( I ) SAFETY INFORNATIONS
•To sure safety, don' t use water pump pump combustible,
caustic, brine(e.g, wine, boney, oil has been used), or
caustic liquid(e.g, gasoline and acid).
•To prevent fire, stop engine when refueling.
•To prevent fire, clean tt_e overflowing fuel.
•To prevent fire, never use the machine in flammable
conditions.
•place the machine in a place where pedestrians or
children are not likely to touch the machine.
•To prevent being poisoned and fire disease, when
exhausting, never point to building or appliance with
exhaust pipe.
•To prevent being poisoned, never operate the machine
indoors or any where witt_ air blocked.
•To avoid accident, please place tt_e water pump in tt_e
horizontal and solid position.
•To avoid accident, before you start the engine, please
check tt_e machine is safety.
•Before starting, please check tt_e oil is full.
(II) SAFETY LABEL LOCATIONS

(IV) PRE-STARTING OPERATION
1: Connect intake pipe
Used conmlercially available bose, pipe joint and pipe
connecting hoop. The intake pipe must be continuous and
can not be folded exceed what' s needed, the pump does
best when it is not far from the water. The time that
the pump takes water is in direct proportion to the
length of the intake pipe. The filter which forms
complete set with the pump must be fixed on the end the
intake pipe as shown in the picture.
QBefore pumping water, the filter must be fired on the
end of the intake pipe. The filter can help remove the
mess which may result in blocking and can harm the
impeller.
Caution: Fix the pipe joint and pipe connecting hoop
well, in case it leaks air and lower the intake power.
If the intake pipe is uncrowned, it will do harm to the
function of the pump and it will weaken the taking water
ability of the pump.

2: Connect outlet pipe
[se conmlercially available bose, pipe _joint and pipe
connecting hoop. i short pipe of by diameter does best,
long pipe of small diameter add to flowing resistance
and reduce the output rate of the pump.

3: Check oil lever
Caut ion:

SEngine oil is one of the main factors which influence
the function and the using life of the generator. Do not
recommend to use dirty engine oil.
Qcheck the oil lever when the generator stops and make
sure theftthe generator in the horizontal position.

detergent, premium qut_litymotor oil certified to meet
or exceed [.S automobile mal_t_facturer's reqt_irements
for service classification SG, SF. Motor oil s classified
SG, SF will show this designation on the container.
Select the appropriate viscosity for the average
temperature in your area.
Caut ion:
Running the engine with low oil lever will cause serious
engine d_mlage.

4: Check tilefuel levelRemove
the fuel tank cap andcheck tile
fuel level.
If the fuel is low, please add
fuel.
Never use all oil gasoline
mixture or dirty gasoline.
Avoid getting dirt, dust or
water illtilefuel tank.
5: Check tile air cleaner elementsRemove tile screw,
cushion and air cleaner cover. Check tileair cleaner
element for dirt or obstruction,
clean the air cleaner element,
if it is dirty(see page 14) aircleancover
Caut ion:
Never run tileengine without tile
_ir cleaner.
6:Check whether tile pump is
filled with water
The pump must completely filled
with water before it runs.
Cauti on:
Do not try to run tilepump before filled it with water,
otherwise it will become too hot. The long time running
with no water of tilepump will harm. If there is no
water illthe pump, stop the generator immediatelyand
filled tilepump with water when it cools off.

C: Sock the element in clean engine oil and squeeze out
the excess oil.
D: Reinstall the air cleaner element and the air cleaner
cover.
3: Spark plug serve
Recommended spark plug: NHSP LD F6RTC[
To ensure proper engine operation, the spark plug must
be properly gapped m_d free of deposits.
A: Remove the spark plug cap.
Warning:
If the engine has been running, the muffler will be very
hot, be careful not to touch the muffler.
B: Visually inspect the spark plug. Discard it if there
is apparent wear or the insulator is <:racked or chipped.

Clean the spark plug with a wire brush if it is to be
reused.
O. 70-0. 80mm
O.028-0. 031in
C: Measure the plug gap with a feeler gauge.
Correct as necessary by carefully bending the side
electrode.
The gap should be O. 70 O. 80nml
D: Check that the spark plug washer is in good condition
and thread the spark plug in by hand to prevent cross
threading.
Note:
After a new spark plug has been seated by band, it should
be tighten 1/2 turn with a wrench to compress its washer.
If a used plug is being reinstalled, it should only
require 1/2 to 1/-'I turn after being seated.
Caut ion :
The spark plug must be securely tightened. An improperly
tightened plug can become very hot and possibly damage
the engine.

(X) TROUBLESHOOTING
Engine won't start
1:Is there fuel in the fuel tank?
2:Is the fuel valve in the "on" position?
