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.
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.
A depth adjustment knob is attached to
the nose for setting the nail depth.
To adjust the depth, do these steps:
1. DISCONNECT NAILER FROM THE AIR
SUPPLY!
2. Loosen the cap screw on the depth
adjustment device (Figure 6), and
move the safety nose backward
to increase depth or forward to
decrease depth.
3. Re-tighten the cap screw.

4. Connect nailer to the air supply

procedure if necessary until the nail
depth is satisfactory.
