Please make sureyou revieweach precautioncarefully.
SURROUNDINGS
m Operate the pump on a stable, level surfacefree of small rocks, loose gravel,
etc.
m Keep pumpat least 3 feet (1 meter)awayfrom buildings.
Keep pump away from flammables and other hazardous materials (trash,
rags, lubricants,explosives).
FIREPREVENTION
Be sureto stopthe engine priorto refueling.
m Do notoverfillfueltank.
m If spillage does occur, wipe away spilt fuel thoroughly and wait until fuel has
dried beforestartingengine.
m Do notoperatewhile smoking or near an open flame.
EXHAUSTPRECAUTION
Never inhale exhaust gasess; they contain carbon monoxide, a colorless,
odorless, extremely dangerous gas which can cause unconsciousness or
death.
m Never operate the pump indoors or in an enclosed area such as a cave or a
tunnel.
Exerciseextreme care when operatingnear peopleand domesticanimals.
OTHER IMPORTANTPOINTS
Keepaway from rotatingpartsand hot partswhile the pump is running.
m Never permitanyoneto operatethe pumpwithoutproperinstructions.
Know how to stop the pump quickly and understand operation of all the
controls.
Tightenthe fueltank cap securelyand closethe fuel cock beforetransit.
Neveroperatethe enginewith gasolineonly.
m Carefullycheckfuel pipesand jointsfor loosenessand fuel leakage.

3. PREPARATIONS FOR STARTING
1. Connectthe suction hose.
Use a reinforced-wallor wire braided hoseto
prevent suction collapse. Since the pump’s
self-priming time is directly proportional
to
hose length,a short hose is recommended.
[CAUTION]-
= Always use a strainer with the suc-
tion hose. Gravel or debris sucked
into the pump will cause serious
damage
to the impeller and the pump
casing.
2. Connectthe discharge hose.
When using a fabric hose, always use a hose band to prevent the hose from
disconnecting underhigh pressure.
3. Checkthe fuel level.
If levelis low,fillto the shoulder of the fuel filter.
Use the mixture fuel prepared by mixing gasoline and exclusive 2-cycle oil at
a
ratioof 20-25: 1, or the 2-cyclefuel now availableon the market.
1 Oil
20 to 25
Gasoline
CAUTION}
For break-in of a newengine
Use mixturefuelof gasoline 15-20:2-cycle engine oil
1 duringfirst 20
hoursof operation.

4. Checkthe prlming water.
It is recommendedthat the water chamber of
pump casing should be primed with full of
water beforeoperating.
+CAUTION]-,
Never attempt to operate the pump
without priming water or the pump
will overheat. Extended dry opera-
tion will destroy the mechanicalseal.
If the unit has been operated dry,
stop the engine immediately and al-
low the pump to cool before adding
primingwater.

4. STARTING THE ENGINE
1. Openthefuel cock.
2. Setthespeed control leverto “START.”
3. Closethe choke lever.
If the engine is warm or the ambient
temperature is high, close the choke
lever half-way,or keep
it open fully.
If the engine is cold, or the ambient
temperature
is low, close the choke
lever.
-5-

4. Pull the starter handle slowly until re-
sistance is felt. This is the "compression"
point. Return the handle to its original
positionand pullswiftly.
H Do not pullout the rope allthe way.
H After starting the engine, allow the
starter handle return to its original
positionwhile still holdingthe handle.
-6-

5. OPERATION
Avoid operatingthe engine at highspeedfor a longtime without load.
1. After starting the engine, gradually open
choke by turning the choke lever and
finally keepitopenfully.
Do not fully open the choke lever im-
mediately when the engine is cold or
the ambient temperature is low, be-
causethe engine may stop.
2. After the engine starts, set the speed
control lever at the low speed position
(L)
and warm it up without a load for a few
minutes.
Gradually move the speed control lever to-
ward the high speed position
(H) and set it at
the requiredenginespeed.
NOTE :
Whenever high speed operation is not re-
quired, slow the engine down (idle), by mov-
ing the speed control lever to save fuel and
extendengine life.

6. STOPPINGTHE ENGINE
1. Set the speed control lever to the low
speed position and allow the engine to
run at low speed for
2 or 3 minutes
beforestopping.
2. Keep depressing the STOP BUTTON
untilthe engine stops.
Do not stop the engine suddenly when it
is runningat highspeed.
3. Closethe fuel cock.
4. Pull the starter handle slowly and return
the handle to its original position when
resistance
is felt.
NOTE :
The above operation is necessary to prevent
outside moist air from intruding into the
combustionchamber.
STOPPINGENGINEWITH THE
FUEL COCK
Close the fuel cock and wait for a while until
the engine stops.
Avoid letting fuel remain in the carburetor
long period, or the passages
of the carbu-
retor may become clogged with impurities,
and malfunctionsmay result.

INSPECTING THE SPARK PLUG
Clean off carbon deposits on the plug
electrode using a plug cleaner or wire
brush.
w Check electrode gap.
Adjust itto between
0.02 and 0.03 inches.
(0.6 and 0.7mm)
CLEANING AIR CLEANER
Remove the element and clean it with kero-
sene. Then soak it in a mixture of
3 parts
kerosene and
1 part engine oil, squeeze out
the excess and installthe elenent.
0.6 to 0.7" -+-
(0.02 to 0.03 in.)

ELEMENT
CLEANING MUFFLER
If solid carbon deposits to the exhaust port of cylinder or both inlet and outlet of
the muffler to reduce these holes, it may cause a low output. In such a case,
removecarbon deposit after detachingthe muffler.
However, particularly by careful not to damage the piston and cylinder or not to
allow ingress
of carbon intothe crankcase.
FUEL PIPEREPLACEMENT
Replacethe fuel pipeevery 2 years.
If fuel leakage is found, replace it immediately.

WHEN ENGINEDOES NOT START:
fore you take the pump to your
Makita dealer.
If you still have trouble after com-
pleting the checks, take the pump
to your nearest Makitadealer.
Before testing, carefully wipe off
spilledfuel.
Put the plug as far away from the
spark plug holeas possible.
Ground the side of the electrode to
any engine ground.
r 1. Removethe plug and connect itto the plug cap.
Pull the starter- handle while putting the plug
againstthe engine ground.

3. The ignition system is faulty if there is no spark
with a new plug.
Take your pumpto your nearest Robin dealer.

4. if compression is still low, consult your nearest
dealer.
- 1. Choke (close choke lever) and pull the starter
handlefive or six times.
Remove the plug and check if its electrode is
wet. If the electrode is wet, fuel is well supplied
to your engine.
- 2. When the electrode is dry, check where the fuel
stops. (Check the fuel intake of the carburetor
and fuel strainer intake.)
3. In case the engine does not start with well
suppliedfuel, try using differentfuel.
