SELECTOR DIAL
The selector dial 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.
= drilling only:
used for... drilling
wood, steel, etc.
= drilling/hammering:
used for... drilling
concrete
= hammering only:
used for... light
chipping work
= vario-lock:
allows for 36 desired
positions of "hammer"
accessories
SELECTOR DIAL - "VARIO-LOCK"
Adjusting the Vario-Lock: The vario-lock can
be set in any one of thirty-six (10˚ increments)
positions. Choose a position which is best
suited for your operation.
Depress release button and turn the
selector dial, to the "vario-lock" setting.
Next, rotate the locking sleeve, along with
the accessory, to the desired position. Then
turn the selector dial to the "hammer only"
setting and slightly turn the locking sleeve to
have it automatically lock into a definite
position.
QUICK CHANGE SDS TOOL-HOLDER
This tool features a removable tool holder
which allows a rapid change from the SDS
tool holder, which is
standard equipment,
to optional accessory
tool holders.
To remove the SDS
tool holder assembly,
rotate the locking
sleeve in the rotational
direction of the bit
(clockwise) until it

stops. When the locking sleeve stops, pull
the whole SDS tool holder assembly
outward until it pulls free from the tool's
spindle mount.
To install an optional accessory tool holder
or re-install the SDS tool holder, align the
steel balls inside the accessory with the
grooves in the front of the tool's spindle
mount. Next rotate the accessorie's locking
sleeve in the rotational direction of the bit
(clockwise) until it stops. When the locking
sleeve stops, release it and the accessory
tool holder will automatically rotate back and
lock itself into place.
The tool has a internal pre-set slip clutch.
The output spindle will stop rotating if the
accessory binds and overloads the tool.
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.
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.
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.
LOCKING SLEEVE
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.
