Changing the Engine Oil

Change the oil after the first five operating hours and then
after every 50 operating hours or every season. Run the
engine just before changing the oil to warm the oil. Warm
oil flows better and carries more contaminants.
Note: Change the oil after every 25 operating hours when
operating under a heavy load or in high temperatures.
