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.
