4. Replacing a shock absorber
The shock absorbers have a limited life. Therefore, they should be checked regularly (every 2
million cycles) to ensure that they are functioning properly. The shock absorber is operating
correctly if the unit moves gently into the end positions. The shock absorbers are specially in-
spected and available only from SCHUNK.
(1) Loosen the screws (item 102).
(2) Remove the cover (Item 12).
(3) Remove the safety rings (Item 50) from the pistons.
(4) Pull out the shock absorbers (item 54) and remove all fitting disks from the hole.
(5) Insert the new shock absorbers. Note the shock absorber projection
(see table on page 2).
(6) Place fitting disks under the safety rings so that there is no play.
(7) Mount the stop cover.
(8) Screw the stop cover securely.
(9) Check the shock absorption. If necessary, adjust the shock absorption
(see Chapter 3).
