12/01/16 12:27:13 31YG0610_012 BEFORE OPERATION ARE YOU READY TO GET STARTED? Your safety is your responsibility. A little time spent in preparation will significantly reduce your risk of injury. Knowledge Read and understand this manual. Know what the controls do and how to operate them. Familiarize yourself with the pump and its operation before you begin pumping. Know what to do in case of emergencies. Be sure of what you are pumping.
12/01/16 12:27:22 31YG0610_013 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.
12/01/16 12:27:33 31YG0610_014 BEFORE OPERATION Check the Suction and Discharge Hoses 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 in the suction hose connector is in good condition (see page 16 ). Check that the hose connectors and clamps are securely installed (see pages 16 and 17 ).
12/01/16 14:01:53 31YG0610_015 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 OPERATION. For your safety, avoid starting or operating the engine in an enclosed area, such as a garage.
12/01/16 12:27:48 31YG0610_016 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. The length, type, and size of the suction and discharge hoses can also significantly affect pump output.
12/01/16 12:27:58 31YG0610_017 OPERATION SUCTION HOSE INSTALLATION Use a commercially available hose and hose connector with the hose clamp provided with the pump (if necessary). Most hoses come with the connectors already installed. The suction hose must be reinforced with a noncollapsible wall or braided wire construction and cannot contain any perforations. 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.
12/01/16 12:28:05 31YG0610_018 OPERATION DISCHARGE HOSE INSTALLATION Use a commercially available hose and hose connector and clamp provided with the pump (if necessary). It is best to use a short, large-diameter hose, because this will reduce fluid friction and improve pump performance. A long or smalldiameter hose will increase fluid friction and reduce pump output. Tighten the hose clamp securely to prevent the discharge hose from disconnecting under high pressure.
12/01/16 12:28:15 31YG0610_019 OPERATION PRIMING THE PUMP Before starting the engine, remove the filler cap from the pump chamber, and completely fill the pump chamber with water. Reinstall the filler cap and tighten it securely. Priming water capacity: WT20X: 3.70 US gal (14.0 L) WT30X, WT40X: 3.96 US gal (15.0 L) Operating the pump dry will destroy the pump seal. If the pump has been operated dry, stop the engine immediately, and allow the pump to cool before priming.
