Change of Brushes
Caution
During maintenance service, raise the empty
bucket.
Important
If the brush operation height is inadequate,
cores will not be properly collected.
Important
If the left and right sides of the brushes are at
different heights, the cores will not be
uniformly collected, and the brushes will wear
unevenly.
Important
Replace all brushes. Otherwise the weight will
become unbalanced and vibration may occur.
If the clearance between the rotary brush tips
and the brush frame cannot be adjusted to
approximately 5.0 mm (0.20 in) due to brush
wear, replace the brushes.
Move the machine to level ground.
Apply the parking brake.
Raise the bucket to its highest position.
Stop the engine.
Warning
To keep the position of raised bucket, be sure
to lock it with the cylinder lock.
Lock the bucket with the cylinder lock.
Remove the brush cover.
Remove the bolts securing the brush.
