    Notes on safety/product selection Notes on safety/product selection 1.1 Approved use The device is approved for use in applications described in the Operat- ing Instructions only. Any other use is not approved and can lead to accidents or the destruction of the device. Non-approved use will result in the immediate expiry of all guarantee and warranty claims against the manufacturer.

  • Page 7: Service/Repair

    All devices that fall under the directive must feature this logo: Can we be of assistance? Webtec offers you the option of returning your old device to us at no ex- tra charge. Webtec will then professionally recycle and dispose of your device in accordance with the applicable law.
  • Page 8 What do you have to do? Once your device has reached the end of its service life, simply return it by parcel service (in the box) to your Webtec sales branch responsible for customer care - we will then initiate the necessary recycling and dis- posal measures.

  • Page 9: Device Version/Range Of Supply

    Device version/range of supply Device version/range of supply The measuring instrument and sensors enable the user to measure all relevant parameters in a hydraulic system. Parameters: • [bar/psi] Pressure, Dp (load sensing pumps) • [°C/°F] Temperature • [L/min/G/min] (U.S) volumetric flow rate • [1/min] RPM Automatic sensor recognition means the measuring instrument is simple to operate.

  • Page 10: Initial Use

    Initial use Initial use The measuring instrument is supplied with rechargeable batteries fitted at the factory. Charge the rechargeable batteries for at least 3 hours before using for the first time. The device is then ready for use. 3.1 Charging the batteries/battery status indicator If the battery power is too low, the battery symbol flashes and the meas- uring instrument turns off automatically.
