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.

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

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.

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.
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.
