SAFETY PRECAUTIONS
Please make sure you review each precaution carefully.
Pay special attention to statement preceded by the following words.
WARNING “WARNING” indicates a strong possibility of severe personal injury or loss
of life if instructions are not followed.
CAUTION “CAUTION” indicates a possibility of personal injury or equipment damage
if instructions are not followed.
: EXHAUST PRECAUTIONS
WARNING
■
Never inhale exhaust gasses.
They contain carbon monoxide, a colorless, odorless and extremely
dangerous gas which can cause unconsciousness or death.
■
■
■
Never operate the pump indoors or in a poorly ventilated area, such
as tunnel, cave, etc.
Exercise extreme care when operating the pump near people
or animals.
Keep the exhaust pipe free of foreign objects.
: REFUELING PRECAUTIONS
WARNING
■
Fuel is extremely flammable and its vapors can explode
if ignited.
■
■
■
Do not refuel indoors or in a poorly ventilated area.
Be sure to stop the pump prior to refueling.
Do not remove fuel tank cap nor fill fuel tank while engine is hot or
running. Allow engine to cool at least 2 minutes before refueling.
■
■
Do not overfill the fuel tank.
If fuel is spilt, wipe it away carefully and wait until the fuel has dried
before starting the engine.
■
After refueling, make sure that the fuel cap is secured to prevent
spillage.
: FIRE PREVENTION
WARNING
■
■
Do not operate the pump while smoking or near an open flame.
Do not use around dry brush, twigs, cloth rags, or other flammable
materials.
■
■
Keep cooling air intake (recoil starter area) and muffler side of the
engine at least 1 meter (3 feet) away from buildings, obstructions
and other burnable objects.
Keep the pump away from flammables and other hazardous
materials (trash, rags, lubricants, explosives).
1m
: OTHER SAFETY PRECAUTIONS
WARNING
■
■
Be careful of hot parts.
1m
The muffler and other engine parts become very hot while the
pump is running or just after it has stopped. Operate the pump
in a safe area and keep children away from the running pump.
Do not use diaphram pump for the mixture of water and oil.

■
■
Do not touch the ignition cable when starting and operating the
engine.
Operate the pump on a stable, level surface.
If the engine is tilted, fuel spillage may result.
NOTE
Operating the pump at a steep incline may cause seizure due
to improper lubrication even with a maximum oil level.
■
■
Do not transport the pump with fuel in tank or with fuel strainer cock open.
Keep the unit dry (do not operate it in rainy conditions).
: PRE-OPERATION CHECKS
CAUTION
■
■
Carefully check fuel hoses and joints for looseness and fuel leakage.
Leaked fuel creates a potentially dangerous situation.
Check bolts and nuts for looseness. A loose bolt or nut may cause
serious engine trouble.
■
■
Check the engine oil and refill if necessary.
Check the fuel level and refill if necessary.
Take care not to overfill the tank.
■
■
Keep cylinder fins and recoil starter free of dirt, grass and other debris.
Wear snug fitting working clothes when operating the engine.
Loose aprons, towels, belt, etc., may be caught in the engine or drive
train, causing a dangerous situation.

WARNING
Do not refuel while smoking, near an open
flame or other such potential fire hazards.
Otherwise fire accident may occur.
2. CONNECT SUCTION HOSE
2 w
(See Fig. - )
Use a reinforced-wall or wire braided hose to
prevent suction collapse.
■
Stop the engine and open the cap.
■
Use automotive unleaded gasoline only.
Since the pump self-priming time is directly
proportional to hose length, a short hose is
recommended.
This engine is certified to operate on automotive
unleaded gasoline.
Fuel Tank Capacity
Refer to “SPECIFICATIONS” Page 12 for fuel
tank capacity
CAUTION
Always use a strainer with the suction
hose. Gravel or debris sucked into the
pump will cause serious damage to the
impeller and the pump casting.
■
Close the fuel cock before filling the fuel tank.
■
Do not fill above the top of the fuel filter screen
(marked w), or the fuel may overflow when it
heats up later and expands.

