Suction hose installation
To install your suction hose (Fig. 12.6) to the
pump suction port (Fig. 12.1) use the seal (Fig.
12.2), the hose connector (Fig. 12.3), the hose
connector clamp (Fig. 12.4) and the hose clamp
(Fig. 12.5) as shown in Fig. 12. It is recommended
that you use a suction hose of diameter same
as the suction port to avoid loss of performan-
ce due to friction of the water with the inside
of the hose walls or flow disturbances. On the
other end of the suction hose (Fig. 13.3) install
the strainer (Fig. 13.1) using the hose clamp (Fig.
13.2) as shown in Fig. 13. The strainer will help
to prevent the pump from becoming clogged or
damaged by any debris contained in the water to
be pumped.
Discharge hose installation
To install your discharge hose (Fig. 14.3) to the
pump discharge port (Fig. 14.2) use the seal, the
hose connector, the hose connector clamp and
the hose clamp (Fig. 14.2) as shown in Fig. 14. It
is recommended that you use a discharge hose
of diameter same as the discharge port to avoid
loss of performance due to friction of the water
with the inside of the hose walls or flow distur-
bances. Tighten the hose clamp securely to pre-
vent discharge hose from disconnecting under
high pressure.
Priming the pump
The inside of the pump body must be filled with
clean water before starting the engine.
WARNING
The pump should never be operated dry in order
to avoid damage to the seals and rotating parts
of the pump due to high temperature and fric-
tion.
To prime the pump:
1. Remove the pump priming cap (Fig. 15.1).
2. Fill the pump with clean water (Fig. 15.2).
3. Reposition the pump priming cap and tighten
appropriately.
STARTING THE UNIT
Before starting the machine:
1. Make sure both the machine and you are on
stable ground.
2. Check that all the fasteners are secured in po-
sition.
3. Prepare suction and discharge hoses and
make sure they are correctly mounted.
4. Check that the air filter is clean and that the
air intake and exhaust are not clogged by any
foreign materials.
5. Fill with the required quantity of oil and fuel.
6. Prime the pump.
To start the machine:
1. Move the fuel valve lever (Fig. 16.1) to the
"ON" position.
2. Move the choke lever (Fig. 17.1) to the "CHO-
KE" position.
NOTE
This step applies only to cold starting of the engine.
When the engine is already warm or the environ-
ment temperature is high, the choke lever should
be at "RUN" position at all times.
3. Move the ON / OFF switch to the "ON" positi-
on (Fig. 18.1).
4. Move the throttle lever (Fig. 19.1) by 1/3 of the
way towards the "A" (high speed) position.
5. Grip firmly the handle of the machine with
your left hand and the starter grip (Fig. 20.2)
of the engine with your right hand. Pull the
starter grip until you feel resistance to enga-
ge the engine and then pull firmly to start the
engine.
WARNING
To avoid breaking the starter rope (Fig. 20.1), do not
pull the whole length of it or let it slide along the
edge of the cable guide hole. Release the starter
gradually, to avoid letting it fly back uncontrollably.
6. As the engine warms up, gradually move the
choke lever to the "RUN" position, if the engine
was cold started.
NOTE
For maximum performance and reliability, allow the
engine to warm up before operating at full load, run-
ning it for two to three minutes at idle speed.
7. After the engine warms up, move the throttle
lever to "A" (high speed) position for self-pri-
ming and check pump output.
OPERATING THE UNIT
Throttle lever
Output flow is controlled by adjusting the engine
speed by moving the throttle lever between "A"
(high speed) and "B" (low speed) positions. Increa-
sing the engine speed, increases the pump output
flow. Decreasing the engine speed, decreases the
pump output flow.
STOPPING THE UNIT
To stop the machine:
1. Lower the engine speed by moving the throttle
lever to the "B" (low speed) position.
2. Move the ON / OFF switch to the "OFF" position
(Fig. 18.2).
3. Move the fuel valve lever to the "OFF" position.
4. Remove the pump drain plug and drain the
pump body chamber dry.
5. Remove the pump priming cap and flush the
pump body chamber with clean water to remo-
ve any pumped water residue or foreign mate-
rial that could damage the pump.
6. Allow all water to drain from the pump body
chamber.
7. Reposition the pump priming cap and pump
drain plug in place and tighten appropriately.
MAINTENANCE AND CLEANING
WARNING
Never do maintenance or cleaning with the unit run-
ning. Always work on a cool unit. Before cleaning or
doing maintenance work, disconnect the spark plug
cap and read the relevant instructions. Always wear
proper clothing and protective gloves whenever
your hands are at risk.
