Maintenance and Service
6 .3 Change the grinding wheel and
fit the grinding wheel guard
WARNING Before a chain is sharpened, make
sure that the grinding wheel is not cracked, does not
vibrate or wobble . There is a simple test (called the
“ring test”) that you can do to check for damage (see
section 4 .7, “Install and center the grinding wheel”) .
IF THE GRINDING WHEEL IS DAMAGED IT MUST
BE REPLACED IMMEDIATELY .
If abnormal vibrations occur during operation, stop
the machine immediately and check the condition of
the grinding wheel .
The machine comes with 2 grinding wheels of
different sizes . To order more grinding wheels, see
8, “Accessories and Spare Parts” .
1 . Press the stop button to turn the power off .
2 . Lift the grinding head to its most upright
position .
3 . If the grinding wheel guard is already attached:
Loosen the 2 attachment knobs (D) and remove
the guard (C) .

wheel axis .
7 . Tighten the nut (B) by hand to secure the
grinding wheel in its position . Do not over-

position and fasten the 2 knobs (D) .

instructions in 5 .2 .9, “Center the grinding disc” .
6 .4 Set the depth gauge height
1 . Do a sharpening test on a test chain, according
to the instructions in section 7 .2, “Sharpening
2 . Verify the correct depth gauge setting (refer to
the illustration) .
3 . Turn the grinding depth knob to set the depth
gauge: See section 3 .2, “Front view” position
(H) .
• 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) .
4 . Repeat the sharpening test until the height of
the depth gauges is correct .
6 .5 Fasten the chain lock
The chain lock needs to be fastened if the chain is
not fixed during sharpening .
1 . Insert a 1,8–2,0 feeler gauge into the groove of
the chain lock to measure the groove width .
1.8-2.0 mm
