Keyless Chuck (fig. 1, 6–8)
DWD024S, DWD024S-XE, DWD025S-XE
The DWD024S, DWD024S-XE and DWD025S-XE feature
a keyless chuck (d) for greater convenience.
TO INSERT A DRILL BIT OR OTHER ACCESSORY
1. Grasp the rear half of the chuck with one hand
and use your other hand to rotate the front half
counterclockwise, as shown in Figure 6. Rotate far
enough so that the chuck opens sufficiently to
accept the desired accessory.
2. Insert the bit or other accessory about 19 mm (3/4")
into the chuck and tighten securely by holding the
rear half of the chuck and rotating the front portion
in the clockwise direction. When the chuck is nearly
tightened, you will hear a clicking sound. After 4–6
clicks, the chuck is securely tightened around the
accessory.
3. To release the accessory, repeat step 1 listed above.
WARNING: Do not attempt to tighten drill
bits (or any other accessory) by gripping the
front part of the chuck and turning the tool
on. Damage to the chuck and personal injury
may result.
KEYLESS CHUCK REMOVAL (FIG. 7)
Tighten the chuck around the shorter end of a hex key
(not supplied). Using a soft hammer or piece of wood,
strike the longer end in the counterclockwise direction.
This will loosen the chuck so that it can be unscrewed
by hand.
KEYLESS CHUCK INSTALLATION (FIG. 8)
Screw the chuck on by hand as far as it will go. Tighten
the chuck around the shorter end of a hex key (not
supplied) and strike the longer end in the clockwise
direction with a soft hammer.
OPERATION
Instructions for Use
WARNING: Always observe the safety
instructions and applicable regulations.
WARNING: To reduce the risk of injury,
turn unit off and disconnect tool from
power source before installing and
removing accessories, before adjusting
or changing set-ups or when making
repairs. Be sure the trigger switch is in
the OFF position. An accidental start-up
can cause injury.
Trigger Switch (fig. 1)
To start the drill, depress the trigger switch; to stop the
drill, release the trigger switch.
NOTE: Use lower speeds for starting holes without
a center punch, drilling in metal or plastics, driving
screws or drilling ceramics. Higher speeds are better
for drilling wood and composition boards and using
abrasive and polishing accessories.
VARIABLE SPEED
A variable speed trigger switch (a) permits speed
control—the farther the trigger is depressed, the higher
the speed of the drill.
For continuous operation, press and hold the variable
speed switch, press the lock-on button (b), then release
the switch.
To stop continuous operation, press the switch briefly
and release it. Always switch the tool off when work is
finished and before unplugging.
Proper Hand Position (fig. 9)
WARNING: To reduce the risk of serious
personal injury, ALWAYS use proper hand
position as shown in figure 9.
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 (j), with the other hand on the side handle (g).
Drilling
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.
WARNING: To reduce the risk of personal
injury, ALWAYS ensure workpiece is anchored
or clamped firmly. If drilling thin material, use
a wood "back-up" block to prevent damage to
the material.
1. Use sharp drill bits only. For WOOD, use the low
speed setting and twist drill bits, spade bits, power
auger bits, or hole saws. For METAL, use the low
speed setting and steel twist drill bits or hole saws.
For MASONRY, such as brick, cement, cinder block,
etc., use carbide-tipped bits rated for percussion
drilling.
2. Always apply pressure in a straight line with the bit.
Use enough pressure to keep drill biting, but do not
push hard enough to stall the motor or deflect the
bit.
3. Hold tool firmly with both hands to control the
twisting action of the drill.
