Read all instructions. Failure to follow all instructions listed below may
result in electric shock, fire and/or serious injury. The term "power tool"

in all of the warnings listed below refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

Work area safety

Keep work area clean and well lit.

Cluttered or 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 children and bystanders away while

operating a power tool. Distractions can

cause you to lose control.

Electrical safety
Power tool plugs must match the outlet.
Never modify the plug in any way. Do not

use any adapter plugs with earthed

(grounded) power tools. Unmodified plugs

and matching outlets will reduce risk of
electric shock.

Avoid body contact with earthed or
grounded surfaces such as pipes,

radiators, ranges and refrigerators. There

is an increased risk of electric shock if your
body is earthed or grounded.

Do not 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

for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil,

sharp edges or moving parts. Damaged or

entangled cords increase the risk of electric
shock.

When operating a power tool outdoors,

use an extension cord suitable for

outdoor use. Use of a cord suitable for

outdoor use reduces the risk of electric
shock.

Do not use AC only rated tools with a DC

power supply. While the tool may appear to

work, the electrical components of the AC

rated tool are likely to fail and create a
hazard to the operator.

If operating the power tool in damp
locations is unavoidable a Ground Fault

Circuit Interrupter (GFCI) must be used to
supply the power to your tool. GFCI and

personal protection devices like electrician's
rubber gloves and footwear will further

enhance your personal safety.

Personal safety

Stay alert, watch what you are doing and

use common sense when operating a
power tool. Do not use a power tool while

you are tired or under the influence of
drugs, alcohol or medication. A moment of

inattention while operating power tools may
result in serious personal injury.

Use safety equipment. Always wear eye
protection. Safety equipment such as dust

mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate

conditions will reduce personal injuries.

Avoid accidental starting. Ensure the
switch is in the off-position before

plugging in. Carrying power tools with your

finger on the switch or plugging in power
tools that have the switch on invites
accidents.

Remove any adjusting key or wrench
before turning the power tool on. A wrench

or a key left attached to a rotating part of the

power tool may result in personal injury.
Do not overreach. Keep proper footing

and balance at all times. This enables

better control of the power tool in unexpected

situations.

Dress properly. Do not wear loose

clothing or jewelry. Keep your hair,
clothing and gloves away from moving

parts. Loose clothes, jewelry or long hair can
be caught in moving parts.

If devices are provided for the connection

of dust extraction and collection facilities,
ensure these are connected and properly

used. Use of these devices can reduce dust-
related hazards.

-2-

Keep handles dry, clean and free from oil
and grease. Slippery hands cannot safely

control the power tool.

Power tool use and care

Do not force the power tool. Use the
correct power tool for your application.

The correct power tool will do the job better
and safer at the rate for which it was

designed.

Do not use the power tool if the switch
does not turn it on and off. Any power tool

that cannot be controlled with the switch is
dangerous and must be repaired.

Disconnect the plug from the power
source and/or the battery pack from the

power tool before making any
adjustments, changing accessories, or

storing power tools. Such preventive safety
measures reduce the risk of starting the

power tool accidentally.

Store idle power tools out of the reach of
children and do not allow persons

unfamiliar with the power tool or these
instructions to operate the power tool.

Power tools are dangerous in the hands of
untrained users.

Maintain power tools. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition

that may affect the power tools operation.
If damaged, have the power tool repaired

before use. Many accidents are caused by
poorly maintained power tools.

Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are

easier to control.

Use the power tool, accessories and tool
bits etc., in accordance with these
instructions and in the manner intended

for the particular type of power tool,
taking into account the working

conditions and the work to be performed.

Use of the power tool for operations different
from those intended could result in a
hazardous situation.

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.

Battery tool use and care

Recharge only with the charger specified
by the manufacturer. A charger that is

suitable for one type of battery pack may
create a risk of fire when used with another

battery pack.

