12 BEFORE OPERAT ION ARE YOU READY TO GET STARTED? Knowledge Your safety is your responsibility. A little time spent in preparation will significantly reduce your risk of injury. Read and understand this manual. Know what the controls do and how to operate them.
13 BEFORE OPERATION IS YOUR PUMP READY TO GO? Check the General Conditi on of the Pump For your safety, and to maximize the service life of your equipment, it is very important to take a few m oments before you operate the pump to check its condition.
14 BEFORE OPERATION Check the Suction and Dischar ge Hoses Check the Engine Check the general conditi on of the hoses. Be s ure the hoses are in serviceable condition before connectin g them to the pump. Remember that the suction hose must be reinforced construction to prevent hose collapse.
15 OPERA TION SAFE OPERATING PRECAUTIONS To safely realize the full potential of this pump, you need a complete understanding of its o peration and a c ertain amount of practice with its controls. Before opera ting the pump for the first time, please review the IMPORTANT SAFETY INFORMATION on page and the chapter titled BEFORE OPERATION .
16 OPERATION PUMP PLACEMENT SUCTION HEAD DISCHARGE HEAD T T O O T T A A L L H H E E A A D D For best pump performance, place the p ump 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.
