●Replacing the brush
If the ends of the brush bristles are worn out so that improperly oriented screws cannot be swept away, please replace the brush.
To replace the brush, please position it as shown below. You can also adjust its position by rotating the timing shaft. 
Remove the brush assembly mounting screws and then the brush assembly. You can disassemble the brush assembly. After the 
brush is replaced, install the brush assembly by reversing preceding steps.

All the above replacement parts are available as options. When they need replacement, contact your local dealer and specify the
