Use the battery-operated sweeper for cleaning surfaces indoors and outdoors.

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 representatives must be driven on and cleaned.

The device is not designed for continuously driving on slopes.

Do not drive on slopes with a gradient of 12% 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). They form explosive vapours or mixtures in conjunction with the suction air.

Never sweep or suction up acetone, non-diluted acids or solvents, 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.

The device is suitable for the following surfaces:

• Asphalt

• Industrial floors

• Screed

• Concrete

• Paving stones

• Carpets (only with optional kit)

The sweeper operates using the direct-throw principle.

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

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

Safety devices protect the user and may not taken out of operation or functionally circumvented.

Adhere to the safety instructions in the chapters!

However, keep in mind that lead-acid batteries contain sulphuric acid which can cause serious chemical burns and corrosion.

1. If there is spillage or, if the battery is leaking, acid is escaping, lay down a binding agent such as sand. Do not let it reach the sewer system, soil or a body of water.

2. Neutralise the acid with lime/baking soda and dispose of it according to local regulations.

3. Contact a waste management company to dispose of faulty batteries.

4. Rinse out your eyes or rinse off your skin with copious amounts of fresh water if acid splashes into your eyes or onto your skin.

5. Then consult a doctor immediately.
