Operating Precautions
WARNING!
■ Never transport the articulated
hedge trimmer or leave it unat-
tended with the engine running.
An engine that’s running could be
accidently accelerated causing the
blades to oscillate.
■ Immediately stop the engine with
the stop switch if the machine sud-
denly begins to vibrate or shake.
■ Make sure there is always good
ventilation when operating the artic-
ulated hedge trimmer. Fumes from
engine exhaust can cause seri-
ous injury or death. Never run the
engine indoors!
■ Always stop the engine imme-
diately and check for damage if
you strike a foreign object or if the
machine becomes tangled. Do not
operate with broken or damaged
equipment.
■ Make sure that the blade cover is in
place when transporting or storing
the articulated hedge trimmer.
■ Never smoke or light fires near the
hedge trimmer. Keep the unit away
from excessive heat. Engine fuel is
very flammable and fire could lead
to serious personal injury or prop-
erty damage.
■ Always make sure that the cut-
ter attachment and all handles and
guards are properly installed and
firmly tightened before operation.
■ When cutting a branch that is
under tension, be alert for spring-
back so that you will not be struck
by the moving branch.
■ Make sure the cutters are cor-
rectly adjusted before operating the
articulated hedge trimmer (see the
section ”Cutter Blade Adjustment”
for cutter adjustment procedures).
Never attempt cutter adjustment
with the engine running!
■ Inspect for broken, missing or
improperly installed parts or
attachments.
■ If a cutter should bind fast in a cut,
shut off the engine immediately.

the bind and free the cutter.
■ Never use a cracked or warped cut-
ter or cutter bar: replace it with a
serviceable one and make sure it
fits properly.
■ Always stop the engine and allow
it to cool before refueling. Avoid
overfilling and wipe off any fuel
that may have spilled.
■ Before starting the engine, make
sure the cutter is not contacting
anything.
■ Make sure there are no missing or
loose fasteners, and that the stop
switch and throttle controls are work-
ing properly.
■ To reduce fire hazard, keep the
engine and muffler free of debris,
leaves, or excessive grease.
■ Always confirm safe operation
when using the machine.

Mixing Fuel
WARNING!
Alternative fuels, such as E15 (15% ethanol), E-85 (85% ethanol) or any fuels not meeting Shindaiwa
requirements are NOT approved for use in Shindaiwa gasoline engines. Use of alternative fuels may cause
performance problems, loss of power, overheating, fuel vapor lock, and unintended machine operation, including,
but not limited to, improper clutch engagement. Alternative fuels may also cause premature deterioration of fuel
lines, gaskets, carburetors and other engine components.
Fuel Requirements
Gasoline - Use 89 Octane [R+M/2] (mid grade or higher) gasoline known to be good quality. Gasoline may contain
up to 10% Ethanol (grain alcohol) or 15% MTBE (methyl tertiary-butyl ether). Gasoline containing methanol (wood
alcohol) is NOT approved.
2 Stroke Mixture Oil - A 2-stroke engine oil meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD standards
must be used. Shindaiwa OneTM 2-Stroke Oil is strongly recommended as it meets this standard and is specifically
formulated for use in all Shindaiwa 2-stroke engines. Engine problems due to inadequate lubrication caused by fail-
ure to use an ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD certified oil will void the engine warranty.
For increased engine protection, Shindaiwa recommends using Shindaiwa Red ArmorTM engine oil to protect the engine from
harmful carbon build up, maintain engine performance, and increase engine life. Shindaiwa Red ArmorTM engine oil exceeds
ISO-L-EGD and J.A.S.O. M345/FD performance requirements.
Examples of 50:1 mixing quantities
IMPORTANT!
Shindaiwa OneTM 2-Stroke oil or Red ArmorTM engine oil may be mixed at 50:1
ratio for application in all Shindaiwa engines sold in the past, regardless of ratio
specified in those manuals.
IMPORTANT!
Stored fuel ages. Do not mix more fuel than you expect to use in thirty (30)
days, ninety (90) days when a fuel stabilizer is added. Use of unmixed, improp-
erly mixed, or stale fuel, may cause hard starting, poor performance, or severe
engine damage and void the product warranty. Read and follow instructions in
the Long Term Storage section of this manual.
Handling Fuel
DANGER
Fuel is VERY flammable. Use extreme care when mixing, storing or handling or serious personal injury may result.
• Use an approved fuel container.
• DO NOT smoke near fuel.
• DO NOT allow flames or sparks near fuel.
• Fuel tanks/cans may be under pressure. Always loosen fuel caps slowly allowing pressure to equalize.
• NEVER refuel a unit when the engine is HOT or RUNNING!
• DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks outdoors over bare ground.
• DO NOT overfill fuel tank. Wipe up spills immediately.
• Securely tighten fuel tank cap and close fuel container after refueling.
• Inspect for fuel leakage. If fuel leakage is found, do not start or operate unit until leakage is repaired.
• Move at least 3m (10 ft.) from refueling location before starting the engine.

