Adjustment procedure
*1 These procedures are for making adjustment by moving the cylinder piston on the L end at its initial
position to the R end by using the deceleration controller (double-end specifications). When adjustment
is made with the single-end specifications or by moving the cylinder piston on the R end at its initial
position to the L end, skip unnecessary steps and reverse the adjustment direction as necessary.
*2 When using a cylinder with an air cushion, we recommend that you fully open the cushion needle of the
cylinder.
Please check SMC website for further details on setting and adjustment of DAS series.
