2.1.5 Malfunction
If any safety-relevant malfunction occurs on the belt grinding attachment or if the processing re-
sponse indicates that such malfunction may have occurred, the belt grinding attachment must be
stopped immediately until such time as the malfunction has been detected and eliminated.
Malfunctions may only be eliminated by authorized specialists.
2.2 Intended use
The belt grinding attachment is meant for grinding sickle-shaped flat knives only. It is meant to be
installed onto KNECHT grinding machines of the USK 160 S series only. All knives must be tight-
ened to the respective grinding plates.
Before starting work on a flat knife, a check must first be carried out as to whether the knife fits
onto the grinding plate. The knife can only be tightened to the grinding plate if it fits, because
otherwise the knife may be damaged.
Any other use is considered improper use. KNECHT Maschinenbau GmbH assumes no liability for
damages resulting from improper use. The user alone bears the risk in such cases.
Use as intended includes the observance of all the instructions in the operating instructions.
The belt grinding attachment is being used improperly if, for example:
• it is installed onto grinding machines other than the KNECHT USK 160 S series,
• the knife is improperly tightened to the grinding plate,
• attachments are not properly mounted,
• knives are sharpened / polished in the opposite direction of the cutting edge on the wet-grinding
belt or wet-honing wheel / finned brush.

Warranty and liability claims in case of personal injuries or property damage are excluded if such
damage is attributable to one or more of the following causes:
• improper use of the belt grinding attachment,
• improper transportation,commissioning, operation and maintenance of the belt grinding attach-
ment,
• operating the belt grinding attachment with defective safety devices, or using improperly at-
tached or malfunctioning safety and protective equipment,
