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.

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

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 chemicallytreated 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.

Operating Instructions
TRIGGER "ON-OFF" SWITCH
To turn the tool “ON” squeeze and hold the
trigger switch. To turn the tool “OFF”,
release the trigger switch, which is spring
loaded and will return to the “OFF” position
automatically.
Your tool is also equipped with a "Lock-ON"
feature which allows continuous operation
without holding the trigger.
TO LOCK TOOL “ON”:squeeze the trigger
switch until it locks.
TO TURN TOOL: “OFF“ press the trigger
release switch and the trigger will return to
the “OFF” position automatically.
To increase switch life, do not turn switch on
and off while tool is under load.
The patented Bosch Auto-Max system
insures that each time your tool is plugged in
and receiving power, it will operate at
maximum speed and impact force.
WARNING

at maximum operating speed and impact force
could startle the operator and lead to potential
injury.
Your tool is equipped with a variable speed
dial. The speed and impact force can be
adjusted by rotating the dial. Higher speeds
and impact force work best for faster
penetration when chiseling in hard masonry
material. Slower speeds work best for
chiseling material such as plaster or tile.
CONSTANT RESPONSE CIRCUITRY
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.
Clean the insert shank end of the accessory
to remove any debris, then lightly grease with
a light oil or lubricant.

LOCKING SLEEVE
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

remove.
To remove an accessory, pull and hold
locking sleeve backward and pull bit forward.
All accessories should be wiped clean after
removing.
"VARIO-LOCK"- SELECTOR RING
The vario-lock selector ring can be set in any
one of twelve (30˚ increments) positions.
Choose a position which is best suited for
your operation. To adjust, pull the selector
ring forward and hold firmly, then turn both
the accessory and the selector ring to the
desired position. Release the selector ring
and turn the accessory slightly until it locks in
place.

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.
When you plug your tool into the power
source, the power indicator light will go “ON”
indicating the tool is receiving power.
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.

recommend that all tool service be performed
by a Bosch Factory Service Center or Authorized Bosch Service Station.
SERVICE REMINDER LIGHT
When the service reminder light lights up or
blinks, this will indicate that the cut-out
carbon brushes will switch off the tool in
approximately 8 hours. After that period, the
light will go off and the tool will stop running.
The tool must then be sent to a service
center for service.
Your Bosch tool has been properly lubricated
and is ready to use. It is recommended that
tools with gears be regreased with a special
gear lubricant at every brush change.

CARBON BRUSHES
All 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.
An electric 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.
dependable service. To maintain peak
efficiency of the motor, we recommend every
two to six months the brushes be examined.
Only genuine Bosch replacement brushes
specially designed for your tool should be
used.
BEARINGS
After about 300-400 hours of operation, or at
every second brush change, the bearings
should be replaced at Bosch Factory Service
Center or Authorized Bosch Service Station.
Bearings which become noisy (due to heavy
load or very abrasive material cutting) should
be replaced at once to avoid overheating or
motor failure.
REPLACEMENT OF CORD AND
CARBON BRUSHES
Your tool is designed to provide a qualified
service technician optimal access to replace
the carbon brushes and the cord. This
provides the service technician the ability to
replace these components without the need
of disassembling the entire tool housing.
