If the blade insert cannot be inserted by hand,
it is advisable to use lubricant and a soft-face
hammer. (see Fig. 4 - Inserting the new blade
insert)
After 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)
