6. Set up  
IMPORTANT  
NOTE  
Discharge port angle can be changed to 3 different  
directions. Adjust to your operating condition.  
• As a suction hose, be sure to use suction hose(nominal  
diameter 25mm) or an equivalent ‘water suction hose’  
only.  
• Securely connect hoses with attached hose couplings  
and clumps.  
• If the suction hose connection is loose, or a packing  
in hose coupling has been lost or damaged, air may  
be sucked into the pump and interrupt water suction  
(air lock).  
4. Submerge the suction hose strainer in the water.  
5. Lay the discharge hose where necessary. Arrange  
protective covers if the hose can be disturbed by foot  
steps of others.  
6. Remove self-suction plug and top up the pump with water.  
• A strainer shall be placed so that it does not appear  
above water level nor suck bottom sand and mud.  
a
1. Place your pump at nearby water resource horizon-  
tally.  
a. Self-suction port  
2. Insert hose couplings to the suction hose and dis-  
charge hose and tighten them with clumps.  
3. After checking the packing of each hose coupling,  
connect the suction hose to a suction port and the  
discharge hose to a discharge port.

7. Fuel  
FUEL  
Exhaust emission are controlled by the funda-  
mental engine parameters and components (eq.,  
carburation, ignition timing and port timing) with-  
out addition of any major hardware or the intro-  
duction of an inert material during combustion.  
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 refuel-  
ing the unit. Select outdoor bare ground for fuel-  
ing and move at least 3 m (10 ft) away from the  
fueling point before starting the engine.  
• 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 tem-  
perature 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.  
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 en-  
gine use (JASO FC GRADE OIL or ISO EGC GRADE).  
Do not use BIA or TCW (2-stroke water-cooling type) mixed oil.  
HOW TO MIX FUEL  
WARNING  
• 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.  
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 nec-  
essary 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.  
RECOMMENDED MIXING RATIO  
GASOLINE 50 : OIL 1  
(when using ZENOAH genuine oil)  
GB-6  
 
PE2300  
7. Fuel  
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.  
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 stick-  
ing.  
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.  
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.

WARNING  
6. In the case of scrapping the used mixed oil container,  
scrap it only at an authorized repository site.  
1. Select bare ground for fueling.  
2. Move at least 3 meters (10 feet ) away from the fuel-  
ing point before starting the engine.  
NOTE  
3. Stop the engine before refueling the unit. At that time,  
be sure to sufficiently agitate the mixed gasoline in  
the container.  
• As for details of quality assurance, read the descrip-  
tion in the section Limited Warranty carefully. More-  
over, normal wear and change in product with no func-  
tional 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. de-  
scribed therein, it may not be covered by the war-  
ranty.  
FOR YOUR ENGINE LIFE, AVOID:  
1. FUEL WITH NO OIL (RAW GASOLINE) – It will cause  
severe damage to the internal engine parts very  
quickly.  
8. Operation  
WARNING  
• Confirm that the suction hose connection is not too  
loose. Loose connection may result in no suction wa-  
ter.  
• In case the discharge hose is clogged or a valve con-  
nected to the discharge hose is closed, the pump  
may not suck water.  
Highly combustible. When refueling, switch the en-  
gine off and keep well away from naked flames.  
After filling the tank with fuel, firmly tighten the  
cap.  
• Stepping on the discharge hose or sudden closure of  
the discharge valve may create instantaneous high  
pressure in the pump and result in pump  
damage(Water Hammer Effect). Arrange protective  
covers if the hose can be disturbed by others step-  
ping on, and avoid closing the valve rapidly.

WARNING  
• Before starting the engine, check if there is anything  
that must not be wet near the discharge hose tip. Give  
warning to nearby people of starting water discharge.  
IMPORTANT  
• Idle operation with no water in the pump may cause  
pump damage. Before starting the engine, check if  
the pump is filled with self-suction(priming) water. In  
case the suction strainer comes out of the water level  
during operation, immediately reduce the engine  
speed and stop the operation.

9. Maintenance  
INTAKE AIR COOLING VENT  
WARNING  
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.  
Never touch the cylinder, muffler, or spark plugs with  
your bare hands immediately after stopping the en-  
gine. The engine can become very hot when in op-  
eration, and doing so could result in severe burns.  
G
B
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 muf-  
fler 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.  
(1) Intake air cooling vent  
Check the intake air cooling vent and the area  
around the cylinder cooling fins after every 25 hours  
of use for blockage. Note that it is necessary to re-  
move the upper cover and the lower cover in order  
to be able to view the upper part of the cylinder.  
10. Storage  
WARNING  
2. Drain the fuel tank and fill the pump with water  
• When draining fuel, please be careful not to spill it. If  
fuel is spilt, wipe off thoroughly. In addition, please be  
sure to close the storage container cap tightly.  
IMPORTANT  
• If fuel is left in the engine for protracted periods, the  
inside of the carburetor may become clogged and  
cause engine malfunction (faulty starting and insuffi-  
cient output).  
• During storage, slightly loosen the cap of the fuel tank.  
If screwed too tightly, the gasket may become dis-  
torted.  
3. Start the engine, and leave it in idling condition until  
all the fuel inside the carburetor is spent and the en-  
gine comes to a natural stop.  
4. Remove the spark plug and put a few drops (1 to 2 cc)  
of 2-cycle oil inside the engine. After pulling the starter  
rope 2 or 3 times, return the spark plugs to their origi-  
nal position and stop in compressed position.  
5. Drain water from the pump completely, and wipe off  
water on the pump using dry cloth.  
On completion of all work procedures, when not plan-  
ning to use again for a protracted period please carry  
out the following pre-storage care, to prevent trouble  
caused by time-lapse changes.  
1. Remove dirt from the pump, inspect it for any dam-  
age or looseness, and, if any abnormality is found,  
correct it thoroughly in preparation for the next time  
you use the unit.  
6. After oiling the throttle lever and other metal parts with  
anti-corrosive oil, cover the pump and store indoors  
in a low-humidity location.
