Question about Bosch Home & Garden Home and Garden PTK 14 EDT Ele

Type 53 (clamp) 11.4mm x 6-14mm), Type 48 (nail) 14mm

Thank you Mr Britt for your valued reply. I still have many packs of Black&Decker Extra hard staal A 5948 in the workshop, they were for another machine, unfortunately there is no type description on the pack for the staples, except for Nieten Extra hard staal and a pictured machine with the description DN 418 which looks similar to the Bosch, the width would be correct from the staples with 11.4mm, the 8 mm also. I am not sure if I can use up the staples from the old Black&Decker for the new Bosch PTK 14 EDT or if I can only use Bosch staples because otherwise the machine could be damaged. Thanks for a tip.
