SAVE ALL WARNINGS AND INSTRUCTIONS

FOR FUTURE REFERENCE

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.

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.

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.

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 influenceof drugs,

alcohol or medication. A moment of inattention

while operating power tools may result in

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 contactwith earthed or grounded
surfaces such as pipes, radiators, ranges

and refrigerators. There isan 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.

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

Interrupter (GFCI) protected supply. Use of

a GFCI reduce the risk of electric shock.

GFCl and personal protection devices like
electrician's rubber gloves and footwear will
further enhance your personal safety.

serious personal injury.
Use personal protective equipment. Always

wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard

hat, or hearing protection used for appropriate
conditions will reduce personal injuries.

Prevent unintentional starting. Ensure the

switch isin the off-position before connecting
to power source and / or battery pack,

picking up or carrying the tool. 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 dust collection can reduce dust-

related hazards.

-2-

........\ii]7.......

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

bitsetc. in accordancewith these instructions,
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

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.

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 power 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.

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.

Safety Rules for Cordless Hammer Drills

Wear ear protectors with impact drills.

Exposure to noise can cause hearing loss.
Use auxiliary handles supplied with the

tool. Loss of control can cause personal injury.

Hold power tools 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.

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 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.

Wear ear protectors when using the tool for
extended periods. Prolonged exposure to

high intensity noise can cause hearing loss.

Always use auxiliary handle for maximum
control over torque reaction or kick-back.

High torque 3/8" and larger chuck capacity

drills are equipped with auxiliary handles.
Always wear safety goggles or eye

protection when using this tool. Use a dust
mask or respirator for applications which

generate dust.

Use thick cushioned gloves and limit the

exposure time by taking frequent rest

periods. Vibration caused by hammer-drill

action may be harmful to your hands and
arms.

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 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 tool while carrying it at your
side. A spinning drill bit could become

entangled with clothing and injury may result.

_ 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. De net

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

+32 degrees F (0 degrees C) and below

+113 degrees F (45 degrees C). Store tool

and battery pack in locations where
temperatures will not exceed 120 degrees F

(49 degrees C). This is importantto 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. 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 will result in a
risk of fire, electric shock or injury to

persons.

Battery Care

When batteries are not in nails, screws, keys, etc. Fire or injury may

IMPORTANT CHARGING NOTES

1. The charger was designed to fast charge
the battery only when the battery temperature

is between 32°F (0°C) and 113°F (45°C). If the
battery pack is too hot or too cold, the charger

will not fast charge the battery. (This may
happen if the battery pack is hot from hea W

use). When the battery temperature returns to
between 32°F (0°C) and 113°F (45°C), the

charger will automatically begin charging.

2. 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.

3. Remember to unplug charger during storage
period.

4. 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.

complete. The battery pack is fully charged and

can be removed from the charger.
The battery pack may be used even though the

light may still be blinking. The light may require
more time to stop blinking depending on
temperature.

The purpose of the green light is to indicate that
the battery pack is fast-charging. It does not

indicate the exact point of full charge. The light
will stop blinking in less time if the battery pack
was not completely discharged.

When you begin the charging process of the
battery pack, a steady red light could also mean

the battery pack is too hot or too cold.
Fast charging is only possible when the

temperature range of the battery pack is
between 32°F (0°C) and 113°F (45°C). When

needed, the internal fan of the charger will turn
on to aid the charging process and speed.

As soon as the battery pack reaches the
correct temperature range, the battery charger

will automatically switch to fast charging.
If the red indicator light is "BLINKING", the

battery pack cannot accept a charge.

Operating Tips

You will extend the life of your bits and do
nester 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

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. 11) 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

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

drills are available for screw sizes No. 6, 8, 10
and 12.

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".

-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.

When using polishing bonnets, always be sure
the excess string that secures the bonnet is

tucked well within the bonnet during operation.

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

be certain that its maximum

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.

PARTS INSIDE. Preventive

maintenance performed by unauthorized
personnel may result in misplacing of
internal wires and components which

could cause serious hazard. We recom-

mend 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.

BATTERIES

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.

TOOL LUBRICATION

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

D.C. MOTORS

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.

CARBON BRUSHES

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.

To check brushes: Disconnect battery pack
from tool. Remove brush cover at the rear part

of housing by loosening screws (Fig. 12).

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.
