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 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.
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
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. GASOHOL – It can cause deterioration of rubber and/
2. 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.
G B
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.

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.
WARNING
CONTROLLING BLADE BOUNCE
• Kick out can cause serious personal injury. Carefully study this section. It is important that you understand what causes kick out, how you can reduce the chance of kick out and how you can remain in control of the unit if kick out does occur.
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.
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.
1. What causes kick out:
•Kick out 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 kick out:
a. Recognize that kick out can happen. By understand-
ing 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.
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.
GB-12
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. Tr y 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
IMPORTANT
Note that using any spark plug other than those desig-
nated 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.
AIR FILTER
• The air filter, if clogged, will reduce the engine perfor­mance. Check and clean the filter element in warm, soapy water as required. Dry completely before in­stalling. If the element is broken or shrunk, replace with a new one.
Air Filter
FUEL FILTER
• When the engine runs short of fuel supply, check the fuel cap and the fuel filter for blockage.
TIGHTENING TORQUE:
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.
SPARK ARRESTER
• The muffler is equipped with a spark arrester to pre­vent red hot carbon from flying out of the exhaust out­let. Periodically inspect and clean as necessary with a wire brush.
9.8 ~ 11.8 N.m. (1 ~ 1.2 kgm)
Spark arrester

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.
0.6~0.7 mm
• REPLACEMENT PLUG IS A NGK CMR7H.
GB-14
ANGLE TRANSMISSION
• The reduction gears are lubricated by multipurpose, lithium-based grease in the angle transmission. 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.
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.

9. Maintenance
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 which have attached themselves to the 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.

10. Storage
Aged fuel is one of major causes of engine starting fail­ure. Before storing the unit, empty the fuel tank and run the engine until it uses all the fuel left in the fuel line and the carburetor. Store the unit indoor taking necessary measures for rust prevention.
11. Disposal
When disposing your machine, fuel or oil for the machine, be sure to allow your local regulations.

PROCEDURES TO BE PERFORMED AFTER EVERY 100 HOURS OF USE
1. Remove the muffler, insert a screwdriver into the vent, and wipe away any carbon buildup. Wipe away any carbon buildup on the muffler exhaust vent and cylin­der exhaust port at the same time.
2. Tighten all screws, bolts, and fittings.
3. Check to see if any oil or grease has worked its way in between the clutch lining and drum, and if it has, wipe it away using oil-free, lead-free gasoline.
