon monofilament line of the
diameter 2.5mm. Never use wire or wire-rein-
forced line in place of nylon trimmer line. Load
your nylon line cutting head only with nylon
trimmer line of the proper diameter.
Use extreme caution when operating over bare
spots and gravel, because the line can throw
small rock particles at high speeds. Debris
shields on the unit cannot stop objects which
bounce or ricochet off hard surfaces.
For nearly all cutting, it is good to tilt the line
head so that contact is made on the part of the
line circle where the line is moving away from
you and the debris shield. (See appropraite
picture) This results in the debris being thrown
away from you.
Trimming
This is feeding the trimmer carefully into the
material you wish to cut. Tilt the head slowly to
direct debris away from you. It' cutting up to a
barrier such as fence, wall or tree. approach from
an angle where anydebris ricocheting off the
barrier will fly away from you. Move the line head
slowly until the grass is cut right up the barrier,
but do not jam(overfeed )the line into the barrier.
If trimming up to a wire mesh or chain linked
fence be careful to feed only up to wire. If you
go to far the line will snap off around the wire.
Trimming can be done to cut through weed
stems one at a time. Place the trimmer line head
near the bottom of the weed-never high up which
could cause the weed to chatter and catch the
line.
Owner's manual
Rather than cut the weed right through, just use
the very end of the line to wear through the stem
slowly.
Do not use a steel blade for edging or scalping.
Scalping and edging:
Both of these are done with the line head tilted
at a steep angle scalping is removing top growth
leaving the earth bear.
Edging is trimming the grass back where it has
spread over a sidewalk or drive way.
During both edging and scalping, hold the unit a
steep angle and in a position where the debris,
and any dislodging dirt and stones, will not come
back towards you even if it ricochets off the hard
surface. Although the picture shows how to edge
and scalp every oprator must find for himself
the angles which suits his body size and cutting
situation.
