Do not use the unit where footing is unsteady
or slippery.

13. Keep cutting attachment below waist level.

14. Keep all parts of your body away from the
rotating cutting attachment and hot surfaces.

15. Warn the operator of the danger of blade
thrust. (Kick back)
Blade thrust may occur when the spinning
blade contacts a solid object in the critical
area. A dangerous reaction may occur causing
the entire unit and operator to be thrust
violently. This reaction is called Kick back. As a
result, the operator can lose control of the unit
which can cause serious or fatal injury. Kick
back is more likely to occur in areas where it is
difficult to see the material to be cut.

16. When inspecting or servicing the unit, make
sure to stop the engine and disconnect the
spark plug as necessary.

17. Cover the blade when the transporting or
storing the unit. Secure the unit before for
storage or transporting to prevent loss of fuel,
damage or injury.

18. When replacing cutting attachment or other
components, be sure to use the parts supplied
or recommended by ZENOAH.

19. When the unit is turned off, make sure the
cutting attachment has stopped before the unit
is set down.

20. For units equipped with a clutch, be sure the
cutting attachment stops turning when the
engine idles.

21. Use only for tasks explained in the instruction
handbook.

22. Discard blades that are bent, warped, cracked,
broken or damaged in any way.

23. Instructions on stopping a coasting blade.
A blade can injure while it continues to spin
after the engine is stopped or throttle control is
released.

24. Stop the engine and blade before removing
material that is blocking or entangling the
cutting attachment.

25. Use a sharp blade. A dull blade is more likely
to snag and thrust. Replace the fastening nut
according to the manufacturer's instruction.

26. Cut only material recommended by the
manufacturer. Do not let the blade contact
material it cannot cut, such as rocks, metal etc.

27. Always wear safety boots, additionally a
helmet is required if there is a risk of contact
with falling objects.

Setup

■ 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

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.
