Frequently Asked Questions - AF186 WilTec

How do I start the compressor?

Plug into a grounded outlet, ensure the pressure switch is set to 'ON', and wait for the tank to fill. The unit will stop automatically at max pressure.

What type of oil should I use?

Use SAE 30 non-detergent compressor oil. Check the oil level before each use and change every 100 hours of operation.

How often should I drain the tank?

Drain the condensation from the tank daily after use to prevent rust and extend the compressor's life.

Why is the compressor not building pressure?

Check for leaks in the hose or fittings, ensure the air filter is clean, and verify that the pressure switch is working. If the problem persists, consult the manual.

Can I use this compressor for painting?

This compressor is suitable for light spray painting with a water trap and proper regulator. For best results, use a spray gun rated for low CFM.

What is the maximum duty cycle?

The AF186 has a 50% duty cycle: run for 10 minutes, then rest for 10 minutes. Overrunning may cause overheating.

How do I clean the air filter?

Remove the filter cover, take out the foam element, wash with mild soap and water, dry thoroughly, and reinstall. Replace if damaged.

Is the compressor noisy?

Yes, it operates at around 85 dB. Use ear protection and place the compressor on a stable surface to reduce vibration noise.

Can I adjust the pressure?

Yes, use the built-in pressure regulator knob to set the output pressure between 0 and 8 bar. The gauge shows the tank pressure and outlet pressure.

What spare parts are available?

Common spare parts include replacement hoses, quick connectors, air filters, pressure switches, and safety valves. Contact WilTec support for ordering.

Safety instructions

Caution!

- The use of this device is only allowed with a fault current protection switch with a triggering nominal current up to 30 mA (according to VDE 0100 Article 702 and 738).

- The device is not intended for use by persons (including children) with impaired or limited physical, sensory, and mental abilities, or lack of experience and/or real knowledge, unless they are supervised by a person responsible for their safety or follow the instructions made by this person on how to correctly use the device.

• Children should be supervised to ensure that they do not play with the device.

Attention!

• The compressor head can become very hot. Burning hazard!

- Perform a visual inspection of the device before every use. Do not use the device if the safety appliances are damaged or worn out. Never override safety regulations.

• Only use the device accordingly to the intended purpose stated in this manual.

- You are responsible for the safety of the working zone.

- If the cable or the plug is damaged due to external influences, the cable must not be repaired, but must be replaced with a new one. This work can only be carried out by an electrician.

- The voltage of 230 V AC indicated on the nameplate of the device must match the existent mains voltage.

- Never lift, transport, or suspend the device by its power cord.

• Make sure that the electrical plug connection is protected from flood and moisture.

• Before any maintenance work or adjustment, pull out the plug.

- The user is responsible for complying with local safety and mounting regulations. Ask an electrician if you have questions.

• In case of device failure, repairs can only be carried out by an electrician.

Notes!

- Choose the right compressor with the appropriate air volume and air pressure to match the actual work requirements.

- Never expose the device to dust, acid, steam, explosive or flammable gases, or weather influences (rain, sun, fog, snow).

- The vacuum pump can only be operated in an appropriate environment (good ventilation, ambient temperature +5 °C–+40 °C).

- Never use the compressor barefoot or with wet hands or feet.

- Never allow children to touch the switched-on compressor or to insert the plug. It may cause burns or electric shocks.

• Do not open or damage any part of the compressor. If necessary, contact a qualified person.

- By opening the drain valve, the water can be evacuated. Always release the water before not using the compressor for a long time. Store the compressor in a well-ventilated place.

- Always wear protective goggles. Under no circumstances should you direct the airflow towards your body or other persons' bodies or animals.

• Never use the compressor in areas with vapours or humidity or near bodies of water.

- Switch off the compressor if you do not use it. Disconnect from mains before you repair, recondition, maintain, clean, or replace parts. Never use the power cable as handle. Keep the cable.

away from heat, oil, or sharp edges. Protect it from breaking. Do not pull out the plug by pulling the power cable.

- If the compressor is used outdoors, only approved extensions may be used. Every wire of the extension cable must have at least a 1.5 ~mm^2 cross-section.

- Store the compressor in a well-ventilated place. Do not allow children or any other people not able to handle this device to play or work with it.

- Be very careful when working with the compressor. Do not perform work with this product when being unalert or influenced by alcohol, drugs, or medicine.

- When beginning work, make sure that all screws are tightened.

- Do not use the compressor if it is damaged. If the compressor makes unusual noises and strong vibrations or if other unusual signs occur that indicate some damage, immediately turn off the compressor. Do not modify the compressor in any way. Only have repairs made by qualified persons and using original spare parts.

User notes

- The compressor has a 9.51 mm ( 18 ) outlet with external thread which can be effortlessly changed to 14 . The matching adapter is not included in the delivery.

- When the compressor is connected by the hose to the airbrush gun, it can be connected to the mains and switched on.

- The maximum pressure is displayed the pressure gauge, the operating pressure can be adjusted by the pressure regulator.

- If the auto-stop mode is activated (repeatedly switched on/off) all screw fittings and connections should be sealed by sealing tape.

Leakage check

• Switch on the compressor and wait until the maximum pressure has built up and the auto-stop function has been activated.
• If there is no leakage, the pressure gauge should display nearly constantly the same range of pressure.
  • A quick decrease of the range of pressure suggests that there is in fact a leakage.
• It is of great importance to seal any leak as soon as possible to avoid any impact on the capacity and efficiency of the compressor.
  • A leakage leads to the auto-stop and auto-start constantly being switched on and off.

Difference between maximum pressure and operating pressure

• The maximum pressure is the highest possible pressure that a compressor can generate.
• The maximum pressure is the pressure measured only inside the compressor itself.
- Once the maximum pressure has been reached, the compressor switches off (auto-stop), and as soon as the pressure starts to decrease, it switches on again (auto-start).
- On the outlet of the compressor, there is a lower pressure. What remains is the pressure that you work with. The operating pressure may vary according to the connected airbrush gun.

Product name:

Type: AFR-2000

Pressure regulator with filter and manometer

Properties

AFR-2000 is an in-line low-pressure regulator with 9 bar (130 psi) manometer and water drain plug. This regulator allows you to control the pressure and helps generating clean, dry, and stable air pressure. The regulator can only be used according to the operating instructions.

Operation:

1. The pressure gauge reports the working pressure of the air tool.
2. Pull up the adjusting knob; a clockwise rotation increases the pressure, a counter-clockwise rotation reduces the pressure.
3. Rotate the adjusting knob to achieve the right working pressure and engage it by pushing it downwards.
4. Do not rotate the knob against high resistance. If necessary, the height and position of the knob can vary slightly.
5. For emptying the condensed water collector, use the water drain plug.
