CAUTION
To prevent the engine from accidentally starting, disconnect the spark plug lead before servicing the engine.
See the engine owner’s manual for a summary of maintenance intervals for the items listed below. Follow either the hourly or the calendar intervals, whichever come first. More frequent service may be required, depending on your specific application and operating conditions. Table D.1 shows engine main- tenance replacement parts and numbers.
OIL: Check the oil level after every 5 hours of operation or daily. BE SURE TO MAINTAIN THE OIL LEVEL.
Change the oil the first time after 5 hours of opera- tion. Then, under normal operating conditions, change the oil after every 50 hours or once a year, whichever occurs first. If the engine is operated under heavy load or in high ambient temperatures, change the oil every 25 hours.
Drain the oil from the drain plug located on either side of the engine bottom, as shown in Figure D.1. Refill through the oil fill plug until the oil reaches the top of the fill hole. Use the grade and viscosity recommend- ed in the engine owner’s manual.
