Load bearing bolts
Only greased load-bearing bolts ensure a uniform swing-out of the buckets
and, therefore, the smooth operation of the centrifuge. Load-bearing bolts
that are insufficiently greased may cause the centrifuge to stop due to an
imbalance.
• Clean the load-bearing bolts and bucket groove in order to remove the
old grease.
• Apply a small amount of heavy-duty grease for load-bearing bolts (ref.
no. 71401, see the following picture) to both load-bearing bolts of a
bucket.

• Install the bucket and swing it manually back and forth once in order to
distribute the grease.
• Repeat this process with all the other buckets.
