3.Depress the safety yoke mechanism on 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 staple in case of deflection.
Deflection is caused when grain irregularities, knots or foreign objects inside the wood cause the staple to change its path, resulting in the staple 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 staple deflects.
Figure 5. Example of staple deflection.
5.Pull the trigger.
—If the staple drove into the wood far enough, continue with your intended operations.
—If the staple either went too far or not far enough, then adjust the air pressure. More air pressure will make the staple go deeper and less air pressure will decrease the staple penetration.
