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
Double Insulated tools are equipped with a
polarized plug (one blade is wider than the
other.) This plug will fit in a polarized outlet
only one way. If the plug does not fit fully
in the outlet, reverse the plug. If it still does
not fit, contact a qualified electrician to
install a polarized outlet. Do not change
the plug in any way.
Double Insulation
eliminates the need for the three wire
grounded power cord and grounded power
supply system.
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.
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.
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.
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.

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 (fig. 2).
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 (Fig. 3).
Operating Instructions
VARIABLE SPEED CONTROLLED
TRIGGER SWITCH
Your tool is equipped with a variable speed
trigger switch. The tool can be turned "ON" or
"OFF" by squeezing or releasing the trigger.
The speed can be adjusted from the minimum
to maximum nameplate RPM by the pressure
you apply to the trigger. Apply more pressure
to increase the speed and release pressure to
decrease speed.
REVERSING SWITCH LEVER
(Models 11224 & 11228 only)
The reversing switch lever is located above
the trigger switch and is used to reverse
rotation of the bit.
The reversing switch should
only be activated when the
motor is "OFF" and when bit is at a complete
standstill.
To use tool in "Forward" rotation move lever
to left side of tool, to "Reverse" the rotation of
the bit move the lever to the right side of the
tool.
SELECTOR DIAL
The selector dial allows the tool to be set for
various applications as listed in the chart.

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
Following a few simple tips will reduce wear
on the tool and the chance of injury to the
operator.
The high efficiency available from the
BOSCH Rotary Hammer can only be
obtained if sharp and undamaged drilling
tools are used. Note that the costs for
maintaining sharp drilling tools are more than
offset by the time lost in operating dull drilling
tools.
All grease packed hammers require a short
time to warm up. Depending on the
temperature, this time will vary from
approximately 15 seconds (90° F) to 2
minutes (32° F). The tool will exert its full
power and hammering action after the heat
from impact hammering has spread,
softening the grease.
CARBIDE TIPPED BITS
Used for drilling stone, concrete, cement,
brick, cinder block and other unusually hard
non-metals. The Rotary Hammer is designed
for “SDS” Carbide Tipped Bits up to 3/4 inch
diameter.
3 JAW CHUCK
The 3 Jaw Chuck with SDS Shank Adaptor
accessory can convert your tool for use with
straight shank bits.
You will extend the life of your bits and do
neater work if you always put the bit in contact
with the workpiece BEFORE pulling the
trigger. During operation, hold the drill firmly
and exert moderate, steady pressure. Too
much pressure at low speed will stall the
hammer. Too little pressure will keep the bit
from cutting and cause excess friction by
sliding over the surface. This can be
damaging to the drill and bit.
Shanks of all drill bits should be wiped clean
prior to using and immediately after removing.
RECALL THESE INSTRUCTIONS FOR
SAFE OPERATION:
1. Some materials require slow drilling
speeds; whereas, others require higher speed
to produce the best results.
2. All work must be supported or secured
before drilling and steady, even pressure
applied in line with the drill bit.
3. As the drill bit cuts through the opposite
side, reduce the pressure and continue
running the drill as the bit is withdrawn.
Materials such as glass, porcelain, ceramics,
tiles, plastics, etc., should be drilled at low
speeds with specially designed drill bits and
lubricants.
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.

* Auxiliary Handle
* Carrying case
(*= standard equipment)
(**= optional accessories)
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 3-wire
extension cords that have 3-prong plugs and
receptacles.
NOTE: The smaller the gauge number, the
heavier the cord.
