3.Depress the safety nose mechanism against your workpiece.
4.Before pulling the trigger, make sure your free hand and other body parts are positioned out of the way of a potential path of a nail in case of deflection.
Deflection is caused when grain irregularities, knots or foreign objects inside the wood cause the nail to change its path, resulting in the nail puncturing the surface of the workpiece, as shown in Figure 5.
Besides damaging your workpiece, deflection can cause injury if your free hand is securing the workpiece in the location that the nail deflects.
Figure 5. Example of nail deflection.
5.Pull the trigger.
—If the nail drove into the wood far enough, continue with your intended operations.
—If the nail either went too far or not far enough, then go to the Adjusting Depth section on this page.
Adjusting Depth
A depth adjustment knob is attached to the nose for setting the nail depth.
To adjust the depth:
1.DISCONNECT NAILER FROM THE AIR SUPPLY!
2.Rotate the adjustment knob (Figure 6) clockwise to drive the nails deeper or counterclockwise to drive the nails shallower.
