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
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.

BIT HOLDER
This tool features a removable bit holder,
which allows a rapid exchange of the SDS-
plus bit holder should it become damaged.
To remove the SDS-plus
bit holder assembly,
r
otate the 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
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.
