7. Fuel

■ 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 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 funda-

mental 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

IMPORTANT

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.

GB-10

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.

WARNING

1. Select 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 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 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, 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.

8. Operation

STARTING ENGINE

WARNING

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.

WARNING

The product is equipped with a centrifugal clutch mechanism, so the cutting attachment begins to rotate as soon as the engine is started by putting the throttle 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 part nor the throttle come into contact with any obstacle when the engine starts.

8. Operation

ADJUSTING THROTTLE CABLE

• The normal play is 1 or 2 mm when measured at the carburetor side end. Readjust with the cable adjuster as required.

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.

.04 in

(1 ~ 2 mm)

(1) Cable adjuster

ADJUSTING IDLING SPEED

(1)

(1) Idle adjusting screw

1. When the engine tends to stop frequently at idling mode, turn the adjusting screw clockwise.

2. When the cutting head keeps rotating after releasing the trigger, turn the adjusting screw counter-clockwise.

NOTE

• Warm up the engine before adjusting the idling speed.

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 cutting attachment guard in place at all times when the unit is operated.

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.

9. Maintenance

SPARK PLUG

• Starting failure and misfiring are often caused by a fouled spark plug. Clean the spark plug and check that the plug gap is in the correct range. For a replacement plug, use the correct type specified by

ZENOAH.

GEAR CASE

• The reduction gears are lubricated by multipurpose, lithium-based grease in the gear case. Supply new grease every 25 hours of use or more often depending on the job condition.

• Remove the bolt opposit to the grease nipple before installing new grease to arrange for old grease to exit.

0.6~0.7 mm

• REPLACEMENT PLUG IS A NGK BPMR7A.

IMPORTANT

• Note that using any spark plug other than those designated may result in the engine failing to operate properly or in the engine becoming overheated and damaged.

• To install the spark plug, first turn the plug until it is finger tight, then tighten it a quarter turn more with a socket wrench.

TIGHTENING TORQUE:

150 ~ 220 kgf-cm

(14.7 ~ 21.6 N.m.)

MUFFLER

WARNING

• Inspect periodically, the muffler for loose fasteners, any damage or corrosion. If any sign of exhaust leakage is found, stop using the machine and have it repaired immediately.

• Note that failing to do so may result in the engine

catching on fire.

INTAKE AIR COOLING VENT

WARNING

• Never touch the cylinder, muffler, or spark plugs

with your bare hands immediately after stopping the engine. The engine can become very hot when in operation, and doing so could result in severe burns.

• When checking the machine to make sure that it

is okay before using it, check the area around the muffler and remove any wood chips or leaves w h i c h h a v e a t t a c h e d t h e m s e l v e s t o t h e brushcutter. Failing to do so could cause the muffler to become overheated and that in turn could cause the engine to catch on fire. Always make sure that the muffler is clean and free of wood chips, leaves, and other waste before use.

• Check the intake air cooling vent and the area around the cylinder cooling fins after every 25 hours of use for blockage, and remove any waste which has attached itself to the brushcutter. Note that it is necessary to remove the engine cover shown in (MA5) in order to be able to view the upper part of the cylinder.

IMPORTANT

• If waste gets stuck and causes blockage around the intake air cooling vent or between the cylinder fins, it may cause the engine to overheat, and that in turn may cause mechanical failure on the part of the brushcutter.
