the engine is stopped.  
Be extremely careful  
of slippery terrain,  
especially during rainy  
weather.  
Be constantly alert for  
objects and debris that  
could be thrown either  
from the rotating cutting  
attachment or bounced  
from a hard surface.  
ALWAYS clear your work area of  
trash or hidden debris that could  
be thrown back at you or toward  
a bystander. When operating in  
rocky terrain or near electric wires  
or fences, use extreme caution to  
avoid contacting such items with  
the cutting attachment.  
If contact is made with a hard object,  
stop the engine and inspect the cutting

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.  
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.

IMPORTANT!  
Stored fuel may separate. ALWAYS shake fuel container  
thoroughly before each use.  
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.  
After use  
• DO NOT store a unit with fuel in its tank. Leaks can  
occur. Return unused fuel to an approved fuel storage  
container.

Cutting grass with a trimmer head  
Your Shindaiwa unit may be equipped  
with one of several Shindaiwa trimmer  
head models, each with features for  
specific applications and/or operational  
requirements.  
Trimmer head styles:  
NOTE:  
Semi-automatic. Trimmer line is  
indexed when the operator taps the  
trimmer head on the ground during  
operation.  
Additional hardware may be required to  
mount the Fixed Line or the Flail type  
trimmer heads.  
NOTE:  
Manual. The operator indexes line  
manually with the grass trimmer  
stopped.  
For proper operation, always refer to  
the instructions accompanying the trim-  
mer head being used.  
Fixed. The operator must stop the  
unit and add new lengths of trim-  
mer line manually.  
Flail. This device, designed for  
clearing weeds and light brush, fea-  
tures three nylon blades attached to  
the head by pivots.  
Engine Operating Speeds  
Operate at full throttle while cutting  
Cut from left to right  
grass.  
CAUTION!  
Use only flexible, nonmetallic line  
recommended by the manufacturer.  
Never use, for example, wire or  
wire-rope, which can break off and  
become a dangerous projectile.  
CAUTION!  
Operation at low rpm can lead to  
premature clutch failure.  
Return  
Cut  
Trimming and Mowing Grass  
Hold the grass trimmer so the trimmer  
head is angled slightly into the area to be  
cut. To ensure maximum trimmer-line ser-  
vice life, cut only with the tip of the trim-  
mer line. Cut grass by swinging the unit's  
trimmer head from left to right. Keep the  
trimmer head horizontal.  
WARNING!  
Remove all objects such  
as rocks, broken glass, nails, wire,  
or string, which can be thrown or  
become entangled in the cutting  
attachment.  
CAUTION!  
Operation of trimmer without a cut-  
ting attachment shield and using  
excessive line length can lead to  
premature clutch failure.  
CAUTION!  
Do not push the rotating line into  
trees, wire fences or any material  
that could tangle or break line ends.  
Operation at low rpm can lead to  
premature clutch failure.

Using a blade  
WARNING!  
Never use a blade for purposes  
other than those for which it was  
designed.  
A blade-equipped unit must be  
equipped with a bicycle-type  
handlebar or barrier bar as well  
as a harness or shoulder strap.  
Before working with a blade-  
equipped unit, always inspect and  
clear the area of objects that could  
interfere with or damage the blade.  
Whenever you strike a hard object  
with a blade, always stop the  
Always make sure the cutting  
attachment shield is properly  
installed before operating this  
unit.  
Never use a blade near sidewalks,  
fence posts, buildings or other  
objects that could cause injury or  
damage.  
brushcutter and carefully inspect  
the blade for damage. NEVER  
OPERATE THE BRUSHCUTTER  
WITH A DAMAGED BLADE!  
Blade Thrust  
Brushcutter Handlebar  
Engine Operating Speeds  
“Blade thrust” is a sudden sideways or  
backward motion of the brushcutter.  
Such motion may occur when the blade  
jams or catches on an object such  
as a sapling tree or tree stump. BE  
CONSTANTLY ALERT FOR BLADE  
THRUST AND GUARD AGAINST ITS  
EFFECTS!  
A brushcutter handlebar or barrier bar  
helps prevent the operator from mov-  
ing forward, or the unit moving rear-  
ward, thus preventing inadvertent  
bodily contact with the blade. ALWAYS  
KEEP THE HANDLEBAR OR BAR-  
RIER BAR SECURELY IN PLACE ON  
THE UNIT!  
Operate the unit at full throttle while cut-  
ting. Best fuel efficiency is obtained by  
releasing the throttle when swinging  
back after a cut.  
To prevent possible engine damage,  
do not allow the brushcutter to run  
at high speeds without a load.  
Brushcutter Shoulder Strap  
Avoid operating the engine at low  
speeds. Doing so can lead to rapid  
clutch wear. In addition, slow-speed  
operation tends to cause grass and  
debris to wrap around the cutting  
head.  
WARNING!  
Blade thrust can occur with-  
out warning if the blade snags,  
stalls or binds.  
A shoulder strap provides additional pro-  
tection against blade thrust. In addition,  
a shoulder strap gives significant support  
and comfort to help ensure safe and effi-  
cient operation. When operating a unit  
with a blade, make sure both the handle  
and shoulder strap are adjusted to the  
size of the operator using the unit.  
WARNING!  
Blade thrust is more likely to  
occur in areas where it is difficult to  
see the material being cut.  
Using a blade  
The blade rotates counter-clockwise. For best performance and to minimize  
being stuck by debris, move the blade from right to left while advancing on your  
work. Position the blade so cuts are made between the blade’s 8 o’clock and 10  
o’clock positions (as viewed from above). DO NOT cut between the 10 o’clock  
and 5 o’clock positions.

