Be Aware of the Working Environment (all units)
Avoid long-term operation
in very hot or very cold
weather. Make sure bystanders or observers outside the
50-foot “danger zone” wear eye protection.
Be extremely
careful of
slippery terrain,
especially during
rainy weather.
Beware of a coasting blade. A coasting
blade can injure while it continues to
spin after the throttle trigger is released
or after the engine is stopped.
When operating in rocky terrain or near electric
wires or fences, use extreme caution to avoid
contacting such items with the cutting attachment.
Be constantly alert for objects and debris that could be
thrown either from the rotating cutting attachment or
bounced from a hard surface.
If contact is made with
a hard object, stop the
engine and inspect the
cutting attachment for
damage.
Reduce the risk of
bystanders being struck
by flying debris. Make
sure no one is within 50
feet (15 meters)—that’s
about 16 paces—of an
operating attachment.

gasoline and 2-cycle mixing oil only.
Use of non-approved mixing oils can
lead to excessive carbon deposits.
CAUTION!
 Some types of gasoline contain al-
cohol as an oxygenate. Oxygenated
gasoline may cause increased op-
erating temperatures. Under certain
conditions, alcohol-based gasoline
may also reduce the lubricating
qualities of some 2-cycle mixing oils.
 Never use any type of gasoline
containing more than 10% alcohol
by volume! Generic oils and some
outboard oils may not be intended
for use in high-performance 2-cycle
type engines, and should never be
used in your Shindaiwa engine.
 Use only fresh, clean unleaded gasoline
with a pump octane of 87 or higher.
 Mix with 50:1 Shindaiwa Premium
2-cycle mixing oil or with an equivalent
high quality 2-cycle mixing oil.
Examples of 50:1 mixing quantities
 1 gallon of gasoline to 2.6 oz. mixing oil.
 5 liters of gasoline to 100 ml. mixing oil.

WARNING!
Never start the engine from the
operating position.
WARNING!
The cutting attachment may rotate
when the engine is started!
When the Engine Starts...
 After the engine starts, allow the engine
to warm up at idle 2 or 3 minutes before
operating the unit.
 After the engine is warm, pick up
the unit and clip on the harness if so
equipped. See page 17.
 Advancing the throttle makes the cut-
ting attachment turn faster; releasing
the throttle permits the attachment to
stop turning. If the cutting attachment
continues to rotate when the engine
returns to idle, carburetor idle speed
should be adjusted (see page 17).
IMPORTANT!
If the engine fails to start after several at-
tempts with the choke in the closed posi-
tion, the engine may be flooded with fuel.
If flooding is suspected, move the choke
lever to the open position and repeatedly
pull the recoil starter to remove excess
fuel and start the engine. If the engine still
fails to start, refer to the troubleshooting
section of this manual.
6. When the engine starts, slowly move the
choke lever to the "OPEN" position. See
Figure 27. (If the engine stops after the
initial start, close the choke and restart.)
Figure 27
Idle the engine briefly before stopping
(about 2 minutes), then slide the ignition
switch to the “O” (engine OFF) position.

WARNING!
The cutting attachment must NEVER
rotate at engine idle speeds!
NOTE:
Carburetor mixture adjustments are preset
at the factory and cannot be serviced in the
field.
Engine Idle Adjustment
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.
Adjustment Procedure
1. Place the trimmer on the ground, then
start the engine, and then allow it to idle
2-3 minutes until warm.
2. If the cutting attachment rotates at en-
gine idle, reduce idle speed by turning
the idle adjustment screw counter-clock-
wise.
Idle Adjusting
Screw
Initial carburetor mixture adjustments on
non-emission compliance engines are:
Main adjusting screw 2 turns ± 1/4.
Adjustments may vary because of altitudes
and other factors. See your authorized
Shindaiwa dealer for correct adjustments.

WARNING!
The cutting attachment must NEVER
rotate at engine idle! If the engine idle
speed cannot be adjusted by the proce-
dure described here, return the trimmer to
your Shindaiwa dealer for inspection.
3. If a tachometer is available, the engine
idle speed should be final-adjusted to
3,000 RPM (min-1) ±250 RPM (min-1).
WARNING!
A cutting attachment shield or other
protective device is no guarantee of
protection against ricochet. YOU MUST
ALWAYS GUARD AGAINST FLYING
DEBRIS!
Checking Unit Condition
NEVER operate the unit with the cutting
attachment shield or other protective de-
vices (harness, stop switch, blade retention
clip, etc.) removed .
Use only authorized Shindaiwa parts and
accessories with your Shindaiwa trimmer,
brushcutter or lawn edger. Do not make
modifications to the unit without the writ-
ten approval of Shindaiwa, Inc.
ALWAYS make sure the cutting attach-
ment is properly installed and firmly tight-
ened before operation.
NEVER use a cracked or warped cutting at-
tachment: replace it with a serviceable one.
ALWAYS make sure the cutting attach-
ment fits properly into the appropriate
attachment holder. If a properly installed at-
tachment 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 run at high
RPM 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.
NOTE:
Although a shoulder strap accessory is not
required for use with a grass trimmer or a
edger, a shoulder strap can increase opera-
tor comfort during extended periods of
operation. See Figure 30.
Adjust the shoul-
der strap so the
shoulder pad rests
comfortably on the
off-side shoulder
and the cutting
path of the cutting
attachment is par-
allel to the ground.
Make sure all
hooks and adjust-
ment devices are
secure. Figure 30
T260/LE260
WARNING!
Always wear a shoulder strap when op-
erating this unit with a blade. A shoul-
der strap is also recommended when
using trimmer line.
NOTE:
Using a shoulder strap with a brushcutter
allows you to maintain proper control of the
unit and reduces fatigue during extended
operation.

