- Persons with limited physical, sensorial or mental abilities are not allowed to use the device, unless they are supervised and briefed for their safety by a qualified person.
- Keep the device out of reach of children.
- For your own safety always use the quick coupling adaptor to connect the device to the air supply and always regulate the working pressure by using a pressure regulator. Do not exceed the max. permitted working air pressure. Please refer to the Technical Data.
■ Never use oxygen or flammable gases as source of energy.
- Check if all connections and hoses are mechanically secured and if they are functioning properly. Loose hoses may cause severe injuries. Only use quick coupling adaptors.
- Disconnect the air tool from the compressed air source before doing any maintenance work or when not in use.
- Do not modify the device in any way and do not use it for any unintended use. Only use original accessory. Not recommended accessory can bear a risk of danger.
- Should the unit become damaged do not use it any further and have it repaired by a professional or contact our customer service. Do not disassemble the unit or try repairing it yourself.
OPERATION
Intended Use
- The device is designed to check the air pressure and to fill or deflate tyres, such as car, motorcycle, truck, or bicycle tyres.
- The intended use also includes an operation following the operating instructions.
- Any use beyond these parameters (different media, applying force) or any changes (reconstruction, no original accessory) can lead to serious risks and is regarded as use that is contrary to the intended purpose.
Before first Use
Unpack the device and check all parts for any damage in transit. Dispose of packaging materials or store them out of reach of children. There is risk of suffocation!
Notes
- The optimum air pressure of the car tyre not only provides safe performance and durability of your tyres – using the right tyre pressure, recommended by the automobile manufacturer, also can safe fuel.
- You will find the details on the comfortable minimum pressure for your tyres in the instruction manual of your vehicle or e.g. at the door pillar or behind the petrol cap.
- The compressed air, to refill the tyre, has to be oil free. Do not connect an oiler ahead of the unit. It is recommended to use a separate compressed air hose only for working with the device, because there may be oil residues on other compressed air hoses.
Measuring
- Put the valve connector (5) on the tyre valve. To do this, please press down the lever to unlock the clamping mechanism. As soon as you release the lever, the plug clamps at the valve.
- Read the existing pressure from the manometer (1).
Outer rim of the scale = the unit in bar (1 bar = 100 kPa)
Inner rim of the scale = the unit in psi.
Filling
- Screw the air hose (7) and the pistol (8) together.
-
Connect the quick coupling connector (4) of the device with a compressed air supply.
-
Put the valve connection (5) on the tyre valve.
- Press the trigger (6), compressed air flows into the tyre.
The moment you are filling in the air, the manometer (1) shows a pressure that is a little bit higher than the actual tyre pressure. When you release the trigger, you can read the actual tyre pressure on the manometer.
Deflation of Air
If the tyre pressure is too high, use the deflation button (3) and slowly reduce the air pressure to the desired value.
Cleaning and Maintenance
- Do not allow foreign substances and dirt to enter the compressed air nozzle.
- Do not expose the manometer to vibrations or mechanical stress.
- Add a few drops of oil to the sealing of the trigger pin in regular intervals. Apart from that the device is maintenance free.
Storing
- Store the device indoors in a dry place that is protected from dust, dirt and extreme temperatures.
- Store the device out of reach of children.
For storing the device, use the hanger (2).
