Maintenance and repairs

5.1

General

We recommend regular inspections of all seals.

Warning!

Disconnect the electrical supply when cleaning, carrying out maintenance,
changing tools or repairing the machine.

Warning!

Use protective equipment as shown on the labelling in the machine.

5.2

Cleaning

Warning!

Do not rinse off the machine using a high-pressure washer, as moisture can
penetrate to the electrical parts and damage the drive system.

•

Always clean the machine after use with a damp sponge or cloth.

5.3

Daily

•

Check for wear to the grinding tools – abnormal or uneven wear may indicate a
damaged grinding holder.

•

Check the tool holder and grinding holder to ensure that no damage or cracks
have arisen. Replace the parts if there is any damage.

•

Check that the brush strip on the grinding cover is not damaged and that it is
correctly attached.

5.4

Every week

•

Wash the machine, see Cleaning, page

•

Check the grinding holders. Remove the tools and run the machine in mid air at
the slowest speed. If the grinding holders oscillate or wobble significantly, they
are damaged.

Tip!

Recondition all the grinding holders at the same time.
