First check to make sure grease or oil has not been transferred from the user’s shoe or pant leg to the floor. The user may have rubbed their feet across the grease applied to the cylinder and transferred it to another surface.
This issue could be caused by one of the following:
•    The seal on the cylinder has broken.
•    The chair's hubliner has come loose causing the cylinder to become misaligned.
•    If the chair is new, there has been too much grease applied to the hubliner in the base.
•    To resolve this issue with your chair, please locate the serial number on the sticker located on the underside of the seat and contact your purchasing dealer.
