ASSEMBLY AND ADJUSTMENTS

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from power
source before making any adjustments or removing/
installing attachments or accessories. Be sure the
trigger switch is in the OFF position. An accidental start-up
can cause injury.
Fitting and Removing 1/4" Hex Drive
Accessories
Your D WALT screwdriver has a 1/4" hexagonal drive system. The
e
drive accessory is retained in the holder by a ball and a spring
which engages in a groove in the accessory shank.

1. Remove the collar 4 by pulling it forward.
2. To insert the accessory
holder until it snaps in place. Tap it lightly if required.

3. To remove the accessory, pull it out of the holder using a
pair of pliers.
4. Reinstall the collar 4 by aligning the ribs
the collar 4 with the grooves
snap the collar in place.

Replacing the Bit Tip (Fig. B)
Simply pull out the bit tip 11
Driving Depth (Fig. C)
DW274/DW274KN/DW275KN
The depth sensitive feature offers the following advantages:
• The selected driving depth is repeatable for
structural integrity.
• Screws with sealing washers are driven correctly so that no
leaks occur.
Setting the Driving depth
The driving depth is determined by the position of the depth
locator 5 in relation to the bit or socket.The symbols on the
collar 4 indicate how to set the driving depth.
• Turn the collar 4 clockwise to increase the driving depth.
• Turn the collar 4 counterclockwise to decrease the
driving depth.
Versa Clutch® Units
DW268 (Fig. A2)
External adjustment of all Versa Clutch® units for a wide range of
fastener sizes is fast and easy, as follows:
1. Pull forward, then rotate collar in increase direction
(stamped on adjustment collar) to increase the amount of
clutch engagement and torque output.
20
, e.g., a bit holder, push it into the
12
9 on the inside of
10 in the clutch housing and
to the front and hold it.
. A pair of pliers may be required.
2. Maximum rotation of the collar in the increase direction
results in full clutch engagement and maximum torque
output and fastener capacity. Collar and adjustable stop will
not screw off clutch housing.
3. Test drive a fastener into a scrap piece to check proper
fastener seating. It is normal after a period of use to
require a slightly different collar setting due to wear on the
clutch faces.
nOtE: With Versa Clutch®, the operator has the ability to
"override" clutch ratchet if a fastener hits a wood knot, variable
hardness in steel work pieces or incorrect pilot holes. Increased
operator pressure will usually cause the clutches to pick-up
and continue to seat the fastener. Further, a quick twist of the
collar will change the clutch setting to overcome most driving
difficulties and will provide for immediate change in torque
output giving the operator the option to drive a wide range of
fastener sizes.
Forward/Reverse Switch (Fig. D)

WARNING: Always wait until the motor has come to
a complete standstill before changing the direction
of rotation.
Select the forward or reverse rotation by moving the forward/
reverse switch in the direction indicated by the arrows.

OPERATION
Instructions for Use

WARNING: Always observe the safety instructions and
applicable regulations.

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from power
source before making any adjustments or removing/
installing attachments or accessories. Be sure the
trigger switch is in the OFF position. An accidental start-up
can cause injury.
Proper Hand Position (Fig. E)

WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position as shown.

WARNING: To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of a
sudden reaction.
Proper hand position requires one hand on the main handle
as shown.
For best results, hold the screwdriver with the hand directly in
line with the fastener and press the variable speed switch with
the last one or two fingers of the hand, as shown. This reduces
the chance of the screw slipping from the drive accessory when
pressure is applied.
Screwdriving (Fig. A1)
1. Select the appropriate bit for the screw (or nut) to be driven.
2. Select forward or reverse rotation as described above.
3. To run the tool, press the variable speed switch
pressure exerted on the variable speed switch determines
the tool speed.
