TO REDUCE RISK OF INJURY :
• Before any use, be sure everyone using this tool reads and understands all safety instructions and other
information contained in this manual.
• Save these instructions and review frequently prior to use and in instructing others.
WARNING: When using electric tools, basic safety precautions should always be followed to
reduce risk of fire, electric shock, and personal injury, including the following.
READ ALL INSTRUCTIONS
General Safety Warnings and Instructions for All Tools
• KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.
• CONSIDER WORK AREA ENVIRONMENT. Don’t expose power tools to rain. Don’ t use power tools in
damp or wet locations. Keep work area well lit. Do not use in presence of flammable liquids or gases.
Motors in these tools normally spark, and the sparks may ignite the fumes.
• GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded surfaces. For example; pipes,
radiators, ranges, refrigerator enclosures. Use extreme caution when drilling, driving, or cutting into walls,
floors, ceilings or other areas or wherever live electrical wires may be contacted, do not touch any metal
parts of the tool. Hold the tools only by the plastic handle to prevent electric shock.
• KEEP CHILDREN AWAY .Do not let children and visitors contact tool or extension cord. All children and
visitors should be kept away from work area.
• STORE IDLE TOOLS. When not in use, tools should be stored in dry, and high or locked-up place–out of
reach of children.
• DON’T FORCE TOOL. It will do the job better and safer at the rate for which it was intended.
• USE RIGHT TOOL. Don’t force small tool or attachment to do the job of a heavy-duty tool. Don’t use tool
for purposes not intended.
• DRESS PROPERLY . Do not wear loose clothing or jewelry . They can be caught in moving parts. Rubber
gloves and non-skid footwear are recommended when working outdoors. Wear protective hair covering
to contain long hair.
• USE SAFETY GLASSES AND OTHER SAFETY EQUIPMENT. Use safety goggles or safety glasses with side
shields, complying with applicable safety standards and, when needed, a face shield. Also use face or
dust mask if cutting operation is dusty. This applies to all persons in the work area. Also use a hard hat,
hearing protection, gloves, safety shoes and dust collection systems when specified or required.
• DON’T ABUSE CORD. Never carry tool by cord or yank it to disconnect from receptacle. Keep cord from
heat, oil, and sharp edges.
• SECURE WORK. Use clamps or a vise to hold work. It’s safer than using your hand and it frees both hands
to operate tool.
• DON’T OVERREACH. Keep proper footing and balance at all times.
• MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and safer performance. Follow
instructions for lubricating and changing accessories. Inspect tool cords periodically and if damaged, have
repaired by authorized service facility. Inspect extension cords periodically and replace if damaged. Keep
handles dry, clean, and free from oil and grease.
• DISCONNECT TOOLS. Unplug the tool when not in use, when moving tool from place to place, before
servicing, and when changing accessories (such as blades, bits, cutters) or making adjustments.
• REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and adjusting
wrenches are removed from tool before turning it on.
• AVOID UNINTENTIONAL STARTING. Don’t carry tool with finger on switch. Be sure switch is off when
plugging in.
• EXTENSION CORDS. Make sure your extension cord is in good condition. When using an extension cord,
be sure to use one heavy enough to carry the current your product will draw.An undersized cord will
cause a drop in line voltage resulting in loss of power and overheating. The following table shows the
correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next
heavier gage. The smaller the gage number, the heavier the cord.
• STAY ALERT. Watch what you are doing. Use common sense. Do not operate tool when you are tired or
otherwise impaired.
• CHECK DAMAGED PARTS.Before further use of the tool, a guard or other part that is damaged should be
carefully checked to determine that it will operate properly and perform its intended function. Check for
alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other
conditions that may affect its operation. A guard or other part that is damaged should be properly
repaired or replaced by an authorized service center. Do not use tool if switch does not turn it on and off.
• REPAIRS AND SERVICE.Repairs, maintenance and any adjustments not specified in this manual should be
performed by Black & Decker authorized service centers or other qualified service organizations, always
using identical replacement parts.
• USE OF ACCESSORIES AND ATTACHMENTS. The use of any accessory or attachment not recommended
for use with the tool could be hazardous. Note: Refer to the accessory section of this manual for further
details.
Safety Warnings and Instructions: Double Insulation
Double insulated tools are constructed throughout with two separate layers of electrical insulation or a
double thickness of insulation between you and the tool’s electrical system. Tools built with double insulation
are not intended to be grounded. As a result, your tool is equipped with a two prong plug which permits
you to use extension cords without concern for maintaining a ground connection.
Double insulation does not take the place of normal safety precautions when operating this tool. The
insulation system is for added protection against injury resulting from a possible electrical insulation failure
within the tool.
