Safety (continued)
The Properly Equipped Operator
Always wear eye protection such as
goggles or safety glasses to shield
against thrown objects.
Wear hearing protection devices and a
broad-brimmed hat or helmet. A helmet
is required when using a blade-equipped
brushcutter to clear small trees.
Always wear a harness when operating the unit .
It adds comfort and helps ensure safety by limiting
movement fore and aft. When the harness is
adjusted properly, the unit should balance with the
cutting attachment parallel to the ground.
Prolonged exposure to excessive noise
is fatiguing and could lead to impaired
hearing.
Always operate with both hands
firmly gripping the unit.
Wear close-fitting clothing to
protect legs and arms. Gloves
offer added protection and are
strongly recommended. Do not
wear clothing or jewelry that
could get caught in machinery
or underbrush. Secure long hair
so that it is above shoulder level.
NEVER wear shorts!
When operating with a blade, make sure
the handle is positioned to provide you with
maximum protection from contacting the
blade. Always make sure the handlebar
is installed in accordance with the
manufacturers instructions.
Always make sure
the appropriate cutting
attachment shield is correctly
installed and in good
condition. Do not
operate the unit if the
cutting attachment
shield is missing,
loose, or broken.
Keep away from the rotating
trimmer line or blade at all
times, and never lift a moving
attachment above waist-high.
Long-term exposure to vibration
can damage your hands.
Keep a proper footing and do not
overreach. Maintain your balance at all
times during operation.
Wear appropriate footwear (non-skid
boots or shoes): do not wear opentoed shoes or sandals. Never work
barefooted!
Be Aware of the Working Environment
Avoid long-term
operation in very hot
or very cold weather.
Be extremely careful
of slippery terrain,
especially during rainy
weather.
Reduce the risk of bystanders
being struck by flying debris. Make
sure no one is within 15 meters
(50 feet)— that’s about 16 paces
of an operating attachment. Stop
immediately if a child, pet, or
person comes within a 15 meter
(50 feet)radius. Outside this radius,
there is still a risk of injury from
thrown objects.
Make sure
bystanders
or observers
outside the
15 meter (50
feet) “danger
zone” wear eye
protection.
Always make sure
the appropriate
cutting attachment
shield is correctly
installed.
15 METERS
(50 FEET)
Be constantly alert for
objects and debris that
could be thrown either
from the rotating cutting
attachment or bounced
from a hard surface.
If contact is made with a hard object,
stop the engine and inspect the cutting
attachment for damage.
4
Do not operate the unit
if the cutting attachment
shield is missing, loose,
or broken.
Beware of a coasting
blade when brushcutting or
edging. A coasting blade
can injure while it continues
to spin after the throttle
trigger is released or after
the engine is stopped.
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.

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.
IMPORTANT!
Examples of 50:1 mixing quantities
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, improperly 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.
10
Mixing Instructions
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 gasoline.
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 shutoff containers to reduce fuel spillage.
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 building,
away from sparks and flames.
IMPORTANT!
Stored fuel may separate. ALWAYS shake fuel container
thoroughly before 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.
Filling the fuel tank
WARNING!
Minimize the Risk of Fire
■■NEVER smoke or light fires near the
engine.
■■ALWAYS stop the engine and allow
it to cool before refueling.
■■ALWAYS Wipe all spilled fuel and
move at least 3 meters (10 feet) from
the fueling point and source before
starting.
■■NEVER place flammable material
close to the engine muffler.
■■NEVER operate the engine without the
muffler and spark arrester screen in
place and in good working condition.
■■FUEL IS HIGHLY FLAMMABLE.
■■ALWAYS store gasoline in a con-
tainer approved for flammable liquids.
■■ALWAYS inspect the unit for fuel
leaks before each use. During each
refill, check that no fuel leaks from
around the fuel cap and/or fuel tank. If
fuel leaks are evident, stop using the
unit immediately. Fuel leaks must be
repaired before using the unit.
■■ALWAYS move the unit at least 3
meters (10 feet) away from a fuel
storage area or other readily flammable materials before starting the
engine.
1. Place the unit on a flat, level
surface.
2. Clear any dirt or other debris
from around the fuel filler cap.
CAUTION!
Slowly remove the fuel cap
only after stopping the engine
3. Remove the fuel cap, and fill
the tank with clean, fresh fuel.
4. Reinstall the fuel filler cap and
tighten firmly.
5. Wipe away any spilled fuel
before starting engine.

