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

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
!
When the power cord is
u
nplugged from the mains
outlet or when branch-circuit power is
interrupted, the electronic controller will
automatically reset the tool to maximum
speed and impact force.
Unexpected starting
at maximum operating speed and impact force
could startle the operator and lead to potential
injury.
"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
(Fig. 7).
VARIABLE SPEED DIAL
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 (Fig. 8).
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 virtually constant between
no-load and load conditions.

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 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.

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 (Fig. 8).
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.
Only genuine Bosch replacement brushes
specially designed for your tool should be used.
