SAFETY INFORMATION Do not operate or service the equipment before reading the entire manual. Safety precautions should be followed at all times when operating this equipment. Failure to read and understand the safety messages and operating instructions could result in injury to yourself and others. Potential hazards associated with the operation of this equipment will be referenced with hazard symbols which may appear throughout this manual in conjunction with safety messages.
SAFETY INFORMATION GENERAL SAFETY CAUTION NEVER operate this equipment without proper protective clothing, shatterproof glasses, respiratory protection, hearing protection, steel-toed boots and other protective devices required by the job or city and state regulations. NEVER operate this equipment when not feeling well due to fatigue, illness or when under medication. NEVER operate this equipment under the influence of drugs or alcohol.
SAFETY INFORMATION CAUTION NEVER lubricate components or attempt service on a running machine. NEVER block or restrict flow from discharge hose. Remove kinks from discharge line before starting pump. Operation with a blocked discharge line can cause water inside pump to overheat. NOTICE ALWAYS fill the pump casing with water before starting the engine. Failure to maintain water inside the pump housing will cause severe damage to the pump and mechanical seal.
SAFETY INFORMATION Store fuel in appropriate containers, in well-ventilated areas and away from sparks and flames. NEVER use fuel as a cleaning agent. DO NOT smoke around or near the equipment. Fire or explosion could result from fuel vapors or if fuel is spilled on a hot engine. BATTERY SAFETY (ELECTRIC START ONLY) DANGER DO NOT drop the battery. There is a possibility that the battery will explode. DO NOT expose the battery to open flames, sparks, cigarettes, etc.
SAFETY INFORMATION ENVIRONMENTAL SAFETY/DECOMMISSIONING NOTICE EMISSIONS INFORMATION NOTICE Decommissioning is a controlled process used to safely retire a piece of equipment that is no longer serviceable. If the equipment poses an unacceptable and unrepairable safety risk due to wear or damage or is no longer cost effective to maintain (beyond life-cycle reliability) and is to be decommissioned (demolition and dismantlement),be sure to follow rules below.

GENERAL INFORMATION APPLICATION ground in a level position. The Multiquip QP3TH Trash Pump is designed to be used for dewatering applications. Both the suction and discharge ports on the QP3TH trash pump use a 3-inch diameter opening,which allows the pump to pump at a rate of approximately 396 gallons/minute (gpm) or 1,500 liters/ minute (lpm). NEVER place the pump on soft soil. The suction hose or pipe connection should always be checked for tightness and leaks.
PUMP COMPONENTS Figure 3 shows a typical application using the QP3TH centrifugal pump. Please note that this pump is intended for the removal of clean water. Figure 3. QP3TH Pump Application 1. Pump — The model QP3TH is a 3-inch trash pump aused in general dewatering applications.Typical dewatering applications consist of manholes, septic tanks, fast and slow seepage ditch water, silt water, mud water and muck water. 7. Suction Hose — Connect this flexible rubber hose to the suction port on the pump.
BASIC ENGINE Figure 4. Engine Controls and Components INITIAL SERVICING The engine (See Figure 4) must be checked for proper lubrication and filled with fuel prior to operation. Refer to the manufacturers engine manual for instructions and details of operation and servicing. The engine shown above is a HONDA engine, operation for other types of engines may vary somewhat. 1. Fuel Filler Cap — Remove this cap to add unleaded gasoline to the fuel tank. Make sure cap is tightened securely. DO NOT over fill.
INSPECTION (ENGINE) CAUTION DO NOT attempt to operate the pump untilthe Safety Information, General Information and Inspection sections of this manual have been read and thoroughly understood. 3. Insert and remove the dipstick without screwing it into the filler neck. Check the oil level shown on the dipstick. 4. If the oil level is low (See Figure 6), fill to the edge of the oil filler hole with the recommended oil type (Table 5). Maximum oil capacity is 1.16 quarts (1.1 liters).
