PUMP SAFETY IMPORTANT SAFETY INFORMATION Honda WT20X, WT30X, and WT40X pumps are designed to pump only water that is not intended for human consumption, and other uses can result in injury to the operator or damage to the pump and other property. Most accidents can be prevented if you follow all instructions in this manual and on the pump. The most common hazards are discussed below, along with the best way to protect yourself and others.
PUMP SAFETY Hot Exhaust The muffler becomes very hot during operation and remains hot for a while after stopping the engine. Be careful not to touch the muffler while it is hot. Let the engine cool before transporting the pump or storing it indoors. To prevent fire hazards, keep the pump at least 3 feet (1 meter) away from building walls and other equipment during operation. Do not place flammable objects close to the engine.
PUMP SAFETY SAFETY LABEL LOCATIONS The labels shown here contain important safety information. Please read them carefully. These labels are considered permanent parts of your pump. If a label comes off or becomes hard to read, contact an authorized Honda servicing dealer for a replacement. \~ETERSO~AL PUMP CAUTION INJURY.

BEFORE OPERATION ARE YOU READY TO GET STARTED? Your safety is your responsibility. A little time spent in preparation significantly reduce your risk of injury. will Knowledge Read and understand how to operate them. this manual. Know what the controls Familiarize yourself with the pump and its operation pumping. Know what to do in case of emergencies. before you begin Be sure of what you are pumping. This pump is designed only water that is not intended for human consumption.
BEFORE OPERATION IS YOUR PUMP READY TO GO? For your safety, and to maximize the service life of your equipment, it is very important to take a few moments before you operate the pump to check its condition. Be sure to take care of any problem you find, or have your servicing dealer correct it, before you operate the pump. Improperly maintaining this pump, or failing to correct a problem before operation, could cause a malfunction in which you could be seriously injured.
BEFORE OPERATION Check the Suction and Discharge Hoses l l l l Check the general condition of the hoses. Be sure the hoses are in serviceable condition before connecting them to the pump. Remember that the suction hose must be reinforced construction to prevent hose collapse. Check that the sealing washer good condition (see page 17 ). in the suction Check that the hose connectors (see pages 17& 18). and clamps Check that the strainer is in good condition suction hose (see page 17 ).
OPERATION SAFE OPERATING PRECAUTIONS To safely realize the full potential of this pump, you need a complete understanding of its operation and a certain amount of practice with its controls. Before operating the pump for the first time, please review the IMPORTANT SAFETY INFORMATION on page 5 and the chapter titled BEFORE OPERA TION. For your safety, avoid starting or operating the engine in an enclosed area, such as a garage.
OPERATION PUMP PLACEMENT For best pump performance, place the pump near the water level, and use hoses that are no longer than necessary. That will enable the pump to produce the greatest output with the least self-priming time. As head (pumping height) increases, pump output decreases. Maximum head specifications and pump performance curves are shown in the tables on pages 57,59 and 61 . The length, type, and size of the suction and discharge hoses can also significantly affect pump output.
OPERATION SUCTION HOSE INSTALLATION Use the commercially available hose and hose connector with the hose clamp provided with the pump. The suction hose must be reinforced with a noncollapsible wall or braided wire construction. The suction hose should be no longer than necessary. Pump performance is best when the pump is near the water level, and the hoses are short. Use a hose clamp to securely fasten the hose connector hose in order to prevent air leakage and loss of suction.
OPERATION DISCHARGE HOSE INSTALLATION HOSE CONNECTOR Use a commercially available hose with the hose connector and clamp provided with the pump. It is best to use a short, largediameter hose, because that will reduce fluid friction and improve pump performance. A long or small-diameter hose will increase fluid friction and reduce pump output. Tighten the hose clamp securely to prevent the discharge hose from disconnecting under high pressure.
