Warning:
Intended use
Reasonably foreseeable misuse
- HD chuck for clamping rotationally symmetrical tools.
- For work in industrial environments.
- Observe minimum clamping depth.
- If using custom designs, observe the specifications in the applicable drawings.
Reasonably foreseeable misuse
- Do not use in explosion hazard areas.
- Not for use in areas where high concentrations of dust, flammable gases, vapours or solvents are present.
- Do not combine extensions.
- Not to be used for workpiece clamping.
- Do not heat with a shrink-fit unit.
