Maintenance and Cleaning

der to avoid a safety hazard.
Note: To ensure long and reliable service, carry out the follow-
ing maintenance regularly.
Regulary 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 us-

Replacing/Changing the Saw Chain and Chain Bar

the chain bar by 180° to allow even wear, thus extending
chain bar life.
Check the drive sprocket 20. If it is worn out or damaged due
to strain, have it exchanged by an authorized Bosch after-
sales service.
Sharpening the Saw Chain
Have your chain sharpened professionally at your authorised
Bosch after-sales service or sharpen it yourself with a sharp-
ening kit suitable for the chain recommended for your chain-
saw. Observe the sharpening instructions provided with the
sharpening kit.
Checking the Automatic Oiler
