BLADE BRUSH ADJUSTMENT
The blade brush is properly set when the machine leaves the factory, however,
it wears out during operation and needs to be adjusted periodically. The blade
brush assembly is shown in the photo. In order to adjust it, the nut on the
adjusting bolt needs to be loosened and the brush mounting bracket turned until
the wires from the brush touch the bottom of the blade gullets as shown and then
tighten the adjusting nut.
If the brush gets worn to approximately 70% of its original diameter it should
be replaced. A brush may be purchased through a HYD-MECH dealer in your
area.
