Operation
10. Turn the grinding speed knob to set the desired
speed for the machine.
IMPORTANT If the metal of a cutter 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 re-sharpen the chain.
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 8.2,
“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 increase the length of the right
cutter and decrease the length of the left
cutter, or
– counter clockwise to decrease the length of
the right cutter and increase the length of the
left cutter.
• Repeat the sharpening test until the cutter top
plates are sharpened to equal lengths.
14. The diameter of the grinding wheel decreases
when it is used. To maintain the grinding
proportions, the grinding wheel position must
be changed when:
• the grinding wheel has been worn, or
• the chain has a different pitch that requires a
different wheel. The grinding wheel centering
knob is used to center the grinding wheel
over the chain. The gullets should have equal
depth on the left and right cutting links.
– Sharpen a few links and then visually
inspect the result. If the grinding depth is
not equal on the gullets of the right and left
cutting links, continue to the next step.
– Turn the grinding wheel centering knob to
move the grinding motor and the wheel up
or down. Set the arrow on the scale to
point to the number that corresponds to the
wheel diameter, as displayed below. These
scale numbers are approximate and are
only for general guidance. Observe if the
grinding depth of right and left gullets are
equal for final adjustment.
