15 m of the person using the
product should be considered a
hazardous area into which no one
should enter. If necessary, yellow
warning rope, warning signs
should be placed around the pe-
rimeter of the area. When work is
to be performed simultaneously
by two or more persons, care
should also be taken to constantly
look around or otherwise check
for the presence and locations of
other people working so as to
maintain a distance between
each person sufficient to ensure
safety.
2. Check the condition of working
area to avoid any accident by hit-
ting hidden obstacles such as
stumps, stones, cans, or broken
glass.
IMPORTANT
Remove any obstacle before begin-
ning work.

waist high.
STARTING THE ENGINE
1. Keep bystanders and animals at
least 15 m away from the operat-
ing point. If you are approached,
immediately stop the engine.
2. The product is equipped with a
centrifugal clutch mechanism, so
the cutting attachment begins to
rotate as soon as the engine is
started by putting the throttle trig-
ger into the start position. When
starting the engine, place the
product onto the ground in a flat
clear area and hold it firmly in
place so as to ensure that neither
the cutting part nor the throttle
trigger come into contact with any
obstacle when the engine starts.
WARNING

into the high-speed position when
starting the engine.
3. After starting the engine, check
to make sure that the cutting at-
tachment stops rotating when the
throttle is moved fully back to its
original position. If it continues to
rotate even after the throttle trig-
ger has been moved fully back,
turn off the engine and take the
unit to your authorized ZENOAH
servicing dealer for repair.
USING THE PRODUCT
IMPORTANT

KICKBACK SAFETY PRECAU-
TIONS FOR CHAIN SAW USERS
WARNING
•Kickback may occur when the
nose or tip of the guide bar
touches an object, or when the
wood closes in and pinches the
saw chain in the cut. Tip contact
in some cases may cause a light-
ning fast reverse reaction,kicking
the guide bar up and back to-
wards the operator. Pinching the
saw chain along the top of the
guide bar may push the guide
bar rapidly back towards the
operator. Either of these reac-
tions may cause you to Iose con-
trol of the saw, which could re-
sult in serious personal injury.
•Do not rely exclusively on the
safety devices built into your saw.
As a chain saw user you should
take several steps to keep cut-
ting jobs free from accident or
injury.
(1) With a basic understanding of
kickback you can reduce or
eliminate the element of surprise.
Sudden surprise contributes to
accidents.
(2) Keep a good grip on the saw with
both hands, the right hand on the
rear handle, and the left hand on
the front handle, when the engine
is running. Use a firm grip with
thumbs and fingers encircling
the chain saw handles. A firm
grip will help you reduce kick-
back and maintain control of the
saw.
(3) Make certain that the area in
which you are cutting is free from
obstructions. Do not let the nose
of the guide bar contact a log,
branch, or any other obstruction
which could be hit while you are
operating the saw.
(4) Cut at high engine speeds.
(5) Follow the manufacturer’s sharp-
ening and maintenance instruc-
tions for the saw chain.
(6) Only use replacement bars and
chains specified by the manufac-
turer or the equivalent.
WARNING
•Make sure the chain and sprocket
are correctly adjusted before op-
erating the pruner (see page
13~14 for adjustment proce-
dures). Never attempt chain ad-
justment with the engine running!
•Always make sure the cutting at-
tachment is properly installed and
firmly tightened before operation.
•Never use a cracked or warped
guide bar: replace it with a ser-
viceable one and make sure it fits
properly.
•If a saw chain should bind fast in
a cut, shut off the engine immedi-
ately. Push the branch or tree to
ease the bind and free the saw
chain.
•Do not operate the pruner with the
muffler removed.
•When cutting a limb that is under
tension, be alert for springback so
that you will not be struck by the
moving limb.
•Always stop the engine immedi-
ately and check for damage if you
strike a foreign object or if the ma-
chine becomes tangled. Do not
operate with broken or damaged
equipment.
IMPORTANT
•Do not make unauthorized modi-
fications or substitutions to the
guide bar or chain.
•Never allow the engine to run at
high RPM without a load. Doing
so could damage the engine.
•Keep the pruner as clean as pos-
sible. Keep it free of loose veg-
etation, mud, etc

