Procedure

Do Table top height adjustment.
If necessary, add hydraulic oil to the reservoir. (Level should be 6.5 to 12.5 mm above the full line when the table is at its lowest position.)
Inspect the down valve linkage adjustment according to the illustration below. Obtain the desired tolerance between the down valve linkage and bracket by adjusting the two set screws on the bracket.
