ON" figs.
B
).
Remove the chain and guide bar.
Remove circlip (
9
).
CAUTION:
The circlip will pop out of the groove. When remov-
ing it, hold your thumb against it to prevent it from popping off.
Remove thrust washer (

If the chain sprocket (
8

be replaced. For the part number consult the “Extract from the
spare parts list”.
Put on the washer disc (
13
), new clutch drum cpl. (
12
), cup
washer (

) and new circlip (
9
) montieren (for the order number
see “Extract from the spare parts list”).
For replacing the guide bar, chain, and sprocket see "PUTTING
INTO OPERATION

".
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
replacement. 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”).
Instructions for changing the chain type
Always wear protective gloves!
-
Before using a
3/8"
saw chain, be sure to first cut out the
marked section of the chip deflector (
14
)!
-
To do this, first cut along the marking (
15
) with a sharp
knife and then cut across to remove the piece.
NOTE:
If switching to chain type .325" it will be necessary to install a
newchip deflector (see „Extract from the spare parts list“ for the
part number).
