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.
When disassembling the saw chain, take care that the chain is
first loosened with the chain tensioning ring 13. Disassembly
of the chain saw without first loosening the saw chain can
damage the chain saw.
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.
Reverse the chain tensioning catch 22 by removing the
screws and refitting it on the opposited side.
Check the drive sprocket 18. 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
ground. Do not touch the ground with the chain and ensure a
safety clearance of 20 cm. If an increasing oil pattern devel-
opes, the automatic oiler is operating fine. If there is no oil
pattern despite a full oil reservoir, see section "Troubleshoot-
ing" or contact your authorized Bosch after-sales service.
After Use/Storage
Clean the moulded plastic housing of the chain saw using a
soft brush and clean cloth. Do not use water, solvents or pol-
ishes. 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 10, and clean them using a brush.
Clean the area under the cover 15, the drive sprocket 18 and
the chain bar assembly from adherant debris using a brush.
Clean the oil outlet 19 with a clean cloth.
If the chain tensioning mechanism in the cover 15 becomes
difficult to operate, remove the protective lid , turn the lock-
ing knob 14 and the chain-tensioning ring 13 against each
other, so that debris is loosened from the mechanism and can
be discarded. Carefully strike or tap out debris from the cover
15. If the mechanism is heavily clogged, use a soft brush or
compressed air for cleaning. Do not use tools of any kind.
If the chain saw is to be stored for a longer period of time,
clean the saw chain 10 and the chain bar 11.
Store the chain saw in a secure, dry place, out of the reach of
children.
Do not place other objects on the chain saw.
Please take care to place down the chain saw with the oil filler
cap 4 facing upward.
When storing in the sales packaging, the oil reservoir must be
completely emptied.
