Why is my Delta DLKC6580V2-1 Air Compressor not supplying enough air to operate accessories?
- C
  Christopher WaltonAug 19, 2025
  Several factors can cause your Delta Air Compressor to not supply enough air. It could be due to prolonged excessive air usage, or the compressor might not be large enough for the air requirement of your accessories. Other potential causes include a hole in the hose, a restricted check valve or air intake filter, air leaks, or a loose belt. To resolve this, decrease your air usage and check the accessory's air requirements. If the requirements exceed the compressor's SCFM or pressure, you'll need a larger compressor. Inspect and replace any damaged hoses. Clean or replace the check valve and air intake filter, and ensure all fittings are tightened. Remember not to operate the air compressor without the filter. Also, check the belt tension.

How to fix air leaks at fittings on a Delta DLKC6580V2-1 Air Compressor?
- A

  If you notice air leaks at the fittings of your Delta Air Compressor, it's likely that the tube fittings aren't tight enough. Carefully tighten the fittings where you hear air escaping. You can also use a soapy water solution to check for leaks. Be cautious not to overtighten the fittings.

Why is my Delta Air Compressor safety valve popping off?
- J
  jacqueline81Aug 26, 2025
  The safety valve on your Delta Air Compressor might pop off because the pressure switch isn't shutting off the motor when the compressor reaches the “cut-out” pressure, or the pressure switch “cut-out” is set too high. Move the On/Auto/Off lever to the “OFF” position; if the unit still doesn't shut off, contact a Trained Service Technician.

  Matthew WilliamsAug 28, 2025
  If you notice an air leak from the safety valve of your Delta Air Compressor, it could be due to a defect in the safety valve. Try manually operating the safety valve by pulling on the ring. If the valve continues to leak after doing this, it should be replaced.

Why does my Delta Air Compressor have a knocking noise?
- K
  Kathleen WardAug 30, 2025
  A knocking noise in your Delta Air Compressor can be caused by several issues. It could be a defect in the safety valve, a defective check valve, a loose pulley or flywheel, loose compressor mounting screws, a loose belt, carbon build-up in the pump, or a belt that's too tight. Try manually operating the safety valve by pulling on the ring; if it still leaks, replace it. Remove and clean or replace the check valve. Tighten the pulley set screw to 145-165 in.-lbs and the flywheel screw to 33-37 ft.-lbs. Also, tighten the mounting screws to 20-25 ft.-lbs. Check the belt tension.

What to do if my Delta DLKC6580V2-1 Air Compressor has air leaks in the air tank or at air tank welds?
- P
  Patrick EdwardsSep 1, 2025
  If you discover air leaks in the air tank or at the air tank welds of your Delta Air Compressor, it indicates a defective air tank. The air tank must be replaced. Do not attempt to repair the leak, drill into, weld, or modify the air tank in any way, as this will weaken it and could cause it to rupture or explode.

How to resolve excessive belt wear on my Delta DLKC6580V2-1 Air Compressor?
- M
  Mark SmithSep 3, 2025
  Excessive belt wear on your Delta Air Compressor could be due to a loose or tight belt, a loose pulley, or pulley misalignment. Check the belt tension.

What to do if air leaks at or inside the check valve of my Delta Air Compressor?
- S
  Sean NelsonSep 5, 2025
  If you're experiencing air leaks at or inside the check valve of your Delta Air Compressor, it suggests that the check valve seat is damaged. The solution is to replace the check valve.

Why does my Delta Air Compressor make a squealing sound?
- S
  Sarah GatesSep 7, 2025
  A squealing sound in your Delta Air Compressor usually indicates that the compressor pump has no oil or the belt is loose. Check the oil level.

What to do if the safety valve on the pump of my Delta Air Compressor “pops” out?
- T
  Travis MillerSep 10, 2025
  If the safety valve on the pump of your Delta Air Compressor “pops” out, it could mean that the pressure switch, check valve, or pump needs servicing. Have it checked by a Trained Service Technician.
