Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Store the battery only within a temperature range between
0 °C and 50 °C. As an example, do not leave the battery in the
car in summer.
Occasionally clean the venting slots of the battery using a soft,
clean and dry brush.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Observe the notes for disposal.
Maintenance and Service
Maintenance and Cleaning
 Before any work on the machine (e. g., maintenance,
tool change, etc.) as well as during transport and stor-
age, set the rotational direction switch to the centre
position. Unintentional actuation of the On/Off switch can
lead to injuries.
 For safe and proper working, always keep the machine
and ventilation slots clean.
Replacing the Carbon Brushes (see figure D)
Check the length of the carbon brushes approx. every
2 –3 months and replace the carbon brushes if required.
Never replace only a single carbon brush!
Note: Use only carbon brushes supplied by Bosch and intend-
ed specifically for your product.
– Unscrew the caps 16 using a suitable screwdriver.
– Replace the spring-loaded carbon brushes 15 and screw
the caps back on again.