Use battery tools only with specifically

designated battery packs. Use of any other

battery packs may create a risk of injury and

fire.

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 burns or a fire.

Under abusive conditions, liquid may be

ejected from the battery, avoid contact. If
contact accidentally occurs, flush with

water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the

battery may cause irritation or burns.
Ensure the switch is in the off position

before inserting battery pack. Inserting the
battery pack into power tools that have the

switch on invites accidents.

Service

Have your power tool serviced by a

qualified repair person using only identical

replacement parts. This will ensure that the

safety of the power tool is maintained.

Develop a periodic maintenance schedule

for your tool. When cleaning a tool be

careful not to disassemble any portion of
the tool since internal wires may be

misplaced or pinched or safety guard
return springs may be improperly

mounted. Certain cleaning agents such as

gasoline, carbon tetrachloride, ammonia, etc.
may damage plastic parts.

SAVETHESEINSTRUCTIONS

-3-

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 dr#i,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

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.

Position the tether clear of rotating bit.
Do not wrap the tether around your arm or

wrist. If you lose control and have the tether
wrapped around your arm or wrist, it may

entrap you and cause injury.

_ ome dust created by
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.

Battery/Charger

Before using battery charger, read all
instructions and cautionary markings on

(1) battery charger, (2) battery pack, and
(3) product using battery.

Use only the charger which accompanied
your product or direct replacement as

listed in the catalog or this manual. Do not

substitute any other charger. Use only Bosch
approved chargers with your product. See

Functional Description and Specifications.

Do not disassemble charger or operate the
charger if it has received a sharp blow,

been dropped or otherwise damaged in
any way. Replace damaged cord or plugs

immediately. Incorrect reassembly or

damage may result in electric shock or fire.
Do not recharge battery in damp or wet

environment. Do not expose charger to
rain or snow. If battery case is cracked or

otherwise damaged, do not insert into
charger. Battery short or fire may result.

Charge only Bosch approved rechargeable
batteries. See Functional Description and

Specifications. Other types of batteries may
burst causing personal injury and damage.

Charge battery pack in temperatures
above +40 degrees F (4 degrees C) and

below +105 degrees F (41 degrees C).

Store tool and battery pack in locations
where temperatures will not exceed 120

degrees F (49 degrees C). This is important

to prevent serious damage to the battery
cells.

Battery leakage may occur under extreme
usage or temperature conditions. Avoid

contact with skin and eyes. The battery

liquid is caustic and could cause chemical
burns to tissues. If liquid comes in contact

with skin, wash quickly with soap and water,
then with lemon juice or vinegar. If the liquid

contacts your eyes, flush them with water for
a minimum of 10 minutes and seek medical
attention.

Place charger on flat non-flammable
surfaces and away from flammable

materials when re-charging battery pack.

The charger and battery pack heat during
charging. Carpeting and other heat insulating

surfaces block proper air circulation which
may cause overheating of the charger and

battery pack. If smoke or melting of the case
are observed unplug the charger immediately

and do not use the battery pack or charger.

Use of an attachment not recom-
mended or sold by Bosch may result in a
risk of fire, electric shock or injury to
persons.

VARIABLE SPEED CONTROLLED

Your 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.

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.

GEAR SHIFTING

Your tool is equipped with two separate gear

ranges, low gear and high gear. Low gear

provides high-torque and slower drilling
speeds for heavy duty work or for driving

screws. High gear provides faster speeds for
drilling lighter work. To change speeds slide

switch, to the high or low position.
ATTENTION: If your tool appears to be

running, but the chuck will not turn, check to
make sure the gear shifting switch is pushed

fully into desired setting.

ADJUSTABLE CLUTCH
Your tool features 15 clutch settings. Output
torque will increase as the clutch ring, is

rotated from 1 to 15. 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.

