Operation
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.
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.
Grinding wheel diameter:
150mm (5.9")
(new grinding wheels)
140mm (5.5")
130mm (5.1")
• Repeat steps 1-2 until the grinding depth is
equal.
15. To set the approximate grinding length, turn the
chain pusher adjustment knob:
• clockwise, to grind more, resulting in a shorter
cutter top plate, or

• counter-clockwise, to grind less, resulting in a
longer cutter top plate..
16. Set the chain pusher switch to ON. The chain
pusher arm will push the chain forward
Scale:
17. Monitor the grinding wheel movements, and
1-3
check if the chain is sharpened.
18. If required: Turn the grinding depth knob,
3-5
located on the back of the grinding head, to
4-6
make minor adjustments for the grinding depth.
19. If required: Turn the chain pusher adjustment to
make minor adjustments for the grinding length.
