Read these original instructions and the safety instructions chapter before using the device for the first time. Act in accordance with them.

Keep them safe for future reference or for future owners.

Please report any defects or shipping damage identified on the vehicle when it is handed over directly to your dealer or department store.

The packing materials can be recycled. Please dispose of packaging in accordance with the environmental regulations.

Electrical and electronic appliances contain valuable, recyclable materials and often components such as batteries, rechargeable batteries or oil, which - if handled or disposed of incorrectly - can pose a potential threat to human health and the environment. However, these components are required for the correct operation of the appliance. Appliances marked by this symbol are not allowed to be disposed of together with the household rubbish.

Current information on content materials can be found at: www.kaercher.com/REACH

Vehicles that are no longer fit for service contain valuable recyclable materials. We recommend you cooperate with a waste management company with regard to the disposal of your vehicle.

The warranty conditions issued by our relevant sales company apply in all countries. We shall remedy possible malfunctions on your appliance within the warranty period free of cost, provided that a material or manufacturing defect is the cause. In a warranty case, please contact your dealer (with the purchase receipt) or the next authorised customer service site.

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 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 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.

• Asphalt

• Industrial floor

• Screed

• Concrete

• Paving stones

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!

Observe the following warnings when handling the batteries:

	Observe notes in the instructions for the battery, on the battery and in these operating instructions.
	Wear eye protection.
	Keep acids and batteries away from children.
	Risk of explosion
	Fire, sparks, open flames and smoking are prohibited.
	Risk of acid burns
	First aid.
	Warning
	Disposal
	Do not throw batteries in the bin.

When used normally, and when observing the instructions, lead-acid batteries do not pose any risk.

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.
