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 OPERATI-
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 (11).
If the chain sprocket (8) is worn, the clutch drum cpl. (12) must
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 (11) 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 A-H".
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).
