8.2 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 bucket must be used. For more information about repairs contact your
nearest service point.
8.3 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.
Clean the collector box thoroughly, do not leave water in the collector. Empty and rinse the water spraying
system completely.
8.4 Brush
The nylon brush bristles have a long service life in normal operating conditions. As the brush wears down its
diameter decreases, and eventually it will not throw material at sufficient speed for good collecting
performance.
The brush consists of several parallel discs connected on a shaft. If you notice that a specific part of the brush
has damaged or worn clearly more than the rest of it, the discs may be rearranged on the shaft to achieve
more even wearing. The damaged brush discs can be changed individually, but usually a larger section
should be replaced to keep the performance of the broom even. If the damaged brush discs are worn clearly
more than new ones, all of the discs should be replaced at once. Steel bristle discs may also be available,
contact your dealer.
To replace the brush discs the broom shaft must to be removed. The brush is made denser at the ends of the
shaft by setting three discs the same way round at the both ends of the shaft. The discs are held together on
the shaft by a tightening flange. When tightening the flange, the total compression of the discs along the shaft
must not be more than 5 – 10 mm.
8.4.1 Side brush
The side brush has both nylon and steel bristles. Keep the side brush and its pivot joints clean, other
maintenance is not needed.
8.4.2 Side bristle skirts and rubber edge plate
