BEFORE USE POSITIONING THE PUMP For optimum performance, place the pump near the water level and use hoses that are no longer than necessary. As “head” (pumping height) increases, pump output decreases. The length and size of the suction and discharge hoses can also effect pump output. The discharge head is always greater than the suction head, so it is important for the suction head to be the smaller part of the total head.
• Oil capacity is 1 Litre. • We recommend you use SAE 15W40 or SAE10W30 oil in this pump, available from your Clarke dealer. 5. Replace the oil filler cap. Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com...
