VARIABLE SPEED CONTROLLED
TRIGGER SWITCH
Your tool is equipped with a variable speed
trigger switch. The tool can be turned "ON" or
"OFF" by squeezing or releasing the trigger.
The speed can be adjusted from the minimum
to maximum nameplate RPM by the pressure
you apply to the trigger. Apply more pressure
to increase the speed and release pressure to
decrease speed (Fig. 1).
FORWARD/REVERSE SWITCH
The reversing switch is used to reverse rotation
of the bit (Fig. 1).
The reversing switch
should only be activated
when the motor is "OFF" and when bit is at a
complete standstill.
To use tool in "Forward" rotation move switch
torward the arrow that depicts forward.
"Reverse" the rotation of the bit move the
switch torward arrow that depicts reverse.

Operating Instructions
SELECTOR DIAL
The selector dial allows the tool to be set for
various drilling/hammer drilling applications.
Rotate the selector dial right or left depending
on the below applications (Fig. 10).
When using demolition or chipping bits such as
bull points, chisels, spades, gouges, etc. the
“Hammer Only” mode must be selected.
Do not operate the
selection dial until the
tool come to a complete stop.
Shifting during
rotation of the chuck can cause damage to the
tool.
"VARIO-LOCK"- SELECTOR DIAL
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.
Rotate 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.
VIBRATION DAMPER HANDLE /
HAMMER MECHANISM
The integrated vibration damper in the main
handle and hammer mechanism reduces
vibrations (Fig. 1).
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.
TOOL TIPS
Following a few simple tips will reduce wear
on the tool and the chance of injury to the
operator.
The high efficiency available from the BOSCH
Rotary Hammer can only be obtained if sharp
and undamaged drilling tools are used. Note
that the costs for maintaining sharp drilling
tools are more than offset by the time lost in
operating dull drilling tools.
