25. How do I adjust the depth of drive of my Grex pinner?

Due to the kind of work folks use pinners for, a depth of drive knob is not practical. Your Grex pinner arrives from the factory with a set depth of about 10 to 20 thousandths of an inch. This depth is primarily a function of the distance to which the driver blade extends out of the pinner when shooting. Depending on the hardness of your workpiece, a greater depth of set may be possible by increasing the operating air pressure.

If you wish for an even greater depth of set, you can do the following. DISCLAIMER. This modification is irreversible and if done improperly may result in tool damage. Proceed with caution and only attempt if you are highly experienced with pneumatic nailer operation and maintenance.

Using a file, NOT A GRINDER, take a couple of passes over the tip of the pinner nose, from side to side, not front to back. Then try to take a shot into a piece of scrap. If this depth is suitable, you are done, if not, repeat. Do not take so much off the tip of the tool that the driver blade comes out by more than 1/32 of an inch. This modification may potentially compromise the longevity of your driver.
