Functional Descriptions
Automatic Restart Protection:
Helps prevent accidental startups after power
has been interrupted, e.g. the tool was
unplugged with the switch locked in the on
position. To resume operation, turn on/off
switch to the off position, then restart the
tool. See the chart under Fig. 1 and Fig. 2 to
find out which grinders are equipped with the
Automatic Restart Protection.
Overload Protection:
Helps protect tool from excessive heat that
may damage motor. If tool stops or slows
during operation, allow motor to cool for 30
seconds by running no-load. If the overload
protection stops the tool repeatedly,
excessive force is causing the tool to
overload. Stop excessive force and readjust
work piece to reduce force applied.

Unexpected run down

Your grinder is equipped with an automatic
electric brake which is designed to rapidly
stop the accessory from spinning after you
release the side trigger switch. This feature
helps improve jobsite productivity.
Braking starts once the power is turned off.
The brake requires a charged battery to
function. Stopping time will vary depending
on, among other factors, accessory used,
and number of actuations. The electric
brake of your grinder has been designed for
a high degree of reliability, but unexpected
circumstances such as contamination or
failure of the motor’s components can
cause the brake to not activate. If the tool
o p e r a t e s b u t t h e b r a k e d o e s n o t
consistently stop the accessory, DO NOT
use the grinder and have it serviced by a
Bosch Factory Service Center or Bosch
authorized service facility.
