Safety and operating instructions
Checking for wear on the tool shank
Use the gauge that corresponds to the insertion
tool s shank dimension. See section "Technical data"
for correct tool shank dimensions.
>
Check if the gauge s hole (A) can be pushed down
on the insertion tool s shank, this means that the
shank is worn out and the insertion tool should
be replaced.
>
Check the length (B), that it is according to the
ordered machine type.
