Figure 6. Loosening cap screw for depth
adjustment.
The nose of the gun houses a depth adjust-
ment mechanism for setting the nail depth.
To adjust the depth:
1. DISCONNECT NAILER FROM THE
AIR SUPPLY!
2. If the nail is driven too far into the
workpiece, loosen the cap screw on
the safety nose with a 4mm wrench, as
shown in
Figure 6.
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. Pull the trigger and depress the safety
yoke mechanism on your workpiece.
4. Before pressing 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.
Adjusting Depth
3. Slide the safety nose (Figure 6) toward
the nailer body to drive nails deeper,
and away from the body to drive nails
less deep.
4. Tighten the safety nose cap screw
each time after making adjustments.
5. Connect to the air.
6. Pull the trigger and depress the safety
yoke mechanism on your workpiece to
test the depth adjustment.
