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
A battery operated tool with integral
batteries or a separate battery pack must
be recharged only with the specified
charger for the battery.
A charger that may
be suitable for one type of battery may create
a risk of fire when used with another battery.
Use battery operated tool only with
specifically designated battery pack.
Use
of any other batteries may create a risk of fire.
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.
Avoid accidental starting. Be sure switch
is in the locked or off position before
inserting battery pack.
Carrying tools with
your finger on the switch or inserting the
battery pack into a tool with 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 enable 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.
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.
A tool that cannot be controlled
with the switch is dangerous and must be
repaired.
Disconnect battery pack from tool or place
the switch in the locked or off position
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.
When battery pack is not in use, keep it
away from other metal objects like: paper
clips, coins, keys, nails, screws, or other
small metal objects that can make a
connection from one terminal to another.
Shorting the battery terminals together may
cause sparks, burns, or a fire.

Safety Rules for Cordless Drills/Drivers
Maintain tools with care. Keep cutting
tools sharp and clean.
Properly maintained
tools with sharp cutting edge are less likely to
bind and are easier to control.
Check for misalignment or binding of
moving parts, breakage of parts, and any
other condition that may affect the tool's
operation. If damaged, have the tool
serviced before using.
Many accidents are
caused by poorly maintained tools.
Use only accessories that are
recommended by the manufacturer for
your model.
Accessories that may be
suitable for one tool may create a risk of
injury when used on another tool.
Service
Tool service must be performed only by
q
ualified repair personnel.
S
ervice or
maintenance performed by unqualified
personnel may result in a risk of injury.
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
shock or injury.
Hold tool by insulated gripping surfaces
when performing an operation where the
cutting tools may contact hidden wiring.
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 hold the tool with both hands. If
the bit jams two hands will give you
maximum control over torque reaction or
kickback.
Always wear safety goggles or eye
protection when using this tool. Use a
dust mask or respirator for applications
which generate dust.
Secure the material being drilled. Never
hold it in your hand or across legs.
Unstable support can cause the drill bit to
bind causing loss of control and injury.
Disconnect battery pack from tool or
place the switch in the locked or off
position before making any assembly,
adjustments or changing accessories
.
Such preventive safety measures reduce the
risk of starting the tool accidentally.
Position yourself to avoid being caught
between the tool or side handle and walls
or posts.
Should the bit become bound or
jammed in the work, the reaction torque of
the tool could crush your hand or leg.
If the bit becomes bound in the
workpiece, release the trigger
immediately, reverse the direction of
rotation and slowly squeeze the trigger to
back out the bit.
Be ready for a strong
reaction torque. The drill body will tend to
twist in the opposite direction as the drill bit is
rotating.
Do not grasp the tool or place your hands
too close to the spinning chuck or drill
bit.
Your hand may be lacerated.
When installing a drill bit, insert the shank
of the bit well within the jaws of the
chuck.
If the bit is not inserted deep
enough, the grip of the jaws over the bit is
reduced and the loss of control is increased.
Do not use dull or damaged bits and
accessories.
Dull or damaged bits have a
greater tendency to bind in the workpiece.
When removing the bit from the tool avoid
contact with skin and use proper
protective gloves when grasping the bit or
accessory.
Accessories may be hot after
prolonged use.
Check to see that keys and adjusting
wrenches are removed from the drill

Battery/Charger
before switching the tool "ON". Keys or
wrenches can fly away at high velocity
striking you or a bystander.
Do not run the drill while carrying it at
your side.
A spinning drill bit could become
entangled with clothing and injury may result.
This tool may be used with sanding and
polishing disks, grinding wheels, wire
wheel and wire cup brushes. These
accessories must be rated for at least the
speed recommended on the tool warning
label.
Wheels and other accessories running
over rated speed can fly apart and cause
injury.
Avoid bouncing and snagging the wheels,
discs or brushes especially when working
corners, sharp edges, etc.