SETUP 1. Place pump as near to water as possible, on a firm flat, level surface. 2. To prime pump, remove fill cap (See Figure 3) and fill pump casing with water. If the pump casing is not filled with water before starting, it will not begin pumping. 3. Attach suction and discharge hoses to the pump. Check that all hoses are securely attached to the pump. Make certain suction hose (See Figure 3) does not have any air leakage. Tighten hose clamps and couplings as required. 4.
OPERATION CAUTION DO NOT attempt to start the engine unless the pump has previously been primed with water. Severe pump damage will occur if pump has not been primed. 4. Place the choke lever (See Figure 10) in the OPEN position if starting a warm engine or the temperature is warm. STARTING THE ENGINE 1. Place the engine fuel valve lever (See Figure 7) to the ON position. Figure 10. Engine Choke Lever (Open) 5. Place the engine ON/OFF switch (See Figure 11) in the ON position. Figure 7.
OPERATION STOPPING THE ENGINE Normal Shutdown 1. Move the throttle lever to the IDLE position (See Figure 14) and run the engine for three minutes at low speed. Figure 13. Choke Lever (Open) 8. Before the pump is placed in to operation, run the engine for several minutes. Check for fuel leaks, and noises that would associate with a lose component. 9. To begin pumping, place the throttle lever (See Figure 13) in the RUN position.
MAINTENANCE (PUMP) PUMP VACUUM TEST CAUTION DO NOT attempt to start the engine unless the pump has previously been primed with water. Severe pump damage will occur if pump has not been primed. To perform the pump vacuum test do the following: 1. Remove the pump fill cap (See Figure 3), and fill the pump with water. 2. Start the engine as outlined in the initial start-up section, and wait for the pump to begin pumping. 3.

MAINTENANCE (ENGINE) ENGINE MAINTENANCE Perform engine maintenance procedures as referenced by Table 6 below: Description (3) Engine Oil Air Cleaner All Nuts and Bolts Spark Plug Cooling Fins Spark Arrester Fuel Tank Fuel Filter Idle Speed Valve Clearance Fuel lines Operation Table 6.
MAINTENANCE (ENGINE) DAILY DANGER 1. Thoroughly remove dirt and oil from the engine and control area. Clean or replace the air cleaner elements as necessary. Check and retighten all fasteners as necessary. Check the spring box and bellows for oil leaks. Repair or replace as needed. WEEKLY 1. Remove the fuel filter cap and clean the inside of the fuel tank. 2. Remove or clean the filter at the bottom of the tank. 3. Remove and clean the spark plug (See Figure 19), then adjust the spark gap to 0.028~0.
MAINTENANCE (ENGINE) SPARK ARRESTER CLEANING Clean the spark arrester every 6 months or 100 hours. 1. Remove the 4 mm screw (3) from the exhaust deflector, then remove the deflector. See Figure 22. 4. Carefully remove carbon deposits from the spark arrester screen (Figure 23) with a wire brush. WIRE BRUSH 2. Remove the 5 mm screw (4) from the muffler protector, then remove the muffler protector. 3.
STORAGE PUMP STORAGE For storage of the pump for over 30 days, the following is required: Drain the fuel tank completely. Run the engine until the fuel is completely consumed. Completely drain used oil from the engine crankcase and fill with fresh clean oil, then follow the procedures described in the engine manual for engine storage. Remove the drain plug from the pump and drain out any water from left in the housing. Remove the pump cover and clean inside of pump housing.
TROUBLESHOOTING (ENGINE) Symptom Table 7. Engine Troubleshooting Possible Problem Solution Difficult to start Ignition plug being bridge? Fuel is available but spark plug will not Carbon deposit at ignition? ignite. (Power available at high tension Short circuit due to defective insulators? cable). Improper spark gap? Fuel is available but spark plug will not Short circuit at stop switch? ignite. (Power NOT available at high tension cable).
TROUBLESHOOTING (ENGINE/PUMP) Table 7. Engine Troubleshooting Possible Problem Symptom Operation not satisfactory Rotational speed fluctuates. Recoil starter not working properly. Symptom Governor adjustment improper? Governor spring defective? Fuel flow erratic? Air taken in through suction line? Dust in rotating part? Spring failure? Table 8.