REPLACEMENT PARTS: When servicing use only identical replacement parts. Repair or replace damaged
cords.
Safety Warnings and Instructions: Polarized Plugs
Polarized plugs (one blade is wider than the other) are used on equipment to reduce the risk of electric
shock. When provided, this plug will fit into a polarized outlet only one way. If the plug does not fit fully
into the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper
outlet. Do not change the plug in any way.
Motor
Your tool is powered by a Black & Decker built motor. Be sure your power supply agrees with the
nameplate marking. A marking of 120 volts, 50/60 Hz or 120 volts AC only means than the tool is
designed to operate on normal 120 volt house current. Voltage decrease of more than 10% will cause loss
of power and overheating. All Black & Decker tools are factory tested. If this tool does not run,
check the power supply.

Operating Instructions
Side Handle (Figure 1)
ALW AYS USE THE SIDE HANDLE.
The side handle is assembled and ready to be placed on the drill. Slide the handle over the keyless chuck
and move it onto the collar just behind the chuck. Be sure the handle is on the front of the tool, not touching
the chuck. A back and forth motion will make the process easier. The side handle can be rotated anywhere
around the tool for right hand or left hand use.
NOTE: It may be necessary to remove the depth rod when rotating the side handle.
To adjust the depth rod, loosen (counterclockwise) the side handle and slide the depth rod to the desired
position. Tightening the side handle (clockwise) will secure the depth rod in place.
The depth rod will allow you to drill or drive screws to a desired depth. Once the depth rod makes contact
with the surface of the material, the bit will stop drilling. (Bit will continue to rotate.)
Switches
To start drill, depress trigger switch; to stop drill, release trigger. To lock trigger in ON position for
continuous operation, depress trigger and push lock-on button shown in Figure 2, then gently release
trigger. To release locking mechanism, depress trigger fully, then release it. Before using the tool (each time)
be sure that the lock-on 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 lock-on
button is for use only when the drill is mounted in a drill press stand or otherwise held stationary. Be sure to
release the lock-on 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.
Variable Speed Switch
This permits FREE HAND speed control—the further the trigger is depressed, the higher the R.P.M. Use
lower speeds for starting holes without a center punch, drilling in metal, plastics, and ceramics, or driving
screws. Higher speeds are better for drilling wood and composition boards, and for using abrasive and
polishing accessories.
Reversing Switch
To operate your drill in reverse, a reversing switch has been provided, as shown in Figure 3A. To operate
the drill in forward (most drilling operations and driving screws) slide the reversing switch to the left, as
viewed from the chuck end (Figure 3A). To operate in reverse (removing screws or jammed drill bits) slide
the reversing switch to the right (Figure 3B). Do not move the switch while the drill is running. This can
damage the drill.
Hammer Action
Your drill has hammer action which is engaged by sliding the hammer/drill selector lever. To select
hammering, turn off the drill and slide the lever toward the hammer symbol on the drill housing, as shown
in Figure 4A. To select drilling, turn off the drill and slide the lever toward the drill symbol on the drill
housing, as shown in Figure 4B.
Operation
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 steel twist drill bits or hole saws. For MASONRY, such as brick, cement,
cinder block, etc., use carbide-tipped bits and hammer action.
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.
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. 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
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.
NOTE: Large 5/16" (7.9mm) to 3/8" (9.5mm) holes in steel can be made easier if a pilot hole 5/32"
(4mm) to 3/16" (4.8mm) is drilled first.
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.
DRILLING IN MASONRY
Select "Hammer Action." Use carbide-tipped masonry bits. 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 Removal
UNPLUG DRILL.
NOTE: Before attempting to remove chuck, shift the drill into the drilling mode (not hammer).
Tighten the chuck around the shorter end of a hex key (not supplied) of 1/4" (6.4mm) or greater size.
Using a soft hammer, strike the longer end in the clockwise direction, as shown in Figure 5. This will loosen
the screw inside the chuck.
Open chuck jaws fully, insert screwdriver (or T orx tool if required) into front of chuck between jaws to
engage screw head. Remove screw by turning clockwise (left-hand-thread). Place hex key in chuck as
shown in Figure 6. Using a soft hammer, strike key sharply in the counterclockwise direction. This will
loosen the chuck so that it can be unscrewed by hand.
Chuck Installation
Screw chuck on by hand as far as it will go. Tighten the chuck around the shorter end of a 1/4" (6.4mm)
or larger hex key (not supplied). Strike the longer end in the clockwise direction with a soft hammer, as
shown in Figure 6. Firmly tighten screw inside chuck.
