Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com BEFORE USE The pump is supplied with four rubber feet. Use the retaining nuts to secure these to the base of the frame. Stand the pump on a firm foundation as near to the water source as possible. Ensure there is adequate drainage for the discharged water and that there is no danger of damage to property as a result of water being discharged. ADDING OIL This pump is supplied without engine oil or fuel. Use any engine oil of SAE 15-40 rating unless operating at very high or low ambient temperatures. Fill the engine crankcase with oil as follows: 1. Remove the filler plug/dipstick. 2. Fill with oil until visible inside. 3. Check the level by inserting the dipstick back into the filler neck and checking the level is within the indicated range. If correct replace the dipstick/filler cap. NOTE: The pump is fitted with a low oil sensor which will stop the engine if the oil level drops below the safe level to avoid internal damage. Refer to troubleshooting section. ADDING FUEL
- Use unleaded petrol. 1. Open the fuel cap and top up as required. Located within the fuel tank is a filter. Check this filter periodically and remove any contaminants which may have accumulated. Do not fill above the fuel filter shoulder. 2. After refuelling, tighten the fuel filler cap securely. WARNING: WIPE UP ANY SPILT FUEL BEFORE RUNNING THE PUMP. ALLOW THE ENGINE TO COOL DOWN BEFORE REFUELLING
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com GENERAL USE OF THE PUMP 1. Connect the suction and discharge hoses to the pump housing using the hose clamps and gaskets supplied to achieve an airtight seal. There must be no damage of any kind to the hoses which must be well protected and supported. NOTE: Hoses or pipes should be supported independently and not have their weight carried by the pump. IMPORTANT: An air leak in the suction line will prevent priming, and reduce the capacity of the pump. 2. Pay particular attention to the following: Always ensure the hose adaptor gasket is in place and correctly fitted. Always use a flexible hose at the pu mp body connection of at least 1ft (300 mm). Keep all pipes/hoses as short and st raight as possible and avoid sharp bends. If a flexible hose must be laid across a roadway, protect it with planking. Ensure there is adequate drainage for the water being discharged. Instantaneous shut off pressure, applied when a vehicle runs across an unprotected hose, will cause “hydraulic shock”, which can damage the pump and/or the hose). 3. Attach the suction strainer to the end of suction hose using a further hose clamp 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 by either: Preparing a bed of stones on which to rest the strainer. Tying the strainer so that it stays off the bottom of the pit, pond or excavation. Tie the strainer inside a basket or bucket. 4. Remove the filler plug on top of th e pump case and prime the pump with water, leaving no air gap. Remember the pump is self-priming only when the pump is filled. It will prime and re-prime itself without refilling. Refilling is necessary only if the pump has been drained or if the water has been lost. Never allow the pump to run dry. 5. 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 water hammer when the pump is shut down. If a check valve is installed, it may
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com also be necessary to vent the top of the pump so that air can be expelled during automatic re-priming. Properly fuelled and lubricated your pump will run without further attention. OPERATION Ensure the site and pump are prepared as detailed on page 6, then proceed as follows: PRIMING & CONTROL 1. Open the fuel shut-off valve and pull th e starter recoil rope slowly two or three times to allow fuel to reach the carburettor. 2. To start a cold engine, set the choke lever to the closed position, but if the engine is already warm the choke should be in the open position. 3. Set the throttle about one third open and turn the engine switch to ON. 4. 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. 5. Once the engine starts to warm up, gradually return the choke to the open position and use the engine throttle to gradually increase engine speed. STARTING After starting the engine, control the output by adjusting the engine speed. NOTE: With a suction lift of 5 to 10ft, the pump should begin discharging liquid in less than a minute. A lift of 25ft (at sea level) should require not more than 2 minutes for initial prime. To further reduce priming time the engine speed may be increased, after the engine is properly run in. If pumping does not start within this time, shut off the engine and check carefully to find the problem. (See TROUBLESHOOTING on page 10). NOTE: Filling the suction pipe with water will speed up the priming process, and it is recommended that a non-return valve be fitted to the end of the suction pipe. On higher vertical lifts, a higher engine speed is necessary but on shallow lifts or when there is little water to pump, preserve fuel and engine wear by reducing engine speed. WARNING: WHEN THE ENGINE IS RUNNING THE EXHAUST MUFFLER IS VERY HOT. TAKE CARE TO AVOID BURNS. NEVER RUN THE ENGINE IN AN ENCLOSED SPACE - ENSURE THERE IS ADEQUATE VENTILATION.