6. CHECK PRIMING WATER
2 i
(See Fig. - )
4. CHECK ENGINE OIL
2 t
(See Fig. - )
It is recommended that the water chamber of pump
casing should be primed with full of water before
operating.
Before checking or refilling engine oil, be sure the
engine is located on stable, level surface and
stopped.
WARNING
Never attempt to operate the pump
without priming water or the pump will
overheat. Extended dry operation will
destroy the mechanical seal.
If the unit has been operated dry, stop the
engine immediately and allow the pump to
cool before adding priming water.
■
Do not screw the oil gauge into the oil filler neck
to check oil level. If the oil level is low, refill to the
upper level with the following recommended oil.
■
Use 4-stroke automotive detergent oil of API
service class SE or higher grade (SG, SH or SJ
is recommended).

1. STARTING (See Fig.
)
3. STOPPING (See Fig.
(1) Set the speed control lever at the low speed
position and allow the engine to run at low
speed for 1 or 2 minutes before stopping.
(See Fig. 5-q)
(1) Open the fuel cock. (See Fig. 3-q)
(2) Turn the STOP SWITCH to the position
“ I ” (ON). (See Fig. 3-w)
(3) Set the speed control lever 1/3 of the way
towards the high speed position.
(See Fig. 3-e)
(2) Turn the STOP SWITCH counterclockwise to
the position “ ” (OFF). (See Fig. 5-w)
(3) Close the fuel cock. (See Fig. 5-e)
(4) Close the choke lever. (See Fig. 3-r)
(4) Pull the starter handle slowly and return the
handle to its original position when resistance
is felt. This operation is necessary to prevent
outside moist air from intruding into the
combustion chamber. (See Fig. 5-r)
■
If the engine is cold or the ambient temperature
is low, close the choke lever fully.
■
If the engine is warm or the ambient
temperature is high, open the choke lever half-
way, or keep it fully open.
※
STOPPING ENGINE
WITH THE FUEL COCK
(5) Pull the starter handle slowly until resistance is
felt. This is the “compression” point. Return the
handle to its original position and pull swiftly.
Do not pull out the rope all the way. After
starting the engine, allow the starter handle to
return to its original position while still holding
the handle.(See Fig. 3-t)
Close the fuel cock and wait for a while until the
engine stops. Avoid to let the fuel remain in the
carburator over long periods, or the passages of the
carburator may become clogged with impurities,
and malfunctions may result.
(6) After starting the engine, gradually open choke
by turning the choke lever and finally keep it
fully opened. Do not fully open the choke lever
immediately when the engine is cold or the
ambient temperature is low, because the
engine may stop.(See Fig. 3-y)
MAINTENANCE

(See Fig. )
1. DAILY INSPECTION
Before running the engine, check the following
service items.
qLoose or broken bolts and nuts
wClean air cleaner element
eEnough clean engine oil
rLeakage of gasoline and engine oil
tEnough gasoline

2. RUNNING (See Fig.
)
(1) After the engine starts, set the speed control
lever at the low speed position (L) and warm it
up without load for a few minutes.
(See Fig. 4-q)
ySafe surroundings
(2) Gradually move the speed control lever toward
the high speed position (H) and set it at the
required engine speed.
uCheck the priming water
iExcessive vibration, noise
(See Fig. 4-w)
■
Whenever high speed operation is not required,
slow the engine down (idle) by moving the
speed control lever to save fuel and extend
engine life.

OIL SENSOR INSTRUCTIONS
1. FUNCTION OF OIL SENSOR
How to remove the spark arrester
1. Remove the flange bolts from the muffler cover
and remove the muffler cover.
The engine will stop automatically when the oil
level falls below the safety limit. The engine
cannot be started unless the level is raised above
the prescribed limit.
2. Remove the special screw from the spark
arrester and remove the spark arrester from
the muffler.

SPARK ARRESTER
The spark arrester must be free of breaks and
holes. Replace the spark arrester if it is damaged.
In a dry or wooded area, it is recommendable to
use the product with a spark arrester. Some
areas require the use of a spark arrester. Please
check your local laws and regulations before
operating your product.
SPARK ARESSTER SCREEN
The spark arrester must be cleaned regularly to
keep it functioning as designed. A clogged spark
arrester:

Prevents the flow of exhaust gas
■
Reduces engine output
Install the spark arrester, and muffler protector in
the reverse order of disassembly.
■
Increases fuel consumption
■
Makes starting difficult
If the engine has been running, the muffler and
the spark arrester will be very hot. Allow the
muffler to cool before cleaning the spark arrester.
