Operation
5 . Loosen the chain pitch wing-nut and move it to
the correct pitch position . Tighten it again .
Note: Adjusting the pitch is not the same thing
as adjusting the cutting tooth length (see section
5 .2 .7, “Set the cutter top plate to equal lengths”) .
6 . Set the chain pusher switch to ON . The chain
pusher arm now advances the chain forward .
7 . Visually make sure that the chain pusher stops
its movement exactly above the rivet behind the
cutting link, as illustrated in the image below .
8 . Set the chain pusher switch to OFF, when the
grinding head is in its uppermost position and
the chain lock is not engaged .
9 . Repeat steps 5-8 until the chain pusher stops in
the correct position .
CAUTION If the pitch is not correctly set,
the chain will be pushed into an incorrect
sharpening position . This may result in a
damaged chain .
5 .2 .6 Set the grinding depth
CAUTION If the metal of a cutting link turns
blue during grinding, the speed is set too high and
the metal is overheated . This can cause the metal
in the cutter to lose its properties . Avoid this by
grinding off less material during each turn, and - if
needed - do more turns .
1 . Fold the grinding head down to its grinding
position .