Mixing Instructions
After use
1. Fill an approved fuel container with half of the
required amount of gasoline.
2. Add the proper amount of engine oil to gasoline.
3. Close container and shake to mix oil with gaso-
line.
• DO NOT store a unit with fuel in its tank. Leaks can
occur. Return unused fuel to an approved fuel stor-
age container.
Storage - Fuel storage laws vary by locality. Contact
your local government for the laws affecting your area.
As a precaution, store fuel in an approved, airtight
container. Store in a well-ventilated, unoccupied build-
ing, away from sparks and flames.
4. Add remaining gasoline, close fuel container, and
remix.
IMPORTANT!
Spilled fuel is a leading cause of hydrocarbon emissions.
Some states may require the use of automatic fuel shut-
off containers to reduce fuel spillage.
IMPORTANT!
Stored fuel may separate. ALWAYS shake fuel con-
tainer thoroughly before each use.

flat washers, and the flat washer be-
neath each bolt head should turn freely.
Cutting performance of your machine de-
pends a great deal on proper cutter blade
adjustment. Properly adjusted blades will
oscillate freely yet help prevent binding
of cut material between blades. Adjust
blades as follows:

Carburetor Adjustment
Engine Break-In
New engines must be operated a minimum duration of two tanks of fuel break-in before carburetor adjustments can be
made. During the break-in period your engine performance will increase and exhaust emissions will stabilize. Idle speed can
be adjusted as required.
High Altitude Operation
This engine has been factory adjusted to maintain satisfactory starting, emission, and durability performance up to
1,100 feet above sea level (ASL) (96.0 kPa). To maintain proper engine operation and emission compliance above
1,100 feet ASL the carburetor may need to be adjusted by an authorized Shindaiwa service dealer.
IMPORTANT!!
If the engine is adjusted for operation above 1,100 feet ASL, the carburetor must be re-adjusted when operating the
engine below 1,100 feet ASL, otherwise severe engine damage may result.
NOTE:
Every unit is run at the factory and the carburetor is set in compliance with emission regulations. Carburetor adjustments,
other than idle speed, must be performed by an authorized Shindaiwa dealer.
Adjusting Engine Idle
Idle Speed Adjustment
The engine must return to idle speed
whenever the throttle lever is re-
leased. Idle speed is adjustable, and
must be set low enough to permit the
engine clutch to disengage the cutting
attachment.
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 moves when the
engine is at idle, reduce the idle
speed by turning the idle adjust-
ment screw counter-clockwise.
WARNING!
The cutting attachment
must NEVER move at engine idle!
If the idle speed cannot be adjusted
by the procedure described here,
return the unit to your Shindaiwa
dealer for inspection.
3. If a tachometer is available, adjust
idle. Check Specifications page for
correct idle speed.

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:
■ Remove the spark plug and pour
about 1/4 oz. of engine 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.
CAUTION!
Gasoline stored in the carburetor
for extended periods can cause
hard starting, and could also lead to
increased service and maintenance
costs.
■ Clean external parts thoroughly and
apply a light coating of oil to all metal
surfaces.
■ Drain all the fuel from the carburetor
and the fuel tank.
■ Before storing the unit, repair or
