INSTALLING BLADE
Remove the guard skirt of debris guard, when
using metal blade.
1. Put the angled bar(1) into the
side holes of the inner holder
and the gearcase.
2. Remove the nut(Left-handed)
and the outer holder(3) from
the gearshaft.
3. Put the blade onto the inner
holder(2). Make the marked
side face the holder.
4. Put the outer holder(3) onto
the gearshaft making the
recessed side face the blade.
5. Fasten the blade by the nut and the cover(4).
■
BALANCE UNIT
1. Put on strap and attach
unit to strap.
2. Slide clamp up or down
until unit balances with
head aparting from the
ground when using it.
• 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 3m (10ft) 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 engine
use. (JASO FC GRADE OIL or ISO EGC
GRADE)
• Do not use BIA or TCW (2-stroke water-cooling
type) mixed 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 89 RON (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
Pay attention to agitation.
IMPORTANT
WARNING
[BC3501LE/WE/BC4501WE]
• Using attached 4 socket screws, secure the
connection firmly with equal force.
■
HANDLE
[BC2311LE/BC2611LE/BC3501LE]
• Put the handle onto the main pipe and fix it with
4 screws.
[BC2611WE/BC3501WE/BC4501WE]
1. Loosen the 4 bolts on the upper cap and insert
the handles equally. Retighten the bolts.
2. Put the handle assembly into the bracket and
put the upper cap over it. Tighten the cap
securely.
■
CONNECTING THROTTLE WIRE
1. Remove the air cleaner cover.
2. Connect the end of the throttle wire to the joint
on the top of the carburetor.
■
CONNECTING SWITCH WIRES
• Connect the switch wires between the engine
and the main unit.
■
PROTECTOR
[BC2611WE/BC3501WE/BC4501WE]
• Wrap the protector around the outer pipe as
shown in the figure, and fasten the magic
fastener.
■
INSTALLING DEBRIS GUARD
1. Fit the guard skirt on debris guard.
2.
[BC2311LE/BC2611]
Attach the debris guard with the bolts provided
while inserting the spacer between the guard
and the pipe.
[BC3501/BC4501WE]
Attach the debris guard with the bolts provided
to the pipe.
■
INSTALLING LINE HEAD
1. While locking the gear shaft by inserting the
angled bar(1) into the holder(A)(2) on the gear
box, loosen and remove the nut(left-handed)
2. Fit the line head assembly to the gear shaft.
Tighten it securely by hand.
■
STARTING ENGINE
The cutting head will start rotating upon the
engine starts.
1. Feed fuel into the fuel tank and tighten the cap
securely.
2. Rest the unit on a flat, firm place. Keep the
cutting head off the ground and clear of
surrounding objects, as it will start rotating upon
starting of the engine.
3. Push the primer pump several times until
overflown fuel flows out in the clear tube.

RECOMMENDED MIXING RATIO
GASOLINE 50:OIL 1
(when using ZENOAH genuine oil)
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.
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 10feet (3meters) 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.
