Frequently Asked Questions - HC 503-V Cocraft

What type of oil should I use for the Cocraft HC 503-V compressor?

Use an oil suitable for air compressors such as SAE 30 or ISO 68. If not available, SAE 10-30 engine oil can be used as a substitute.

How do I change the oil in the compressor?

Switch off and unplug the compressor. Remove the oil filler cap, tilt the compressor to drain oil into a receptacle. Refill with approximately 400 ml of new oil until the level is at the middle of the oil window. Refit the cap.

What maintenance is required after the first use?

After the first 10 hours of operation, change the oil. Thereafter, change the oil and clean the air filter every 120 hours. Also check the safety valve and pressure gauges.

How do I test the safety valve?

Unscrew the uppermost nut until loose, then pull it out to open the valve. If working properly, air will seep out. Retighten the nut after testing.

What should I do if the compressor does not start?

Check if it is plugged into a live wall socket. If the motor overload cut-out has tripped, reset it by pushing the reset button (item 1). Check for a damaged mains lead.

How do I drain condensation from the air tank?

Open the drain tap (item 6) at the bottom of the tank to release moisture. Make it a habit to do this regularly.

Why is the pressure build-up low or absent?

Check for leaks at the safety valve, drain tap, and hose connections. Ensure the air filter is not clogged. Also verify the safety valve is not leaking.

What safety precautions should I take when using the compressor?

Always wear ear defenders and safety goggles. Never aim compressed air at people. Use the ON/OFF button to switch off, never pull the plug. Unplug before servicing.

Can I use an extension cord with the compressor?

Long extension cords can cause voltage drops and trigger the overload cut-out. If necessary, use a heavy-duty cord suitable for the power rating.

How do I clean the air filter?

Remove the air filter (item 2) and clean it with a suitable solvent or replace if clogged. Do not use flammable liquids.

Product description

The compressor increases the pressure of the air which is pumped into the pressure vessel. When the air pressure in the vessel reaches max, a pressure switch switches off the motor driving the compressor. At the same moment, the air in the compressor is released. This occurs to reduce the pressure in the compressor so that it can restart when the pressure drops to below the minimum pressure. A safety valve releases the air in the pressure vessel if the pressure switch should fail to turn the motor off.

Buttons and functions

1. Overload safety cut-out
2. Air filter

3. Air tank (pressure vessel)

4. Oil inlet

5. Window for checking oil level

6. Drain tap

7. [På/av] On/off switch

8. Pressure gauge – working pressure
9. Air outlet
10. Pressure regulator (working pressure)
11. Pressure gauge – tank pressure
12. Safety valve (pressure relief valve)

Getting started

1. Attach the wheels, rubber feet and air filter.

1. If the oil inlet (4) is fitted with a transit bung, remove it and replace it with the proper oil filler cap.
2. Pour approximately 400 ml oil into the oil inlet and fit the proper oil filler cap. Check the oil level through the oil level window (5).
3. Place the compressor in a clean, dry and well-ventilated location.
4. Make sure that it is stable and cannot tip over.
5. Make sure that the oil level is up to the red circle in the oil level window (5).
6. Connect the mains lead to a 230 V wall socket.

Before using the air compressor for the first time:

Open the drain tap (6) in the bottom of the air tank, switch the compressor on (by pulling the button of the ON/OFF switch (7) up) and let it run for 10 minutes to lubricate all the moving parts. Close the drain tap.

Instructions for use

1. Check the oil level in the window (5).
2. Attach the appropriate air tool for the work you wish to undertake: blow gun, spray gun, tyre inflator, etc.
3. Read the instruction manual of the connected air tool and if necessary, set the recommended working pressure using the pressure regulator (10).
4. When you have finished work and the compressor has been turned off, the pressure must be released by pulling out the safety valve (12).

Use an oil suitable for air compressors such as SAE 30, ISO 68 or equivalent.

Motor overload cut-out

• If the safety cut-out has tripped, the motor has been overloaded in some way.
• The button on the motor overload cut-out (1) will pop out a couple of millimetres when it has been tripped and is reset by pushing it back in.
• There are a number of possible reasons why the overload cut-out might trip such as a voltage drop caused by the use of long extension leads, low ambient temperature (under 10 °C), or that the pressure switch is not used to turn the compressor on/off in the event of a power cut for example.

Care and maintenance

• Repairs must only be carried out by qualified service technicians and only using original spare parts.
- An initial replacement of the oil in the air compressor should be carried out after 10 hours of operation.
- Change the oil and clean the air filter after every 120 hours of use. Check the safety valve and pressure gauges at the same time.
- Test the safety valve by unscrewing the uppermost nut until it is loose and then pulling it out until the spring-loaded valve opens. If the safety valve is working properly (and the air tank is under pressure) air should seep out through the safety valve. Once the valve has been tested, screw the uppermost nut back in again.
- Perform a visual inspection at least once a year to check that the inside and outside of the air tank is free of corrosion. Under no circumstances must the wall thickness of the air tank be less than 2 mm.
- Under no circumstances must the safety valve be tampered with or blocked.
- Regularly check that the ventilation hole in the oil filler cap (4) is open.
- Regularly check that all bolts holding the compressor and air tank together are tight.
- Make it a habit to open the drain tap (6) and release any condensation inside the air tank.
- Do not clean the compressor or air tank with solvents or flammable liquids.
- If the compressor is not to be used for a long time: Unplug the mains lead, empty the air tank

and open the drain tap (6).

Changing the oil

1. Before changing the oil, make sure that the air compressor is switched off and unplugged from the wall socket.
2. Remove the oil filler cap from the oil inlet (4).
3. Tilt the compressor so that oil can run out of the oil filler hole into an appropriate receptacle.
4. Let the oil completely drain from the compressor.
5. Replace with new oil until the oil reaches the middle of the oil-display window. Refit the oil filler cap.

- Oil requirement, approx. 400 ml (not included).

- Use an oil suitable for air compressors such as SAE 30, ISO 68 or equivalent. Compressor oil is especially designed for compressors, amongst other things it has additives that prevent foaming. If no compressor oil is available then SAE 10–30 engine oil can be used as a substitute.
