4.2.2 Inserting the workpiece and clamping it firmly
DANGER!
The hydraulic vice closes with high force. Keep body parts away from the danger area.
CAUTION!
If sawing is carried out without using the workpiece clamp or with insufficient clamping
effect, the workpiece may be ejected, which can lead to injuries. The workpiece clamping
must be used without exception. If the clamp cannot fix the workpiece sufficiently, the
machine must not be used.
CAUTION!
Do not wear loose clothing such as an open work coat when switching on the metal
band saw. Observe the safety instructions.
ATTENTION!
Support long workpieces before pushing the piece to be cut into the quick-action vice.
