Pump Oil Change
1.) Place a suitable container below the pump to catch the used oil, then remove the oil fill cap and oil drain
plug.
2.) Allow the used oil to drain completely, then reinstall the drain plug and tighten securely.
3.) Please dispose of used oil in a manner that is compatible with the environment. We suggest you take used
oil in a sealed container to your local recycling center or service station for reclamation. Do not throw it in
the trash; pour it on the ground or down the drain.
4.) With the pump in a level position, fill to the halfway point on the oil sight glass (see pump oil capacities
below). For Comet pumps use Universal Tractor Transmission Oil or Mobil 1 15W50 synthetic oil. For Cat
pumps use SAE30 non-detergent oil or Cat Pump Oil Item# 22158.
