How to use the vacuum cleaner to vacuum liquids?

To vacuum liquids, remove the filter bag. Make sure the cartridge filter is in place. Plug in the appliance and turn it on. When the tank is full, a float blocks the suction opening and the speed increases. Stop the appliance immediately and empty the tank.

What to do if the suction power decreases?

Check the following points: the accessory, hose or tubes may be blocked (unblock with a stick). The filter bag may be full (replace it). The cartridge filter may be dirty (remove it, tap it or clean it under water and let it dry completely).

Can I vacuum hot ashes?

No, it is forbidden to vacuum ashes or burning or glowing objects. This presents a fire risk.

How to clean the cartridge filter?

Remove the filter and tap it to remove dirt. If dirt does not come off, clean it under water. Let it dry completely before reassembling. Replace it if damaged.

Turn off the appliance and unplug it. Open the lid, remove the full bag and insert a new original Kärcher filter bag. Close the lid. Be careful not to overfill the bag to prevent it from bursting.

Please read and comply with these original operating instruc

tions prior to the initial operation of your appliance and store them for later use or subsequent owners.

Proper use

The appliance is intended for use as a wet and dry vacuum cleaner corresponding to the descriptions given in these operating instructions and the safety notes.

• Protect the unit from rain. Do not store outside.
• This device may not be used to suck in ash and soot.

Use the wet/dry vacuum cleaner only with:
- Original filter bag.
- Original spare parts, accessories and special accessories.

The manufacturer is not responsible for any damages that may occur on account of improper use or wrong operations.

Environmental protection

The packaging material can be recycled. Please do not place the packaging

into the ordinary refuse for disposal, but arrange for the proper recycling.

Old appliances contain valuable materials that can be recycled. Please arrange for the proper recycling of old

appliances. Please dispose your old appliances using appropriate collection systems.

Disposing the filters and filter bags

Filters and filter bags are made from environment-friendly materials.

They can therefore be disposed off through the normal household garbage provided you have not sucked in substances that are not permitted to be thrown into household garbage.

Safety instructions

• This device is not intended for use by persons (including children) with reduced physical, sensory or mental abilities or lacking experience and/or knowledge, unless they are supervised by a person responsible for their safety or are instructed by these persons on the use of the device.

Children should be supervised, to ensure that they do not play with the device.

• Switch the appliance off after every use and prior to every cleaning/maintenance procedure.
• Risk of fire. Do not vacuum up any burning or glowing objects.
• The appliance may not be used in areas where a risk of explosion is present.

△Electrical connection

The appliance may only be connected to alternating current. The voltage must correspond with the type plate on the appliance.

Risk of electric shock

Never touch the mains plug and the socket with wet hands.

Do not pull the plug from the socket by pulling on the connecting cable.

Check the power cord with mains plug for damage before every use. If the power cord is damaged, please arrange immediately for the exchange by an authorized customer service or a skilled electrician.

To avoid accidents due to electrical faults we recommend the use of sockets with a lineside current-limiting circuit breaker (max. 30 mA nominal tripping current).

Caution

Certain materials may produce explosive vapours or mixtures when agitated by the suction air!

Never vacuum up the following materials:

• Explosive or combustible gases, liquids and dust particles (reactive dust particles)
• Reactive metal dust particles (such as aluminium, magnesium, zinc) in combination with highly alkaline or acidic detergents
• Undiluted, strong acids and alkalies
• Organic solvents (such as petrol, paint thinners, acetone, heating oil).

In addition, these substances may cause the appliance materials to corrode.
