Motor Brushes

D WALT uses an advanced brush system which automatically stops
E
the drill when the brushes wear out. This prevents serious damage to
the motor.
Switch
To start drill, depress trigger switch; to stop drill, release trigger.
To lock trigger in "ON" position for continuous operation, depress
trigger and push up locking button "A" Figure 1, then gently
release trigger. To release locking mechanism, depress 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.
The locking button is for use only when the drill is mounted in a
drill press stand or otherwise held stationary.
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.

THE VARIABLE SPEED TRIGGER SWITCH permits speed
control – the farther the trigger is depressed, 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.
THE REVERSING LEVER The reversing lever 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 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

DRILLING
NOTE: Always use side handle and two-handed grip when
operating this drill.
1. Always unplug the drill when attaching or changing bits or
accessories.
2. Use sharp drill bits only. For WOOD, use twist drill bits, spade
bits, power auger bits, or hole saws. For METAL, use high
speed twist drill bits or hole saws. For MASONRY, such as
brick, cement, cinder block, etc., use carbide-tipped bits.
3. Be sure the material to be drilled is anchored or clamped firmly.
If drilling thin material, use a wood "back-up" block to prevent
damage to the material.
