If the blade insert cannot be inserted by hand,
it is advisable to use lubricant and a so-face
hammer. (see Fig. 4 - Inserng the new blade
insert)
Aer the new blade insert has been fully inserted,
the shears are turned and the tensioning pin
is driven in again from the rear.
(see Figure 5 - Driving in the tensioning pin).
Make sure that the tensioning pin is fully driven
in again with the punch. (see Fig. 6 - Fully
hammering in the tensioning pin)
