Maintenance and Cleaning
Warning: Switch off and remove battery from power
tool before adjusting or cleaning.
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.
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
using.
Note: Before returning the chain saw, ensure all oil in the oil
reservoir has been emptied.
Replacing/Changing the Saw Chain and Chain Bar
(see figures B1–B4)
Check the saw chain and chain bar according to section
"Tensioning the Saw Chain".
Exchange a worn chain bar.
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
Do not sharpen the saw chain yourself, unless you are
experienced in doing so. Please obtain the replacement saw
chain (F 016 800 489) or have your chain sharpened
professionally at your authorized Bosch after-sales service.
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
ground. Do not touch the ground with the chain and ensure a
safety clearance of 20 cm. If an increasing oil pattern
develops, the automatic oiler is operating fine. If there is no oil
pattern despite a full oil reservoir, see section
"Troubleshooting" or contact your authorized Bosch after-
sales service.
After Use/Storage
Remove the oil from the reservoir before storage.
Clean the moulded plastic housing of the chain saw using a
soft brush and clean cloth. Do not use water, solvents or
polishes. Remove all debris, especially from the motor
cooling vents.
After 1 – 3 hours of use, remove the cover 15, the chain bar
11 and the saw chain 12, and clean them using a brush.
