Read and understand all instructions. Failure to follow all instructions
listed below, may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
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.

Rotary Hammer Safety Rules
Hold tools by insulated gripping surfaces
when performing an operation where the
cutting tool may contact hidden wiring or it
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.
Wear ear protectors when using the tool for
extended periods. Prolonged exposure to
high intensity noise can cause hearing loss.
Use a metal detector to determine if there
are gas or water pipes hidden in the work
area or call the local utility company for
assistance before beginning the operation.
Striking or cutting into a gas line will result in
explosion. Water entering an electrical device
may cause electrocution.
Always use the side handle for maximum
control over torque reaction or kick-back.
Never attempt to operate this tool with one
hand. The slip clutch engages if you firmly
control the tool during a 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. Safety goggles or eye
protection will help deflect fragments of the
material that may be thrown toward your face
and eyes. Dust generated or gases released
from the material you are cutting (i.e. asbestos
insulated pipes, radon) may cause respiratory
difficulties.
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.
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.

Position the cord clear of rotating bit. Do
not wrap the cord around your arm or
wrist. If cord becomes entangled with the
spinning bit it could entrap you causing
serious personal injury.
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 hammer body
will tend to twist in the opposite direction as
the bit is rotating. (Note use only if your tool
has reversing feature.)
Do not strike the bit with a handheld
hammer or sledge hammer when
attempting to dislodge a bound or jammed
bit. Fragments of metal from the bit could
dislodge and strike you or bystanders.
Never place the tool down until the bit or
accessory have come to a complete stop.
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.
Do not run the tool while carrying it at your
side. The spinning drill bit may 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.

TRIGGER "ON-OFF" SWITCH
To turn the tool “ON” squeeze the trigger
switch. To turn the tool “OFF”, release the
trigger switch, which is spring loaded and
will return to the “OFF” position
automatically.
To increase switch life, do not turn switch on
and off while tool is under load.
VARIABLE SPEED DIAL
Your tool is equipped with a variable speed
dial. The impact rate (BPM) and rotating
speed (RPM) can be varied according to the
type of work being performed by setting the
variable speed dial to the selected setting.
The chart below will help you to determine
which setting to use for your application.
However, a pre-test will determine the best
speed setting, as the chart is intended only
as a guide. Once the proper setting is
determined the impact rate and rotating
speed is kept constant by means of the
"Electronic Feedback Circuitry". The variable
speed dial can be adjusted while the motor
is running with the tool free from work,
allowing the operator to adjust the impact
rate and rotating speed according to the
actual application.
ELECTRONIC FEEDBACK
CIRCUITRY (EFC)
The internal electronic feedback system
provides a "soft start", which will reduce the
stresses that occur from a high torque start.
The system also helps to keep the preselected impact rate and rotating speed
virtually constant between no-load and load
conditions.
INSTALLING ACCESSORIES
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 acessory to be certain it
is locked into the tool holder (fig. 2).
NOTE: You may notice some “wobble” or
“run out” of the bit when run in a no load
condition. This is due to the quick change
SDS tool holder assembly. However, once the
bit has a load placed upon it, the bit
automatically centers itself to produce an
accurate hole.
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.
REMOVING ACCESSORIES
Accessories may be hot
after use. Avoid contact
with skin and use proper protective gloves or
cloth to remove.
To remove an accessory, pull and hold
locking sleeve backward and pull bit
forward. All accessories should be wiped
clean after removing.

SELECTOR DIAL
The selector dial allows the tool to be set for
various applications as listed in the following
chart, (Fig. 3).
When using demolition or chipping bits such
as bull points, chisels, spades, gouges, etc.
the “Hammer Only” mode must be selected.
SELECTOR DIAL - “VARIO-LOCK”
Adjusting the Vario-Lock: The vario-lock can
be set in any one of thirty-six (10˚ increments)
positions. Choose a position which is best
suited for your operation.
Depress release button and turn the
selector dial, to the “vario-lock” setting.
Next, rotate the locking sleeve, along with
the accessory, to the desired position. Then
turn the selector dial to the “hammer only”
setting and slightly turn the locking sleeve to
have it automatically lock into a definite
position.
QUICK CHANGE SDS TOOL-HOLDER
This tool features a removable tool holder
which allows a rapid change from the SDS
tool holder, which is
standard equipment,
to optional accessory
tool holders.
To remove the SDS
tool holder assembly,
rotate the locking
sleeve in the rotational
direction of the bit
(clockwise) until it
stops. When the locking sleeve stops, pull
the whole SDS tool holder assembly
outward until it pulls free from the tool’s
spindle mount.
To install an optional accessory tool holder
or re-install the SDS tool holder, align the
steel balls inside the accessory with the
grooves in the front of the tool’s spindle
mount. Next rotate the accessorie’s locking
sleeve in the rotational direction of the bit
(clockwise) until it stops. When the locking
sleeve stops, release it and the accessory
tool holder will automatically rotate back and
lock itself into place.
SLIP CLUTCH
The tool has a internal pre-set slip clutch.
The output spindle will stop rotating if the
accessory binds and overloads the tool.
AUXILIARY HANDLE
The tool must be supported with the
auxiliary handle, which can be swiveled 360˚.
To reposition and/or swivel the handle,
loosen the hand grip, move the handle to the
desired position along the barrel and
securely retighten the hand grip.
DEPTH GAUGE
Your drilling depth can be pre-set and/or
repeated by using the depth gauge.
Setting depth: After the auxiliary handle is
installed, slide the depth gauge to desired
depth and securely tighten wing knob.
TOOL TIPS
For the best penetration rates in concrete,
run the tool with a steady pressure, but do
not use excessive force as this will decrease
the efficiency of the tool.
All grease packed hammers require a short
period of time to warm up. Depending on the
room temperature, this time may vary from
approximately 15 seconds (90˚F) to 2
minutes (32˚F). A new hammer requires a
break-in period before full performance is
realized. This period may require up to 5
hours of operation.
A rotary hammer is likely to be the most
expensive portable tool at the construction
job. The long wear and efficient operation of
the BOSCH hammers will more than justify
the cost for tools of this type. As earlier
pointed out, sharp accessories as well as
clean air vents are necessary for efficient
operation. Establish and follow a set
maintenance program.

If an extension cord is
necessary, a cord with
adequate size conductors that is capable
of carrying the current necessary for your
tool must be used. This will prevent
excessive voltage drop, loss of power or
overheating. Grounded tools must use 3wire extension cords that have 3-prong
plugs and receptacles.
