Operating
If you have not read the safety instruc- tions in this manual, do not operate the nailer.
Before you operate your nailer, place one drop of the included oil into the quick con- nect fitting where the nailer connects to the air supply.
To operate your nailer:
1.Connect the nailer to the air supply.
2.To test for proper nail penetration, hold the nailer perpendicular to the surface of a piece of clean scrap wood that is thick enough for the length of nails you have loaded.
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 nail in case of deflec- tion.
Deflection is caused when grain irregu- larities, 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 4.

Besides damaging your workpiece, deflection can cause injury if your free hand is securing the workpiece in the location that the nail deflects.
5.Pull the trigger. If the nail drives into the wood far enough, continue with your
intended operations. If the nail goes too far or not far enough, adjust the depth adjustment knob described in the Adjusting Depth section.
Adjusting Depth
The Model T20644 features a knurled adjustment knob (Figure 5) for setting the nail depth into the workpiece.
Rotate this knob to adjust the workpiece. To find the correct nail penetration depth, use
