4Operation
4.1Basic information
WARNING
Risk of injury due to ejected parts!
The max. speed of rotation of the machine/automated
system must be reduced when using long, projecting or
heavy tools and with extensions.
WARNING
Risk of injury and material damage due to the expansion
sleeve bursting!
If not used as intended, the expansion sleeve may burst. This
can cause metal shards and oil to be ejected from the
product under high pressure, resulting in serious injury.
•Never heat the product in heat shrink devices; only
perform a tool change using the integrated clamping
screw.
•Do not exceed the specified operating temperature.
WARNING
Risk of injury due to hot surfaces!
Touching hot surfaces can cause burns.
•Before carrying out any work on the product, make sure
that all surfaces have cooled down to the ambient
temperature.
•Wear personal protective equipment, particularly
protective gloves.
CAUTION
Risk of injury from tools with sharp edges!
Sharp edges on tools can cause cuts.
•Wear protective gloves when assembling the tool.
NOTICE
Material damage due to burrs and dirt!
•The tool must be free of burrs and dirt at the shank.
NOTICE
Material damage due to incorrect minimum clamping
depth!
Too small a clamping depth of the tool leads to a loss of
accuracy and torque on the product.
•Observe the minimum clamping depth of the tool.
NOTICE
Potential impairment of the clamping function and damage
to the product!
If the product is not used as intended, the clamping function
may be impaired or the product may get damaged.
•Only operate the clamping screw by hand.
•Do not exceed the max. unclamping temperature when
unclamping the product.

All repair work may only be performed by SCHUNK!
5.1Cleaning the clamping bore
Clean the clamping bore during every tool change with a
cleaning agent containing solvents and a cleaning brush.
5.2Checking the clamping force
Check the clamping force before initial use, after approx. 100
tool changes and at least every 3 months.
1. Unclamp the product by loosening the clamping screw.
NOTE: The clamping screw is not secured against falling
out!
2. Insert the test shaft to the minimum clamping depth.
3. Screw the clamping screw in by hand until it reaches the
stop. Observe the maximum specified tightening
torque }Chap.3.
4. The clamping force is no longer sufficient if the test shaft
can be pulled out of the product with little effort using two
fingers.
In this case, send the product to SCHUNK for inspection.
5.3Lubricating the clamping screw
CAUTION
Allergic reactions if lubricating grease comes into contact
with the skin.
•Wear protective gloves to lubricate the clamping screw.
It is necessary to adapt the cleaning and lubrication of the
clamping screw to the ambient conditions. Especially in the
case of high clamping frequencies, high operating
temperatures, and abrasive dirt or dust. For optimum
lubrication of the clamping screw, we recommend copper
paste MOLYKOTE CU 7439. (100 g tube, ID 9247204).
1. Unscrew the clamping screw from the product.
IMPORTANT!The actuating piston underneath is not
secured against falling out and must not be removed!
2. Clean the clamping screw as well as the actuating thread
and check for damage to the thread flanks. Replace if
necessary.
3. Lubricate the clamping screw and actuating thread.
4. Screw the clamping screw into the product.
5. Check the clamping force }Chap.5.2.
5.4Storage
– Lightly oil the entire surface of the product.
– Only store the product in an unclamped state and protected
against corrosion.
– Store the product in a suitable transport container.
– Protect the product from excessive temperature fluctuations.
NOTE: Before recommissioning, clean the product and check
for damage, functionality and tightness!
6Disposal
– Follow local regulations on dispatching product components
