Using A Blade - Shindaiwa C242 Owner's/Operator's Manual

Engine Operating Speeds
Operate at full throttle while cutting
grass.
CAUTION!
Operation at low rpm can lead to
premature clutch failure.
NOTE:
Additional hardware may be required to
mount the Fixed Line or the Flail type
trimmer heads.
Trimming and Mowing Grass
Hold the grass trimmer so the trimmer
head is angled slightly into the area to be
cut. To ensure maximum trimmer-line
service life, cut only with the tip of the trim-
mer line. Cut grass by swinging the unit's
trimmer head from left to right. Keep the
trimmer head horizontal.
WARNING!
Operation of this equipment
may create sparks that can start
fires. This unit is equipped with a
spark arrestor to prevent discharge
of hot particles from the engine.
Metal blade use also can create
sparks if the blade strikes rocks,
metal, or other hard objects. Con-
tact local fire authorities for laws or
regulations regarding fire preven-
tion requirements.

Before working with a blade-
equipped unit, always inspect and
clean the area of objects that could

other than those for which it was
designed.

CAUTION!
Do not push the rotating line into
trees, wire fences or any material
that could tangle or break line ends.
CAUTION!
Use only flexible, nonmetallic line
recommended by the manufacturer.
Never use, for example, wire or
wire-rope, which can break off and
become a dangerous projectile.
■
Whenever you strike a hard object
with a blade, always stop the
brushcutter and carefully inspect
the blade for damage. NEVER
OPERATE THE BRUSHCUTTER
WITH A DAMAGED BLADE!
■
A blade-equipped unit must be
equipped with a bicycle-type han-
dlebar or barrier bar as well as a
harness or shoulder strap.
■
Always make sure the cutting
attachment shield is properly
installed before operating this unit.
CAUTION!
■
Operation of trimmer without a cut-
ting attachment shield and using
excessive line length can lead to
premature clutch failure.
■
Operation at low rpm can lead to
premature clutch failure.
Blade Thrust
"Blade thrust" is a sudden sideways or
backward motion of the brushcutter. Such
motion may occur when the blade jams
or catches on an object such as a sapling
tree or tree stump. BE CONSTANTLY
ALERT FOR BLADE THRUST AND
GUARD AGAINST ITS EFFECTS!
WARNING!
Blade thrust can occur with-
out warning if the blade snags,
stalls or binds.
WARNING!
Blade thrust is more likely to
occur in areas where it is difficult to
see the material being cut.
