Note:
Three points to be aware of during the video:
- To unclip the hose clamp, twist the clip ends in opposite directions
- Note the point in the video when the hose end is covered to prevent hydraulic fluid from draining
- The fluid height in the reservoir will change depending on the height of the table. For the final fill, the table is raised to full height—ensure the reservoir is only half-full
Extract air bubbles from the hydraulic lines. Refer to the Extract Air Bubbles video on the MR Service Documentation Website.
