Cutting Grass—Units equipped with a trimmer head
Your Shindaiwa unit may be equipped
with one of several Shindaiwa trimmer
head models, each with features for
specific applications and/or operational
requirements.
NOTE:
For proper operation, always refer to
the instructions accompanying the
trimmer head being used. Available
trimmer head styles include:
n Semi-automatic. Trimmer line is
indexed when the operator taps the
trimmer head on the ground during
operation.
n Manual. The operator indexes line
manually with the grass trimmer
stopped.
n Fixed. The operator must stop the
unit and add new lengths of trimmer
line manually.
n Flail. This device, designed for
clearing weeds and light brush, fea-
tures three nylon blades attached to
the head by pivots.
NOTE:
Additional hardware may be required
to mount the Fixed Line or the Flail
type trimmer heads.
Using a Blade
■
Before working with a blade-equipped unit, always
inspect and clean the area of objects that could
interfere with or damage the blade.
■
Never use a blade near sidewalks, fence posts,
buildings or other objects that could cause injury or
damage.
■
Never use a blade for purposes other than those
for which it was designed.
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 without 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.

CAUTION!
Do not push the rotating line into
trees, wire fences or any material
that could tangle or break line ends.
Engine Operating Speeds
Operate the unit at full throttle while cut-
ting grass.
CAUTION!
Operation of trimmer without a cut-
ting attachment shield and using
excessive line length can lead to
premature clutch failure.
CAUTION!
Operation at low RPM can lead to
premature clutch failure.
WARNING!
■
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 DAM-
AGED BLADE!
■
A blade-equipped unit must be equipped with a bicycle-
type handlebar or barrier bar as well as a harness or
shoulder strap.
■
Always make sure the cutting attachment shield is prop-
erly installed before operating this unit.
Hold the 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
trimmer line. Cut grass by swinging
the trimmer from left to right. Keep the
trimmer head horizontal.
