PREVENTING FIRES
Never add fuel to the fuel tank while the
engine is running. Wipe away all fuel spills
with a clean cloth. Keep gasoline, kerosene,
matches,otherexplosivesandammable
away from the product, since the tempera-
turearoundtheexhaustmuferisveryhigh
during operation.
·Topreventrehazardsandtoprovide
adequate ventilation, keep the pump at
least 1 m (3 ft) away from the building and
other equipment during operation.
·Operatethepumponaat,level,andrm
surface. If the pump is tilted, fuel spillage
may result.
PREVENTINGEXHAUSTGAS 
INHALATION
· Exhaust gas contains poisonous carbon
monoxide.
· Never use the pump in poorly ventilated
locations such as indoors or inside tun-
nels. If indoor operation is unavoidable,
provide proper ventilation so that people
and live stock will not be affected.
PREVENTINGBURNS
·Nevertouchthemufer,mufercoveror
engine body while the engine is running
or hot.
OTHER SAFETY ITEMS
· As this product is heavy, you may be in-
jured if you drop it on your feet or hurt
your back when moving it, so use several
people to move it.
· Know how to stop the pump quickly and
understand how to deal with all of the con-
trols. Never permit anyone to operate the
pump without proper instructions.
· Always wear a helmet and safety shoes
(non-skid soles) and proper clothes.
·Donotoperateunderinuenceofalcohol.
· Keep children and pets away from the
pump when it is in operation.
· Keep away from rotating parts while the
pump is running.
· Work according to rules and regulations
of work area.
SAFETY PRECAUTIONS
WARNING

6
While the engine is still new, applications
of heavy loads may shorten the life of the
engine.Duringtherst20hours,followthe
break-in procedures.
1. Avoidoverloads
During break-in period, avoid applying
heavy loads before the engine is stabi-
lized.
2. Changeengineoilregularly
About one month or 20 hours after initial
starting and every 3 months or 100 hours
thereafter, change the engine oil while the
engine is still warm.
OTHER PRECAUTIONS
NOTICE
· Be sure to drain the oil while the engineis
warm,otherwiseitmaybedifcultto
drain the oil completely.

7
1. Selectionoffueloil
Use the most suitable diesel fuel oil for
the engine.
2. Keepdustandwateroutofthefuel
Whenllingthefueltankfromdrums,
make sure no dust or water are mixed in
with the fuel since this may lead to serious
fuel injection pump and nozzle problems.
After 3–4 days : Put a
suction piple halfway
into the drum
(Water and dust ac-
cumulate in the lower
portion of the drum)
3. Donotoverll
Overllingisdangerous.Withtheengine
level,donotllthetankbeyondthetop
of the indicating ring (red) inside the fuel
tanklter.
CAUTION
Onlyusetherecommendeddieselfuel
oil.
Use of non-recommended fuel may cause
clogging in the fuel oil strainer, fuel injection
pump and fuel injection nozzle. This clog-
ging often causes sudden engine stops just
after starting.
ThefuelshouldhaveaCetanevalueof
morethan45inordertopreventdifcult
starting,misringandwhiteexhaust
smoke.
Dieselfueloilsubstitutesarenotrec-
ommended;theymaybeharmfultofuel
systemcomponents.
Thefuelshouldbefreeofwaterand
dust,becausethesecancausetrouble
inthefuelinjectionpumpandnozzle.
After purchasing
fuel: Allow drum to
stand 3–4 days
The fuel gauge displays how much fuel is
remaining. When the fuel tank is full, the
red indication is at "F" and gets closer to
"E" as fuel is consumed. When the red in-
dication bar gets to "E", refuel the engine
as soon as possible.

NOTICE
· The display is only a guide. Always
check the fuel limit position on the indi-

Donotsmokeorallowamesorsparks
intheareawheretheengineisrefueled
orwherefuelisstored.
Donotoverllthetankandmakesure
thellercapissecurelyclosedafterre-
fueling.
Becarefulnottospillfuelwhenrefue-
ling.Ifanyfuelisspilled,makesurethe
areaisdrybeforestartingtheengine.
Useproperengineoil.
If inferior oil is used, or if the engine oil is not
changed regularly, the risks of piston sei-
zure, piston ring sticking, accelerated wear
of the cylinder liner, bearings and other mov-
ingcomponentsincreasessignicantly.The
pump's life may be seriously shortened. We
recommend CD or Higher oil of API grade
classication.
Always use oil with the right viscosity for the
ambient temperature in which the engine is
being operated. Use the chart below when
choosing the engine oil.

Beforecheckingtheoillevel,makesure
thepumpissittinglevel.
If it is tilted, you may add either too much or
toolittleoil.Consequently,youmayoverll
and the engine will consume too much oil
and the oil temperature will become dan-
gerously high: or you may not add enough
oil, and the engine could seize up. Faults
caused by engine seizure are not covered
by the warranty.
Whencheckingtheoil,simplydipthe
dipstickintotheoilpan.Donotscrewin

If you install coupling packing not inabove
order, air leakage may result, affecting water

1. Fixthestrainerattheendofthesuc-
tionsidehoseandtightenitwiththe
hoseband.Thenplaceitinthewater.
Make sure suction hose is connected
properly. In case of no self-priming after
llingpumpwithwaterandengineisstart-
ed, check suction hose connection care-
fully again. Most cases of no self-priming
are caused by improper hose connection.
· Use suction hose for suction side.
· Do not change pump diameter by alter-
ing suction hose.
2. Fixthesuctionsidehosetothesuction
portofthepumpandtightenitwitha
band.
3. Fixthedischargeportsidehosetothe

4. Fixtheendofthehosetotheplace
wherewaterisrequired.
Ensure no obstacle is at discharge hose
side.
Donotblock,kink,orobstructtheowof
liquid through the discharge hose.
5. Fillthewaterpumpwithwater.(This
wateriscalled"primingwater".)Re-

NOTICE
· Pump failure will occur if the suction
strainerisnotproperlytted.
The strainer keeps the size of the
suspended solids entering the pump
to the predetermined size the pump has
been designed to handle.
· The strainer should be installed in the
position where water accumulates most
easily. When installing on soft ground,
such as gravel or sand, position wooden
boards or blocks, etc. below the strainer
to prevent it from sinking into the ground.
Alternatively, suspend the hose avoiding
the bottom.

1. Drainwaterafteruse
· After use, remove the drain plug at the
bottom and pour water from the suction
/dischargeportssothattheremaining
sand is forced out of the pump. If the
pump is used to transfer muddy water
over a long period of time, a large vol-
ume of sand will be piled up in the pump
casing,makingitdifculttoremovethe
front cover. Therefore, clean the inside
the pump periodically.
