lm PUMP SAFETY
Pleasemakesure you revieweach precautioncarefully.
SURROUNDINGS
Operate the pump on a stable, level surface free of small rocks, loose gravel,
etc.
Keep pumpat least 3 feet (1 meter)awayfrom buildings.
Keep pump away from flammables and other hazardous materials (trash,
rags,lubricants,explosives).
FIRE PREVENTION
m Besure to stopthe engine priorto refueling.
m Do notoverfillfueltank.
m If spillage does occur, wipe away spilt fuel thoroughly and wait until fuel has
dried beforestartingengine.
Do notoperatewhile smoking or near an openflame.
EXHAUSTPRECAUTION
Never inhale exhaust gasess ; they contain carbon monoxide, a colorless,
odorless, extremely dangerous gas which can cause unconsciousness or
death.
Never operate the pump indoors or in an enclosed area such as a cave or a
tunnel.
w Exerciseextremecare when operating near peopleand domestic animals.
OTHER IMPORTANT POINTS
Keepaway from rotatingpartsand hot partswhile the pumpis running.
Neverpermitanyoneto operatethe pumpwithout proper instructions.
Know how to stop the pump quickly and understand operation of all the
controls.
Tightenthefuel tank cap securelyand closethe fuel cock beforetransit.
Checkthe engine oil and refillif necessary.
Carefullycheckfuel pipesandjointsfor loosenessandfuel leakage.

3. PREPARATIONSFOR STARTING
1 Connectthe suction hose.
Use a reinforced-wallor wire braided hose to
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
damageto the impellerand 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. Check the engine oil level.
Engineoil is a majorfactor affectingengine performanceand service life.
Nondetergentor vegetableoils are not recommended.
Useoil classified
“SC” or highergrade.
If the oil levelis belowthe fill levellineon the dipstick, refillwith the properoil (see
table)to edge of the oilfuller neck.
Besureto checkthe oil levelon a levelsurfacewith the engine stopped.

4. Checkthe fuel level.
If level is low, fill to the shoulder of the fuel filter. Use fresh, clean automotive
gasoline.
5. Checkthe primingwater.
It is recommendedthat the water chamber of
pump casing should be primed with full of
water beforeoperating.
[CAUTIONI-l
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. STARTINGTHE ENGINE
1. Openthe fuel cock.
2. Setthe speed 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 keepitopen fully.
m 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.
Do not pulloutthe rope allthe way.
After starting the engine, allow the
starter handle return to its original
positionwhile still holdingthe handle.
-6-

5. OPERATION
1. After starting the engine, gradually open
choke by turning the choke lever and
finally keepit openfully.
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.
-7-

6. STOPPING THE 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 BUlTON
untilthe engine stops.
Do not stop the engine suddenly when it
is runningat highspeed.
3. Closethefuel cock.
4. Pull the starter handle slowly and return
the handle to its original position when
resistanceisfelt.
NOTE :
The above operation is necessary to prevent
outside moist air from intruding into the
combustionchamber.
STOPPING ENGINEWITH THE FUEL COCK
Closethe fuel cock and wait for a while untilthe engine stops.
Avoid letting fuel remain in the carburetor long period, or the passages
of the
carburetor may becomecloggedwith impurities,and malfunctions may result.

INSPECTINGTHE SPARK PLUG
w 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 0.7")
ENGINEOIL CHANGE
w Initialoil change ...... 20 hoursof operation
m Thereafter.. . Every 50 hours of operation
[CAUTION}-,
Make sure the fuel cap is tightly se-
curedto avoidspillage.
w When changing oil, stop the engine
and loosenthe drain plug.
Tightenthe drainplugbeforerefilling.
w Refer to the recommended oil table
on page
3.
Always use the proper grade and
clean oil.
If the engine oil is contam-
inated, there is not enough or
it is of
poor quality, engine
life will be short-
ened.

CLEANING FUELSTRAINER
Checkfor water or contaminants inthe fuel strairler.
To removecontaminants,close the fuelcock and remove the strainer cup.
w After removingcontaminantsand water, wash the strainercup with kerosene.
Reinstallit securely
to prevent leakage.

SERVICING THE AIR CLEANER
Maintainingan air cleaner in proper condition
is very important. Dirt induced through im-
properly installed, improperly serviced or in-
adequateelements, wears out engines. Keep
the elementalways clean.
(a) Unlock the cover and removethe cleaner
element.
(b) Inner element:Wash the element with
kerosene,then soak
it in mixed oil (Kero-
sene
(3): Engineoil (1)).
Drainthe mixedoil.
(c) Outer element:Wash the element with
kerosene, then dip it into the mixed oil
(Kerosene
(3): Engineoil (1)).
Squeezeoutthe mixedoil. (Do nottwist.)

WHEN ENGINEDOES NOTSTART:
fore you take the pump to your
Makitadealer.
If you still have trouble after com-
pleting the checks, take the pump
to your nearest Makitadealer.
Before testing, carefully wipe off
spilled fuel.
Put the plug as far away from the
spark
plug holeas possible.
Ground the side of the electrode to
any engine ground.
bl
A-
1. Removethe plug and connect itto the plug cap.
Pull the starter handle while putting the plug
againstthe engine ground.
2. Try with a new plug if the spark is weak or no
spark flies.
3. The ignition system is faulty if there is no spark
with a new plug.
Take your pump to 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 different fuel.

Remove the strainer cup, and open the strainer cock to discharge the fuel
from the fueltank.
Remove the carburetor float chamber boltfrom the bottom and discharge fuel
from the carburetor.
(NO SMOKING !)
Changethe used engine oilwith fresh oil.
Remove the spark plug, pour about 5 cc of engine oil into the cylinder, slowly
pull the starter knob of the recoil starter
2 or 3 times, and tighten the spark
Plug.
Slowly pull the recoil starter knob until resistance is felt and leave it in that

11 OIL SENSOR INSTRUCTIONS
OIL SENSOR (OPTION)
(a)The oil sensor detects thefall in oil levelin
the crankcase and automatically stops the
engine when the
oil levelfalls down below
the predetermined level.
(b) When engine has stopped automatically,
check the
oil level. Refill engine oil to the
upper leveland restartthe engine.
(c) If the engine does not start by usual
startingprocedures, check the
oil level.
when refilling with oil. Remove oil
filler cap on the opposite side of
carburetor.