Shoulder strap
WARNING!
Always wear a shoulder
strap or harness when operating
this unit. Using a harness with a
brushcutter allows you to maintain proper control of the unit and
reduces fatigue during extended
operation.
1. Hook the strap hook to the hanger
on the outer tube.
2. Wear the shoulder strap so that the
hook stays at your right hand side.
3. Adjust the length of the shoulder
strap so that you can hold and operate the machine comfortably.
IMPORTANT!
Adjust the shoulder strap so the
shoulder pad rests comfortably on the
off-side shoulder and the cutting path
of the cutting attachment is parallel to
the ground. Make sure all hooks and
adjustment devices are secure.
Shoulder strap

NOTE:
Using a shoulder strap when operating this unit with a blade allows you
to maintain proper control of the unit
and reduces fatigue during extended
operation.
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.
NOTE:
For proper operation, always refer to
the instructions accompanying the trimmer head being used.
Trimmer head styles:
Semi-automatic. Trimmer line is
indexed when the operator taps the
trimmer head on the ground during
operation.
Manual. The operator indexes line
manually with the grass trimmer
stopped.
Fixed. The operator must stop the
unit and add new lengths of trimmer line manually.
Flail. This device, designed for
clearing weeds and light brush, features three nylon blades attached to
the head by pivots.
NOTE:
Additional hardware may be required to
mount the Fixed Line or the Flail type
trimmer heads.

Engine Operating Speeds
Operate at full throttle while cutting
grass.
CAUTION!
Cut from left to right
Cut
Return
Operation at low rpm can lead to
premature clutch failure.
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 service life, cut only with the tip of the trimmer line. Cut grass by swinging the unit's
trimmer head from left to right. Keep the
trimmer head horizontal.
CAUTION!
Do not push the rotating line into
trees, wire fences or any material
that could tangle or break line ends.
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!
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 of trimmer without a cut-
ting attachment shield and using
excessive line length can lead to
premature clutch failure.
■■Operation at low rpm can lead to
premature clutch failure.
Using a blade
WARNING!
■■Before working with a blade-
equipped unit, always inspect and
clean the area of objects that could
interfere with or damage the blade.
■■Never use a blade near sidewalks,
fence posts, buildings or other
objects that could cause injury or
damage.
Blade Thrust
“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!
WARNING!
Blade thrust can occur without warning if the blade
snags, stalls or binds.
■■Never use a blade for purposes
other than those for which it was
designed.
■■Whenever you strike a hard object
with a blade, always stop the
brushcutter and carefully inspect
the blade for damage. NEVER
OPERATE THE BRUSHCUTTER
WITH A DAMAGED BLADE!
WARNING!
Blade thrust is more likely to
occur in areas where it is difficult to
see the material being cut.
Brushcutter Handlebar
A brushcutter handlebar or barrier bar
helps prevent the operator from moving forward, or the unit moving rearward, thus preventing inadvertent
bodily contact with the blade. ALWAYS
KEEP THE HANDLEBAR OR BARRIER BAR SECURELY IN PLACE ON
THE UNIT!
■■A blade-equipped unit must be
equipped with a bicycle-type
handlebar or barrier bar as well
as a harness or shoulder strap.
■■Always make sure the cutting
attachment shield is properly
installed before operating this
unit.
Brushcutter Shoulder Strap
A shoulder strap provides additional protection against blade thrust. In addition,
a shoulder strap gives significant support
and comfort to help ensure safe and efficient 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.
Engine Operating Speeds
Operate the unit at full throttle while cutting. 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.
■■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.
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
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

Fasteners
Make sure nuts, bolts, and screws
(except carburetor adjusting screws)
are tight.
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 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.
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.
