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.

remove any debris, then lightly grease with a
light oil or lubricant.
Insert accessory into the tool holder, while
twisting and pushing inward until it locks
automatically into place (Fig. 2).
To install hex round chisels, align flat on chisel
with alignment mark on tool holder, then push
chisel into tool holder until it locks automatically
into place. Pull outward on the accessory to
be certain it is locked into the tool holder
(Fig. 3).

TRIGGER CONTROLLED VARIABLE SPEED
Your tool is equipped with a variable speed
trigger switch. The tool speed can be controlled
from minimum to maximum nameplate rated
RPM by the pressure you apply to the trigger.
Apply more pressure to increase the speed and
release pressure to decrease speed (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.
TO LOCK TOOL “ON”: turn the selector dial to
the Hammering Only mode and squeeze the
trigger switch until it locks (Fig. 1).
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.
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 drilling or chiseling in hard
masonry material. Slower speeds work best to
reduce breakout when bits exit material being
drilled or chiseling material such as plaster or tile
(Fig. 1).
Regardless of the pressure applied on the
trigger, the tool will not operate any faster than
maximum speed setting selected.
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.

could startle the operator and lead to potential
injury.
"TURBO" FEATURE
In the "Hammer Only" mode power is
automatically increased 20% when the tool is
turned on to provide maximum chiselling
performance.
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.
SELECTOR LEVER
The selector lever allows the tool to be set for
various applications as listed in the following
chart, (Fig. 4).
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.

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

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.
Only genuine Bosch replacement brushes
specially designed for your tool should be
used.
