15. How much pressure do I need to operate the Grex pinners?

Generally speaking, when working with traditional hardwoods such red oak and maple, maintain an operating air pressure of 100psi. For pin lengths longer than 1-3/8", maintain the operating air pressure at 110psi. For harder woods, your Grex pinner can be operated at a higher air pressure. Because of the precision required to drive 23 gauge pins, optimal operating air pressures are much more crucial to minimizing wear and prevent damage to your tool. Insufficient operating air pressures will prevent your tool from setting pins all the way into your work piece and also cause the driver to drive pins in at insufficient speeds. This forces the driver to “push” rather than quickly “punch” pins into the work piece resulting in excessive stress on the driver tip, which will lead to increased wear and damage. However, excessive operating air pressures may set pins too deep into your work piece, damage the work piece, over stress the tool and increase driver wear.
