Operation - DeWalt DWEN302 Handbuch

ENGLISH
To release the bit, turn the chuck counterclockwise
in just one hole, then loosen the chuck by hand.
REMOVAL OF KEYED CHUCK (FIG. 4)
Tighten the chuck around the shorter end of a hex
key. Using a soft hammer, strike the key sharply in
the counterclockwise direction when viewed from
the front of the tool. This will loosen the chuck so
that it can be removed by hand.
KEYED CHUCK INSTALLATION (FIG. 5)
Screw the chuck on by hand as far as it will go.
Insert the shorter end of a hex key and strike it in the
clockwise direction with a soft hammer.

OPERATION

Instructions for Use
WARNING: Always observe the safety
instructions and applicable regulations.
Trigger Switch (fi g. 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 (fi g. 6)
WARNING: To reduce the risk of
serious personal injury, ALWAYS
use proper hand position as shown
in figure 6.
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.
CAUTION: Drill may stall if overloaded
causing a sudden twist. Always expect
the stall. Grip the drill firmly to control
the twisting action and avoid injury.
4. IF DRILL STALLS, it is usually because
it is being overloaded or improperly used.
RELEASE TRIGGER IMMEDIATELY, remove
drill bit from work, and determine cause of
stalling. DO NOT CLICK TRIGGER ON
AND OFF IN AN ATTEMPT TO START A
STALLED DRILL — THIS CAN DAMAGE
THE DRILL.
5. To minimize stalling or breaking through the
material, reduce pressure on drill and ease the
bit through the last fractional part of the hole.
6. Keep the motor running when pulling the bit
back out of a drilled hole. This will help prevent
jamming.
7. With variable speed drills there is no need to
center punch the point to be drilled. Use a
slow speed to start the hole and accelerate by
squeezing the trigger harder when the hole is
deep enough to drill without the bit skipping out.
