WARNING
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 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
DUAL FUNCTION TRIGGER SWITCH
To turn the tool “ON” in the Drilling/
Hammering mode, 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
(Fig. 1).
Your tool is also equipped with a "Lock-ON"
feature when the selector dial is in the
Hammering Only mode which allows
continuous operation without holding the
trigger (Fig. 1).
TO LOCK TOOL “ON”: turn the selector dial
to the Hammering Only mode and 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.
VARIABLE SPEED DIAL
Your tool is equipped with a variable speed
dial (Fig. 1). 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, allowing the operator to
adjust the impact rate and rotating speed
according to the actual application.
In the "Hammer Only" mode power is
automatically increased 20% when the tool is
turned on to provide maximum chiselling
performance.
ELECTRONIC FEEDBACK 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.
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.

SELECTOR LEVER
The selector lever 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 LEVER - “VARIO-LOCK”
The vario-lock can be set in any one of twelve
positions (30˚ increments). Choose a position
which is best suited for your operation. The
Vario-Lock position is intended for use with
chipping bits such as bull points, spades,
gouges, etc.
Turn the selector lever, to the “vario-lock”
setting. Next, rotate the locking sleeve,
along with the accessory, to the desired
position. Then turn the selector lever to the
“hammer only” setting and slightly turn the
locking sleeve to have it automatically lock
into a definite position.
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 (Fig. 1).
"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.

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.
The brushes and commutator in your tool
have been engineered for many hours of
dependable service. To maintain peak
efficiency of the motor, we recommend every
two to six months the brushes be examined.
