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
Do not abuse the cord. Never use the cord to carry the tool. Keep cord away from heat, oil, sharp edges, or moving parts. Replace damaged cords immediately. Damaged cords may create a
fire.
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

Cordless Rotary Hammer Safety Rules
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.
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 recom-
mended 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 qualified repair personnel. Service 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 tools by insulated gripping surfaces when performing an operation where the cutting tool 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.
Wear ear protectors when using the tool for extended periods. Prolonged exposure
to high intensity noise can cause hearing loss.
Before changing accessories remove battery pack. Accidental starting may
occur because battery tools with a battery inserted are in the operative condition.
Do not use dull or damaged bits and accessories. Dull bits or accessories can
frequently bind in the work causing a torque reaction.
Always wear safety goggles or eye protection when using this tool. Use a dust mask or respirator for applications which generate dust.
Always use the auxiliary handle for maximum control over torque reaction or kick-back. Never attempt to operate this tool with one hand. The slip clutch engages
only if you apply sufficient force to the tool during a torque reaction or kick-back.
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 hammer body will tend to twist in the opposite direction as the bit is rotating.
Avoid being caught between the rotary hammer and walls or posts. Should the bit
become bound or jammed into the work, the reaction torque of the rotary hammer could crush your hand or leg.
Do not strike the bit with a handheld hammer or sledge tool when attempting to dislodge a bound or jammed bit.
Fragments of metal from the bit could dislodge and strike you or bystanders.
Do not run the tool while carrying it at your side. The spinning drill bit may become
entangled with clothing and injury may occur.

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 Cordless Rotary Hammer or direct replacement as listed in the catalog or this manual. Do not substitute any other
charger. Use only Bosch battery charger Nos. BC015 & BC016 with your Cordless Rotary Hammer.
Do not disassemble charger or operate the charger if it has received a sharp blow, been dropped or otherwise damaged in any way. 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 Nos. BAT019, BAT020 and BAT021, rechargeable batteries with the above listed charger. 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 do not go below 32 degrees F (0 degrees C) or 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 recom­mended or sold by Bosch may result in a risk of fire, electric shock or injury to persons.
Battery/Charger
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.
Never place the tool down until the bit or accessory have come to a complete stop.
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.
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.

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.
The tool has an internal preset clutch. The clutch is set such that sufficient force is transmitted to the bit for most drilling conditions but it will slip when bit binds in the hole or the tool is overloaded. Be aware that due to required clutch setting, you may experience a torque reaction an instant before the clutch slips. This torque reaction will twist the body of the rotohammer in the opposite direction as the bit rotates, i.e.,
counterclockwise. As clutch is slipping, the bit will most likely stop rotating. When the binding force on the bit is removed the clutch automatically resets. If you experience bit binding and clutch begins to slip, immediately turn the tool "OFF" and correct the condition leading to the bit binding.
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.

The battery is equipped with a charged condition indicator. This indicator shows the charged condition of the battery during the working process.
By pressing the button ON, the charged condition can also be checked when the battery is removed or when the machine is not in use. After approx. 4 seconds, the charged indicator switches off automatically.
When the last indicating element blinks (0 ­10%), the battery is nearly discharged and must be recharged.
To maintain the indicator accuracy, occasionally discharge the battery until the speed of the machine is distinctly reduced and the charged condition indicator goes off completely.
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.
Clean the insert shank end of the accessory to remove any debris, then lightly grease with a light oil or lubricant.
Insert accessory into the tool holder through the dust shield, while twisting and pushing inward until it locks automatically into place. Pull outward on the accessory to be certain it is locked into the tool holder.
NOTE: The high efficiency available from the rotary hammers can only be obtained if sharp and undamaged accessories are used. The “cost” to maintain sharp and undamaged accessories is more than offset by the “time saved” in operating the tool with sharp accessories.
The selector dial allows the tool to be set for various drilling applications. Shift the dial right or left depending on the below applications.
Do not operate the
selection dial until the tool come to a complete stop. Shifting during rotation of the chuck can cause damage to the tool.
Do not use demolition or chipping bits such as bull points, chisels, spades, gouges, etc.
Drill only action: For drilling in woods, metals, plastics or other non concrete materials.
Drill with hammer action: For drilling in concrete, asphalt, tile or other similar hard materials.

REMOVING ACCESSORIES
RELEASING AND INSERTING BATTERY PACK
PROTECTIVE
CAP
BATTERY PACK
LOCKING BUTTON
Plug charger cord into your standard power outlet, then insert battery pack into charger.The charger’s green indicator light will begin to “BLINK”. This indicates that the battery is receiving a fast charge. Fast­charging will automatically stop when the battery pack is fully charged.
When the indicator light stops “BLINKING” (and becomes a steady green light) fast charging is complete, and an acoustical signal sounds for a period of approximately 2 seconds which indicates that the battery is completely charged.
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 charging several batteries in sequence, the charge time may slightly increase.
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.

WARNING
BM 1619929426 8/01 8/2/01 1:19 PM Page 10
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 32˚F (0˚C) and 140˚F (60˚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 heavy use). When the battery temperature returns to between 32˚F (0˚C) and 140˚F (60˚C), the charger will automatically begin charging.
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.
IMPORTANT CHARGING NOTES
If the indicator lights are “OFF”, the charger is not receiving power from power supply outlet.
If the green indicator light is “ON”, the charger is plugged in but the battery pack is not inserted, or the battery pack is fully charged and is
being trickle charged.
If the green indicator light is “BLINKING”, the battery pack is being fast-charged. Fast-charging will automatically stop when the
battery pack is fully charged.
If the red indicator light is “ON”, the battery pack is too hot or cold for fast-charging. The charger will
switch to trickle charge, until a suitable temperature is reached, at which time the charger will switch automatically to fast-charging.
If the red indicator light is
“BLINKING”, an acoustical signal
will sound for a period of 2 seconds
which indicates the battery pack cannot accept a charge or the contacts of the charger or battery pack are contaminated. Clean the contacts of the charger or battery pack only as directed in these operating instructions or those supplied with your tool or battery pack.

DRILLING WOOD OR PLASTIC
If backing block is not used, ease up on the pressure just before the bit breaks through the wood to avoid splintering. Complete the hole from the opposite side immediately after the point breaks through. If bit binds, reverse the drilling operation to help remove the bit from the work.
DRILLING METAL
Make a center punch in the material for easier starting. Use enough pressure to keep the bit cutting. If the bit is allowed to merely spin in the hole, it will become dull within a short time. When drilling a larger hole, it is faster and easier on your power pack to first make a smaller hole and enlarge it to the
required size. Lubricate the tip of the bit occasionally with CUTTING OIL for easier metal drilling. If bit binds, reverse the drilling to help remove the bit from the work.
DRILLING MASONRY
Use carbide-tipped masonry bit for cinder block, mortar, common brick, soft stone and other materials. The amount of pressure to be used is dependent upon the type of material being drilled. Soft materials require less pressure while the hard materials need more pressure to prevent the drill bit from spinning.
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 may void the warranty.
