Mixing Fuel
CAUTION!
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. 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 C4 engines, and should never
be used in your Shindaiwa engine.
Filling the Fuel Tank
WARNING!
Minimize the risk of re!
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.
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
with a pump octane of 87 or higher.
Mix all fuel with a 2-cycle air-cooled
mixing oil that meets or exceeds ISO-LEGD and/or JASO FC classified oils at
50:1 gasoline/oil ratio.
NEVER start or operate this unit if
the carburetor, fuel lines, fuel tank
and/or fuel tank cap are damaged.
NEVER smoke or light any res

with left hand. Use your other hand to
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!
6. When the engine starts, slowly move the
choke lever to the “OPEN” position. See
Figure 13. (If the engine stops after the
initial start, close the choke and restart.)
Open
WARNING! Never start the engine from the operating position.
7. Operating the throttle will automatically
disengage the fast idle setting.
IMPORTANT!
If the engine fails to start after several attempts with the choke in the closed posi-
tion, the engine may be ooded with fuel.
If ooding 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 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 “Adjusting
Engine Idle” below).
4. Set the choke lever to the CLOSED
position if engine is cold.

Checking Unit Condition
NEVER operate the unit with the cutting
attachment shield or other protective
devices removed!
WARNING!
A cutting attachment shield or
other protective device is no guarantee
of protection against ricochet. YOU
MUST ALWAYS GUARD AGAINST
FLYING DEBRIS!
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!
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.
Use only authorized Shindaiwa parts and
accessories with your Shindaiwa trimmer. Do
not make modifications to this unit without
written approval from Shindaiwa, Inc.
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 attachment
holder. If a properly installed attachment
vibrates, replace the attachment with new
one and re-check.
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 15.
3. If a tachometer is available, the engine idle
speed should be final adjusted to 3,000
(±300) rpm (min-1).
4. Carburetor fuel mixture adjustments are
preset at factory and cannot be serviced
in the field.
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.
NEVER allow the engine to run at high
RPM without a load. Doing so could
damage the engine.
NEVER operate a unit with worn or
damaged fasteners or attachment holders.

Using a Hand-held Edger
26021
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.
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 running at about half-throttle. Slowly lower
the blade to the ground while applying
full throttle. See Figure 16.
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.
Do not pull the unit backward over the
ground with the engine running. Doing
so will tend to bury the blade.
Regular and frequent use of the edger
will make a neater lawn, and a frequently
trimmed edge will be easier to maintain.
Figure 16
WARNING!
Wear eye protection, long pants, and
boots when operating this machine
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!

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.
See Figure 17.
2. Raise or lower the guide wheel to the
desired setting. See Figure 17a.
3. Tighten the guide wheel adjusting knob
firmly. See Figure 17.
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
edger blades.
