Operation
5 .2 .7 Set the grinding depth
Use a low speed setting when you want to remove
a large amount of material, and a high speed
setting when you want to remove a small amount
of material .
1 .
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 .
2 .
Fold the grinding head down to its grinding
position .
3 .
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 .

5 .2 .8 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:
1 .
Do a sharpening test on a test chain, according
to the instructions in section 7 .2, "Sharpening
test" .
2 .
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 .
3 .
Repeat the sharpening test until the cutter top
plates are sharpened to equal lengths . See
section 3 .2, "Front view", position (N), and
adjust the grinding wheel according to the
pictogram under the chain vise .
5 .2 .9 Center the grinding disc
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 .
1 .
Use the grinding wheel centering knob to center
the grinding wheel over the chain . The gullets
should have equal depth on the left and right
cutting links .
2 .
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 .
3 .
Turn the grinding wheel centering knob to move
the grinding motor and the wheel up or down .
4 .
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 .