This can cause
loss of control and kickback.
Use a stud sensor to determine where
studs may be located. The stud sensor
may also be able to detect other objects
hidden in a wall such as conduit, gas or
water pipes. If you are uncertain about
the work area call the local utility
company for assistance before beginning
the project.
Striking or cutting into a gas
line will result in explosion. Water entering
an electrical device may cause electrocution.
Cutting into live electrical wiring may cause a
shock hazard.
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
Y
our tool is equipped with a variable speed
trigger switch. The tool speed can be
controlled from the minimum to the maximum
nameplate RPM by the pressure you apply to
the trigger. Apply more pressure to increase
the speed and release pressure to decrease
speed. This accurate speed control enables
you to drill without center punching. It also
permits you to use as a power screwdriver.
Bits are available for driving screws as well as
running bolts and nuts.
FORWARD/REVERSING LEVER &
TRIGGER LOCK
Your tool is equipped with a forward/
reversing lever and trigger lock located above
the trigger (Fig. 1). This lever was designed
for changing rotation of the chuck, and for
locking the trigger in an “OFF” position to help
prevent accidental starts and accidental
battery discharge. For forward rotation, (with
chuck pointed away from you) move the lever
to the far left. For reverse rotation move the
lever to the far right. To activate trigger lock
move lever to the center 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.
ADJUSTABLE CLUTCH
Your tool features 6 clutch settings. Output
torque will increase as the clutch ring, is
rotated from 1 to 5. The drill “ ” position
will lock up the clutch to permit drilling and
driving heavyduty work, and also enables bits
to be changed quickly and easily in the
keyless chuck.
BRAKE
When the trigger switch is released it
activates the brake to stop the chuck quickly.
This is especially useful in the repetitive
driving and removal of screws.
INSERTING BIT
For small bits, open jaws enough to insert
the bit up to the flutes. For large bits, insert
the bit as far as it will go. Center the bit as
you close the jaws by hand. This positions
the bit properly, giving maximum contact
b
etween the chuck jaws and the bit shank.
To tighten, hold the chuck collar firmly with
one hand and securely tighten the chuck
sleeve with the other hand (Fig. 2).
Do not use the power of
the drill while grasping
chuck to loosen or tighten bit.
Friction burn
or hand injury is possible if attempting to
grasp the spinning chuck.
REMOVING CHUCK
Rotate the clutch ring to the drill bit
symbol “ ”. Open the chuck all the way,
remove left-hand thread screw inside chuck
by turning it clockwise. Insert the short arm of
a 3/8" hex key wrench and close jaws on flats
of wrench. Strike long arm of wrench sharply
counterclockwise, remove wrench and
unthread chuck from spindle (Fig. 2).
INSTALLING CHUCK
Always keep the spindle threads, the threads
of the chuck and securing screw free of
debris. To install a chuck, reverse “removing
the chuck” procedure.
RELEASING AND INSERTING
BATTERY PACK

* STUD FINDER
Your tool may be equipped with a stud finder
located on top of your tool.
To remove, simply slide off the housing
towards the back of the tool.
Before first use, open the battery compartment
door and remove the protective plastic insert
from between the batteries. Assure proper
battery placement as shown in the
compartment and replace the door (Fig. 4).
Your stud finder uses four L1154 button cell
batteries.
To use, place stud finder flat against the wall
with LEDS pointing up. Be sure to keep your
fingers below the line on the stud finder to
avoid false readings (Fig. 5).
Push and hold button to calibrate and activate
unit (Green LED) (Fig. 5). Slowly slide unit
horizontally across the wall without picking up
or tilting.
The yellow LED indicates you are
approaching a stud.
The red LED indicates stud edge. Mark this
spot.
With the button still depressed, continue
sliding the stud finder in the same direction
until the red LED turns off. This is the studs
other edge. Mark this spot.
The midpoint of the two marks is the center of
the stud.
A fault has occurred when all three LEDS
flash . To correct, simply restart the circuit.
