One of the easiest, cheapest, and most overlooked part of pump maintenance is the oil change. Clean, fresh oil will allow your pump to run better and longer. Contaminated oil is the downfall of many pumps. Make sure you always check your oil level and the clarity of your oil. If you see visible signs of contamination, change it right away.
