Frequently Asked Questions - AS20W WilTec

How do I use the WilTec AS20W compressor?

Connect the compressor to a 12 V DC power source (e.g., vehicle cigarette lighter). Attach the appropriate nozzle to the hose, then to the item to be inflated. Switch on the compressor and monitor the pressure gauge. When desired pressure is reached, switch off and disconnect.

What is the maximum pressure of the AS20W?

The maximum pressure is 150 PSI. Do not exceed this limit to avoid damage or injury.

Can I use the compressor for other inflatables besides tires?

Yes, the included adapters allow inflation of balls, air mattresses, inflatable boats, and more. Use the appropriate nozzle.

How do I maintain the compressor?

Keep the compressor clean and dry. Check the air filter (if present) and ensure the hose is not kinked. Store in a cool, dry place. Replace the fuse if it blows.

What safety precautions should I take?

Always read the manual. Do not leave the compressor unattended while running. Do not use in wet conditions. Keep away from children. Do not exceed rated pressure.

Why does the compressor stop suddenly?

The compressor has overheat protection. If it stops, let it cool down for 15-30 minutes before restarting. Also check the fuse.

Can I replace the fuse?

Yes, the fuse is user-replaceable. Typically a 10A or 15A blade fuse. Unscrew the holder, replace with same rating, and reassemble.

What is the typical inflation time for a car tire?

For a standard car tire (e.g., 195/65R15), from 0 to 32 PSI, it takes approximately 3-5 minutes depending on the initial pressure.

Is the compressor suitable for large truck tires?

The AS20W is designed for passenger vehicles and light duty. It may struggle with very large tires due to limited flow rate; prolonged use may trigger overheat protection.

Where can I find spare parts or service?

Contact WilTec customer support or visit their website for spare parts. For repairs, consult an authorized service center. The fuse is available at auto parts stores.

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.
- 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 has to 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 type plate of the device must match the existent mains voltage.
- Never lift, carry, or fix the device by using the power cable.
• Make sure that the electrical plug connection is protected from flood and moisture.
• Before working on the device (maintaining, repairing, cleaning it), pull out the plug.
- The user is responsible for complying with local safety and mounting regulations Ask an electrician, if necessary.
• In case of device failure, repairs can only be carried out by an electrician.

NOTE:

• 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, please contact your seller.
• Always release the water by opening the drain valve 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 device in areas with steam or moisture or close to 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 power

cable away from hot objects, oil, and sharp edges; protect it against breaking. Do not pull the power cable to unplug the plug from the power socket.

- 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.

- Do not store the compressor with the plug plugged in. 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 use it if you are tired. Persons under the influence of alcohol, drugs, or medicine must not use the device. Drowsiness leads to dangerous situations!

- 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. For repairs, only use original spare parts. Do not make any technical modifications to the compressor. In case you cannot eliminate the malfunction, hand over the device to an expert for control and repair.

Notes

• You may use nozzles from 0,2 to 1,0 mm.
• The compressor has a 9.51 mm ( 18 ) outlet (male 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 by the pressure gauge.

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.
- 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).
• The maximum pressure is the pressure measured only inside the compressor itself.
- On the outlet of the compressor, there is a lower pressure; the pressure that you actually work with remains. The operating pressure may vary according to the connected airbrush gun.
