Filling the Fuel Tank
IMPORTANT!
Mix only enough fuel for your immediate
needs! If fuel must be stored longer than
30 days and oil with fuel stabilizer
is not used, it should first be treated with a
fuel stabilizer such as STA-BIL™.
Mixing Fuel
CAUTION!
This engine is designed to operate on
a 50:1 mixture consisting of unleaded
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!
Minimize the Risk of Fire!
 STOP engine before refueling.
 ALWAYS allow the engine to cool
before refueling!
 Wipe all spilled fuel and move the
engine at least 10 feet (3 meters)
from the fueling point and source
before restarting!
 NEVER start or operate this
unit if there is a fuel leak.
1. Place the unit on a flat, level surface.
2. Clear any dirt or other debris from
around the fuel filler cap.
3. Remove the fuel cap, and fill the tank
with clean, fresh fuel.

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.
 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 10).
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 18. (If the engine stops after the
initial start, close the choke and restart.)
Figure 18
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 when-
ever the throttle lever is released. Idle speed
is adjustable, and must be set low enough to
permit the engine clutch to disengage the cut-
ting 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.
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 edger to
your Shindaiwa dealer for inspection.
2. If the cutting attachment rotates at engine
idle, reduce idle speed by turning the idle
adjustment screw counter-clockwise.
3. If a tachometer is available, the engine
idle speed should be final-adjusted to
2,750 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 ac-
cessories with your Shindaiwa lawn edger.
Do not make modifications to the unit with-
out the written 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.
Using a Hand-held Edger
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 21
 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.

11
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 22).
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.

 Use a hooked wire to extract the fuel filter
from inside the fuel tank. See figure 26.
Lubricate the Flexible Shaft.
Lack of lubrication will cause rapid wear to
the flexible shaft and also to the shaft tube
liner, resulting in increased vibration and
greatly decreased service life. Remove and
lubricate the flexible shaft as follows:
1. Loosen the gearcase clamp screw.
2. Remove the gearcase index screw.
3. Slide the gearcase and shield assembly
from the shaft tube.
4. Pull the flexible shaft from the shaft tube
assembly, and clean the shaft thorough-
ly in solvent.
5. Inspect the shaft carefully, and discard if
worn or damaged.

Remove and replace the filter element.
Before reinstalling the new filter ele-
ment, inspect the condition of all the
fuel system components (fuel pick-up
line, fuel return line, tank vent line, tank
vent, fuel cap and fuel tank). If damage,
splitting or deterioration is noted, the
unit should be removed from service
until it can be inspected or repaired by a
Shindaiwa-trained service technician.
6. Coat the entire length of the shaft with
Shindaiwa Premium Gearcase Lube (or
equivalent), and reinstall the shaft in the
shaft tube assembly.
NOTE:
For extended shaft life, the flexible cable
should be reversed end-for-end during the
reinstallation process.
Inspect the Gearcase Protector
The metal gearcase protector (p/n 72958-
16210) is installed to protect the gearcase
flange from damage when working close to
sidewalks or other abrasive surfaces, and
should be routinely inspected for damage
or excessive wear.
When replacing the protector, inspect to be
sure that both of the protector mounting
screws are firmly tightened and each screw
is locked in place with a nut as shown.
CAUTION!
The D-shaped shim washer must be
positioned with its flat edge toward the
shaft tube.

Muffler
Hard starting or a gradual loss of perfor-
mance can be caused by carbon deposits
lodged in the muffler’s spark arrester
screen.
In such cases, performance can usually be
restored by removing the arrester screen
and giving it a thorough cleaning with a
stiff bristle brush.
If carbon deposits are severe or if no per-
formance improvement is noted, your 260
unit should be returned to your Shindaiwa
dealer for inspection.

WARNING!
Never operate this unit with a damaged
or missing muffler or spark arrester!
Operating with missing or damaged
exhaust components is a fire hazard,
and could also damage your hearing.

Long Term Storage
Whenever the unit will not be used for 30
days or longer, use the following proce-
dures to prepare it for storage:
 Clean external parts thoroughly and
apply a light coating of oil to all metal
surfaces.
 Drain all the fuel from the fuel tank.
IMPORTANT!
All stored fuels should be stabilized with
a fuel stabilizer such as STA-BIL™, if
oil with fuel stabilizer is not used.
 Remove the spark plug and pour about
1/4 ounce of 2-cycle mixing oil into the
cylinder through the spark plug hole.
Slowly pull the recoil starter 2 or 3 times
so oil will evenly coat the interior of the
engine. Reinstall the spark plug.
 Before storing the unit, repair or replace
any worn or damaged parts.
 Remove the air cleaner element from the
carburetor and clean it thoroughly with
soap and water. Let dry and reassemble
the element.
 Store the unit in a clean,
dust-free area.
CAUTION!
Gasoline stored in the carburetor for
extended periods can cause hard start-
ing, and could also lead to increased
service and maintenance costs.
To remove the remaining fuel from the
fuel lines and carburetor and with the fuel
drained from the fuel tank.
1. Prime the primer bulb until no more fuel
is passing through.
2. Start and run the engine until stops run-
ning.
3. Repeat steps 1 and 2 until the engine will
no longer start.
