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 thrust washer (
11
).
If the sprocket (
8
) is worn out, the complete clutch drum (
12
)
will need to be replaced (for the part number, see “Extract from
the spare parts list”).
Install a complete new clutch drum (
12
), cup washer (
11
) and
new 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:
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”).
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 complete clutch drum (12) must be changed to fit the different chain. If neces
-
sary, replace it.
