SETTING THE AIR PRESSURE
See Figure 6, page 13.
The amount of air pressure required will depend on the size
of the nail and the workpiece material.
Begin testing the depth of drive by driving a test nail into
the same type of workpiece material used for the actual job.

Remove battery pack from the tool, if installed.
 Turn air pressure dial clockwise to increase air pressure
or counterclockwise for decreased pressure.
It may be possible to achieve the desired depth with air
pressure adjustments alone. If finer adjustments are needed,
use the depth of drive adjustment on the tool.
NOTE: Under some conditions, the unit may not deliver a
nail when the air pressure dial is turned to the MAXIMUM
pressure setting. The user may need to decrease the pres-
sure setting for desired operation
DEPTH OF DRIVE ADJUSTMENT
See Figure 7, page 13.
The driving depth of the nail may be adjusted beyond air pres-
sure. It is advisable to test the depth on a scrap workpiece
to determine the required depth for the application.
To determine depth of drive, first adjust the air pressure and
drive a test nail. To achieve the desired depth, use the depth
of drive adjustment on the tool. Harder materials and longer
nails will require more force to drive the nail.

Remove battery pack from the tool, if installed.
 Turn the depth of drive adjustment left or right to change
the driving depth.
 Reinstall battery and reactivate the tool by pressing the
worklight grip switch.
 Drive a test nail after each adjustment until the desired
depth is set.
NOTE: Set depth of drive at the shallowest depth that
will meet your needs.
DRIVING BRAD NAILS
See Figures 8 - 9, page 13.
WARNING:
Never wedge or hold back the workpiece contact mecha-
nism during operation of the tool. Doing so could result
in possible serious injury.
Single sequential actuation mode:
Single sequential actuation provides the most accurate nail
placement.

Remove battery pack from the tool.
 Slide the selector to position ( ).
OPERATION
WARNING:
The nailer will not function properly if the selec-
tor is not securely seated in either position ( ) or
(
). Always assure the selector is seated properly to
avoid an unexpected nail discharge and possible serious
personal injury.
 Reinstall the battery, reactivate tool.
 Grip the tool firmly to maintain control. Position the nose
of the tool onto the work surface.
 Push the tool against the work surface to depress the
workpiece contact.
 Squeeze the trigger to drive a nail. Push the tool against
the work surface to depress the workpiece contact and
drive a nail.
NOTE: Hold trigger until drive cycle is complete.
 Always remove your finger from the trigger when the
desired number of nails has been driven.
Contact actuation mode:
Contact actuation allows very fast repetitive nail placement.

Remove battery pack from the tool.
 Slide the selector to position ( ).
 Reinstall the battery, reactivate tool.
 Grip the tool firmly to maintain control.
 Squeeze and hold the trigger. Push the tool against the
work surface to depress the workpiece contact and drive
a nail.
NOTE: Hold trigger until drive cycle is complete.

Always remove your finger from the trigger when the
desired number of nails has been driven.
NOTE: In Contact Actuation Mode, the tool may also be
operated by depressing the workpiece contact against the
surface and squeezing the trigger.
DRY-FIRE LOCKOUT
When the magazine has 0-5 nails remaining, the dry-fire
lockout feature will not allow continued operation.
To resume operation, reload the tool with nails.
LED WORKLIGHTS
See Figure 10, page 13.
Press LED worklight grip switch while firmly holding tool
during operation.
