Replacing the saw chain
CAUTION: Use only chains and guide bars designed for 
this saw (see the Extract from the spare-parts list)!
Check the sprocket before mounting a new chain.
Worn out sprockets (12) may damage the new chain and must 
therefore be replaced.
Remove the sprocket guard (1) (See "PUTTING INTO OPE-
RATION" figs. B).
Remove the chain and guide bar.
Remove circlip (13).
CAREFUL: The circlip will jump out of the groove unless you 
hold it down with your thumb while removing it.
Remove thrust washer (15).
Replace the old sprocket (12) with a new one (16). For the part 
number consult the “Extract from the spare parts list”.
Assemble the new sprocket, thrust washer and circlip.
For replacing the guide bar, chain, and sprocket see "PUTTING 
INTO OPERATION A-H".
NOTE:
New chains stretch, so check the chain tension frequently (see 
“Checking the chain tension”).

Replacing the fuel filter
The  felt  filter (17) can become clogged. It is recommended to 
replace the fuel filter once every three months in order to ensure 
unimpeded fuel flow to the carburetor.
To remove the fuel filter for replacement, pull it out through  
the tank filler neck using a piece of wire. Bent wire at one end 
to form a hook.

Cleaning the guide bar
CAUTION: Protective gloves must be worn.
Regularly  inspect  the  bearing  surfaces  of  the  guide  bar  for 
damage, and clean them with a suitable tool.
