Maintenance and Service
Maintenance and Cleaning
Before any work on the garden product itself (e. g. maintenance, tool change, etc.) as well as during transport and
storage, remove the battery from the garden product. There is danger of injury when unintentionally actuating the
On/Off switch.
Note: To ensure long and reliable service, carry out the following maintenance regularly.
For safe and proper working, always keep the power tool and its ventilation slots clean. Regularly check the chain
saw for obvious defects such as loose, dislodged or damaged saw chain and chain bar, loose fixings and worn or
damaged components.
Check that covers and guards are undamaged and correctly fitted. Carry out necessary maintenance or repairs
before using.
Regularly check the chain saw for obvious defects such as loose, dislodged or damaged saw chain and chain bar,
loose fixings and worn or damaged components.

is refilled before using the chain saw again.
Replacing/changing the saw chain and chain bar (see figures A1–A4)
Use only original Bosch accessories.
