Shifting to the Desired Speed
To select high speed (1200 RPM) pull up on the speed selector and slide it to the position shown
in Figure 5. Make sure that when you release the selector, it snaps down into the detent in the
housing.
To select low speed (300 RPM) pull up on the speed selector and slide it to the position shown
in Figure 6. Make sure that when you release the selector, it snaps down into the detent in the
housing.
NOTE: It may be necessary to rotate the chuck slightly by hand when shifting speeds. Never
change speeds when the drill is running or coasting.
Switches
Depressing the trigger switch turns the tool "ON," releasing the trigger switch turns the tool
"OFF." There is a slide switch built into the handle directly behind the trigger switch for operating
in reverse. For drilling, this switch is put in the "F" position and for reversing operations, it is
pushed to the "R" position.
NOTE: The switch provided is a common part for use on several other tools. Ignore the "HI/LO"
markings for this drill. A built in mechanical interlock prevents operation of the slide switch
unless the trigger is released. Avoid reversing the drill's direction while it is still coasting to a
stop.
Operation
CAUTION: Always unplug the tool when attaching or changing bits or accessories.
1. Open the chuck jaws by turning collar with fingers and insert bit fully into the chuck. Tighten
chuck collar by hand. Place chuck key in each of the three holes, and tighten in clockwise
direction. It's important to tighten chuck with all three holes. To release bit, turn chuck key
counter clockwise in just one hole, then loosen chuck by hand.
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 steel 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.
4. 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.
5. 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.
6. 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 OFF AND ON IN AN ATTEMPT TO START A STALLED
DRILL — THIS CAN DAMAGE THE DRILL.
7. To minimize stalling on breaking through the material, reduce pressure on drill and ease the
bit through the last fractional part of the hole.
8. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent
jamming.
9. A ratcheting sound heard while using the tool in low speed indicates that the clutch is
disengaging due to a high load. Continuous use of the tool with the clutch ratcheting is not
recommended.
Drilling in Metal
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 sulphurized cutting oil or lard oil;
bacon grease will also serve the purpose.
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 Power Drill
Wood Bits. Work that is apt to splinter should be backed up with a block of wood. When using
Self Feed bits, no pressure is required as these bits will pull themselves into the wood.
NOTE: If the clutch slips while using a self feed bit, rock the drill slightly by pushing the switch
handle toward the material being drilled and then pulling it back toward you several times.
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.
Chuck Key Holder
1. Push double-hole end of holder through the slot in other end of holder (Fig. 7).
2. Slip loop over electric plug and draw loop tight around cord (Fig. 8).
3. Push ends of chuck key handle through two holes in end of holder (Fig. 9).
Cleaning
With the tool motor running, blow dirt and dust out of all air vents with dry air at least once a
week.
Lubrication
Your tool was properly lubricated before leaving the factory. In from two to six months,
depending upon use, take or send your tool to a D
service organization for a complete cleaning, inspection and relubrication.
Tools used constantly on production or heavy duty jobs or exposed to heat may require more
frequent lubrication. Tools "out of service" for long periods should be relubricated before being
put back into service.
Motor Brushes
This D WALT tool uses an advanced brush system which automatically stops the drill when the
E
brushes wear out. This prevents serious damage to the motor.
Accessories
Recommended accessories for use with your tool are available at extra cost from your
distributor or local service center.
CAUTION: The use of any non-recommended accessory may be hazardous.
