23. Why aren't pins setting into the wood?

The most common reason for this problem is insufficient operating air pressure. Check the line pressure coming from your compressor. 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.

The second most common reason is not holding the tool down firmly. Make sure the nose of the tool is held firmly onto the work piece and do not let the tool bounce back when a pin is driven. Because these fasteners are so fine, even the smallest gap left between the tool nose and work surface will prevent the tool from setting the pin all the way.

If the issue is not dependent on the pin length used, then it's possible that the driver is damaged. Contact your nearest Grex Authorized Repair Center or contact us directly for assistance in helping you get your tool up and running again.