7. Fuel and chain oil
4. Pour in the rest of gasoline and agitate again for at
least one minute. As some oils may be difficult to
agitate depending on oil ingredients, sufficient agi-
tation is necessary for the engine to last long. Be
careful that, if the agitation is insufficient, there is an
increased danger of early piston seizing due to ab-
normally lean mixture.
5.
Put a clear indication on the outside of the container
to avoid mixing up with gasoline or other containers.
6. Indicate the contents on outside of container for easy
identification.
■ FUELING THE UNIT
1. Untwist and remove the fuel cap. Rest the cap on a
dustless place.
2. Put fuel into the fuel tank to 80% of the full capacity.
3. Fasten the fuel cap securely and wipe up any fuel
spillage around the unit.
WARNING
1. Select flat and bare ground for fueling.
2. Move at least 10 feet (3 meters) away from the fu-
eling point before starting the engine.
3. Stop the engine before refueling the unit. At that
time, be sure to sufficiently agitate the mixed gaso-
line in the container.
■ FOR YOUR ENGINE LIFE, AVOID:
1. FUEL WITH NO OIL (RAW GASOLINE) – It will cause
severe damage to the internal engine parts very quickly.
2. GASOHOL – It can cause deterioration of rubber and/
or plastic parts and disruption of engine lubrication.
3. OIL FOR 4-CYCLE ENGINE USE – It can cause spark
plug fouling, exhaust port blocking, or piston ring stick-
ing.
4. Mixed fuels which have been left unused for a pe-
riod of one month or more may clog the carburetor
and result in the engine failing to operate properly.
5. In the case of storing the product for a long period of
time, clean the fuel tank after rendering it empty. Next,
activate the engine and empty the carburetor of the
composite fuel.
6. In the case of scrapping the used mixed oil container,
scrap it only at an authorized repository site.
NOTE
As for details of quality assurance, read the description
in the section Limited Warranty carefully. Moreover, nor-
mal wear and change in product with no functional influ-
ence are not covered by the warranty. Also, be careful
that, if the usage in the instruction manual is not observed
as to the mixed gasoline, etc. described therein, it may
not be covered by the warranty.
■ CHAIN OIL
Use motor oil SAE #10W-30 all year round or SAE
#30 ~ #40 in summer and SAE #20 in winter.
NOTE
Do not use wasted or regenerated oil that can cause
damage to the oil pump.
■ FUEL
WARNING
•Gasoline is very flammable. Avoid smoking or
bringing any flame or sparks near fuel. Make sure
to stop the engine and allow it cool before refuel-
ing the unit. Select outdoor bare ground for fueling
and move at least 3 m (10 ft) away from the fueling
point before starting the engine.
•The Zenoah engines are lubricated by oil specially
formulated for air-cooled 2-cycle gasoline engine use.
If Zenoah oil is not available, use an anti-oxidant added
quality oil expressly labeled for air-cooled 2-cycle en-
gine use (JASO FC GRADE OIL or ISO EGC GRADE).
•Do not use BIA or TCW (2-stroke water-cooling type)
mixed oil.
■RECOMMENDED MIXING RATIO
GASOLINE 50 : OIL 1
(when using ZENOAH genuine oil)
•Exhaust emission are controlled by the funda-
mental engine parameters and components (eq.,
carburation, ignition timing and port timing) with-
out addition of any major hardware or the introduc-
tion of an inert material during combustion.
•These engines are certified to operate on unleaded
gasoline.
•Make sure to use gasoline with a minimum octane
number of 89RON (USA/Canada: 87AL).
•If you use a gasoline of a lower octane value than pre-
scribed, there is a danger that the engine tempera-
ture may rise and an engine problem such as piston
seizing may consequently occur.
•Unleaded gasoline is recommended to reduce the
contamination of the air for the sake of your health and
the environment.
•Poor quality gasolines or oils may damage sealing
rings, fuel lines or fuel tank of the engine.
■ HOW TO MIX FUEL
WARNING
•Pay attention to agitation.
1. Measure out the quantities of gasoline and oil to be
mixed.
2. Put some of the gasoline into a clean, approved fuel
container.
3. Pour in all of the oil and agitate well.

Place the unit on a flat, firm place.
Keep the cutting head clear of everything around it.
6. While holding the unit firmly, pull out the starter rope
quickly until engine fires.
WARNING
The product is equipped with a centrifugal clutch
mechanism, so the cutting attachment begins to ro-
tate as soon as the engine is started by putting the
throttle trigger into the start position. When starting
the engine, place the product onto the ground in a
flat clear area and hold it firmly in place so as to en-
sure that neither the cutting attachment nor the
throttle trigger come into contact with any obstacle
when the engine starts.
IMPORTANT
•Avoid pulling the rope to its end or returning it by re-
leasing the knob. Such actions can cause starter fail-
ures.

CUTTING WORK (TRIMMER HEAD USAGE)
WARNING
1. Always wear eye protection such as safety
goggles. Never lean over the rotating cutting at-
tachment. Rocks or other debris could be thrown
into eyes and face and cause serious personal in-
jury.
2. Keep the cutting attachment guard in place at all
times when the unit is operated.
TRIMMING GRASS AND WEEDS
•Always remember that the TIP of the line does cut-
ting. You will achieve better results by not crowding
the line into the cutting area. Allow the unit to trim at
its own pace.
1. Hold the unit so the head is off the ground and is tilted
about 20 degrees toward the sweep direction.
2. You can avoid thrown debris by sweeping from your
left to the right.
3. Use a slow, deliberate action to cut heavy growth.
The rate of cutting motion will depend on the material
being cut. Heavy growth will require slower action than
will light growth.
4. Never swing the unit so hard as you are in danger of
losing your balance or control of the unit.
5. Try to control the cutting motion with the hip rather
than placing the full workload on the arm and hands.
6. Take precautions to avoid wire, grass and dead, dry,
long-stem weeds from wrapping around the head
shaft. Such materials can stall the head and cause
the clutch to slip, resulting in damage to the clutch
system if repeated frequently.
ADJUSTING THE LINE LENGTH
•Your brush cutter is equipped with a semi- auto type
nylon line head that allows the operator to advance
the line without stopping the engine. When the line
becomes short, lightly tap the head on the ground
while running the engine at full throttle.
•Each time the head is bumped, the line advances
about 25 mm. For better effect, tap the head on bear
ground or hard soil. Avoid bumping in thick, tall grass
as the engine may stall by overload.
•Make the right and left lines the same length when
using the nylon line head.
(Be sure to install the genuine Zenoah cutting attach-
ment guard when using the nylon line head.)
•If the lengths of the right and left lines are different,
the balance of the nylon line head will be disrupted,
resulting in increased vibration and product damage.
•If you feel a vibration increase or shaft tube shaking
while using the nylon line head, immediately stop op-
eration, check the following items, and correct any
problems.
The lengths of the right and left lines are significantly
different.
-->Make them the same length.
The cover is removed.
-->Make sure to install it securely.
There is a crack or damage outside.
-->Replace the damaged part.
•If vibration or shaking persists even after repairing, or
if you cannot identify the cause of abnormality, con-
tact your local authorized Zenoah dealer for repair.
•Never continue to operate the unit when vibration or
shaking of the shaft tube persists.
