•The module may be used only within its defined application pa-
rameters.
•Ensure that the environment is clean. Observe the lubrication
intervals (10.2, Page 20).
•Ensure that the environment is free of splashing water and va-
pors, and also of abrasive dust and process dust. This does not
apply to modules designed especially for unclean environ-
ments.

Adjusting the end positions
The parts listed below are included within the scope of delivery of
every rotary module for angle of rotation fine adjustment and ad-
justment of the end position dampening to the mass moment of
inertia occurring in operation.
•Counter nut (10)
•Stop coupling (13)
•Rod (14)
•Shock absorber (22)
•Counter nut (23)

Angle of rotation fine adjustment
1 Release counter nut (10).
2 By twisting the stop coupling (13) with the rod (14) and shock
absorber (22) that are integrated in it, the angle of rotation in
both end positions can be set by ±5° from the nominal angle
of rotation. The nominal rotation angle has to be specified for
the order and can be selected without steps between 5° and
180°. Standard angles are 90° and 180°.
3 Tighten the stop coupling again with the counter nut.
Dampening adjustment
NOTICE
Use the shock absorber!
Operation without the shock absorber included within the scope
of delivery is not permitted.
•Observe the maximum mass moment of inertia (☞catalog da-
ta).
•Adjust the dampening at the mass moment of inertia.
The desired angle of rotation has been set (7.3.1, Page 15).
1 Release counter nut (23).
2 By turning the shock absorber (22) in and out, the stroke of
the shock absorber (and therefore the shock absorber charac-
teristic curve) can be adjusted to the mass moment of inertia
occurring in operation. The previously adjusted angle of rota-
tion is not influenced by this.
3 Tighten the absorber again with the counter nut.

Start-up
•Check the technical specifications (6, Page 11).
•Check the permissible loading specifications (see catalog).
•Do not use the module until trouble-free operation has been
checked taking all permissible operating parameters into ac-
count.
•Set the speed of the movement in such a way that the permit-
ted swiveling time is not exceeded. Use the "Gemotec Toolbox"
program for calculation (www.schunk.com).
•The movement speed is ideally regulated via throttle check
valves (7.2, Page 13). The speed is always set so that it starts
at a low speed and increases to a higher speed until the desired
operating speed has been reached.
•Operate the device in such a way that the permissible cycle
number per minute is not exceeded. Use the "Gemotec Tool-
box" program for calculation (www.schunk.com).

Maintenance and care
Shock absorber
NOTICE
Serious mechanical damage due to failure of the shock absor-
bers.
The shock absorbers have a limited service life span. A shock ab-
sorber failure can lead to serious mechanical damage; for this
reason, they must be checked regularly for proper function. The
shock absorber is working correctly if the device reaches its end
position swiftly without any mechanical impact.
Overloading of the unit or exceeding the permitted swivel speed
can lead to drastic reduction of the service life.
•Determine the swiveling times and the permitted stroke fre-
quency with "Gemotec Toolbox".
•Regularly check the shock absorber.
•Observe the recommended maintenance intervals.
Maintenance and lubrication intervals
NOTICE
At ambient tempertature above 60°C the lubricans
cure out faster
•Interval decrease accordingly.
