[0004] The method according to the invention is designed, configured, or prescribed for automatically determining or ascertaining cleaning, maintenance, and / or repair information, particularly the content of such information, for electrically driven machining tools or equipment. The machining tool includes or has optically detectable residues, particularly those on the outside or outside of the tool, which are generated during or as a result of the operation of the tool. The method includes or comprises the following steps: a) optically detecting (particularly automatically detecting) residues, particularly on the tool and / or from the outside; b) classifying, particularly automatically, or categorizing, or identifying, the optically detected residues according to their type or category; c) determining (particularly automatically determining) cleaning, maintenance, and / or repair information based on the classified or categorized type; d) outputting, particularly automatically, the determined cleaning, maintenance, and / or repair information to or for the user and / or maintenance personnel of the tool.

Therefore, it enables the rapid and / or simple determination of cleaning, maintenance, and / or repair information in terms of time.

[0006] Additionally or alternatively, this enables, in particular, the output of determined cleaning, maintenance and / or repair information, thereby enabling the cleaning, maintenance and / or repair of the machining tools to be performed quickly, specifically and cost-effectively by the user and / or maintenance personnel.

[0007] In addition, this enables, in particular, cleaning information to inform users that cleaning that can be performed by the user, especially initially, may be sufficient, and / or, in particular, maintenance and / or repair information to inform users that maintenance and / or repair may be required, which should not / cannot / cannot be performed by the user, and / or should and / or need to be performed by maintenance personnel.

[0008] In addition, or alternatively, this enables, in particular, information on cleaning, maintenance and / or repair, especially regarding the timely inspection or care of machining tools due to failure to inspect or care in a timely manner or too late, particularly in terms of time before the need for major cleaning, maintenance and / or repair of machining tools.

Additionally or alternatively, the processing tools can be horticultural, forestry, and / or construction processing tools and / or cutting tools.

[0010] Residues may include or have a minimal scope or degree. Additionally or alternatively, residues or their type may be such that they may enable the determination of cleaning, maintenance, and / or repair information.

[0011] Based on the residue or its type or classification, cleaning, maintenance and / or repair information, especially the content of the cleaning, maintenance and / or repair information, can be determined. Based on different types of residue or different types or different classifications, different cleaning, maintenance and / or repair information, especially different content of the cleaning, maintenance and / or repair information, can be determined.

[0012] Step a) or optical detection may include, in particular, capturing images of the residue.
