5.If the level is low, add oil of the proper type, up to the “F” mark on the dipstick. (Refer to “Oil Type” on page 5.) Always check the level with the dipstick before adding more oil.
NOTE: To prevent extensive engine wear or damage, always maintain the proper oil level in the crankcase. Never operate the engine with the oil level below the “L” mark or over the “F” mark on the dipstick.
Oil Sentry™
Some engines are equipped with an optional Oil Sentry™ oil pressure switch monitor. If the oil pressure decreases below an acceptable level, the Oil Sentry™ will either shut off the engine or activate a warning signal, depending on the application.
NOTE: Make sure the oil level is checked BEFORE EACH USE and is maintained up to the “F” mark on the dipstick. This includes engines equipped with Oil Sentry™.
Change Oil and Filter, Service Oil Cooler
Change Oil
Change oil after every 100 hours of operation (more frequently under severe conditions). Refill with service class SG, SH, SJ or higher oil as specified in the ‘‘Viscosity Grades’’ table (Figure 3) on page 5.
Change the oil while the engine is still warm. The oil will flow freely and carry away more impurities. Make sure the engine is level when filling, checking, and changing the oil.
Change the oil as follows (see Figures 8 and 9):
1.To keep dirt, debris, etc., out of the engine, clean the area around the oil fill cap/dipstick before removing it.
2.Remove one of the oil drain plugs, oil fill cap, and dipstick. Be sure to allow ample time for complete drainage.
3.Reinstall the drain plug. Make sure it is tightened to 13.6 N·m (10 ft. lb.) torque.
4.Fill the crankcase, with new oil of the proper type, to the “F” mark on the dipstick. Refer to “Oil Type” on page 5. Always check the level with the dipstick before adding more oil.
5.Reinstall the oil fill cap and tighten securely. Reinstall dipstick.
NOTE: To prevent extensive engine wear or damage, always maintain the proper oil level in the crankcase. Never operate the engine with the oil level below the “L” mark or over the “F” mark on the dipstick.
