• Tighten or push the shock
absorber 1 into the open-
ing intended for this pur-
pose until the end position
is reached.

• Fasten the shock ab-
sorber 1 with lock nut 5
or with clamping ele-
ment 6 according to your
fitting variant.
• Note the permitted tighten-
ing torque M
A
:
– of lock nut 5
(see table).
– of clamping element 6
(see operating instructions
for the drive).
• Carry out a test run with the shock absorber 1 to make sure that the
drive does not have a hard impact on the end position.
Please note
The energy values in the table apply when the setting pin 4 is screwed in
completely, i.e. with the maximum set stroke (H
max
).
If you wish to reach the fixed defined end position with a lower drive force
(F
A
), you can reduce the stroke of the shock absorber 1
as follows:

4. Reducing the stroke H or the cushioning energy
10280d_11
• Unscrew the setting pin 4
in stages (one revolution
per step) until the defined
end position is reached with
the existing drive force (F
A
).
• Carry out a test run with the
shock absorber 1 to make
sure that the drive does not
strike hard here.
