Motor Brushes; Components (Fig. 1); Operation - DeWalt D21002-XE Instruction Manual

Motor Brushes

D WALT uses an advanced brush system which automatically stops the drill when the
E
brushes wear out. This prevents serious damage to the motor.

COMPONENTS (FIG. 1)

Switch (Fig. 1)
To start drill, depress trigger switch (A); to stop the drill, release trigger.
To lock trigger in the on position for continuous operation, depress trigger and push
locking button (D) up, then gently release the trigger. The locking button is for use
only when the drill is mounted in a drill press stand or otherwise held stationary.
WARNING: To reduce the risk of personal injury, be sure to release the locking
button before disconnecting the plug from the power supply. Failure to do so will
cause the tool to start immediately the next time it is plugged in. Damage or injury
could result.

To release the locking mechanism, depress the trigger fully, then release it. Before
using the tool each time, be sure that the locking button release mechanism is
working freely.
Do not lock the switch on when drilling by hand so that you can instantly release the
trigger switch if the bit binds in the hole.
VARIABLE SPEED TRIGGER SWITCH
This switch permits speed control: the farther the trigger is de pressed, the higher the
speed of the drill.
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 for using abrasive and polishing accessories.
REVERSING LEVER
The reversing lever (B) changes the direction of rotation of the drill and is used when
backing out screws and jammed drill bits.
To operate the tool in reverse, release the trigger switch and push the lever to the
left (when viewed from the chuck end) as shown in Figure 2. To operate the drill in
forward for drilling holes or driving screws (as well as when using other accessories)
release the trigger switch and push the lever to the right (when viewed from the chuck
end).
Return the reversing lever to the forward position after all operations in reverse are
completed.

OPERATION

WARNING: Shock Hazard. 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.

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,
