Summary of Contents for Micron Herbi4

  • Page 3: Table Of Contents

    2,000 rpm to produce uniform spray droplets of around 250 micron; large enough to minimise any risk of spray drift. Liquid is fed by gravity through colour coded feed nozzles. The HERBI 4 can apply herbicides to borders, pathways, ditches and larger areas by making a series of consecutive spray passes.

  • Page 4: Safety

    Specially designed Micron Micropak backpacks and a shoulder strap are available for use with the HERBI 4. The sprayer can be supplied with a handle/valve conversion as the HERBI 4 Extra (see page 14) which allows Micron spray bottles to be directly fitted to the sprayer.

  • Page 5: Preparing For Spraying

    1) Extend the sprayer and securely connect the feed tube to the flow valve. Instructions on assembling Micron Micropak backpacks are contained in the tank. The shoulder strap (if supplied) should be connected to the battery case end cap.

  • Page 6: Mixing, Filling And Calibration

    Mixing and filling is generally the most hazardous process in the spraying operation. Always follow the label instructions. Always use a filter (fitted in the Micron Miropak backpacks) and use a funnel if filling a container with a small neck. Only mix enough spray for the area to be treated thereby avoiding the need for disposal of unused spray mix.
  • Page 7 HERBI 4 at concentrations greater than recommended on the label. Micron do not generally recommend using spray mixes of more than ten times the maximum concentration recommended for high volume application with knapsack sprayers. The safest product and lowest dose rate appropriate for the treatment should be used at all times.
  • Page 8 Fill the tank. Wipe the tank with a dry cloth Mix well by gently shaking the tank. Place the tank on the operator‘s back. Examples of mixing spray – for 1 hectare a) glyphosate (360 g/l) 2 litres b) 2,4-D (500 g/l) 3 litres add water: +8 litres...
  • Page 9 The table below indicates the relationship between total spray volume, flow rate and walking speed for the HERBI 4 as per the following formula: Flow rate (ml/min) = 6 x total spray volume (l/ha) x walking speed (m/s) x band width (m) Total spray volume Band width Feed nozzle Flow rate...

  • Page 10: Before Spraying

    BEFORE SPRAYING Check the wind speed and direction (below 5 kph) is safest. Take special care to avoid drift by keeping the spray head as low as possible. Never spray into the wind and avoid walking into the spray. Always keep the spray head at least 60cm from any part of the body to avoid direct contamination by the spray.

  • Page 11: To Stop Spraying

    It is best to hold the HERBI 4 to the side or the rear so that the operator does not have to walk over the treated area. TO STOP SPRAYING Close the flow valve and then switch off the sprayer. When the atomiser disc has stopped spinning raise the sprayer to an angle of 45 (see below).

  • Page 12: After Spraying

    AFTER SPRAYING 1. Dispose of any surplus spray mix according to the product approval. Store products safely, locked up and out of the reach of children. 2. It is essential to clean the sprayer and tank thoroughly using water and detergent after use.

  • Page 13: Storage

    3. After working with agrochemicals, or handling spraying equipment, always thoroughly wash hands and exposed skin. All protective clothing should be washed separately from other clothing and stored. Contaminated gloves should be washed inside and out. STORAGE Before storing the HERBI 4 for long periods disassemble the sprayer by removing the four screws in the battery case and clean all electrical contacts with a wire brush or similar.