Air Filter  
The H4 engine that powers your  
Muffler  
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 adjust-  
ments. To keep your H4 engine strong  
and reliable, Shindaiwa recommends  
that you check and service the air fil-  
ter as instructed in the 10-Hour Mainte-  
nance section that follows.  
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.  
NOTE:  
Using non-standard replacement  
parts could invalidate your Shindaiwa  
warranty.  
Fasteners  
Make sure nuts, bolts, and screws  
(except carburetor adjusting screws)  
are tight.  
Daily maintenance  
Prior to each work day, perform the  
following:  
Remove all dirt and debris from the  
engine, check the cooling fins and  
air cleaner for clogging, and clean  
as necessary.  
Cooling  
fins  
Cooling  
fins  
Air  
intake  
Carefully remove any accumulations  
of dirt or debris from the muffler and  
fuel tank. Check cooling air intake  
area at base of crankcase. Remove  
all debris. Dirt build-up in these  
areas can lead to engine overheat-  
ing, fire, or premature wear.  
WARNING!  
Always wear gloves  
when working around the cutter  
assembly.  
Remove all dirt and debris from the engine and check the cooling fins  
Check the entire unit for leaking fuel  
or grease.  
Clean any debris or dirt from the

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.  
• Defects, malfunctions or failures resulting from abuse, misuse, neglect, modifications, alterations, normal wear, improper servic-  
ing, or use of unauthorized attachments.  
• Incorrect storage procedures, stale fuel, including failure to provide or perform required maintenance services as prescribed in  
the operator’s manual. Preventative maintenance as outlined in the operator’s manual is the customer’s responsibility.  
• Failures due to improper set-up, pre-delivery service or repair service by anyone other than authorized Shindaiwa servicing  
dealer during the warranty period.  
• Certain parts and other items are not warranted, including but not limited to: lubricants, starter cords, and engine tune-ups.  
• Use of spark plugs other than those meeting performance and durability requirements of the OEM spark plug listed in the Opera-  
tor’s Manuals.  
• Overheating or carbon scoring failures due to restricted, clogged exhaust port or combustion chamber, including damage to  
spark arrester screen.  
• Adjustments after the first (30) thirty days and beyond, such as carburetor adjustment and throttle cable adjustment.  
• Damage to gears or gear cases caused by contaminated grease or oil, use of incorrect type or viscosity of lubricants, and/or  
failure to comply with recommended grease or oil change intervals.  
• Damage caused by pump or sprayer running dry, pumping or spraying caustic or flammable materials, or lack of or broken  
strainers.  
• Additional damage to parts or components due to continued use after operational problem or failure occurs. Should operational  
problem or failure occur, the product should not be used, but delivered as is to an authorized Shindaiwa servicing dealer.  
It is a dealer’s and/or customer’s responsibility to complete and return the warranty registration card supplied with your Shindaiwa  
product or by visiting WWW.SHINDAIWA.COM. Your receipt of purchase including date, model and serial number must be main-  
tained and presented to an authorized Shindaiwa servicing dealer for warranty service. Proof of purchase rests solely with the cus-  
tomer. Some states do not allow limitations on how long an implied warranty lasts, so the above limitations may not apply to you.  
Some states do not allow the exclusion or limitation of incidental or consequential damages, so you may also have other specific  
legal rights which vary from state to state. This limited warranty is given by ECHO Incorporated, 400 Oakwood Rd., Lake Zurich, IL  
60047.
