Work Area
Keep your work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power
tools create sparks which may ignite the
dust or fumes.
Keep by-standers, children, and visitors
away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
Grounded tools must be plugged into an
outlet properly installed and grounded in
accordance with all codes and
ordinances. Never remove the grounding
prong or modify the plug in any way. Do
not use any adaptor plugs. Check with a
qualified electrician if you are in doubt as
to whether the outlet is properly
grounded. If the tools should electrically
malfunction or break down, grounding
provides a low resistance path to carry
electricity away from the user. Improper
grounding can shock, burn or electrocute.
Grounded tools are equipped with three
conductor cord and three prong type plugs.
Before plugging in the tool be certain the
outlet voltage supplied is within the voltage
marked on the nameplate. Do not use “AC
only” rated tools with a DC power supply.
Avoid body contact with grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased
risk of electric shock if your body is
grounded. If operating the power tool in
damp locations is unavoidable, a Ground
Fault Circuit Interrupter must be used to
supply the power to your tool. Electrician’s
rubber gloves and footwear will further
enhance your personal safety.
Don't expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
Do not abuse the cord. Never use the
cord to carry the tools or pull the plug
from an outlet. Keep cord away from
heat, oil, sharp edges or moving parts.
Replace damaged cords immediately.
Damaged cords increase the risk of electric
shock.
When operating a power tool outside, use
an outdoor extension cord marked "W-A"
or "W." These cords are rated for outdoor
use and reduce the risk of electric shock.
Refer to “Recommended sizes of Extension
Cords” in the Accessory section of this
manual.
Personal Safety
Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use tool while tired or
under the influence of drugs, alcohol, or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
Dress properly. Do not wear loose
clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves away
from moving parts. Loose clothes, jewelry,
or long hair can be caught in moving parts.
Keep handles dry, clean and free from oil
and grease.
Avoid accidental starting. Be sure switch
is “OFF” before plugging in. Carrying tools
with your finger on the switch or plugging in
tools that have the switch “ON” invites
accidents.
Remove adjusting keys or wrenches
before turning the tool “ON”. A wrench or
a key that is left attached to a rotating part of
the tool may result in personal injury.
Do not overreach. Keep proper footing
and balance at all times. Proper footing
and balance enables better control of the
tool in unexpected situations.
Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must
be used for appropriate conditions.
Read and understand all instructions. Failure to follow all instructions
listed below, may result in electric shock, fire and/or serious personal injury.

Safety Rules for Drivers
Hold tool by insulated gripping surfaces
when performing an operation where the
cutting tools may contact hidden wiring
or its own cord. Contact with a “live” wire
will make exposed metal parts of the tool
“live” and shock the operator. Do not drill,
fasten or break into existing walls or other
blind areas where electrical wiring may exist.
If this situation is unavoidable, disconnect all
fuses or circuit breakers feeding this
worksite.
Always wear safety goggles or eye
protection when using this tool.
Secure the material being fastened. Never
hold it in your hand or across legs.
Unstable support can cause the drill bit to
bind causing loss of control and injury.
Never leave the trigger locked "ON".
Before plugging the tool in, check that the
trigger lock is "OFF". Accidental start-ups
could cause injury.
Position the cord clear of rotating driver.
Do not wrap the cord around your arm or
wrist. If you lose control and have the cord
wrapped around your arm or wrist it may
entrap you and cause injury.
Be aware of the location and setting of
the switch "Lock-ON" button. If the switch
is locked "ON" during the use, be ready for
emergency situations to switch it "OFF", by
first pulling the trigger then immediately
releasing it without pressing the "Lock-ON"
button.
Be prepared for a strong reaction torque
when "seating" or removing a screw. The
driver motor housing will tend to twist in the
opposite direction when "seating" or
removing a screw.
Tool Use and Care
Use clamps or other practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand
or against your body is unstable and may
lead to loss of control.
Do not force tool. Use the correct tool for
your application. The correct tool will do
the job better and safer at the rate for which
it is designed.Do not use tool if switch
does not turn it “ON” or “OFF”. Any tool
that cannot be controlled with the switch is
dangerous and must be repaired.
Disconnect the plug from the power
source before making any adjustments,
changing accessories, or storing the tool.
Such preventive safety measures reduce the
risk of starting the tool accidentally.
Store idle tools out of reach of children
and other untrained persons. Tools are
dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting
tools sharp and clean. Properly
maintained tools, with sharp cutting edges
are less likely to bind and are easier to
control. Any alteration or modification is a
misuse and may result in a dangerous
condition.
Check for misalignment or binding of
moving parts, breakage of parts, and any
other condition that may affect the tools
operation. If damaged, have the tool
serviced before using. Many accidents are
caused by poorly maintained tools. Develop
a periodic maintenance schedule for your
tool.
Use only accessories that are
recommended by the manufacturer for
your model. Accessories that may be
suitable for one tool, may become
hazardous when used on another tool.
Service
Tool service must be performed only by
qualified repair personnel. Service or
maintenance performed by unqualified
personnel could result in a risk of injury. For
example: internal wires may be misplaced or
pinched, safety guard return springs may be
improperly mounted.
When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance Instructions may create a risk
of electric shock or injury. Certain cleaning
agents such as gasoline, carbon
tetrachloride, ammonia, etc. may damage
plastic parts.
