Biller Safety Swap

[oneoldude]

Hi,

Just got a used Biller 48 but the seller could not help me with questions. Maybe someone here can.

What is the method to to swap the safety from left to right. It seems to have a tiny circlip on the pin that I can just see but am not sure if I should try to remove it.

Also, once the safety is removed, how do you remove the trigger mechanism? Is is as simple as knocking out the retaining pins?

Step by step instruction would be helpful.

Thanks
