Chuck Removal (Fig. C, D)
1. Place chuck key in chuck as shown in Figure C. Using
a wooden mallet or similar object, strike key sharply in
a CLOCKWISE direction. This will loosen screw inside
chuck.
2. Open chuck jaws fully. Insert screwdriver into front of
chuck between jaws to engage screw head. Remove
screw by turning clockwise (left-hand thread).
3. Place key in chuck as shown in Figure D. Using a
wooden mallet or similar object, strike key sharply in a
COUNTERCLOCKWISE direction. This will loosen chuck
so that it can be unscrewed by hand.

OPERATION

WARNING: Always observe the safety instructions
and applicable regulations.

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.
Drilling
1. Use sharp drill bits only. For WOOD, use twist drill bits,
spade bits, power auger bits, or hole saws. For METAL,
use high-speed steel twist drill bits or hole saws. For
MASONRY, such as brick, cement, cinder block etc., use
carbide-tipped bits.
2. 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.
3. 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.
4. Hold drill firmly to control the twisting action of the drill.
Use side handle.

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.
5. 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

6. To minimize stalling on breaking through the material,
reduce pressure on drill and ease the bit through the
last fractional part of the hole.

7. Keep the motor running when pulling the bit back out
of a drilled hole. This will help prevent jamming.
Drilling in Wood
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. For larger holes, use
spade bits, power auger bits, or hole saws. Work that is likely
to splinter should be backed up with a block of wood.
Drilling in Metals
Use a cutting lubricant when drilling metals. The exceptions
are cast iron and brass which should be drilled dry. The
cutting lubricants that work best are sulphurised cutting oil
FIG. D
or lard oil; bacon grease will also serve the purpose.
Drilling in Masonry
Use carbide tipped masonry bits at low speeds. Keep even
force on the drill but not so much that you crack the brittle
materials. A smooth, even flow of dust indicates the proper
drilling rate.
Maintenance

WARNING: To reduce the risk of injury, turn unit
off and disconnect tool from power source before
installing and removing accessories, 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.

Lubrication
All bearings used are factory lubricated to last the life of the
tool. All needle bearings used receive their lubrication from
the grease in the gear case. Clean and relubricate gear case
yearly or whenever servicing requires the gear case to be
removed. Use type and quantity of grease shown on Parts
Bulletin packed with your tool.
Gear case is removed by removing the four screws from the
front of the tool. If the chuck is too large to permit removal
of the two top screws, see instructions for chuck removal.
Motor Brushes
This D WALT tool uses an advanced brush system which
e
auto matically stops the tool when the brushes wear out.
This prevents seri ous damage to the motor.
