N Flip the guide bar – each time the
chain is changed – to avoid uneven
wear, especially at the sprocket
nose and on the bottom
N Periodically clean the water inlet
hole (1), water outlet channel (2)
and bar groove (3)
N Measure groove depth – using the
measuring tool on the file gauge
(special accessory) – in the area
with the greatest wear
If the groove is not at least 6 mm deep:
N Replace guide bar
Otherwise the drive links will grind
against the base of the groove – tie
straps will not lie against the bar.
If the guide bar runs in the cut:
N Check guide bar for uneven wear
(ridge offset)
N Flip the guide bar, if necessary
remove the bore of the guide bar
with guide bar straightener
N Remove chain sprocket cover,
diamond abrasive chain and guide
bar
Replacing rim sprocket
– If the diamond abrasive chain is
being replaced, also replace the rim
sprocket
– If the wear marks (arrows) are
deeper than 0.5 mm – otherwise the
service life of the diamond abrasive
chain is reduced – use check gauge
(special accessory) to test
Using two diamond abrasive chains in
alternation helps preserve the chain
sprocket.
Removing rim sprocket
If only the rim sprocket is removed, the
clutch drum does not need to be
removed.
