Usage Notes

  • Avoid using extension cords, will trip breakers. 20A breaker preferred.
  • Do not tip the unit, it will pour oil from the pump into the tank.
  • Before use, check the drain valve underneath, it should need to be closed. DO NOT overtighten.
  • After use, always drain the tank. Use the blowout valve first, then open the drain valve underneath and leave it open. DO NOT OVERLOOSEN. This drains the air completely but also the water that has accumulated inside the tank. If you forget to do this the tank will rust and then eventually rupture. This is a big deal, remember to do it every time.
  • Occasionally overheats and trips internal motor breaker, is self-resetting when cool again. Avoid this when possible and moderate use accordingly.
