Monitoring the expansion rate

A control of the clamping force should be done before the first use, after
appr. 100 tool changes and every 3 months at the latest. During monitoring the expansion
rate the ambient temperature should lie between 20 °C to 25 °C.
For this purpose, a corresponding test shaft (accessory) should be inserted at least to the
minimum clamping depth into the Hydraulic Expansion Toolholder. If the test shaft can
not be inserted, unscrew the clamping screw a little bit more by turning it to the left.
