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.  
Push the branch or tree to ease  
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.  
Keep a Solid Stance. Maintain  
footing and balance at all times.  
Do not stand on slippery, uneven  
or unstable surfaces. Do not work  
in odd positions or on ladders. Do  
not over reach.  
WARNING!  
Moving parts can amputate fingers or cause severe injuries. Keep hands, clothing and loose objects away  
from all openings.  
ALWAYS stop engine, disconnect spark plug, and make sure all moving parts have come to a complete stop  
before removing obstructions, clearing debris, or servicing unit.  
DO NOT start or operate unit unless all guards and protective covers are properly assembled to unit.  
NEVER reach into any opening while the engine is running. Moving parts may not be visible through openings.  
WARNING!

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.

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.

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

ATTENTION ENGINE POWERED PRODUCT OWNERS  
This Shindaiwa engine powered product is a quality-engineered unit which has been manufactured to exact tolerances to provide  
superior performance. To help ensure the performance of the unit, it is required to use engine oil which meets the ISO-L-EGD  
Standard per ISO/CD 13738 and JASO M345/FD Standards. Shindaiwa Red ArmorTM and Shindaiwa OneTM are a premium engine  
oil specifically formulated to meet ISO-L-EGD (ISO/CD 13738) and JASO M345/FD Standards. The use of engine oils designed  
for other applications, such as for outboard motors or lawnmowers can result in severe engine damage, and will void your engine  
limited warranty.  
THIS WARRANTY DOES NOT COVER DAMAGE CAUSED BY:  
• Lack of lubrication or engine failure, due to the use of engine oils that do not meet the ISO-L-EGD (ISO/CD 13738) and JASO  
M345/FD Standards. Shindaiwa Red ArmorTM and Shindaiwa OneTM Engine Oil meets the ISO-L-EGD and JASO M345/FD  
Standard. Emission related parts are covered for 2 years regardless of engine oil used, per the statement listed in the EPA or  
California Emission Control Warranty Explanation.  
• Damage caused by use of gasohol, containing methanol (wood alcohol), or gasoline containing less than 89 octane. Only use  
gasoline which contains 89 octane or higher. Gasohol which contains a maximum 10% ethanol (grain alcohol) or 15% MTBE  
(methyl/tertiary/butyl/ether) is also approved. The prescribed mixing ratio of gasoline to oil is listed on the Shindaiwa oil label and  
covered in your operator’s manual.  
• Engine damage caused by use of ether or any starting fluids.  
• Damage caused by tampering with engine speed governor or emission components, or running engines above specified and  
recommended engine speeds as listed in your operator’s manual.  
• Operation of the unit with improperly maintained/removed cutting shield or removed/damaged air filter.  
• Damage caused by dirt, pressure or steam cleaning the unit, salt water, corrosion, rust, varnish, abrasives, and moisture.
