Check the sprocket before mounting a new chain.
Worn out sprockets (8) may damage the new chain and must
therefore be replaced.
Remove the sprocket guard (See „PUTTING INTO OPERA-
TION“).
Remove the chain and guide bar.
Remove circlip (9).
CAUTION: The circlip will pop out of the groove. When removing
it, hold your thumb against it to prevent it from popping off.
Remove washer (10).
Replace the old sprocket (8) with a new one (11). For the part
number consult the “Extract from the spare parts list”.
Install a new chain sprocket, washer and circlip (9) (for the part
numbers see “Extract from the spare parts list”).
For replacing the guide bar, chain, and sprocket see „PUTTING
INTO OPERATION“.
NOTE:
Do not use a new chain with a worn chain sprocket. Replace
the chain sprocket after no more than two worn out chains. Let
the new chain run at half-speed for a few minutes to distribute
the chain oil evenly.
New chains stretch, so check the chain tension frequently (see
“Checking the chain tension”).
Change the clutch drum after two worn out chain sprockets.
Replacing the saw chain
CAUTION: Use only chains and guide bars designed for this saw (see the Extract from the spare-parts list)!
When changing the type of chain, the chain sprocket (11) will need to be modified for the chain type. It may be neces-
sary to replace the chain sprocket.