Stud finders can detect
other objects besides
studs, such as electrical wiring and
metal/plastic pipes.
Contact with a “live”
wire will make exposed metal parts of the tool
“live” and shock the operator.
(Studs are normally spaced 16 or 24 inches
apart and are 1-1/2" wide. Beware of anything
closer together or of a different width.) Always
turn off power when working near electrical
wires.
DRILL BIT STORAGE COMPARTMENT
AND QUICK REFERENCE GAUGE
Your tool may be equipped with a bit storage
compartment and quick reference gauge
located on top of your tool.
To remove, simply slide off the housing
towards the back of the tool.

1. The battery pack accepts only about 80%
of its maximum capacity with its first few
charge cycles. However, after the first few
charge cycles, the battery will charge to full
capacity.
2. The charger was designed to fast charge
the battery only when the battery temperature
is between 40˚F (4˚C) and 105˚F (41˚C).
3. A substantial drop in operating time per
charge may mean that the battery pack is
nearing the end of its life and should be
replaced.
4. If you anticipate long periods (i.e. a month
or more) of non-use of your tool, it is best to
run your tool down until it is fully discharged
before storing your battery pack. After a long
period of storage, the capacity at first recharge
will be lower. Normal capacity will be restored
in two or three charge/discharge cycles.
Remember to unplug charger during storage
period.
5. If battery does not charge properly:
a. Check for voltage at outlet by plugging
in some other electrical device.
b. Check to see if outlet is connected to a
light switch which turns power “off” when lights
are turned off.
c. Check battery pack terminals for dirt.
Clean with cotton swab and alcohol if
necessary.
d.
If you still do not get proper charging,
take or send tool, battery pack and charger to
your local Skil Service Center. See “Tools,
Electric” in the Yellow Pages for names and
addresses.
Note: Use of charger’s or battery packs not
sold by Skil will void the warranty.
IMPORTANT CHARGING NOTES
-10-
Plug charger cord into your standard power
outlet. Before inserting battery pack, remove
protective cap, then insert battery pack into
charger (Fig. 6).
The charger’s green light (Fig. 7), will turn
“ON”. The green light remains ‘‘ON’’ as long
as charger is plugged in, and does not shut off.
After normal usage, the battery pack requires
approximately 3 hours or less charging time to
become fully charged. If the battery pack is
run-down completely, it may require up to 5
hours charging time to become fully charged.
When the battery pack is fully charged, unplug
the charger (unless you're charging another
battery pack) and slip the battery pack back
into the tool handle.
To prevent fire or injury when batteries are not
in tool or charger, always place protective cap
onto end of battery pack.

Operating Tips
You will extend the life of your bits and do
neater work if you always put the bit in contact
with the work before pulling the trigger. During
the operation, hold the tool firmly and exert
light, steady pressure. Too much pressure at
low speed will stall the tool. Too little pressure
will keep the bit from cutting and cause
excess friction by sliding over the surface.
This can be damaging to both tool and bit.
DRILLING WITH VARIABLE SPEED
The trigger controlled variable speed feature
will eliminate the need for center punches in
hard materials. The variable speed trigger
allows you to slowly increase RPM. By using
a slow starting speed, you are able to keep
the bit from “wandering”. You can increase the
speed as the bit “bites” into the work by
squeezing the trigger.
D
RIVING WITH VARIABLE SPEED
Variable speed drills will double as a power
screwdriver by using a screwdriver bit in the
drill mode. The technique is to start slowly,
increasing the speed as the screw runs down.
Set the screw snugly by slowing to a stop.
Prior to driving screws, pilot and clearance
holes should be drilled.
FASTENING WITH SCREWS
This procedure shown in (Fig. 8) will enable
you to fasten materials together with your
Cordless Drill/Screwdriver without stripping,
splitting or separating the material.
First, clamp the pieces together and drill the
first hole 2/3 the diameter of the screw. If the
material is soft, drill only 2/3 the proper length.
