■ 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.

As lot 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 fhe mixed gasoline, etc. described

therein, if may not be covered by the warranty.
