- A clear or fresh water centrifugal pump set powered with a Robin Subaru gasoline
engine delivering 45 M3/h.
- The inlet and outlet ports are of a diameter of 2“ BSP, delivered with couplings and
strainer.
2. 2. SAFETY INSTRUCTIONS
Make sure that you review each warning and respect all safety recommendations.
2-1. ENVIRONMENT
Use your pump set on a flat, stable base, free from gravel or grit.
Install your pump set at least 1 meter from any building.
Install your pump set far away from any inflammable product (waste materiel, lubrication
liquid, explosive, …)
IN THE CASE OF FREEZING WEATHER CONDITIONS, MAKE SURE TO EMPTY
THE PUMP CASING TO AVOID BEING FROZEN AND DAMAGING THE PUMP.
2-2. FIRE PROTECTION
Stop the engine before filling the fuel tank.
Do not overfill the fuel tank and spill gasoline.
If the gasoline spills over, rapidly clean up the spilt gasoline and wait
for the traces to be dried up before restarting the engine.
Never use the pump set while smoking or near a naked flame.
2-3. EXHAUST GAS PROTECTION
Never breath in the exhaust gas: it contains carbon monoxide which
is odour and colourless and extremely dangerous for human health.
In extreme conditions it can be fatal.
Never use your pump set inside a building or in a closed environment.
Be extremely careful when using the pump set close to other people.

pump when it’s running.
Never let someone run the pump set without proper understanding
of the manual and safety instructions.
Start by familiarising yourself with emergency stopping procedure
as well as all aspects of safety controls to be made on the pump set

4. PREPARING THE PUMP FOR OPERATION
4-1. CONNECT THE SUCTION PIPE TO THE PUMP
Use the appropriate tools to make the connection.
If the pump set is pumping water containing solids, ii is
necessary to use a strainer connected to the suction pipe.
These foreign bodies can damage the pump if they are sucked
into the pump casing.
4-2. CONNECTER THE DELIVERY HOSE TO THE PUMP
Use the appropriate tools to make the connection.
4-3. CHECK THE ENGINE OIL LEVEL
Place the pump set on a horizontal flat surface and fill the engine sump until you achieve
the maximum level on the dipstick (approximately 0,6 litre).
- Use an engine oil with a viscosity de 10 W 30 for ambient temperature between -15°C
to + 35°C
- If the conditions of use should exceed these limits, please contact WORMS
ENTREPRISES concerning the correct type of oil to use.
- Oil of an inferior quality or a lack of oil can cause serious engine damage and reduce
the expected engine life time.
Use only engine oil designed for petrol engines.
Never use engine oil designed for diesel engines.
To check the correct oil level, simply position the dipstick in the
tapped hole without screwing it into position.
4-4. FILLING THE ENGINE FUEL TANK
- Use unleaded automotive gasoline.
- The fuel should be new and free for foreign particles. The fuel should be transported
in containers designed for unleaded automotive gasoline. If this is not the case, the
8
carburettor could become faulty, blocked with foreign bodies.
- The tank contains 3,6 litres.
- Wipe off any spilt fuel thoroughly.
- Always stop the engine before refilling the fuel tank.
4-5. FILLING THE PUMP BODY WITH WATER
Fill the pump body with water through the fill plug located on the top of the casing, before
starting the engine.
Do not run the pump dry; always fill the pump body with water
before staring. Failing to do this will cause the pump to overheat.
Using the pump dry will destroy the mechanical shaft seal. If the
pump should run dry, the pump must be left to cool before filling
with water in order to avoid a thermal shock which will damage
the pump.

position. Pull the recoil starter gently, when the effort increase due to the compression,
bring the recoil handle to its original position. Then pull the recoil starter swiftly to start
the engine, once the engine starts, return the handle slowly to its original position.
5-2. COLD STARTING

5-3. RUNNING SPEED
Once the engine started, open progressively the choke, place the engine speed control