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
horizontal.
Cutting Grass (Units Equipped with a Trimmer Head)
Your Shindaiwa T260 Grass Trimmer may
be equipped with one of several Shindaiwa
trimmer head models, each with features
for specific applications and/or operational
requirements.
NOTE:
A grass trimmer head can also be fitted to the
Shindaiwa C260.
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 man-
ually with the grass trimmer stopped.
CAUTION!
Do not push the rotating line into trees,
wire fences or any material that could
tangle or break line ends.
CAUTION!
Operation at low RPM can lead to pre-
mature clutch failure.
Edging
Tilt the handle about
100° to the left (from
horizontal) and move
forward, holding the
trimmer vertically, as
shown.
Operate the unit at full throttle while cut-
ting grass.
Engine Operating Speeds
 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.

Using a Brushcutter Blade C260/T260X
WARNING!
 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.
 Whenever you strike a hard ob-
ject 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 handle-
bar or barrier bar as well as a har-
ness or strap.
 Always make sure the cutting at-
tachment shield is properly installed
before operating your unit.
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 helps prevent the
operator from moving forward, or the unit
moving rearward, thus preventing inadver-
tent bodily contact with the blade. ALWAYS
KEEP THE HANDLEBAR SECURELY IN
PLACE ON THE UNIT!
Brushcutter Shoulder Strap
A shoulder strap provides additional protec-
tion against blade thrust. In addition, a
shoulder strap gives significant support
and comfort to help ensure safe and ef-
ficient operation.
When operating a T260X or C260 with a
blade, make sure both the handle and har-
ness are adjusted to the size of the operator
using the unit.
Engine Operating Speeds
Operate the unit at full throttle while cut-
ting. Best fuel efficiency is obtained by
releasing the throttle when swinging back
after a cut.
 To prevent possible engine damage, do
not allow the brushcutter to run at high
speeds without a load.
 Avoid operating the engine at low
speeds. Doing so can lead to rapid
clutch wear. In addition, slow-speed op-
eration tends to cause grass and debris
to wrap around the cutting head.
The blade rotates counter-clockwise. For
best performance and to minimize being
stuck by debris, move the blade from right
to left while advancing on your work.
Position the blade so cuts are made be-
tween the blade’s 8 o’clock and 10 o’clock
positions (as viewed from above). DO NOT
cut between the 10 o’clock and 5 o’clock
positions.
WARNING!
When cutting wood with a saw, feed
the blade slowly—never strike or
“slam” a spinning blade against the
wood.
WARNING!
DO NOT use 2-tooth or non-Shindaiwa
approved 4-tooth cutting blades with
Shindaiwa trimmers and brushcutters.
Vertical Cuts
Hold the brushcutter with the blade at
a 90° angle to the ground so the blade’s
bottom edge rotates toward the operator.
Move the blade from top to bottom through
the cut, and cut only with the bottom edge
of the blade.
WARNING!!
When making vertical cuts, never allow
the blade to exceed waist height.
Cut on the left
side of the blade.

Using a Hand-held Edger LE260
CAUTION!
Low-speed edging can lead to prema-
ture clutch failure.
 Before edging, make sure the area is
soft enough so the blade does not bog
down. If necessary, water the area be-
fore edging.
 Remove debris and other obstacles that
could be thrown by the rotating blade.
 Plan your work so the edger blade is
always on your right-hand side.
Begin each pass by positioning the unit
over the work, and with the engine run-
ning at about half-throttle. Slowly lower
the blade to the ground while applying full
throttle.
Guidelines for Operating the Edger.
WARNING!!
 Wear eye protection, long pants, and
boots when operating this unit!
 Whenever you strike a hard object
with the blade, always stop the
edger and carefully inspect the blade
for damage. NEVER OPERATE
THE EDGER WITH A DAMAGED
BLADE!
Figure 36
 Do not move the edger into the work so
fast that the engine or blade bogs down.
Regular and frequent use of the edger
will make a neater lawn, and a frequently
trimmed edge will be easier to maintain.
The edger’s depth of cut is controlled by a
combination of operator height, blade wear,
and the positioning of the edger’s guide
wheel.
To adjust blade height:
1. Loosen the guide wheel adjusting knob.
2. Raise or lower the guide wheel to the
desired setting (see figure 37).
3. Tighten the guide wheel adjusting knob
firmly.
WARNING!!
Never adjust the guide wheel while the
engine is running.
NOTE:
Guide wheel adjustment is also required to
compensate for blade wear.
WARNING!!
Use only Shindaiwa replacement
blades.
