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.
10. Turn the grinding speed knob to set the desired
speed for the machine.
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. Replace
the damaged cutter or sharpen the chain again.
11. Fold the grinding head down to its grinding
position.
12. The grinding depth for gullets is recommended
by the chain manufacturer. To set it, turn the
grinding depth knob, located on the back of the
grinding head:
• clockwise, to grind shallower into the gullet, or
• counter-clockwise, to grind deeper into the
gullet.
13. Set the cutter top plate to equal lengths. If the
right (outer) and left (inner) cutters are not
sharpened to equal lengths, follow these steps:
• Do a sharpening test on a test chain,
according to the instructions in section 7.2,
"Sharpening test".
• Make sure that the right and left cutting
teeth are sharpened to equal lengths. Use
the template provided with the machine to
measure. If they are not equally long, turn the
equal cutting teeth knob:
– clockwise to decrease the length of the left
cutter and increase the length of the right
cutter, or
– counter clockwise to increase the length of
the left cutter and decrease the length of the
right cutter.
• Repeat the sharpening test until the cutter top
plates are sharpened to equal lengths.
