Replacing a shock absorber
The shock absorbers have a limited life depending on the load. The
shock absorbers are specially adjusted and can only be obtained
from SCHUNK.
1 Test the shock absorber for function regularly.
The shock absorber functions correctly when the module
moves smoothly into the limit positions.

1 Before turning, secure the adjusting sleeves (6) with a spanner
wrench with pin (DIN 1810, form B). Should this key not be on
hand, loose the clamping screw (35) about approx. 1 turn and
remove the stop cover (8) and stop sleeve (6) together. After
replacing the shock absorber the end position must be read-
justed.
2 Remove the safety rings (50) on the pistons.
3 Pull out the shock absorber (54).
4 Remove all fitting discs out of the drill hole.
