3. The suction strainer MUST be attached to the end of suction hose, to prevent
large stones etc., from being drawn up which could cause severe damage.
Keep the strainer clean. If it is likely to clog with dirt or debris, proceed as
follows:
a. Prepare a bed of stones on which to rest the strainer.
or b. Tie the strainer so that it stays off the bottom of the pit, pond or excavation.
or c. Tie the strainer inside a basket or bucket.
4. Remove the Filler Plug on top of the pump case and fill the pump with water,
leaving no air gap. Remember the pump is self-priming only when the pump
is filled. It will prime and reprime itself without refilling. Refilling is necessary only
if the pump has been drained or if the water has been lost. Never run the
pump dry.
5. Ensuring there is adequate drainage for the discharged water, attach the
discharge hose if required, ensuring it is well protected and supported.
If the discharge line runs vertically more than 30ft., it is advisable to install a
check valve in the discharge line near the pump to stop destructive liquid
hammer when the pump is shut down. If a check valve is installed, it may also
be necessary to vent the top of the pump so that air can he expelled during
automatic repriming. This air bleed may he accomplished by providing a 1/4"
line from the top of the pump back to the liquid source. We will not assume
any responsibility for damage to the pump if no check valve is used in the
discharge line.
Properly fuelled and lubricated, your pump will run without attention.
OPERATION (Refer to the illustration on page 3)
Ensure the site and pump is prepared as detailed on page 4,then proceed as
follows:
1. STARTING.
Refer to the Engine Manual. Pay particular attention to “running in” the engine.
Do not exceed the recommended engine speeds or running duration.
1.1 With the fuel cock open, pull the starter recoil rope slowly two or three times,
to allow fuel to reach the carburettor.
1.2 Hold down the pump, and with the ignition switch ON, and choke and throttle,
set according to the engine manual, pull the starter recoil rope firmly until the
engine starts. Do not snatch at the starter rope, and allow it to retract slowly
after each pull.
1.3 Once the engine starts, set the choke according to the manual, and use the
engine throttle to gradually increase engine speed.
