Depth Adustment
1. Rotate adjustment collar (FIG. 5). Clockwise rotation will provide deeper
seating of screws.
2. Test drive a fastener in scrap material to determine if fastener is
correctly seating. Further adjustment may be necessary.
3. To increase depth, turn adjustment collar so that end of bit extends
further from end of locator.
4. To decrease depth, turn adjustment collar so that end of bit is closer
to the end of locator.

WALT screwdrivers have very fine depth settings; each “click” is
.007”. One complete revolution of the locator collar equals .083”
change in depth setting.
Changing Bit Holder
1. Press release buttons and remove collar from clutch housing.
2. Pull bit holder straight out with pliers if it is difficult to remove.
3. Push new bit holder into spindle until ball lock snaps in groove in
bit holder shank.
4. Align ribs on inside of depth locator with grooves in clutch housing
before snapping into place.
5. Depth locator is removable by unscrewing dust seal.
Changing Bit Tip
1. Press release buttons and remove collar from clutch housing.
(FIG. 6)
2. Use pliers to remove worn bit and install new bit tip.
Operation: Depth Sensitive Units
1. Install bit tip in bit holder or install nutsetter.
2. Adjust depth locator.
3. Check for correct rotation, start screwdriver and place screw on bit.
4. Contact work surface, applying forward pressure to drive screw until
depth locator contacts the work surface. Screwdriver will ratchet
automatically, disengaging bit from screw.
5. This depth sensitive screwdriver is suitable for driving drywall
screws when operated in high speed, and deck screws when
operated in low speed.
Tips For Driving Screws Into Decks
(Switch unit to low speed)
1. Select proper length deck screws to ensure complete anchoring into
the wood.
2. Although the screwdriver will drive drywall screws into decks, we
recommend screws specifically designed for deck assembly. Other
fasteners may not drive as well or hold as satisfactorily.
3. When using the screwdriver for the first time to drive screws into
pressure-treated lumber, practice driving some screws in scrap
material to get a “feel” and to adjust for proper seating depth. It will
be significantly easier to guide and control the screw if 1/8" pilot
holes are pre-drilled. This pre-drilling is recommended at the board
ends to avoid splitting the lumber.
4. Once a screw has started driving, do not stop the screwdriver until
the screw is seated. Keep firm pressure on the screwdriver.
Because of the high driving torque required in pressure-treated
wood, the head of the deck screw may strip if the screwdriver user
fails to maintain steady pressure on the bit.
5. More pressure can be applied to the bit if the screwdriver is gripped
by sliding the thumb and index finger along the side of the tool near
the top. Actuate the trigger with middle finger and/or fourth finger.

WALT has designed recesses along the top sides of your
screwdriver to allow for a comfortable grip.
6. Before driving deck screws, check that there is no gap between the
boards to be fastened together.
7. Avoid driving screws through knots. Screws are difficult to start into
knots. If a knot can’t be avoided, first drill a pilot hole equal in
diameter to the body diameter of the deck screw.
8. Keep a few additional bits on hand before starting any job.
