Once the old oil is completely drained, which should take at least several minutes, use a clean rag to wipe down the drain hole and the mesh filter hole. Screw the oil drain plug (with a new aluminum crush washer) and the plastic mesh filter back into the case.
Use the owner's manual (or markings on the engine) to find out the engine's oil capacity, fill it up with that amount-- minus about one half quart-- by placing a funnel into the oil filler hole.
Screw in the oil filler cap and start up the engine. Let the engine idle for about a minute, then shut it off.
