1. Remove the priming cap (3) and ll the pump housing
with water before retting the cap and starting your
pump (Fig. 10).
This will allow the pump to create a low-pressure
vacuum that will draw the water up for pumping.
2. Fill the suction hose up with water.
Important: Ensure that the strain lter (F) is tted to
the suction hose and remains completely submerged
throughout the pumping operation.
Important: Once your pump is started, it may take
several minutes to complete priming. This time will
vary due to the length of the suction hose tted
(a longer suction hose will take longer to fully prime
and start pumping water).
Once the pump has fully primed, it will draw the water
from the water source and pump it out through the
pump's outlet and into any layat discharge hose that is
tted to direct the pumped water to the desired location.
9.2 Starting the Pump
Important: Read and understand all Health and Safety
guidance and preparation instructions before attempting
to operate the pump.
1. Slide the fuel lever (18) to the right to turn on the fuel
supply.
2. Slide the throttle lever (20) to the left to open the
throttle slightly.
3. Open or close the choke as appropriate (Fig. 11):
− When performing a cold start, keep the choke
closed (pushed to the right).
− When performing a warm start, open the choke
(pushed to the left) while starting the engine.

10.5 Spark Plug Care
Important: The spark plug should be checked and
cleaned after every 50 hours of use and replaced if
necessary.
1. Remove the spark plug cap (9) by hand (Fig. 18).
2. Pass the spark plug spanner handle (I) through the
holes in the spark plug spanner body (H) and use the
assembled spanner to remove the spark plug (Fig. 19).
3. Inspect and clean the spark plug:
a. The spark plug should be tan in colour.
b. Check the spark plug for cracks or chips in the
ceramic insulator.
c. Measure the gap using a feeler gauge (not
supplied) and correct it as appropriate by gently
bending the electrode into position.
Important: The gap should be 0.7–0.8mm.
d. Replace the spark plug if necessary.
4. Install the spark plug using 20Nm of torque.
10.6 Changing the Engine Oil
Important: The engine oil should be changed after the
rst 20 hours of operation and then every 100 hours
thereafter.
1. Unscrew and remove the dipstick (6), then the sump
bolt (7) and drain the oil into a suitable container.
(Fig. 20).
Important: ALWAYS dispose of oil in accordance
with local regulations.

10.8 Storing the Pump
Prepare the pump correctly if it is to be stored for a
prolonged period:
1. Ensure that all switches are in the OFF or lowest
position.
2. ALWAYS allow the pump to cool for at least
30 minutes when storing it after use.
3. Remove, drain and dry the suction and discharge
hoses and clean around the inlet and outlet openings.
Ensure all other water is also drained from the pump.
4. Drain the fuel from the engine before storage
(see 10.5 Draining the Fuel).
5. Drain the engine oil (see 10.3 Changing the
Engine Oil).
6. Cover the pump with a plastic sheet to protect it
against dust and moisture.
Observe the following points when storing the pump:
• Store the pump in a dry and dust-free environment,
out of reach of children.
• Store the pump in its operating position.
− NEVER store the pump on its side as this may
cause fuel or oil to leak and damage the pump or
the surrounding property.
− Where possible, secure the pump in its upright
position to prevent it from tipping over while
unattended.
• Prepare and run the engine at periodic intervals to
prevent seizure within the engine and driveshaft.
