3. PREPARATION 1. Suction hose Use a commercially available hose, hose connector, and hose bands. The suction hose must be of reinforced, noncollapsible wall or wire braided hose to prevent suction collapse. The suction hose length should not be longer than necessary, as the pump performance is best when the pump is not far above the water level. Self-priming time is also proportional to the suction hose length. Using a longer suction hose will increase the self-priming time.
3. Engine oil [NOTlCE] l l Engine oil is a major factor affecting engine performance and service life. Nondetergent oils and P-stroke oils are not recommended because they have inadequate lubricating characteristics. Check the oil level with the pump on a level surface and the engine stopped. Use Honda 4-stroke oil, or an equivalent high detergent, premium quality motor oil certified to meet or exceed U. S. automobile manufacturer’s requirements for Service Classification 0 20 40 , 60 80 1OO'F SG, SF.
Fuel Recommendation 1. Remove the filler cap check fuel level. level is low. Do not fill above the shoulder of the fuel strainer. 2.
