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.

T
he articulating auxiliary handle can be
turned to any position. Loosen the knurled
nut, rotate the handle around the tool to the
desired position and securely tighten the
knurled nut (Fig 1).
INSTALLING ACCESSORIES
Clean the insert shank end of the accessory
to remove any debris, then lightly grease with
a light oil or lubricant. If work is to be done
where the accessories are changed
frequently and laid in dirt, sand or concrete
dust, it is best not to grease the shank after
wiping clean.

clamping element by 180°. Mount the handle
in reverse order.
To lock
standard air steel in place, lower
the tool retainer lever all the way down and
around the bottom and raise lever all the way
up to the opposite side. To lock, insert air

Operating Instructions
ROCKER “ON/OFF” SWITCH
TO TURN THE TOOL "ON" depress the
dust-protected switch to the number “I”
position.
TO TURN THE TOOL "OFF": depress switch
to the number “0” position (Fig. 1).
For low temperatures, the machine reaches
the full impact rate only after a certain time.
This start-up time can be shortened by
striking the chisel in the tool against the floor
one time.
VIBRATION CONTROL HANDLE
While working, hold the tool with both hands
by the handle. The handle can move upward
and downward around its axis by approx. 30
mm. This has a damping effect against
vibrations (Fig. 4).

"TOOL TIPS"
The tool may be switched on with either
hand. Balance the tool with both hands and
rest the tool on the hip.
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. Start chipping with
the tool in a straight in position until the
surface to be broken is chipped. Draw the
hammer back at an angle of 60˚ with the
surface to be broken. Apply only enough
force to keep the tool weight on the
accessory

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

by a Bosch Factory Service Center or Authorized Bosch Service Station.
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.
Your tool is equipped with a Pop-out brush

Avoid no load running of the tool. No load or
"empty blows" is the most damaging factor to
any impact hammer.
As earlier pointed out, sharp accessories as
well as clean air vents are necessary for
efficient operation. Establish and follow a set
maintenance program.
BEARINGS
Every second brush change, the bearings
should be replaced at Bosch Factory Service
