Design and description
4.2 Functional description
This product clamps hydraulically by means of manual actuation.
The piston with stroke limitation is actuated via a clamping screw.
To achieve the full clamping force, the clamping screw must be
screwed in until it reaches the stop. The stroke limitation protects
the product against over-expansion.
The volume of oil that is squeezed out of the piston chamber is
pressed in measured amounts against the thin-walled expansion
sleeve. The resulting internal pressure presses radially against the
thin-walled expansion sleeve, causing the clamping range to
expand evenly along the entire active clamping length, uniformly
central to the middle axis. The tool is clamped.
Screwing back the clamping screw causes a reduction of the
pressure in the piston chamber and the expansion chamber. The
thin-walled expansion sleeve then returns radially to its exact
home position. The tool can be removed.
The electronics built into the product allows the detection of
vibrations during machining.
Using a compatible tablet and the iTENDO² app, the detected
vibrations can be displayed and recorded. The data is transmitted
via a wireless connection between the product and the tablet.

6.2 Clamping tool
The product must be unclamped when loading the tool. Initial
tension inhibits loading and can damage the expansion sleeve.
IMPORTANT!The tools to be clamped must be deburred at the
surfaces that come into contact with the product, may not have
sharp contours and must be free of oil, grease and dirt.
When clamping the tool, the following points must be taken into
account:
• The clamping screw may only be actuated by hand.
• Do not combine multiple extensions (e.g. TENDO SVL).
• The product may not be clamped without a tool above 25°C.
• Only clamp approved tool shank types }3.4 [/13].
For clamping, proceed as follows:
1. Observe the technical data }3 [/12] and the marking on the
product.
2. Make sure that the product is in an unclamped state.
3. Clean clamping surfaces.
4. The tool length can be adjusted by screwing the length-setting
screw in or out. Observe the adjustment travel of the length-
setting screw }3.3 [/13]. NOTE:The length-setting screw is
not available in all variants of the product.
5. Insert the tool into the product in the correct position without
exerting too much force. CAUTION! The minimum clamping
depth }3 [/12] must not be undershot!
6. Screw the clamping screw in by hand until it reaches the stop.
Observe the maximum specified tightening torque }3 [/12].
7. Check that the tool is firmly in place.
8. Mount the product }5 [/16].
IMPORTANT!Safe clamping of the tool is only achieved when the
clamping screw is screwed in until it reaches the stop!
