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.
 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.
OPERATION
 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.
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 WORKLIGHT
See Figure 10, page 13.
Press LED worklight grip switch while firmly holding tool
during operation.
DIAGNOSTIC FEEDBACK
The LED worklight provides feedback to indicate whether
the battery pack is charged sufficiently and/or if the tool is
functioning properly.
If the light goes out on your nailer, the unit has timed out for
your protection. Lift tool from the workpiece and release trig-
ger to reactivate the nailer before beginning next drive cycle.
If LED worklight is flashing, install fully charged battery.
If light continues to flash, see Troubleshooting section for
more information.
REMOVING NAILS FROM THE TOOL
See Figure 11, page 13.
WARNING:
Remove the battery pack before removing nails or clear-
ing a jammed nail. Failure to do so could result in serious
personal injury.
 Remove battery pack from the tool.
 To remove a strip of nails from the tool, depress the maga-
zine release button located at the rear of the magazine
and slide the magazine open.
 Remove nails.
 Close the magazine.
REMOVING A JAMMED BRAD NAIL
See Figure 12, page 13.
WARNING:
Remove the battery pack from the tool before clearing a
jammed fastener. Failure to do so could result in serious
personal injury.
