(3) "ENGINE STOPPED" side. (4) "LOW IDLE" side. (5) "ADD" mark. (6) "FULL" mark.
Ensure that oil level gauge (2) is seated.
If the engine is stopped, remove oil level gauge (2). Observe the oil level on "ENGINE STOPPED" side (3). The oil level should be between "ADD" mark (5) and "FULL" mark (6) .
If the engine is operating, reduce the engine speed to low idle. Remove oil level gauge (2) and observe the oil level on "LOW IDLE" side (4). The oil level should be between "ADD" mark (5) and "FULL" mark (6) .
Operating your engine when the oil level is above the "FULL" mark could cause your crankshaft to dip into the oil. The air bubbles created from the crankshaft dipping into the oil reduces the oil's lubricating characteristics and could result in the loss of power.
If necessary, remove oil filler cap (1) and add oil. For the correct oil to use, see this Operation and Maintenance Manual, "Refill Capacities and Recommendations" topic in the Maintenance Section. Do not fill the crankcase above "FULL" mark (6). Clean the oil filler cap. Install the oil filler cap.
