Frequently Asked Questions - AS196A WilTec

What is the maximum pressure of the AS196A compressor?

The compressor has a pressure range of 0–4 bar according to the specifications. However, the high-pressure switch allows a maximum pressure of up to 6 bar. The working pressure is adjustable via the pressure regulator.

How do I drain the water from the tank?

Use the water drain plug located at the bottom of the pressure regulator or tank. Open it periodically, especially before long-term storage, to release condensed water.

The motor runs but no air comes out. What should I do?

Check if the air outlet is blocked or if the cylinder valve is installed correctly. Also inspect the valve screws and diaphragm screws; they may be loose or incorrectly positioned.

Can I use this compressor for airbrushing?

Yes, the AS196A is specifically designed for airbrushing, including art, modelling, tattoos, and nail design. It has a low-pressure auto-stop switch (position 1) for airbrush tools.

What type of oil does the compressor require?

This compressor is oil-free. It uses a piston design that does not require oil lubrication, ensuring clean, oil-free air output.

The compressor turns on and off frequently. Is this normal?

Frequent cycling can indicate a leak in the system. Perform a leakage check: after reaching maximum pressure, observe the pressure gauge. If it drops quickly, inspect all connections and hoses for leaks and seal them.

What is the noise level of this compressor?

The noise level is approximately 45 dB(A), which is very low, making it suitable for indoor use without causing disturbance.

How do I adjust the operating pressure?

Use the pressure regulator knob. Pull it up to adjust, turn clockwise to increase pressure or counterclockwise to decrease. Push down to lock the setting. Check the pressure gauge for the desired value.

Can I use an extension cord?

Yes, but only approved extension cords with a minimum wire cross-section of 1.5 mm². Ensure the cord is suitable for outdoor use if used outside.

Where can I find replacement parts?

Refer to the exploded view and parts list in the manual. Use only original WilTec spare parts. Contact WilTec service or your dealer for replacements.

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.

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.

Operating the pressure regulator with filter

a) Pressure regulator
b) Pressure gauge
c) Water drain plug

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.
