Troubleshooting

The following chart lists problem symptoms, possible causes and corrective action, if your machine does not operate properly. 
If these do not identify and correct the problem, contact your service agent.



Warning: Switch off and remove plug from mains before investigating fault.

Maintenance and Cleaning



Before any work on the machine itself, pull the mains 
plug.

If the replacement of the supply cord is necessary, this has to 
be done by Bosch or an authorized Bosch service agent in or-
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-
ing.

Note: 

Before returning the chain saw, ensure all oil in the oil 

reservoir has been emptied.

Replacing/Changing the Saw Chain and Chain Bar

Check the saw chain and chain bar according to section “Ten-
sioning the Saw Chain”.

The circular groove of the chain bar will wear particularly on 
the lower edge with time. When replacing the saw chain, turn 
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

Proper functioning of the automatic saw chain oiler can be 
checked by running the chain saw and pointing the tip of the 
chain bar towards a piece of cardboard or paper on the