BM 3609929656 10/03 10/17/03 12:13 PM Page 3
Do not use dull or damaged bits and
accessories.
Check to see that keys and adjusting
wrenches are removed from the driver
before switching the tool "ON". Keys or
wrenches can fly away at high velocity
striking you or a bystander.
Do not run the tool while carrying it at
your side. A spinning drill bit could become
entangled with clothing and injury may
result.
Some dust created by
power sanding, sawing,
grinding, drilling, and other construction
activities contains chemicals known to
cause cancer, birth defects or other
reproductive harm. Some examples of
these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement
and other masonry products, and
• Arsenic and chromium from chemically-
treated lumber.
Your risk from these exposures varies,
depending on how often you do this type of
work. To reduce your exposure to these
chemicals: work in a well ventilated area,
and work with approved safety equipment,
such as those dust masks that are specially
designed to filter out microscopic particles.

Operating Instructions
VARIABLE SPEED CONTROLLED
TRIGGER SWITCH
Your tool is equipped with a variable speed
trigger switch. The tool can be turned "ON" or
"OFF" by squeezing or releasing the trigger. The
speed can be adjusted from the minimum to
maximum nameplate RPM by the pressure you
apply to the trigger. Apply more pressure to
increase the speed and release pressure to
decrease speed.
"LOCK-ON" BUTTON
The "Lock-ON" button, located near the
trigger allows for continuous operation at
maximum RPM without holding the trigger.
TO LOCK TRIGGER "ON": squeeze trigger,
depress button and release trigger.
TO UNLOCK THE TRIGGER: squeeze trigger
and release it without depressing the "LockON" button.
If the “Lock-ON” button is
continuously being de-
pressed, the trigger can not be released.
REVERSING SWITCH LEVER
The reversing switch lever is located above the
trigger switch and is used to reverse rotation of
the bit.
To use driver in "Forward" rotation, move lever
to left side of tool. To "Reverse" the rotation of
the bit move the lever to the right side of the
tool. The center position of the lever is the
"Lock-OFF" position.
Do not change direction of
rotation until the tool comes
to a complete stop. Shifting during rotation of
the chuck can cause damage to the tool.
BELT CLIP
Your tool is equipped with a belt clip that
allows you to conveniently attach your driver to
your belt. This feature will allow you to have
both hands free when climbing a ladder or
moving to another work area.
!
WARNING
1. Support the tool so that steady, even
pressure is applied to the screwdriving bit.
Operate the trigger switch by depressing with
one or two fingers.
2. Lock the tool on for continuous operation.
The bit will not rotate until the clutch is
engaged.
3. Place a drywall screw on the bit. The
magnetic bit holder will hold any steel drywall
screw without any additional assistance.
4. Press the screw point against the drywall
with steady even pressure. At this point, the
clutch will engage, driving the screw to the
pre-set depth. Once the screw bottoms out, a
ratcheting sound will be heard for a second.
5. When properly set, the screw head should
pull into the drywall paper without cracking or
tearing the paper, then release slightly below
flush with the drywall board. In this manner,
minimum work is left when spackling screw
heads and taping the seams.
6. If it becomes necessary to remove the
screw, remove the snap off nose piece,
reverse the direction of rotation (when the
motor is in the "OFF" position.) Place the bit
tip into the screw, switch tool "ON" and apply
pressure to engage the clutch. Replace nose
piece by pushing and slightly twisting to seat
into the depth gauge. Set lever back to
forward while the trigger switch is in the “OFF”
position.
!
CAUTION
Tool Tips
DEPTH CONTROL
The depth control should be adjusted so that
the drywall screw is set slightly below the
drywall surface.
DEPTH ADJUSTMENT
Your driver will continue to drive as long as
enough pressure is applied to the bit to keep
the clutch engaged. Models 1420VSR,
1420VSRL, 1421VSR, and 1422VSRQ are
equipped with a quiet clutch that eliminates
ratcheting noise and prolongs clutch life.
The nose piece, upon contacting the work,
prevents further pressure on the bit. Driving
then stops regardless of pressure continued by
the operator.
1. Pull firmly on the locking ring, moving it
forward and away from the spline section of
BM 3609929656 10/03 10/17/03 12:13 PM Page 7
-8-
the clutch housing. Then turn it until the nose
piece reaches the predetermined position.
2. Each 1/2 turn of the locking ring equals 1/32
inch change in depth. Once the desired depth
setting is obtained, push the locking ring back
toward the gear housing and turn slightly to
match the splines, then push in firmly to lock it
into place.
3. Before beginning, always test-drive a
sample screw into a piece of scrap installation
material to check desired depth setting.
REPLACING BIT TIPS AND
BIT TIP HOLDERS
1. Remove the plastic nose piece by grasping
firmly WITH FINGERS and pulling straight out.
DO NOT USE PLIERS.
2. Remove the bit tip by grasping firmly and
pulling straight out. If the bit tip holder comes
out with the bit, separate them. If you are
replacing the bit tip holder too, grasp it firmly
and pull it straight out. If you cannot remove
the bit tip or the bit tip holder using fingers
only, you may use pliers on these two parts
only. DO NOT USE PLIERS ON NOSE PIECE.
Reverse the process to the point of installing
nose piece. Then WITH YOUR FINGERS,
install nose piece by pushing inward. Twist if
necessary to seat properly and lock in place.
