Fill upto, but not above, the “F” mark on the dip-stick. Crankcase capacity is 1.85 quarts (1.75liters) plus 1/2 pint (0.24 liters) for the new oilfilter.IMPORTANT: Check the dipstick reading be-fore adding the last 1/2 pint of oil and fill only tothe “F” mark. DO NOT overfill the crankcase(oil above “F” mark) as this CAN result in en-gine overheating, loss of power, and possibleengine damage.10. Start the engine and check for oil leaks aroundthe oil filter. Stop the engine, recheck the oillevel, and add oil if necessary. (When the en-gine is first operated with a new oil filter, the oillevel drops slightly as the filter is filled with oil.)
