7. Fuel
■ FUEL
• 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 refueling 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 2cycle engine 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 fundamental engine parameters and components (eq.,
carburation, ignition timing and port timing) without addition of any major hardware or the introduction 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
prescribed, there is a danger that the engine temperature 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
•
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 agitation 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 abnormally 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.
1. Select bare ground for fueling.
2. Move at least 3 meters (10 feet ) 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 gasoline 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 sticking.
4. Mixed fuels which have been left unused for a
period 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.
• As for details of quality assurance, read the description in the section Limited Warranty carefully. Moreover, normal wear and change in product with no
functional influence 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.
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.

cracked, broken or damaged.
• If you find any error to the blade, discard it and
change 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.
• Warm up the engine before adjusting the idling speed.
WARNING
CUTTER APPLICATION CHART
• Replace by a suitable recommended cutting attachment according to the object to be cut.
• Make sure to use harness and cutting attachment
guard. If not, it is very dangerous when you slip or
lose your balance.
• When replacing blade always be sure to use products
which have been certified by ZENOAH.
WARNING
• When sharpening, removing, or reattaching the
blade, be sure to wear thick, sturdy gloves and
use only proper tools and equipment to prevent
injury.

8. Operation
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 stop before checking the blade, and
removing any object got caught in.
d. Keep the blade sharp. A dull blade increase the
chance of bounce.
e. Avoid feeding the blade too rapidly. The blade can
bounce away from material being cut if the blade is
fed faster than its cutting capability.
f. Cut only from your right to your left.
g. Keep your path of advance clear of material that has
been cut and other debris.
3. How you can maintain the best control:
a. Keep a good, firm grip on the unit with both hands. A
firm grip can help neutralize bounce. Keep your right
and left hands completely around the respective
handles.
b. Keep both feet spread apart in a comfortable stance
and yet braced for the possibility that the unit could
bounce. Do not overreach. Keep firm footing and
balance.
CUTTING WORK (TRIMMER HEAD USAGE)
WARNING
WARNING
CONTROLLING BLADE BOUNCE
• Blade thrust can cause serious personal injury. Carefully study this section. It is important that you understand what causes blade thrust, how you can reduce
the chance of blade thrust and how you can remain
in control of the unit if blade thrust does occur.
1. What causes blade thrust:
• Blade thrust can occur when the moving blade contacts an
object that it cannot cut. This contact causes the blade to
stop for an instant and then suddenly move or ”bounce”
away from the object that was hit. The operator can lose
control of the unit and the blade can cause serious personal injury to the operator or any person nearby if the blade
contacts any part of the body.
2. How you can reduce the chance of blade
thrust:
a. Recognize that blade thrust can happen. By understanding and knowing about bounce, you can help eliminate the
element of surprise.
b. Cut fibrous weeds and grass only. Do not let the blade contact materials it cannot cut such as hard, woody vines and
brush or rocks, fences, metal, etc.
c. Be extra prepared for bounce if you must cut where you
cannot see the blade making contact such as in areas of
dense growth.
GB-14
1. Always wear eye protection such as safety
goggles. Never lean over the rotating cutting head.
Rocks or other debris could be thrown into eyes
and face and cause serious personal injury.
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 cutting. 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.
BCZ4000DL / BCZ4000DW / BCZ4200CL
8. Operation
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 attachment 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.
G
B
• 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, contact your local authorized Zenoah dealer for repair.
• Never continue to operate the unit when vibration or
shaking of the shaft tube persists.

REFILLING TRIMMING LINE
1. For replacement line, use a diameter of 2.4mm(.095in).
The spool is capable for a line upto 6m(20ft) on the
10cm(4”) head. Avoid using a larger line as it may cut
down the trimming performance.
BLADE
• Check the blade and the fasteners for looseness,
cracking, or bending.
• Check the cutting edges and reform with a flat file.
WARNING
• For safety reasons, do not use metalreinforced
line.
2. Pinch the slotted area on the both sides of the spool
housing to unhook the bottom cap.
3. Take out the spool and pull off the old line. Put one
end of new line through the spool holes and pull it
until the length is equal between each part of the line.
4. Wind up the line in the correct direction as indicated
on the spool.
5. Hook each end of the line in the slot on the edge of
the spool, and then put the ends through the eyelets
on the housing. Make sure that the spring and the
washers are in place.
6. While holding the spool against the housing, pull the
line ends to release them from the slot.
7. Line up the slot on the bottom cap with the hook on
the housing, press the cap against the housing until it
clicks.
Point :
1. Keep the end corner sharp.
2. Round the root of the edge, using round file.
3. Do not use water when using a grinder.
• It is recommended that filing should be done by
professionals.
• Especially regarding filing the saw blade, Leave it to the
professionals.
WARNING
• Make sure that the engine has stopped and is cool before performing any service to the machine. Contact with
moving cutting head or hot muffler may result in a personal injury.
