BEFORE STARTING
THE ENGINE
1. The area within a perimeter of
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

■ 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.

GB-15
G
B
EXZ2600DL
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.

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 into the start position. When starting the en-
gine, 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 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 (LINE HEAD USAGE)
WARNING
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 debris 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.
8. Operation (BC-EX only)
ADJUSTING THE LINE LENGTH
•Your brush cutters are equipped with a semi- auto
type nylon line head that allows the operator to ad-
vance 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 1 inch (25.4 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.

STARTING THE ENGINE
Please refer to 5. For safe operation (P. 7 ~ 9), 8. Ope-
ration (P. 15 ~ 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 into the start position. When starting the en-
gine, place the product onto the ground in a flat clear
area and hold it firmly in place to ensure that neither
the cutting part nor the throttle 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.
8. Operation (Optional blade usage BC-EX only)
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 shoulder strap, hang the unit on your right
side. Adjust the strap length so that the cutting head
may become parallel to the ground.
