gasoline may cause increased operating temperatures. Under certain
conditions, alcohol-based gasoline
may also reduce the lubricating
qualities of some 2-cycle mixing oils.
n 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.
n Use only fresh, clean unleaded gasoline
with a pump octane of 87 or higher.
low emissions engines. Shindaiwa One also
includes a fuel stabilizer.
n Mixed with 50:1 Shindaiwa ISO-L-EGD
or JASO FC class 2-cycle mixing oil at a
gasoline/ratio of 50:1 (1 gallon of gasoline to 2.6 ozs mixing oil). Shindaiwa One
meets or exceeds these requirements.
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™.
Examples of 50:1 mixing quantities
n 1 gallon of gasoline to 2.6 oz. mixing oil.
n 5 liters of gasoline to 100 ml. mixing oil.

one hand, slowly pull the recoil starter
handle until resistance is felt, then pull
quickly to start the engine.
CAUTION!
Do not pull the recoil starter to the end
of the rope travel. Pulling the recoil
starter to the end of the rope travel can
damage the starter.
WARNING!
The cutting attachment may rotate
when the engine is started!
IMPORTANT!
If the engine fails to start after several
attempts with the choke in the closed position, 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.
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 cutting 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.
Stopping the Engine
Idle the engine briefly before stopping
(about 2 minutes), then slide the ignition
switch to the “O” (engine OFF) position.
See Figure 19.
Figure 19
Adjusting Engine Idle
Idle Adjusting
Screw
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.
Idle Speed Adjustment
WARNING!
Figure 20
The cutting attachment must NEVER
rotate at engine idle! If the idle speed
cannot be adjusted by the procedure
described here, return the trimmer to
your Shindaiwa dealer for inspection.
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 attachment rotates when the
engine is at idle, reduce the idle speed
by turning the idle adjustment screw
counter-clockwise. See Figure 20.
3. If a tachometer is available, the engine idle
speed should be final adjusted to 2,750
(±250) RPM (min-1).
4. Carburetor fuel mixture adjustments are
preset at factory and cannot be serviced
in the field.
Checking Unit Condition
NEVER operate the unit with the cutting
attachment shield or other protective devices (ignition switch, etc.) removed!
WARNING!
A cutting attachment shield or other
protective device is no guarantee of
protection against ricochet. YOU MUST
ALWAYS GUARD AGAINST FLYING
DEBRIS!
Use only authorized Shindaiwa parts and
accessories with your Shindaiwa trimmer.
Do not make modifications to your unit
without the written approval of Shindaiwa
Inc.

Using a Hand-Held Edger
Guidelines for Operating the Edger.
 Before edging, make sure the area is
soft enough so the blade does not bog
down. If necessary, water the area before edging.
WARNING!
n Wear eye protection, long pants,
and boots when operating this unit!
 Remove debris and other obstacles that
could be thrown by the rotating blade.
n 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!
 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 running at about half-throttle. Slowly lower
the blade to the ground while applying full
throttle. See Figure 21.
CAUTION!
Low-speed edging can lead to premature clutch failure.
 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.
