Mounting/Changing the Diamond Cutting Disc (see figure A)

Wearing protective gloves while inserting and replacing diamond cutting discs is recommended.

Diamond cutting discs become very hot while working; do not touch them until they have cooled.

Always use a diamond cutting disc of the correct size and with the correct locating bore as specified in the technical data.

Use only diamond-tipped cutting discs. Segmented diamond cutting discs may only exhibit negative cutting angles and max. 10 mm slots between the segments.
