Operating Precautions  
WARNING!  
Never transport the hedge trim-  
mer or leave it unattended with the  
engine running. An engine that’s  
running could be accidently acceler-  
ated causing the blades to oscillate.  
When cutting a branch that is  
under tension, be alert for spring-  
back so that you will not be struck  
by the moving branch.  
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.  
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.  
Make sure that the blade cover is in  
place when transporting or storing  
the hedge trimmer.  
Make sure the cutters are cor-  
rectly adjusted before operating  
the hedge trimmer (see the sec-  
tion ”Blades” for cutter adjustment  
procedures). Never attempt cutter  
adjustment with the engine running!  
Always make sure that the cut-  
ter attachment and all handles and  
guards are properly installed and  
firmly tightened before operation.  
Always stop the engine and allow  
it to cool before refueling. Avoid  
overfilling and wipe off any fuel  
that may have spilled.  
Inspect for broken, missing or  
improperly installed parts or  
attachments.  
To reduce fire hazard, keep the  
engine and muffler free of debris,  
leaves, or excessive grease  
Before starting the engine, make  
sure the cutter is not contacting  
anything.  
Never use a cracked or warped cut-  
ter or cutter bar: replace it with a  
serviceable one and make sure it  
fits properly.  
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.  
Always confirm safe operation  
when using the machine.  
Immediately stop the engine with  
the stop switch if the machine sud-  
denly begins to vibrate or shake.  
Make sure there are no missing or  
loose fasteners, and that the stop  
switch and throttle controls are work-  
ing properly.  
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 there is always good  
ventilation when operating the  
hedge trimmer. Fumes from engine  
exhaust can cause serious injury or  
death. Never run the engine indoors!  
WARNING!  
Hedge Clipper blades are very sharp. Touching them may lead to severe personal injury. Avoid touching  
blades whenever possible, and always wear gloves to protect hands  
CAUTION!  
Do not make unauthorized modifi-  
cations to the hedge trimmer or its  
components.  
Always stop the engine and allow  
it to cool before refueling. Avoid  
overfilling and wipe off any fuel  
that may have spilled.  
Always maintain the hedge trim-  
mer according to this owner’s man-  
ual and follow the recommended  
scheduled maintenance.  
Keep the cutters sharp and prop-  
erly adjusted.  
Never place flammable material  
close to the engine muffler and  
never run the engine without the  
spark arrestor screen in place.  
Never allow the engine to run at  
high speed without a load. Doing  
so could damage the engine.  
Never modify or disable any of the  
hedge trimmer’s safety devices.  
Doing so may cause damage and  
lead to personal injury  
Always clear your work area of  
trash or hidden debris to help  
ensure good footing.  
When transporting the hedge  
trimmer in a vehicle, tie it down  
securely to prevent fuel spillage or  
damage to the machine.  
Always use genuine Shindaiwa  
parts and accessories when repair-  
ing or maintaining this 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 opera-  
tion, including, but not limited to, improper clutch engagement. Alternative fuels may also cause premature dete-  
rioration 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.  
Hybrid 4TM Mixture Oil - Engine oil meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD standards must be  
used. Shindaiwa highly recommends using Shindaiwa Red ArmorTM engine oil in all Shindaiwa Hybrid 4TM engines 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. Engine problems  
due to inadequate lubrication caused by failure to use an ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD certified  
oil will void the engine warranty.  
IMPORTANT!  
Shindaiwa Red ArmorTM engine oil may be mixed at 50:1 ratio for application in all Shindaiwa engines sold in the past, re-  
gardless of ratio specified in those manuals.

IMPORTANT!  
Examples of 50:1 mixing quantities  
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  
Storage - Fuel storage laws vary by  
locality. Contact your local govern-  
ment for the laws affecting your area.  
As a precaution, store fuel in an ap-  
proved, airtight container. Store in a  
well-ventilated, unoccupied building,  
away from sparks and flames.  
1. Fill an approved fuel container with half of the required amount of  
2. gasoline.  
3. Add the proper amount of engine oil to gasoline.  
4. Close container and shake to mix oil with gasoline.  
5. 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 container thoroughly be-  
fore each use.  
After use  
• DO NOT store a unit with fuel in its tank. Leaks can occur. Return unused  
fuel to an approved fuel storage container.