BIT STORAGE ADAPTER

Your tool is equipped with a bit storage
adapter that will allow you to store a longer bit

if desired. To install bit adapter, remove bit

from standard storage area, then snap
adapter into it's place. To use, hold bit

adapter in place when removing bit (Fig. 1).

INSERTING BITS

Move reverse switch lever to the center
"OFF" position. Remove battery pack and

rotate the clutch ring to the drill bit symbol
" e,&_ ". Rotate the chuck sleeve counter-

clockwise viewing from chuck end, and open
chuck to approximate drill bit diameter. Insert

a clean bit up to the drill bit flutes for small
bits, or as far as it will go for large bits. Close

chuck by rotating the chuck sleeve clockwise
and securely tighten by hand.

IMPORTANT CHARGING NOTES

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 Bosch Service Center. See

"Tools, Electric" in the Yellow Pages for
names and addresses.

Note: Use of chargers or battery packs not
sold by Bosch will void the warranty.

Operating Tips

TETHER HOOK

The purpose of the tether hook is to secure
the tool when working on ladders,

scaffolding, or elevated heights to prevent
the tool from hitting the ground if accidentally

dropped. For best results, it is recommended
to use 1/4" braided nylon rope or similar

material.

You will extend the life of your bits and do

nearer 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.

DRIVING 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. 7) 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.

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

The adjustable screw drill accessory will do
all of these operations quickly and easily.

Screw drills are available for screw sizes No.

stone, concrete, plaster, cement and other
unusually hard nonmetals. Use continuous

heaw 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".

-14-

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.

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.

_ Before using an accessory,
safe operating speed is not exceeded by the

nameplate speed of the tool. Do not exceed
the recommended wheel diameter.

Fine sanding and polishing require "touch".
Select the most efficient speed.

Work with brushes requires high speeds.

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.

Preventive maintenance performed by
unauthorized personnel may result in

misplacing of internal wires and

components which could cause serious

hazard. We recommend that all tool service
be performed by a Bosch Factory Service

Center or Authorized Bosch Service Station.

SERVICEMEN: Disconnect tool and/or

charger from power source before servicing.

Be alert for battery packs that are nearing

their end of life. If you notice decreased
tool performance or significantly shorter

running time between charges then it is time

to replace the battery pack. Failure to do so
can cause the tool to operate improperly or

damage the charger.

Long term battery storage should be in

the discharged state. Battery packs last

longer and re-charge better when they are

stored discharged. Remember to fully re-
charge battery packs before using after

prolonged storage.

Your Bosch tool has been properly lubricated
and is ready for use.

The motor in your tool has been engineered
for many hours of dependable service. To

maintain peak efficiency of the motor, we
recommend it be examined every six months.

Only a genuine Bosch replacement motor
specially designed for your tool should be

used.

The brushes and commutator in your tool have

been engineered for many hours of

dependable service.

If your tool runs sporadically, loses power,
makes unusual noises or runs at a reduced

speed, check the brushes. To continue using
the tool in this condition will permanently

damage your tool.
Check both brushes. Usually the brushes will

not wear out simultaneously. If one brush is

worn out, replace both brushes.

Insert a screwdriver or similar object into the
red notch of the carbon brush and lift out the

brushes; note which way they face, so that the
brushes can be returned to their original

position. Clean the brush holder openings with
compressed air or a clean cloth and replace

the brushes and brush covers.
After replacing brushes the tool should be run

at no-load and run it freely at full speed for 2
minutes before using the tool. This will allow

the brushes to "seat" properly and will give

you more hours of life from each set of

brushes.
Only genuine Bosch replacement brushes

specially designed for your tool should be
used.

Cleaning

To avoid accidents, always

disconnect the tool and/or

charger from the power supply before

cleaning. The tool may be cleaned most
effectively with compressed dry air. Always

wear safety goggles when cleaning tools
with compressed air.

Ventilation openings and switch levers must
be kept clean and free of foreign matter. Do

not attempt to clean by inserting pointed
objects through opening.
