PUMP SAFETY SAFETY LABEL LOCATIONS This chapter explains what you need to know to operate your diaphragm pump safely. The label shown here contains important safety information. Please read it carefully. This label is considered a permanent part of your pump. So if the label comes off or becomes hard to read, contact your authorized Honda pump dealer for a replacement. IMPORTANT SAFETY INFORMATION The Honda WDP30X pump is not designed to pump drinking water.

CONTROL LOCATIONS GEAR BOX OIL FILLER CAP/DIPSTICK (p. 12) BEFORE OPERATION Your safety is your responsibility. A little time spent in preparation will significantly reduce your risk of injury. GEAR BOX DRAIN BOLT (Remove connecting rod cover) (p. 12) MUFFLER FUEL CAP AIR CUSHION CHAMBER CAP (Priming filler cap) (p. 5) Read and understand this manual.

OPERATION SAFE OPERATING PRECAUTIONS Before operating the pump for the first time, please review IMPORTANT SAFETY INFORMATION (page 2) and BEFORE OPERATION (page 3). For your safety, avoid starting or operating the engine in an enclosed area, such as a garage. Your engine’s exhaust contains poisonous carbon monoxide gas, which can collect rapidly in an enclosed area and cause illness or death. NOTICE Due to pump movement during operation, connecting a rigid pipe to the pump will cause pump damage.
PAGE 5
PUMP PREPARATION Pump Priming Optional hose kits, designed specifically for this pump, are available from your Honda dealer. See page 20. Pump priming is not required if the vertical distance from water to the pump (suction head) is less than 16 feet. The suction head can be increased to 24 feet if the pump is primed. Suction Hose Connection To prime the pump, remove the air cushion chamber cap. Grasp the suction hose next to the suction fitting and lift the hose about 1 foot off the ground.
PAGE 6
STARTING THE ENGINE 5. Pull the starter grip lightly until resistance is felt, then pull it briskly. 1. Turn the fuel valve to the ON position. FUEL VALVE NOTICE Return the starter grip slowly back to the engine to prevent damage to the starter. ON 6. As the engine warms up, gradually move the choke lever to the OPEN position. ……ON STARTER GRIP CHOKE LEVER 2. Move the choke lever to the CLOSED position. Do not use the choke if the engine is warm or the ambient temperature is high.

SERVICING YOUR PUMP Proper maintenance is essential for safe, economical, and trouble-free operation. It will also help reduce air pollution.  WARNING Improper maintenance, or failure to correct a problem before operation, can cause a malfunction in which you can be seriously hurt or killed. Always follow the inspection and maintenance recommendations and schedules in this owner’s manual.

ENGINE MAINTENANCE 2. Reinstall the drain bolt and sealing washer. Tighten the bolt securely. Engine Oil Level Check Check the engine oil level with the engine stopped and in a level position. 1. Remove the filler cap/dipstick and wipe it clean. NOTICE Improper disposal of engine oil can be harmful to the environment. If you change your own oil, please dispose of the used oil properly. Put it in a sealed container, and take it to a recycling center.
PAGE 9
Air Filter Inspection Air Filter Cleaning 1. Unscrew the outer wing nut and remove the air cleaner cover. A properly maintained air filter will help prevent dirt from entering your engine. Dirt entering the carburetor can be drawn into small passages in the carburetor and cause premature engine wear. These small passages can become blocked, causing starting or running problems. Always use an air filter specified for your engine to ensure it seals and performs as designed.

Spark Plug Service Spark Arrester (optional equipment) Recommended Spark Plug: NGK - BPR6ES Your pump engine is not factory-equipped with a spark arrester. In some areas, it is illegal to operate an engine without a spark arrester. Check local laws and regulations. An optional USDA approved spark arrester is available from an authorized Honda servicing dealer. See page 20 for part numbers. NOTICE Incorrect spark plugs can cause engine damage.

REFUELING Sediment Cup Cleaning 1. Turn the fuel valve to the OFF position. FUEL VALVE 2. Remove the sediment cup and O-ring and wash them in nonflammable solvent. Dry them thoroughly. This engine is certified to operate on unleaded gasoline with a pump octane rating of 86 or higher. OFF ON We recommend refueling after each use to minimize the air present in the fuel tank. Refuel in a well-ventilated area with the engine stopped. If the engine has been running, allow it to cool first.
PAGE 12
PUMP MAINTENANCE Pump Gear Box Oil Change Pump Chamber Flushing 1. Run the engine for 10 minutes to warm up the gear box oil. Warm oil drains quickly and completely. With the engine stopped, the pump case should be flushed after each use to prevent sediment from building up in the case. 2. Shut off the engine. 1. Disconnect the suction and discharge hoses. 3. Remove the two 8 x 15 mm bolts and washers from the connecting rod cover and remove the cover. 2.
PAGE 13
Pump Clappet Valves 2. Turn the fuel valve lever to the OFF position (page 3). 11. After tightening the nuts, insert a screwdriver into each port and check clappet valve operation. Clappets should operate freely and should seal when released. If a clappet does not operate properly, reinstall the clappet and recheck. 3. Flush the pump chamber (page 12). 12. Run the pump and check for leaks. 4. Lift the suction side of the pump and allow all the water to drain out the discharge fitting.

TRANSPORTING STORAGE BEFORE LOADING STORAGE PREPARATION When transporting the pump, be sure to keep it upright. If the pump is tilted or overturned, fuel may spill from the tank, which can result in a fire hazard. The following steps will help to keep rust and corrosion from impairing your pump's function and appearance, and will make the engine easier to start when you use the pump again. Allow the engine to cool before transporting the pump. Cleaning the Engine 1.

EMISSION CONTROL SYSTEM Source of Emissions The combustion process produces carbon monoxide, oxides of nitrogen, and hydrocarbons. Control of hydrocarbons and oxides of nitrogen is very important because, under certain conditions, they react to form photochemical smog when subjected to sunlight. Carbon monoxide does not react in the same way, but it is toxic.