Maintenance and Adjustments  
IMPORTANT!  
Maintenance, replacement or repair of emission control devices and systems may be performed by any repair establish-  
ment or individual; however, warranty repairs must be performed by a dealer or service center authorized by ECHO, Inc. .  
The use of parts that are not equivalent in performance and durability to authorized parts may impair the effectiveness of the  
emission control system and may have a bearing on the outcome of a warranty claim.  
NOTE:  
Using non-standard replacement parts  
could invalidate your Shindaiwa warranty.  
Air Filter  
The H4 engine that powers your Shindaiwa model is a hybrid 4-stroke engine. As a  
hybrid, the engine is lubricated by oil mixed with the gasoline and air from the carbure-  
tor that moves through and around the internal parts of the engine in a similar way that  
a 2-stroke engine is lubricated. Without the heavy duty 2-stage air filter equipped on all  
H4 engines, dust and dirt could also move through the engine, decreasing engine life,  
increasing valve wear and the need for more frequent valve adjustments. To keep your  
H4 engine strong and reliable, Shindaiwa recommends that you check and service the  
air filter as instructed in the 10-Hour Maintenance section that follows.

135-Hour or Annual Maintenance  
Combustion chamber should be decarbonized, and the valve clearance should be adjusted. It is highly recommended  
that this is done by a Shindaiwa-trained service technician.  
Replace the spark plug annually: Use only NGK CMR5H or equivalent resistor type spark plug of the correct heat range.  
Set spark plug electrode gap to 0.6 mm.  
NOTE:  
The NGK CMR5H also meets the requirements for electro magnetic compliance (EMC).  
CAUTION!  
Performing a valve adjustment incorrectly may cause hard starting and/or can damage the unit. Refer to the Service  
Manual for complete valve adjustment procedure and torque specifications.  
If you are unfamiliar with this engine or uncomfortable with this procedure, Consult with an authorized Shindaiwa servic-  
ing dealer.

Valve Adjustment  
1. Remove cylinder cover, rocker arm cover, and set piston at TDC-compression.  
2. Loosen adjuster locknut so that the  
2.5 mm Allen socket head adjustment screw can turn freely.  
3. Insert feeler gauge .004 (0.10 mm) for both intake and exhaust; between valve  
stem tip and rocker arm.  
4. Turn adjustment screw (clockwise = tighter, counter-clockwise = looser) until  
feeler gauge is almost snug. Back off just enough to allow gauge to slip out with  
limited resistance.  
Figure 23  
5. While holding adjustment screw in place with Allen driver, tighten locknut with wrench.  
6. Turn engine over several times, and return to TDC-compression. Recheck with proper  
feeler gauge to make sure clearance adjustment did not change as a result of tighten-  
ing locknut. Readjust as necessary.  
7. Replace rocker arm cover gasket to assure proper sealing and install cover.  
IMPORTANT!  
If new gasket is not available and/or old gasket is not damaged, old gasket may  
be reused. Never use cracked or damaged gaskets!

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.

Idle Adjustment  
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 cutters.  
Idle Speed Adjustment  
1. Start the engine, and then allow it to idle 2–3 minutes until warm.  
2. If the cutters move when the engine is at idle, reduce idle speed by turning the  
idle adjustment screw counterclockwise.  
3. If a tachometer is available, adjust idle. Check Specifications page for correct  
idle speed.  
Figure 10  
4. Carburetor fuel mixture adjustments are preset at the factory and cannot be  
adjusted or serviced in the field.  
WARNING!  
The cutters must NEVER engage at engine idle speeds! If the idle speed can-  
not be adjusted by the above procedure, return the trimmer to your Shindaiwa  
dealer for inspection.  
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
