after use. Avoid contact
with skin 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.
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.
TRIGGER CONTROLLED VARIABLE SPEED
Your tool is equipped with a variable speed
trigger switch. The tool speed can be
controlled from minimum to maximum
nameplate rated RPM by the pressure you
apply to the trigger. Apply more pressure to
increase the speed and release pressure to
decrease speed (Fig. 1).
Your tool is also equipped with a "Lock-ON"
feature when the selector dial is in the
Hammering Only mode which allows
continuous operation without holding the
trigger.
TO LOCK TOOL "ON": turn the selector dial
to the Hammering Only mode and squeeze
the trigger switch until it locks.
TO TURN TOOL: "OFF" press the trigger
release switch and the trigger will return to
the "OFF" position automatically.
To increase switch life, do not turn switch on
and off while tool is under load.

The patented Bosch Auto-Max system
insures that each time your tool is plugged in
and receiving power, it will operate at
maximum speed and impact force.
WARNING
!
outlet or when branch-circuit power is
interrupted, the electronic controller will
automatically reset the tool to maximum
speed and impact force. Unexpected
starting at maximum operating speed and
impact force could startle the operator and
lead to potential injury.
VARIABLE SPEED DIAL
Your tool is equipped with a variable speed
dial. The speed and impact force can be
adjusted by rotating the dial. Higher speeds
and impact force work best for faster
penetration when drilling or chiseling in hard
masonry material. Slower speeds work best
to reduce breakout when bits exit material
