Frequently Asked Questions - KrümelChef KC502 GRAEF

How to recharge the KrümelChef KC502 vacuum cleaner?

Plug the provided charger into the charging port on the device, then connect it to a power outlet. The switch indicator blinks red during charging and turns solid white once the battery is fully charged.

How to clean the HEPA filter?

Remove the HEPA filter from the dust container. Do not rinse it under water. Use a small brush to gently remove dust. Reassemble after cleaning.

Why does suction power decrease?

Several possible causes: the filter is clogged (clean it), the container is full (empty it), or the battery is low (recharge the device). The red indicator signals a low battery.

Can I use the vacuum cleaner without a filter?

No, never use the appliance without a filter (HEPA or nylon). This could damage the motor and reduce suction efficiency.

Can I vacuum liquids with this vacuum cleaner?

No, this vacuum cleaner is designed only for dry crumbs and dust. Never vacuum liquids, as this presents an electric shock hazard and can damage the device.

What to do if the device does not charge?

Check that the charger is properly connected to the outlet and the charging port of the device. If the problem persists, the charger may be damaged; contact Graef customer service for a replacement.

How to empty the dust container?

Unscrew the container in counterclockwise direction (follow the open lock arrow). Remove the filters, empty the container and clean it with a damp cloth if necessary. Reassemble in reverse order.

How to change the filters?

The HEPA and nylon filters are removable. Remove them from the container and replace them with original Graef parts as soon as suction power decreases despite cleaning.

What is the warranty period?

Graef offers a 24-month manufacturer warranty from the date of purchase, covering manufacturing and material defects. Damages due to improper use are excluded.

How to contact Graef customer service?

You can reach customer service by phone at [phone] or by email at [e-mail] for any questions or technical issues.

Disposal of the packaging

The packaging protects the unit against transport damage. The packaging materials are selected according to the environmental compatibility and disposal-related aspects and can therefore be recycled. The return of packaging into the material cycle saves raw material and reduces the waste volume. Dispose of the packaging material no longer needed at collection points for the "Green Dot" recycling system (in Germany).

If possible, keep the original packaging during the guarantee period of the unit in order to be able to pack the unit correctly in case of guarantee.

Disposal of the battery

• The battery pack must be removed to dispose the unit.
• Make sure that the battery pack is completely discharged. Check this by trying to switch on the unit.
• If the battery pack has not been completely discharged and an electrically conductive connection has been established, there is danger of a short circuit.
• In the event the unit is starting, let the unit run until it will switch off automati-

cally. Try to switch on the unit again in order to verify that the battery pack is completely discharged. Repeat the entire process so long until the unit cannot be switched on any more.

• Loosen the screws on the handle of the unit and dismantle the housing shells.
• Despite of complete discharge, the battery pack has a remaining capacity which can be released in case of a short circuit.
• Remove the battery pack and disconnect the connections of the battery pack individually one by one. Using insulating tape, stick over the individual connections to isolate the contacts.

Battery packs must not be disposed of in household rubbish. Take it to the waste collection depot intended for the purpose.
