Note: Ensure functionality.
u
Never operate the HF spindle without a clamped tool shank.
If no tool shank is clamped:
q
The clamping system is damaged by the centrifugal forces.
q
The clamping system is shifted.

10.1
Clockwise
Sample illustration:
Direction of rotation indication
The HF spindle clamping system is designed for clockwise rotation.
Ü
Only use tools with the correct direction of rotation for the HF spindle.
Ü
Only use tool mounts with the correct HF spindle direction of rotation.

pneumatic taper change
DANGER: Due to flying parts.
The taper cleaning could build up air pressure in the hollow shank taper dur-
ing the tool taper change. This air pressure flings out the hollow shank taper
in the case of sudden release.
u
Ensure that the ventilation hole of the shaft is open.
