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 imme-
diately. 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 vegeta-
tion, mud, etc

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
fueling 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.

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
operation, 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.

STARTING THE ENGINE
Please refer to 5. For safe operation (P. 7 ~ 9), 8. Ope-
ration (P. 16 ~ 17).
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
ensure that neither the cutting attachment nor the
throttle trigger come into contact with any obstacle
when the engine starts.
CUTTING METHOD
a) Use the front left side cutting.
b) Guide the blade from your right to left with it tilted
slightly to your left.
c) When mowing a wide area, start working from your
left end to avoid interference of cut grass.
d) The blade may be seized by weeds if the engine
speed is too low, or the blade cuts too deep into
weeds. Adjust the engine speed and cutting depth
according to the condition of object.
WARNING
•If the grass or other object gets caught in the blade,
or if the unit starts to shake or vibrate, turn off the
engine and check the whole unit. Change the blade
if it has been damaged.
•Turn off the engine and make sure the blade has
completely stopped before checking the blade, and
removing any object got caught in.
OPERATION
1. Check the bolt to fasten the blade and be sure the
bolt has no fault, and no abrasion.
2. Be sure that the blade and the holder have been fas-
tened according to instruction and that the blade turns
smoothly without abnormal noise.
WARNING
•The rotating parts fastened incorrectly may cause
serious accident to the operator.
•Make sure that the blade is not bent, warped,
cracked, broken or damaged.
•If you find any error to the blade, discard it and
replace with a new one, which is certified by
ZENOAH.
By using the harness, hang the unit on your right side.
Adjust the harness length so that the cutting head may
become parallel to the ground.
