Þ
gs.

).
Remove the chain and guide bar.
Remove circlip (

CAUTION:
The circlip will pop out of the groove. When removing
it, hold your thumb against it to prevent it from popping off.
Remove thrust washer (

see “Extract from the spare parts list”).
For replacing the guide bar, chain, and sprocket see „PUTTING

NOTE:
Don’t use a new chain on a worn chain sprocket. By the time
2 chains have worn, the sprocket has become worn out, so
it should be replaced at least at every second chain replace-
ment. To distribute the chain oil evenly, run a new chain at
half-throttle for a few minutes before use.
New chains stretch, so check the chain tension frequently (see
“Checking the chain tension”).
