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 ser-
vice life, cut only with the tip of the trimmer
line. Cut grass by
swinging the unit’s
trimmer head from
left to right. Keep the
trimmer head hori-
zontal. See Figure 23.
Edging
Tilt the handle about 100°
to the right (from horizon-
tal) and move forward,
holding the trimmer verti-
cal as shown in
Figure 24.
Check Unit Condition
NEVER operate the unit with the cutting at-
tachment shield or other protective devices
(harness, ignition switch, blade retention
clip, etc.) removed!
Use only authorized Shindaiwa parts and
accessories with your Shindaiwa trimmer
or brushcutter. Do not make modifications
to the unit without the written approval of
Shindaiwa, Inc.
Shoulder Strap T272X
Shoulder Strap
recommended for
use with grass
trimmers
WARNING!
Always wear a shoulder strap when
operating this unit with a blade. A
shoulder strap is also recommended
when using trimmer line.
IMPORTANT!
Adjust the shoulder strap or harness so
the shoulder pad rests comfortably on the
off-side shoulder and the cutting path of
the cutting attachment is parallel to the
ground. Make sure all hooks and adjust-
ment devices are secure.
Using a T272X with a Blade
Figure 22
ALWAYS make sure the cutting attach-
ment is properly installed and firmly tight-
ened before operation.
NEVER use a cracked or warped cutting
attachment: replace it with a serviceable
one.
ALWAYS make sure the cutting attach-
ment fits properly into the appropriate
cutter holder. If a properly installed attach-
ment vibrates, replace the attachment with
a new one and re-check.
ALWAYS stop the engine immediately and
check for damage if you strike a foreign
object or if the unit becomes tangled. Do
not operate with broken or damaged equip-
ment.
NEVER allow the engine to operate at high
RPM’s without a load. Doing so could dam-
age the engine.
NEVER operate a unit with worn or dam-
aged fasteners or attachment holders.
NEVER cut with dull blades. Doing so will
increase the risk of blade thrust and may
also damage your equipment.
Cutting Grass—Units Equipped with a Trimmer Head
Your Shindaiwa T272 or T272X Grass Trim-
mer 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:
 Semi-automatic. Trimmer line is
indexed when the operator taps the trim-
mer head on the ground during opera-
tion.
 Manual. The operator indexes line
manually while the grass trimmer
is stopped.
 Fixed. The operator must stop the
unit and add new lengths of trimmer line
manually.
 Flail. This device, designed for clearing
weeds and light brush, features three
nylon blades attached to the head by
pivots.
Engine Operating Speeds
Operate the unit at full throttle while
cutting grass.
WARNING!
Operation at low RPM (min -1 ) can lead
to premature clutch failure.

NOTE:
Although a shoulder strap accessory is not
required for use with a grass trimmer, a
shoulder strap can increase operator comfort
during extended periods of operation.
T272
NOTE:
Using a shoulder strap when operating this
unit with a blade allows you to maintain
proper control of the unit and reduces fatigue
during extended operation.
WARNING!
A cutting attachment shield or other
protective device is no guarantee of
protection against thrown objects. YOU
MUST ALWAYS GUARD AGAINST
FLYING DEBRIS!
CAUTION!
Operation of trimmer without a line
cutter and using excessive line length
can lead to premature clutch failure.
NOTE:
Additional hardware may be required to
mount the Fixed Line or the Flail type
trimmer heads.
CAUTION!
Do not push the rotating line into trees,
wire fences or any material that could
tangle or break line ends.
