01 SPROCKET GUARD / CHAIN TENSIONING SYSTEM
How the chain tensioner works
The force applied to the adjusting screw is transferred
by the angle worm drive to the tensioning pin.
Replace the chain guide 1 if it is worn.
Mount the housing 2 in the sprocket guard with
slotted screw 3 (3.5 x 9.5).
NOTE: The worm drive is available only as a set 5.
Grease the spindle and worm with multipurpose
grease (944.360.000).
Chip guide
The chip guide ensures that chips are deflected away
from the cut.
This is especially important for rip cuts, to prevent
clogging.
To replace it, push the catch 4 inwards from the
outside of the chain guard.
