Missing changing
parts
WA NING!
Danger of injury due to missing chan-
ging parts!
When operating the clamping device without
changing parts [segmented clamping bushing,
clamping heads, work piece end-stops] there is a
higher danger of crushing injuries due to the
stroke of movable components of the clamping
device.
The clamping process may not be initiated
without assembled segmented clamping bush-
ing and/or work piece end-stop.
Parts with sharp
edges
WA NING!
isk of injury!
When screwing in individual components such as
for example work piece end-stops, threaded ad-
apters and similar devices that are equipped with
an external thread or wear caused by burrs,
there is risk of cutting.
The operation must be done only by qualified
personnel.
Wearing of gloves / [PSA] is required!
2.6 Further warnings
WA NING!
isk of injury!
Never start rotating the clamping device without
a clamped work piece.
For operation any available clamping position
must be clamped with a suitable work piece.
WA NING!
isk of injury!
Never reach for the clamping device while the
spindle is rotating. Before starting to work on the
mandrel, make sure the machine spindle cannot
be put in motion.

Segmented mandrel T812. Safety
WA NING!
isk of injury!
Falling down of the clamping device or its parts
can cause severe bruises and fractures.
The dead weight of the clamping device or its
parts can lead to high physical stress.
WA NING!
isk of injury!
By repeated reworking or wear and tear of the
clamping surfaces sharp edges and burrs may
appear and lead to severe cutting damages.
WA NING!
isk of injury!
Missing o-rings or seals may cause
severe injuries!
Due to missing / fallen out O-rings and seals
compressed air or hydraulic fluids which are un-
der high pressure may expel!
Make sure that all O-rings / seals for the hy-
draulic / pneumatic connections are available
and undamaged!
If necessary lubricate them before assembly
and/or during service.
WA NING!
Damage of clamping device!
The clamping device may be released exclusively
in the standing condition!
isk of injury!
eaking [sprayed out] hydraulic oil can cause ser-
ious injury.
Make sure that all O-rings / seals for the hy-
draulic and/or pneumatic connections are
available and undamaged

WA NING!
isk of injury!
The operating screw may be turned out and/or
thrown off!
Never put the machine adapter into rotation if
the operating system is not tightened with the
given tightening torque!
2.7 Screws
Moving parts WA NING!
Danger of injury due to screws and
stud screws being accelerated out of
the device!!
Screws and stud screws radially attached to the
product can be accelerated out of the device and
cause severe injuries.
At the product radially mounted screws and
stud screws which were loosened for assembly
and maintenance must be re-tightened with the
correct tightening torque!
The tightening torque is shown in the assembly
drawing of the product or it is engraved on the
device itself in the direct vicinity of the screw or
stud screw.
All screws or stud screws that are not marked
with a tightening torque specification are
tightened with the prescribed tightening torque
and locked [medium-strength bonding] in the
factory and should only be unscrewed after
consultation with the manufacturer. If in doubt
you must contact the manufacturer immediately
do determine the subsequent procedure.
2.8 Clamping force
The achieved clamping force can vary due to the mainten-
ance condition of the clamping device [state of lubrication
and degree of contamination] [see chapter »Mainten-
ance«].
Order Hotline +49 [0]7144. 907-333 17

Segmented mandrel T812. Safety
The clamping force must be checked at regular intervals.
This requires the use of static clamping force measuring
devices.
CAUTION!
Damages due to excessive draw and
compressive force!
An excessive draw force and/or compressive
force may damage the clamping device.
The max. draw force and compressive force
may not be exceeded.
2.9 Functionality
NOTICE!
With high contamination of the clamping device
the functionality is no longer guaranteed.
The cleaning and maintenance intervals must be
observed.

Environmental hazard due to incorrect
handling!
Incorrect handling of environmentally hazardous
substances, particularly improper disposal, can
cause significant environmental damage.
Always comply with the instructions cited below
If environmentally harmful substances should in-
advertently get into the environment, initiate
suitable measures immediately. If in doubt noti-
fy the responsible municipal authority about the
damage.
The following environmentally harmful substances are
used:
