AUTO-MAX ™
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.
When the power cord is
! WARNING
unplugged from the mains
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 chiseling in hard masonry
material. Slower speeds work best for
chiseling material such as plaster or tile.
CONSTANT RESPONSE CIRCUITRY
The internal electronic feedback system
provides a "soft start", which will reduce the
stresses that occur from a high torque start.
The system also helps to keep the pre-
selected impact rate and rotating speed
virtually constant between no-load and load
conditions.
INSTALLING ACCESSORIES
Clean the insert shank end of the accessory
to remove any debris, then lightly grease with
a light oil or lubricant.

accessories.
