8-3 Units Equipped with Trimmer Heads

Your Shindaiwa F220/T220/C220
grass trimmer is equipped with a
semiautomatic nylon trimmer head.
Engine Operating Speeds
Operate the unit at full throttle while
cutting grass.
CAUTION!
Do not push the rotating line into trees,
wire fences or any material that could
tangle or break the nylon lines.
CAUTION!
Operation of trimmer without a cutting
attachment shield and using exces-
sive line length can lead to premature
clutch failure.
CAUTION!
Operation at low rpm can lead to
premature clutch failure.
Trimming and Mowing Grass
Hold the grass trimmer as shown in
the illustrations. The trimmer head
should be angled slightly into the area
to be cut. To ensure maximum trim-
mer-line service life, cut only with the
tip of the trimmer line. Sweep the
trimmer head left to right (T220-
C220), and right to left (F220) to trim
the grass. During cutting operations,
the trimmer head should be kept
horizontal to the ground at all times.

9 Blades

WARNING!
n Before working with a blade-
equipped unit, always inspect and
clean the area of objects that could
interfere with or damage the blade.
n Never use a blade near sidewalks,
fence posts, buildings or other
objects that could cause injury or
damage.
n Never use a blade for purposes
other than those for which it was
designed.
n 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!
n A blade-equipped unit must be
equipped with a bicycle-type
handlebar or barrier bar as well as
a harness or shoulder strap.
n Always make sure the cutting
attachment shield is properly
installed before operating
this unit.

9-1 Using a Blade

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!
Brushcutter Handlebar
A brushcutter handlebar or barrier
bar helps prevent the operator from
moving forward, or the unit moving
rearward, thus preventing inadvert-
ent bodily contact with the blade.
ALWAYS KEEP THE HANDLEBAR OR
BARRIER BAR SECURELY IN PLACE
ON THE UNIT!
Brushcutter Shoulder Strap
A shoulder strap provides additional
protection against blade thrust. In
addition, a shoulder strap gives
significant support and comfort to
help ensure safe and efficient opera-
tion.
When operating a unit with a
blade, make sure both the handle
and shoulder strap are adjusted to
the size of the operator using the
unit.
