Delta Electronics Air Compressor DLKC6580V2

Motor Pulley/Flywheel alignment

The air compressor flywheel and motor pulley must be in-line (in the same plane) within 1/16"" to assure belt retention within flywheel belt grooves. To check alignment, perform the following steps:

1. Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank.

3. Place a straightedge against the outside of the flywheel and the motor drive pulley.

4. Measure the distance between the edge of the belt and the straightedge at points A1 and A2 in figure. The difference between measurements should be no more than 1/16"".

5. If the difference is greater or less than 1/16"" loosen the set screw holding the motor drive pulley to the shaft and adjust the pulley’s position on the shaft until the A1 and A2 measurements are within 1/16"" of each other.

6. Tighten the motor drive pulley set screw. See Parts manual for torque specifications.

7. Visually inspect the motor drive pulley to verify that it is perpendicular to the drive motor shaft. Points B1 and B2 of Figure should appear to be equal. If they are not, loosen the setscrew of the motor drive pulley and equalize B1 and B2, using care not to disturb the belt alignment performed in step 2.

1. Set the On/Auto/Off lever to ""OFF"".

3. Remove the air tool or accessory.

4. Open the globe valve and allow the air to slowly bleed from the air tank until tank pressure is approximately 20 psi.

6. Drain water from air tank by opening drain valve (counter-clockwise) on bottom of tank.

7. After the water has been drained, close the drain valve (clockwise). The air compressor can now be stored.

A dirty air filter will not allow the compressor to operate at full capacity. Keep the air filter clean at all times.

1. Remove the air filter cover.

2. Remove the air filter from filter cover.

3. Place new air filter into filter cover. Refer to the ""Repair Parts"" for the correct part number.

4. Replace air filter cover and lock into place.

1. Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank.

Air compressor pump intake and exhaust valves

Once a year have a Trained Service Technician check the air compressor pump intake and exhaust valves.

Inspect Air Lines and Fittings for Leaks

1. Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank.

2. Apply a soap solution to all air line fittings and connections/piping.

1. Remove the oil fill plug (A).

2. Remove the oil drain plug (B) and drain oil into a suitable container.

3. Replace the oil drain plug (B) and tighten securely

4. Sowly add compressor oil until the oil level is in the middle of the sightglass (C).

5. Replace oil fill plug (A) and tighten securely.;
