The sweeper is designed for commercial use. Only use the sweeper in accordance with the information in these operating instructions. Any other use is considered improper use. The manufacturer assumes no liability for any resultant damage. The user is solely responsible for the risk. No modifications must be made to the sweeper. Only the areas approved by the company or the company's rep- resentatives must be driven on and cleaned. Foreseeable misuse The device is not designed for continuously driving on slopes. Do not drive on slopes with a gradient of 15% for longer than 3 minutes. Never sweep or suction up explosive liquids, gases, non-diluted acids or solvents (e.g. petrol, paint thinner, heating oil) because they form explosive vapours or mixtures in conjunction with the suction air. Never sweep or suction up acetone, non-diluted acids or sol- vents, as they will corrode and damage the materials used on the device. Never sweep or suction up reactive metal dusts (e.g. aluminium, magnesium, zinc). They form explosive gases in conjunction with highly alkaline or acidic cleaning agents. Do not sweep or suction up burning or smouldering objects. There is a risk of fire. Do not sweep up any harmful substances. Standing in hazard zones is prohibited. Operation in explosive spaces is prohibited. Carrying passengers is prohibited. This device must not be used to push/pull or transport objects. Suitable sweeping surfaces ● Asphalt ● Industrial floor ● Screed ● Concrete ● Paving stones Function The sweeper operates using the direct-throw principle. p. 29

1. The rotating side brush cleans corners and edges of the

sweeping surface, and conveys the waste into the path of the roller brush.

2. The rotating roller brush conveys the swept material directly

into the waste container.

3. The dust which is swirled up in the waste container is separat-

ed by a dust filter, and the suction fan suctions the filtered clean air.

4. The dust filter is cleaned manually by the user.
