Dust extraction machines are safety devices for the prevention or elimination of hazards according to the DGUV regulation:

• For servicing performed by the user, the device must be disassembled, cleaned and maintained only to the degree that this is possible without presenting a danger to the maintenance personnel and other persons. Suitable precautionary measures include detoxification before disassembly. Make provisions for local forced ventilation at the location where the device is to be disassembled, for cleaning the maintenance surface and to ensure adequate protection for the personnel.

• The exterior of the device should be detoxified by vacuuming and wiped clean, or treated with sealant before being removed from the hazardous area. All device parts must be regarded as contaminated when they are taken from the hazardous area. Suitable measures must be taken to prevent distribution of the dust.

• All contaminated objects resulting from maintenance and repair work that cannot be satisfactorily cleaned must be correctly disposed of. Such objects must be disposed of in sealed bags in accordance with the applicable regulations for the disposal of this type of waste.

• The suction hose ports are to be closed using the sealing plugs during transport and maintenance of the device.

1. Note that you can carry out simple maintenance and care work yourself.

2. Clean the surface of the device and the interior of the container regularly with a moist cloth.

3. Carry out a regular visual inspection for clogging of the hoses.

Have the device regularly inspected according to the respective national accident prevention regulations. Maintenance work as specified by the manufacturer must be performed by a technically qualified person at the specified regular intervals and in accordance with the applicable regulations and safety requirements. Work on electrical components may only be performed by a qualified electrician. Please contact a KÄRCHER branch office if you have any questions.
