Trial Attachments
Before the actual attachment, a trial attachment
should be made on the same base material:
1. Make a trial attachment with a "green cartridge".
– If the attachment part is driven in too deeply, then
either:
– Use a larger attachment part
or
– The base material is not suitable for stud driv-
ing.
– If the attachment part protrudes, then:
2. Make a trial attachment with a "stronger yellow
cartridge".
– If the attachment part still protrudes, then:
3. Make a trial attachment with an "extra strong red
cartridge" and, if necessary, a shorter attachment
part (taking the minimum penetration depth into
consideration).
– If the attachment part still protrudes, then the
base material is not suitable for stud driving.
Caution!
Do not overload the attachment!
The strength is reduced as a result.
