3 OPERATING INSTRUCTIONS 1. Check filter screen to make sure it is clean. 2. Fill sprayer - 50 gallons maximum. 3. The pressure regulator valve (black knob) should be turned counter clockwise for zero pressure. 4. Turn input valve at control block to the ON position, parallel to piping. 5. Start the engine. 6. To control pressure (black knob), turn clockwise for high pressure, and counter clockwise for low pressure. 7. Turn valve to jet agitator to set the amount of agitation required. 8. If doing handgun work, connect hose to ON-OFF valve and turn valve handle to the ON position. Then control spray and pattern with handgun. 9. If doing spray boom work, connect the two hoses from the boom to the two ON-OFF valves and turn valve handles to the ON position. CLEANING & STORAGE 1. Wash and flush out sprayer after completion of each phase of your spraying program. Never leave chemicals in the tank. 2. Flush out sprayer when changing chemicals if there is a possibility of incompatibility. 3. Clean sprayer very thoroughly before storing at the end of spraying season. If you are in a cold climate, final rinse should be with a sufficiently concentrated anti-freeze, to prevent freeze-up in areas that were not thoroughly drained. 4. Check sprayer for possible need of repairs before using sprayer again. 5. Never leave the sprayer in the sun for long periods of time. Page 1

4 GENERAL SAFETY INFORMATION Use of pressure relief device on the discharge side of pump is required to prevent damage from pressure build-up if the discharge is closed or blocked while the power source is still running. WARNING: DO NOT PUMP FLAMMABLE OR EXPLOSIVE FLUIDS, SUCH AS GASOLINE, FUEL OIL, KEROSENE, ETC. DO NOT USE IN EXPLOSIVE ATMOSPHERES. THE PUMP SHOULD BE USED ONLY WITH LIQUIDS COMPATIBLE WITH THE PUMP COMPONENT MATERIALS. FAILURE TO FOLLOW THIS WARNING CAN RESULT IN PERSONAL INJURY AND/OR PROPERTY DAMAGE AND WILL VOID THE PRODUCT WARRANTY. Do not operate pump above recommended R.P.M. Do not pump at pressure higher than the maximum recommended for the pump (See Specifications). Operate pump between 45 o and 145 o F liquid temperatures. Make certain that the power source conforms to the requirements of your equipment. Provide adequate protection in guarding around the moving parts, such as the shaft and pulleys. Disconnect power before servicing. Release all pressure within the system before servicing any component. Drain all liquids from the system before servicing. Secure the discharge lines before starting the pump. An unsecured discharge line may whip, causing personal injury and/or property damage. Check hoses for weak or worn condition before each use. Make certain that all connections are tight and secure. Periodically inspect the pump and the system components. Perform routine maintenance as required (See Maintenance Section). Do not operate a gasoline engine in an enclosed area. Be sure the area is well ventilated. Use only pipe, hose and fittings rated for maximum rated pressure of pump or pressure at which pressure relief valve is set. Check with local supplier for proper pressure rating. Do not use used pipe! Do not use these pumps for pumping water or other liquids for human or animal consumption. Page 2

5 PUMP MAINTENANCE The pump is serviced, tested and ready for use. Never the less, before starting the pump we advise checking the oil level. The oil level should be filled to the mark on the plastic tube. When adding oil, remove oil filler cap and fill to level mark with SAE 30 weight engine oil. The pressure accumulator is an important part of the pump as it prevents pulsation. Therefore, it is necessary to make sure the accumulator pressure is approximately 10% of pump working pressure. To check pressure or add air, remove cap. After use, flush pump with clean water. Change oil and diaphragms every 500 hours. To drain oil from the pump, remove drain plug and rotate the shaft until the oil stops flowing out. To fill pump with oil, slowly pour oil into sight tube while turning the pump shaft. Turning the pump shaft purges all the air out of the crankcase. Always change oil when replacing diaphragms. For winter storage or if a freezing condition will be encountered, flush pump with a 50/50 mixture of water and anti-freeze. Page 3

6 DIAPHRAGM & VALVE REPLACEMENT I. Valve and o-ring replacement 1. Occasionally debris can cause the valves to not seat properly or damage the o-rings. To check for this problem: A. Remove manifold on pump head assembly. Use a 17mm box wrench to remove manifold nuts. B. With manifold removed, valves can readily be removed and checked for debris or wear. C. To replace valves or o-rings, refer to parts list for appropriate kits. II. Diaphragm replacement 1. Drain the oil from the pump by removing drain plug. Rotate the shaft to remove excess oil. 2. Remove the pump manifold according to Step A in Section I. 3. Use a 13mm box wrench to remove the diaphragm retaining bolt, support washer and diaphragm. A. To replace diaphragms order appropriate repair kit. (See Parts List) 4. Turn the crankshaft to bring the piston to its downstroke and seat the new diaphragm into the sleeve groove. Install retaining washer and tighten nut. 5. Replace the pulsation damper diaphragm by first bleeding the air from the damper. (See Parts List for your model). Use a 13mm box wrench to remove the bolts holding the damper assembly together, then replace diaphragm. Recharge damper to 10% of operation pressure. 6. Refill crankcase with 30 weight engine oil. Rotate the shaft to distribute oil and fill to proper level. Page 4

7 TROUBLESHOOTING PROBLEM CAUSE SOLUTION One or more valves are seating improperly. The pump does not draw water Suction line is plugged or collapsed - Clogged strainer. Examine the valve seatings and clean them. Examine suction line - clean strainer. Pressure gauge fluctuates excessively The liquid flow is irregular Output drops and the pump is noisy Oil comes out of the discharge port Water is pumped at little or no pressure The pump is sucking in air through the suction union or air has not been entirely evacuated from the pump. One or more valves are seating improperly. Oil level is too low. One or more diaphragms split. The sealing valve on the pressure control valve is worn. Examine the suction hose and make sure it is firmly secured. Run the pump with the outlet hose open to evacuate air from pump. Examine the valve seatings and clean them. Add oil to correct level (halfway up the sight tube). Drain the pump of oil. Dismantle the heads and fit new diaphragms. Fill to correct oil level with Motor oil (30W). Renew washer and, if necessary, the valve seat. Page 5
