    In order to make the friction stay in the best working condition or longer working life, we need to maintain it at terms:
    Cleanning:
    The surface of friction stay should be cleared often, but not use the strongly corrosive solvent.
    Fixing the bolt:
    Please use the relative tool to fix the loosed screw.
    Lubrication:
    All moving and fricting parts of the friction stay , should use lubricationg oil or other lubricant , only the place of the sliding plate and track is not included , because of their own-lubrication.
