Be aware of the danger of  
falling debris.  
Keep bystanders at least  
50 feet (15 meters) away  
from the operating trimmer  
to reduce the risk of being  
cut by the cutting blades or  
struck by falling objects or  
thrown debris.  
The blades / cutting attach-  
ments are SHARP! Handle  
with care.  
Safety  
An articulated hedge trimmer has the  
potential to cause serious personal  
injury to the operator or bystanders  
if misused, abused or mishandled.  
To reduce the risk of injury, you must  
maintain control at all times, and  
observe all safety precautions during  
operation. Never permit a person with-  
out training or instruction to operate  
this trimmer!  
DAnGER!  
wARnInG!  
THE ARTICULATED  
Do not make unauthor-  
ized modifications or alterations to  
your articulated hedge trimmer or its  
components.  
HEDGE TRIMMER IS NOT INSULATED  
AGAINST ELECTRICAL SHOCK!  
Approaching or contacting electri-  
cal lines with the trimmer could  
cause death or serious injury.  
Keep the trimmer at least 10  
meters away from electrical lines  
or branches that contact electrical  
lines.  
wARnInG!  
Never operate this tool or any other  
power equipment if you are tired,  
ill, or under the influence of alcohol,  
drugs, or any substance that could  
affect your ability or judgement.  
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.  
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 articulated hedge trimmer.  
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!  
Always stop the engine and allow  
it to cool before refueling. Avoid  
overfilling and wipe off any fuel  
that may have spilled.  
Always make sure that the cut-  
ter attachment and all handles and  
guards are properly installed and  
firmly tightened before operation.  
To reduce fire hazard, keep the  
engine and muffler free of debris,  
leaves, or excessive grease  
Inspect for broken, missing or  
improperly installed parts or  
attachments.  
Before starting the engine, make  
sure the cutter is not contacting  
anything.  
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..  
Never use a cracked or warped cut-  
ter or cutter bar: replace it with a  
serviceable one and make sure it  
fits properly.  
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 artic-  
ulated hedge trimmer. Fumes from  
engine exhaust can cause serious  
injury or death. Never run the engine  
indoors!

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.  
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.  
Examples of 50:1 mixing quantities  
IMPORTAnT!  
Shindaiwa 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.

tion of this manual.  
After engine starts, move choke to OPEN  
position  
when the Engine Starts...  
After the engine starts, allow the  
engine to warm up at idle 2 or 3 min-  
utes before operating the unit.  
Advancing the throttle makes the cut-  
ting attachment move faster; releas-  
ing the throttle permits the attach-  
ment to stop moving. If the cutting  
attachment continues to move when  
the engine returns to idle, carburetor  
idle speed should be adjusted (see  
“Adjusting Engine Idle”.).  
If the engine does not start  
Repeat the appropriate starting pro-  
cedure for a cold or warm engine.  
If the engine does not continue to  
run, repeat the appropriate crank-  
ing procedures for a cold or warm  
engine.When the engine starts, clear  
excess fuel from the combustion  
chamber by accelerating the engine  
several times with the throttle lever.  
If the engine still fails to start,  
use the procedures for “Starting a  
flooded engine.”

Air Filter  
The H4 engine that powers your  
nOTE:  
Using non-standard replacement  
parts could invalidate your Shindaiwa  
warranty.  
Shindaiwa model is a hybrid 4-stroke  
engine. As a hybrid, the engine is lubri-  
cated by oil mixed with the gasoline  
and air from the carburetor 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.  
Muffler  
This unit must never be operated with  
a faulty or missing spark arrester or  
muffler. Make sure the muffler is well  
secured and in good condition. A worn  
or damaged muffler is a fire hazard and  
may also cause hearing loss.  
Spark Plug  
Keep the spark plug and wire connec-  
tions tight and clean.  
Daily maintenance  
Prior to each work day, perform the  
following:  
Cooling

Maintenance (continued)  
135-Hour Maintenance  
Replace the spark plug annually: Use  
only the type recommended in the  
”Specifications” section or an equiva-  
lent resistor type spark plug of the  
correct heat range. Set spark plug  
electrode gap to 0.6 mm.  
Combustion chamber should be  
decarbonized, and the valve clear-  
ance should be adjusted. It is highly  
recommended that this is done  
by a Shindaiwa-trained service  
technician.  
Valve Adjustment  
1. Remove cylinder cover, rocker arm  
cover, and spark plug. Rotate the  
crankshaft while observing the pis-  
ton through the spark plug opening.

compression stroke (TDC), the valves  
can be adjusted.  
CAUTIOn!  
Performing a valve adjustment  
incorrectly may cause hard  
starting and/or can damage the  
engine.  
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 tightening  
the locknut. Readjust as necessary.  
2. Loosen adjuster locknut so that the  
2.5 mm Allen socket head adjust-  
ment screw can turn freely.  
3. Insert 0.10 mm feeler gauge between  
valve stem tip and rocker arm.  
If you are unfamiliar with this  
engine or uncomfortable with  
this procedure, consult with an  
authorized Shindaiwa servicing  
dealer.

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, other-  
wise severe engine damage may result.
