5 . Change the grinding setting for the height of the
depth gauges .
• Do a sharpening test on a test chain,
according to the instructions in section 7 .2,
"Sharpening test" .
• Use the set depth gauge to adjust the position
of the machine to set up the remaining depth
gauges . Turn the depth gauge height knob
– clockwise to increase the height of the
depth gauge (and therefore grind less of it),
or
– counter clockwise to decrease the height
of the depth gauge (and therefore grind
more of it) .
• Repeat the sharpening test until the height of
the depth gauges is correct . Use the template
provided with the machine and refer to the
top-plate angle chart to determine the correct
height .
6 . Adjust the feed so that the grinding wheel
touches the depth gauge .
7 . Make the grinding settings according to the
manufacturer's recommendations .
