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
VARIABLE SPEED CONTROLLED
Your tool is equipped with a variable speed
trigger switch. The tool speed can be
controlled from the minimum to the maximum
nameplate RPM by the pressure you apply to
the trigger. Apply more pressure to increase
the speed and release pressure to decrease
speed. This accurate speed control enables
you to drill without center punching. It also
permits you to use as a power screwdriver.
Accessories are available for driving screws
as well as running bolts and nuts.
INSTALLING SDS-plus®ACCESSORIES
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 bit 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 bit 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.
REMOVING SDS-plus®ACCESSORIES
!
WARNING
and use proper protective gloves or cloth to
remove.
To remove an accessory, pull and hold locking
sleeve backward and pull bit forward. All
accessories should be wiped clean after
removing.

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.
Depress release button and 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.

QUICK CHANGE SDS-plus®BIT HOLDER
This tool features a removable bit holder,
which allows a rapid exchange of the SDSplus bit holder should it become damaged.
To remove the SDS-plus
bit holder assembly,
r
otate the locking sleeve
LOCKING SLEEVE
in the rotational direction
of the bit (clockwise) until
it stops. When the
locking sleeve stops, pull
the whole SDS-plus bit
holder assembly outward
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 can 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.
DEPTH GAUGE
Your drilling depth can be pre-set and/or
repeated by using the depth gauge.
Setting depth: After the auxiliary handle is
installed, slide the depth gauge to desired
depth and securely tighten wing knob.
"TOOL TIPS"
For the best penetration rates in concrete,
run the tool with a steady pressure, but do
until it pulls free from the tool’s spindle
mount.
To re-install SDS-plus bit holder, align the
steel balls inside the accessory with the
grooves in the front of the tool’s spindle
mount. Next rotate the bit holder’s locking
s
leeve (clockwise) until it stops. Then press
slightly inward towards back of tool until it
locks in place.
After installing the bit holder always pull
outward on the bit holder to be certain it is
locked onto to spindle mount.
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.
