Maintenance and Service

Maintenance and Cleaning

Warning! Switch off, remove plug from
mains before adjusting, cleaning or if cable
is cut, damaged or entangled.
Note: To ensure long and reliable service, carry
out the following maintenance regularly.
Regulary check the chain saw for obvious de-
fects 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 mainte-
nance or repairs before using.

If the chain saw should fail despite the care tak-
en in manufacture and testing, repair should be
carried out by an authorised customer services
agent for Bosch power tools.
Note: Before returning the chain saw, ensure all
oil in the oil reservoir has been emptied. For
this, remove the sieve from the reservoir, empty
the reservoir and replace the sieve again.
In all correspondence and spare parts orders,
please always include the 10-digit article
number given on the type plate of the chain saw.
Replacing/Changing the Saw Chain and Chain
Bar (see figure A)
Check the saw chain and chain bar according to
section "Tensioning the Saw Chain".
The guide slot around the chain bar will wear
with time. When replacing the saw chain, turn
the chain bar by 180° to allow even wear. The
chain tensioning catch 22 must also be remount-
ed on the chain bar.
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.
