Unscrew all four m4x8 mm bolts using a 2.5 mm hex wrench.
Carefully lift only the upper element of OCHAIN so that small parts, elastomers ad
springs will not loose their positioning.
NOTE: use one finger to hold and maintain the bottom part of OCHAIN laid on a flat
stable surface.
Whenever everything goes wrong and you find yourself with pieces around, follow
dedicated instructions video onOCHAIN Youtube channel.
Every time you open OCHAIN take the opportunity to wipe it with a clean cloth
from eventual dirt and old grease, then regrease with commercial lithium grease as
shown on maintenance video on OCHAIN Youtube channel.
Replace all four elastomers with chosen ones, placing them on the right side as shown.