If it is hard, drill the entire length.
Second, unclamp the pieces and drill the
second hole the same diameter as the screw
shank in the first or top piece of wood.
Third, if flat head screw is used, countersink
the hole to make the screw flush with the
surface. Then, simply apply even pressure
when driving the screw. The screw shank
clearance hole in the first piece allows the
screw head to pull the pieces tightly together.
The adjustable screw drill accessory will do all
of these operations quickly and easily. Screw
drills are available for screw sizes No. 6, 8, 10
and 12.
DRILL BITS
Always inspect drill bits for excessive wear.
Use only bits that are sharp and in good
condition.
TWIST BITS: Available with straight and
reduced shanks for wood and light duty metal
drilling. High speed bits cut faster and last
longer on hard materials.
CARBIDE TIPPED BITS: Used for drilling
stone, concrete, plaster, cement and other
unusually hard nonmetals. Use continuous
heavy feed pressure when employing carbide
tip bits.
DRILLING WOOD
Be certain workpiece is clamped or anchored
firmly. Always apply pressure in a straight line
with the drill bit. Maintain enough pressure to
keep the drill “biting”.
When drilling holes in wood, twist bits can be
used. Twist bits may overheat unless pulled
out frequently to clear chips from flutes.
Use a “back-up” block of wood for work that is
likely to splinter, such as thin materials.
You will drill a cleaner hole if you ease up on
the pressure just before the bit breaks through
the wood. Then complete the hole from the
back side.
2. Drill same
diameter as
screw shank.
3. Countersink
same diameter
as screw head.
1. Drill 2/3 diameter and
2/3 of screw length for
soft materials, full
length for hard
materials.

WIRE BRUSHES
Work with brushes requires high speeds.
BRUSHING PRESSURE
1. Remember, the tips of a wire brush do the
work. Operate the brush with the lightest
pressure so only the tips of the wire come in
contact with the work.
2. If heavier pressures are used, the wires
will be overstressed, resulting in a wiping
action; and if this is continued, the life of the
brush will be shortened due to wire fatigue.
3. Apply the brush to the work in such a way
that as much of the brush face as possible is
in full contact with the work. Applying the side
or edge of the brush to the work will result in
wire breakage and shortened brush life.
RUNNING NUTS AND BOLTS
Variable speed control must be used with
caution for driving nuts and bolts with socket
set attachments. The technique is to start
slowly, increasing speed as the nut or bolt runs
down. Set the nut or bolt snugly by slowing the
drill to a stop. If this procedure is not followed,
the tool will have a tendency to torque or twist
in your hands when the nut or bolt seats.
15°
CORRECT: Wire tips doing the work.
INCORRECT: Excessive pressure can cause wire breakage.
DRILLING METAL
There are two rules for drilling hard materials.
First, the harder the material, the greater the
pressure you need to apply to the tool. Second,
the harder the material, the slower the speed.
Here are a couple of tips for drilling in metal.
Lubricate the tip of the bit occasionally with
cutting oil except when drilling soft metals such
as aluminum, copper or cast iron. If the hole to
be drilled is fairly large, drill a smaller hole first,
then enlarge to the required size, it’s often
faster in the long run. Maintain enough
pressure to assure that the bit does not just
spin in the hole. This will dull the bit and greatly
shorten its life.
DRILLING MASONRY
Soft materials such as brick are relatively easy
to drill. Concrete however, will require much
more pressure to keep the bit from spinning. Be
sure to use carbide tip bits for all masonry work.
B
efore using an accessory,
be certain that its maximum
safe operating speed is not exceeded by the
nameplate speed of the tool. Do not exceed
the recommended wheel diameter.
SANDING AND POLISHING
Fine sanding and polishing require “touch”.
Select the most efficient speed.
When using polishing bonnets, always be sure
the excess string that secures the bonnet is
tucked well within the bonnet during operation.
