3 OPE ATION
No rotation without clamped tool!
Only use technically perfect tools!
3.1 TOOL INSE TING
Do not insert tool into the spindle taper
when rotating!
The tool has to be inserted all the way
to the plane surface of the clamping
cone to prevent misclamping!
Our recommendation for the
concentricity tolerance for tool
changing as well as the maximum
force on the plane surface on the
clamping cone is shown in the table
below:
standard size A63 / B80 / E63 / F80
concentricity (øG) [mm] 0,8
tool changer force max. [kN] 3,6

PRODUCT INFORMATION

3.2 OPE ATING CONDITIONS
Avoid additional stress contributed to force from brackets or any other connection and
or support, proximity switches
impact loads < 25 g
the spring must be protected against corrosive media and dirt exposure
the tool interface must be free of chips and substantial cooling lubricant residue
allowable temperature 10° C (on the inside of the spindle)
3.3 INTE N COOLING SUPPLY
Because of possible damage at the coolant tube interface (tube/seal) we recommend
drainage holes in the tool interface area
during installation of tool:
pressure in clamp chamber p < 0,5 bar
In order to minimize wear, the coolant tube at the interface of the gripper assembly
and tool should be shaped as follows:
minimum and easy going and angular flexing (per ISO 12164-1)
ground
Operation with coolant is only permitted if free flow is guaranteed. Therefore, you
must only use tool holders with coolant tubes and tools with coolant thru holes.
Otherwise, it is possible that the spindle gets flooded or the seals are damaged by the
pressure spikes.

3.4 COOLANT
Guidelines and technical specifications for the coolant use in the machine:
Coolant use must conform to the current regulations of the legislation and the
professional association.
Our products are to the greatest possible extent protected by the materials used or by
means of a passivated surface against corrosion and therefore suited for use with water.
The rate of corrosion is strongly dependent on the contents of the media
(e.g. chlorine is very much increasing the rate of corrosion), as well as the environment
in which the products are being operated (e.g. the difference in electrical potential
between rotor and stator in spindles).
Suitable protective measures such as the utilization of corrosion inhibitors will extend
the service life in every way.
Furthermore, you must only use coolants which conform with the specs listed on the
table below.
Parameter / test procedure Limited values
Corrosion protection according
to DIN 51360 section 2
No corrosion after 2 hours
Elastomer compatibility No change of the shore hardness and/or the
elongation
OTT-JAKOB applies FKM (VITON®)
Nonferrous metal compatibility No corrosion on copper, brass and aluminum parts
Glue residue after slow
evaporation at 50 degrees
Non sticky! No residue! Easily removable.
3.5 GENE AL
Recommendation: install a limit switch for the drawbar
Follow maintenance intervals!

4 MAINTENANCE
4.1 MAINTENANCE INTE VALS
To guarantee the function of the power drawbar the following maintenance intervals must be
adhered to.
Every wee
Check the packing ring in the clamping unit (visual check)
Check the clamping unit if it is polluted or damaged; is it sufficient greased? (visual check)
Please see below:
The regrease cycle depends on the loss of lubrication of the clamping unit.
Cause for the loss of lubrication:
Seal in the clamping cone is defective
Type of medium used can desolve grease
Cleaning spray from outside directly on the clamping unit etc
Regrease clamping unit → # 4.2 // 10
Every six month or after 200.000 tool changes at the latest
In unclamped position: Check dimension gauge E.M.
counter through a clamped tool again.
Test Pull-in-force (we recommend:use POWER-CHECK ):
If the pull-in-force is smaller than 70% of the nominal value, following procedures have to be
performed in the following sequence:
regrease ( → # 4.2 // 10 ) and test pull-in force again
exchange clamping unit and test again
exchange drawbar completely
Every year or after 500.000 tool changes at the latest
Exchange the packing ring → # 4.3 // 11

Note: take only grease of one company; do not mix the grease!
Regrease in assembled condition
If very dirty: take clamping unit out and clean.
Then grease clamping unit and reassemble → # 2 // 4

4.3 EXCHANGE OF THE LIP SEAL
For dismounting the lip seal it is not necessary to take away the ring. Only when the ring is damaged
it must be exchanged.
Take away the damaged lip seal with a
hook or pliers
Compress the lip ring and build in; look for
the build in position
press the seal with a blunt object against
the lining
take a mandrel to bring it in the finaly
position
4.4 B EAK OF A G IPPE SEGMENT
If one of the gripper segments should break, the complete clamping unit needs to be replaced!
