12. SCRAPPING INFORMATION
- If the jack is no longer to be used, it should be made unserviceable by removing the power connection plug.
- If the jack is to be scrapped, it should be considered as special waste and thus disposed of in accordance with current
national laws.
13. PERIODIC TESTS AND REGISTER
A General Visual Inspection should be performed on a DAILY basis to check the following:
• The general state of the jack and whether any parts are damaged or missing;
• The legibility of the tags attached to the jack, in order to replace any illegible tags;
• Leaks in the hydraulic circuit. A slight dampening effect is admitted, provided that no drops form.
