being drilled or chiseling material such as
plaster or tile.
Regardless of the pressure applied on the
trigger, the tool will not operate any faster than
maximum speed setting selected.
"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 pre-
selected 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

used for drilling with solid
carbide bits and core bits
"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

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.
POWER INDICATOR LIGHT
When you plug your tool into the power
source, the power indicator light will go
"ON" indicating the tool is receiving power.

Vario-Lock:
allows chisel to be set in
one of 12 positions
(right or left "0" position)
realized. This period may require up to 5
hours of operation.
A combination 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.
