Dead spindle drive clutch

This screwdriver is equipped with a dead spindle feature; the spindle does not turn until the fastener is pressed into the workpiece. This enables fasteners to be placed onto the drive accessory of a running screwdriver.

Electrical safety

The electric motor has been designed for one voltage only. Always check that the power supply corresponds to the voltage on the rating plate.

Your DeWALT tool is double insulated in accordance with EN 50144; therefore no earth wire is required.

Mains plug replacement (U.K. & Ireland only)

- Should your mains plug need replacing and you are competent to do this, proceed as instructed below. If you are in doubt, contact an authorized DEWALT repair agent or a qualified electrician.

- Disconnect the plug from the supply.

- Cut off the plug and dispose of it safely; a plug with bared copper conductors is dangerous if engaged in a live socket outlet.

- Only fit 13 Amperes BS1363A approved plugs fitted with the correctly rated fuse (1).

- The cable wire colours, or a letter, will be marked at the connection points of most good quality plugs. Attach the wires to their respective points in the plug (see below). Brown is for Live (L) (2) and Blue is for Neutral (N) (4).

- Before replacing the top cover of the mains plug ensure that the cable restraint (3) is holding the outer sheath of the cable firmly and that the two leads are correctly fixed at the terminal screws.

1 2 3 4

Never use a light socket.

Never connect the live (L) or neutral (N) wires to the earth pin marked E or 12

For 115 V units with a power rating exceeding 1500 W, we recommend to fit a plug to BS4343 standard.

Using an extension cable

If an extension cable is required, use an approved extension cable suitable for the power input of this tool (see technical data). The minimum conductor size is 1.5 mm^2 . When using a cable reel, always unwind the cable completely.

Also refer to the table below.

• Remove the collar (4) by pulling it forward.

• Select the required accessory (both models) and matching depth locator (5) when using a nutsetter (DW263).

• To insert the accessory (e.g. a bit holder or nutsetter) (7) push it into the holder (8) until it snaps in place. Tap it lightly if required.

• To remove the accessory pull it out of the holder using a pair of pliers.
• Reinstall the collar (4) by aligning the ribs (9) on the inside of the collar (4) with the grooves (10) in the clutch housing and snap the collar in place.

DW268K/DW269K (fig. A)

• Pull the ball retainer (5) to the front and hold it.

Replacing the bit tip (fig. B)

- Simply pull out the bit tip (11). A pair of pliers may be required.

DW263K/DW274K/DW274KN -

Setting the driving depth (fig. C)

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

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 indicate how to set the driving depth.

• Turn the collar clockwise to increase the driving depth.
• Turn the collar counterclockwise to decrease the driving depth.

DW263K - When using a nutsetter

• For screws with sealing washers, turn the adjustment collar until the end of the nutsetter is flush with the end of the depth locator.
• If required, turn the collar until the nutsetter is recessed approximately 2 mm into the depth locator.
• Also refer to the screw manufacturer's specifications for the proper sealing washer settings in different applications.

• Drive a screw into a waste piece and check the distance between the washer and the material.

• Turn the collar (4) counterclockwise or clockwise to decrease or increase the driving depth as required.

• Drive another screw and readjust the collar (4) until the desired setting is achieved.

DW263K - Replacing the depth locator (fig. D)

This model is supplied with two depth locators (5) to accommodate different bits, holders, sockets and adaptors.

• Pull the collar assembly off the tool.
• Hold the depth locator (5) and unscrew the collar (4).
• Replace the depth locator (5).
• To reassemble, proceed in reverse order.

DW268K/DW269K - Setting the torque (fig. A)

This model allows setting the torque for a wide range of screws.

• To increase the torque, turn the torque adjustment collar (4) counterclockwise.
• To decrease the torque, turn the torque adjustment collar (4) clockwise.
• Drive a screw into a waste piece and check if the screw is properly fastened.
• If the clutch ratchets unexpectedly (for example when a wood knot is encountered), simply increase the pressure on the tool.

Setting the direction of rotation (fig. E)

- Select forward or reverse rotation using the forward/reverse switch (3) (see arrows on tool).

Always wait until the motor has come to a complete standstill before changing the direction of rotation.

Instructions for use

Always observe the safety instructions and applicable regulations.

Screwdriving or nutsetting (fig. A)

• Select the appropriate bit for the screw (or nut) to be driven.
• Select forward or reverse rotation as described above.

• For nutsetting (DW263K) always use the correct depth locator (5).

• To run the tool, press the variable speed switch (1). The pressure exerted on the variable speed switch determines the tool speed.

• If necessary, press the lock-on button (2) for continuous operation and release the variable speed switch. The lock-on button works only in fullspeed, forward and reverse rotation.
• To stop the tool, release the switch.
• To stop the tool in continuous operation, press the switch briefly and release it. Always switch OFF the tool when work is finished and before unplugging.

Holding the tool (fig. F)

• 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.
• To drive the screw, place it on the bit or into the socket, press the variable speed switch and push the screw into the workpiece with a smooth, continuous motion. When the screw is seated, a buzzing sound will come from the front of the tool to indicate that the clutch has disengaged.

Various types of 1/4" hex. bits, holders, sockets and adaptors are available as an option.

Consult your dealer for further information on the appropriate accessories.
