Introduction
Read and follow this
operators manual.
Failure to do so could
result in serious injury.
Wear eye and hearing
protection at all times
during the operation
of this unit.
Keep bystanders
at least 50 feet (15 m)

footing and do not
overreach—maintain
your balance at
all times during
operation.
Wear appropriate footwear (non-skid
boots or shoes): do not wear opentoed shoes or sandals. Never work
barefooted!
Wear hearing protection devices
and a broad-brimmed hat or helmet.
Always wear eye protection such as
goggles or safety glasses.
Always wear a shoulder strap or
a harness when operating a unit
equipped with a blade.
Always operate with both hands
rmly gripping the unit.
When operating with a blade, make sure
the handle is positioned to provide you with
maximum protection from contacting the blade.
Keep away from the rotating trimming
line or blade at all times, and never lift a
moving attachment above waist-high.
Figure 2
Be Aware of the Working Environment
Avoid long-term
operation in very hot or
very cold weather.
Be extremely careful of slippery
terrain, especially during rainy
weather.
If contact is made with a hard
object, stop the engine and
inspect the cutting attachment for
damage.
Be constantly alert for objects and debris
that could be thrown either from the rotating
cutting attachment or bounced from a hard
surface.

WARNING!
A standard grass trimmer with a
loop handle should NEVER be operated
with blade-type attachments. For blade
use the trimmer must be tted with a
bicycle-type handlebar or a loop handle
with a barrier bar that is located in front
of the operator to reduce the risk of
the operator coming in contact with the
cutting attachment (per ANSI B175.3).
When using a blade, the unit must also
be equipped with a harness or strap.

Mixing fuel
CAUTION!
Never use any type of gasoline
■
containing more than 10% alcohol
by volume! Some types of gasoline contain alcohol as an oxygenate. Oxygenated gasoline may
cause increased operating temperatures. Under certain conditions,
alcohol-based gasoline may also
reduce the lubricating qualities of
some 2-cycle mixing oils.
Generic oils and some outboard

oils may not be intended for use
in high-performance two-cycle engines, and should never be used
in your Shindaiwa engine.
Filling the fuel tank
WARNING!
minimize the Risk of Fire
NEVER smoke or light res near the
engine.
ALWAYS stop the engine and allow it
to cool before refueling.
ALWAYS Wipe all spilled fuel and move
at least 3 meters from the fueling point
and source before starting.
CAUTION!
This engine is designed to operate on
a 50:1 mixture consisting of unleaded
gasoline and ISO-L-EGD or JASO FC
class 2-cycle mixing oil only. Use of
non-approved mixing oils can lead to
excessive carbon deposits.
Use only fresh, clean unleaded gasoline

requirements.
leaks are evident, stop using the
unit immediately. Fuel leaks must be
repaired before using the unit.
ALWAYS move the unit at least 3
meters away from a fuel storage area
or other readily ammable materials
before starting the engine.
NEVER place ammable material close
to the engine mufer.

Starting the Engine
IMPORTANT!
Engine ignition is controlled by a two-position on-off switch mounted on the throttle body. This switch is typically labeled “I” for
ON and “O” for OFF.
WARNING!
Never start the engine from
the operating position.
Slide the ignition switch to the “ON”

Engine Idle Adjustment
Idle the engine briefly before stopping
(about 2 minutes), then slide the ignition
switch to the “O” (OFF) position. See
Figure 20.
The engine must return to idle speed
whenever the throttle lever is released.
Idle speed is adjustable, and must be set
low enough to permit the engine clutch
to disengage the cutting attachment
when the throttle is released.
Idle Speed Adjustment
WARNING!
The cutting attachment must
NEVER rotate at engine idle! If the
idle speed cannot be adjusted by the
proceedure described here, have
the unit inspected at an authorized
Shindaiwa dealer.
Place the unit on the ground, then
1.
start the engine and allow it to idle for
2-3 minutes until warm.
Checking Unit Condition
NEVER operate the unit with the cutting
attachment 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.
WARNING!
A cutting attachment shield
or other protective device is no
guarantee of protection against
thrown objects. YOU MUST ALWAYS
GUARD AGAINST FLYING DEBRIS!
Idle Adjusting
Screw
Figure 21
If the attachment rotates when the
2.
engine is at idle, reduce the idle speed
by turning the idle adjustment screw
counter-clockwise. See Figure 21.
ALWAYS make sure the cutting attachment is properly installed and firmly
tightened before operation.
NEVER use a cracked or warped cutting
attachment: replace it with a serviceable one.
ALWAYS make sure the cutting attachment fits properly into the appropriate
cutter holder. If a properly installed
attachment 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 equipment.
If a tachometer is available, the
3.
engine idle speed should be final
adjusted to 3,000 (±250) min
-1
(rpm).
NOTE:
Carburetor fuel mixture adjustments are
preset at factory on units with emission
control systems and cannot be serviced
in the eld.
NEVER allow the engine to operate at
high RPM’s without a load. Doing so
could damage the engine.
NEVER operate a unit with worn or damaged fasteners or attachment holders.
NEVER cut with dull blades. Doing so
will increase the risk of blade thrust and
may also damage your equipment.

Operation
Shoulder Strap T272X
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
adjustment devices are secure.
Cutting grass 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.
Trimmer head styles:
Semi-automatic. Trimmer line is indexed
when the operator taps the trimmer head
on the ground during operation.
manual. The operator indexes line manually with the grass trimmer stopped.
Fixed. The operator must stop the
unit and add new lengths of trimmer
line manually.

three nylon blades attached to the
head by pivots.
Shoulder Strap
recommended
for use with grass
trimmers
Figure 22
NOTE:
Additional hardware may be required to
mount the Fixed Line or the Flail type
trimmer heads.
Engine Operating Speeds
Operate at full throttle while cutting grass.
CAUTION!
Operation at low rpm can lead to
premature clutch failure.
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
trimmer line. Cut grass by swinging the
unit's trimmer head from left to right.
Keep the trimmer head horizontal.
CAUTION!
Do not push the rotating line into
trees, wire fences or any material that
could tangle or break line ends.
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.