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com In the event of blockages, where debris has entered the suction chamber, this can be opened and cleaned out by removing the bolts (9) shown in the layout on page 4. SHUTTING DOWN 1. Gradually reduce engine speed to minimum using the throttle lever. 2. Stop the engine by switch ing OFF the ignition switch. 3. Close the fuel valve. MAINTANENCE 1. Always maintain the pump in a clean condition, checking regularly for loose bolts etc. 2. Clean the air filter once every 50 hours of use (or more often in unusually dusty conditions) as follows. Clean the foam filter element with domestic detergents and clean the mesh element by knocking against a solid object or blow out any dust with a high pressure air jet. Never operate the pump without the air cleaner installed as this would cause premature wear to the engine. 3. Replace the spark plug after the first month or every 50 hours of use. Check when installing that the spark plug has the correct clearance by measuring with a feeler gauge and adjusting the side electrode as required. Clearance should be 0.70- 0.80mm. The recommended spark plug for the PW80A pump is LD F7RTC.
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com CHANGING THE OIL The oil in the engine should be changed after the first 20 hours use and thereafter every 6 months or 100 running hours. Remove the dipstick and drain plug and then drain the oil. Re-fill and check the level as described on page 5. ENVIRONMENTAL PROTECTION One of the most damaging sources of pollution is oil. Do not throw away used oil with domestic refuse or flush down a sink or drain. Collect old oil in a leak- proof container and take it to your local waste disposal site. STORAGE & HANDLING After use, drain the pump body whenever there is danger of freezing. If the pump has been used with contaminated or salty water it should be thoroughly flushed with clean water following use, both inside and out and drained before replacing the drain plug. Always transport the pump with the fuel cock turned off and keep the unit level to prevent any fuel from spilling. If the pump is not to be used for some time it should be flushed thoroughly with clean water and drained completely before storing in a clean dry environment. Additionally, it should be prepared as follows: 1. Drain the fuel tank and carburettor completely by opening the drain plug in the carburettor float chamber and draining all remaining fuel into a suitable container ensuring the fuel shut-off valve is open. 2. Remove the spark plug, and pour 2-3 teaspoons of light oil into the cylinder through the spark plug hole. 3. Pull the starter recoil rope slowly 2 or 3 times so that the oil is deposited on the cylinder walls and replace the spark plug. CAUTION: PROLONGED EXPOSURE TO USED OIL IS HARMFUL. ALWAYS WASH YOUR HANDS THOROUGHLY AFTER HANDLING USED OIL.
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com TROUBLESHOOTING Problem Cause Solution Engine fails to start Lack of fuel in the tank Fill the tank as necessary No fuel reaching the carburetor Fuel valve is closed. Engine switch is in the Off position Set the engine switch to the On position. Lack of spark at the spark plug. Check that the spark plug wire is securely attached to the plug head. With the switch in the ON position, hold the spark plug side electrode against the engine and pull the starter cord to observe the spark. If a spark is present but the engine still cannot start consult your dealer for help. Engine stops and will not restart. Lack of oil in engine causing ‘Low Oil Protection’ sensor to stop engine from running. Fill the oil sump as necessary (see page 5) Pump fails to prime Priming chamber not filled correctly. Fill priming chamber leaving no air gap. Air leaks through the suction line joints (damaged hose, broken hose clamps, broken / ill-fitting gasket). Carry out repairs as necessary. Check/repair connections as required. Blocked inlet hose. Clean strainer & ensure it is not submerged in mud or sediment etc. Ensure there are no kinks in the delivery hose. Engine speed too low. Increase engine speed. Damaged impeller. Renew the impeller after dismantling the pump. Air leaks through damaged seal. Renew seal.
