Maintenance and Storage
Pump Oil Change
1)Place a suitable container below the pump to catch 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 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 half way point on the oil sight glass (see pump oil capacities below). For Comet pumps use Universal Tractor Transmission Oil or Mobil1 15W50 synthetic oil. For Cat pumps use SAE30
