Work on and with the power chuck may only be carried out by qualified oper-

2.6 General Dangers
When using the device there is a special potential of residual risks
▪ during assembly and set-up work,
▪ during operation and
▪ during maintenance and service work.
This potential risk cannot be completely eliminated considering the func-
tional availability of the operating manual. Therefore, all individual regula-
tions of this operating manual are to be observed.
2.6.1 Dangers due to Flying Parts
During operation, the connection between the clamped workpiece and the
power chuck DURO-A may become loose due to mechanical failure (e.g. due
to defective parts) or incorrect operation (e.g. excessive speed). The work-
piece may then fly out and cause serious crushing and impact injuries.
To prevent cutting and crushing injuries, ensure perfect functioning of the
power chuck DURO-A before each operation. Also ensure that unauthorised
persons cannot rotate the power chuck DURO-A unintentionally.
▪ The maximum permissible speed is only permitted at maximum
clamping force.
▪ The power chuck only reaches the maximum specified clamping force
total when the maximum actuation force is applied.
▪ The clamping force must be checked regularly .
▪ Operation is only permitted with an effective safety guard.
The maximum torque which can be transmitted by the power chuck to the
workpiece depends on the technical design of the top jaws.
