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.

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.
Drilling in Metal
Start drilling with slow speed and increase to full power
while applying firm pressure on the tool. A smooth even
flow of metal chips indicates the proper drilling rate. Use a
cutting lubricant when drilling metals. The exceptions are
cast iron and brass which should be drilled dry.
nOTE: Large [5/16" (8 mm) to 1/2" (13 mm)] holes in steel
can be made easier if a pilot hole [5/32" (4 mm) to 3/16" (5
mm)] is drilled first.
Drilling in Wood
Start drilling with slow speed and increase to full power
while applying firm pressure on the tool. Holes in wood can
be made with the same twist drills used for metal. These
bits may overheat unless pulled out frequently to clear chips
from the flutes. Work that is apt to splinter should be backed
up with a block of wood.
Drilling in Masonry
When drilling in masonry, use carbide-tipped bits rated for
percussion drilling and be certain that the bits are sharp.
Use a constant and firm force on the tool to drill most
effectively. A smooth, even flow of dust indicates the proper
drilling rate.
MAINTENANCE

WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start-up can cause injury.
Your D WALT power tool has been designed to operate
e
over a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon proper
tool care and regular cleaning.
6
Motor Brushes
D WALT uses an advanced brush system which
e
automatically stops the drill when the brushes wear out.
This prevents serious damage to the motor. New brush
assemblies are available at authorized D
centers. Always use identical replacement parts.
Lubrication
Self-lubricating bearings are used in the tool and periodic
relubrication is not required. In the unlikely event that
service is ever needed, take your tool to an authorized
service location.
Cleaning

WARNING: Blow dirt and dust out of all air vents with
clean, dry air at least once a week. To minimize the
risk of eye injury, always wear approved eye protection
when performing this.

WARNING: Never use solvents or other harsh
chemicals for cleaning the non-metallic parts of
the tool. These chemicals may weaken the plastic
materials used in these parts. Use a cloth dampened
only with water and mild soap. Never let any liquid
get inside the tool; never immerse any part of the tool
into a liquid.
