| “Notes: 1. Install the vibration-isolation platform on an independent isolated foundation; otherwise isolation performance may be reduced. 2. If the product remains in one position for an extended period, use a level to readjust the worktop. 3. Do not clean the worktop with acidic liquids, which may damage its surface quality.” |
