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 .
