OPERATION
SETTING SCREW LENGTH
See Figure 5, page 11.
The adjustable nosepiece allows the tool to automatically
drive screws to preset depths.
To make preset depth adjustments:
 Unplug the screwdriver.
 Remove the nosepiece screw by turning counterclock-
wise.
NOTE: You may use the supplied hex key to loosen and
tighten screw if desired.
 Slide nosepiece into the slot along the side of the feed
housing.
 Align marks on the adjustable nosepiece with edge of
feed housing for proper screw length.
 Reinsert and tighten the nosepiece screw by turning in
clockwise direction.
 Make sure the nosepiece is securely attached before
operating.
CHANGING THE NOSEPIECE
See Figure 5, page 11.
Two nosepieces are included, one for wood and one for
drywall. The nosepiece can be removed and changed out
by following the instructions in Setting Screw Length.
LOADING COLLATED SCREWS
See Figures 6 - 7, page 11.
Before loading the screwdriver, check to be sure tops of
screws are resting on top of collated tape material as shown
in figure 6.
To load screw strip:
 Unplug the screwdriver.
 Adjust nosepiece to correct screw length. Follow the
instructions in Setting Screw Length.
 Unsnap and rotate bottom of screw guard to access
screw strip guide.
 Feed screw strip into the strip guide.
 Move the screw strip forward into the feed housing until
the second empty hole lines up with the bit. This will allow
the screws to advance properly when the nosepiece is
depressed.
 Snap the screw guard back in place.
To remove screw strip:
 Unplug the screwdriver.
 Pull screw strip through from the top of the feed housing.
DEPTH OF DRIVE ADJUSTMENT
See Figure 8, page 11.
The depth of drive adjustment thumbwheel allows fine tuning
of the countersink. Begin each new job by driving several
test screws in scrap material to check and adjust for proper
countersink.
The screwdriver has a depth-sensing clutch. When the
screw is countersunk to the preset depth, it automatically
disengages and makes a clicking or racheting sound. This
is normal and signals completion of the drive.
DRIVING SCREWS
See Figure 9, page 11.
 Check the adjustable nosepiece for proper screw length
setting.
 Check the direction of rotation selector for correct setting
(forward or reverse).
 Secure the workpiece. Use clamps if necessary.
 Plug the screwdriver into power supply source.
 Hold the screwdriver firmly. For best results, keep the
screwdriver at a right angle to the work surface.
 Depress the switch trigger to start the screwdriver. Press
the nosepiece, with constant force, against the work
surface. Do not remove the tool from the work surface
until the clutch disengages and the bit stops rotating,
signaling a fully driven screw.
 Check for proper countersink. Adjust using depth of drive
adjustment thumbwheel if necessary.
 You may keep the switch trigger depressed so the next
screw will be automatically fed into place when the tool
is depressed against the work surface.
