Cleaning the attachment
Clean the attachment regularly to prevent accumulation of dirt which is more difficult to remove. A pressure
washer and mild detergent can be used for cleaning. Do not use strong solvents, and do not spray directly at
the hydraulic components, or at the labels on the attachment.

Inspection of metal structures
Also the metal structures of the attachment must be inspected regularly. Check visually for damages and
inspect the quick attach brackets and their surrounding area carefully. The attachment must not be used if it is
deformed, cracked, or torn.
Welding repairs are only allowed to be carried out by professional welders. When welding, only methods and
additives suited for steel used in attachment must be used. For more information about repairs contact your
nearest service point.
