25. SHARPENING WARNINGS
- Wear personal protection equipment when sharpening.
- All adjustments must be made with the motor switched off and the grinding
wheel completely stopped.
- In the case of accidental impact or collision of the wheel during the shar-
pening process, follow the instructions given in the "GRINDING WHEEL
WARNINGS" section.
- Clean the chain before sharpening it.
- To avoid overloading the motor excessively and to avoid damaging the chain cut-
ters , grind minimum quantities of material and do not stop along the same cutter
as this could burn the cutting edge.
- Sharpen all the cutters on the same side and then adjust the vise as explained in
the previous sections, then sharpen the cutters on the opposite side.
- Do not use cooling liquids during the sharpening process.
26. SHARPENING THE CHAIN
- Make sure the vise blocking handle M32 is screwed tight and the chain is blocked.
- Turn the machine on using switch I33 and sharpen the cutter by lowering the arm-
motor unit (fig.33).
- Once you have sharpened the chain, raise the arm and loosen the handle M32.
- Run the chain forward to position the next cutter to be sharpened.
- Block again with the handle M32 and sharpen.
28. GRINDING WHEEL DRESSING FOR SHARPENING THE DEPTH
GAUGE
- Fit the 6-mm thick grinding wheel (fig.37), following the instructions given in points
13-17-18-19.
- Turn the vise so that the "0" reference mark is on position 0 (fig.38).
- Turn the arm to take the "0" reference mark to 10°/15° (fig.38).
- Position the dressing brick on the jaws and against the chain blocking unit (fig.38).
Hold the dressing brick firmly with one hand (being careful not to touch the
grinding wheel).
- Profile the grinding wheel by activating the machine and grind the grinding wheel
until you obtain a profile like the one illustrated in fig.38.
- Switch the machine off once you have finished.
29. SHARPENING THE DEPTH GAUGE
- Remove the dressing brick and put the chain in the vise.
- Center the cutter compared to the grinding wheel by turning the knobs (P29 and
P30).
- Keeping the arm tilted, adjust the grinding depth on the gauge by turning knob P31
(fig.39).
- Sharpen the gauge following the instructions given in the "SHARPENING" section.
For this type of sharpening procedure, there is no difference between the right and
left cutters, therefore sharpen all the gauges one after the other.
- Check if the gauge depth is correct, using the template with the shape related to
the type of chain used (fig.40). Please also consult the chain table, column F.

30.4 HANDLING AND TRANSPORT
- If you need to transport the machine, take it off the bench or wall, dismantle the
grinding wheel and put all the parts in a packing box to protect them against impact.
30.5 DEMOLITION AND DISPOSAL
The machine is to be demolished by qualified personnel in compliance with current
laws in force in the country in which it is installed.
