Cutter
21.3 SETTING THE TOP SHARPENING
ANGLE (FIG. 14-16)
- Loosen the knob M16.
- Turn the vise counter clockwise.
- Position the reference notch on the vise
by the desired angle.
- Tighten knob M16 again.
21.4 SETTING THE CHAIN BLOCKING UNIT (FIG. 17)
- Put the chain in the vise.
- Take the cutter up against the chain blocking device A18.
- Run the pin P18 in its seat to position the blocking unit A18
correctly compared to the cutter.
21.5 POSITIONING THE CUTTER (FIG. 17)
- Move the grinding wheel onto the cutter to be sharpened
by pulling the arm downwards.
- Turn the knob P18a to move the chain so that the cutter
cutting edge skims the grinding wheel. The chain should
run freely over the vise throughout this procedure but
without any play.
- At this stage, raise the arm and screw the knob P18a, to
move the cutter to be sharpened further forwards.
This forward movement corresponds to the quantity of
material to be ground from the cutter.
Blunter are the cutters, greater must be this forward
movement. Vice versa, for cutters that are not too blunt,
simply grind just a slight amount of material.
- Turn knob P18b to adjust the cutter sharpening depth.
The grinding wheel should skim the bottom of the cutter
vertically.
- Once you have found the exact position of the cutter,
tighten the chain blocking handle M19.
22. 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 sharpening process, follow
the instructions given in the “GRINDING WHEEL
WARNINGS” section.
- It is recommended to clean the chain before sharpening it.
- To avoid overloading the motor excessively and to avoid
damaging the chain cutters, 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.
23. SHARPENING THE CHAIN (FIG. 18)
- Make sure the vise blocking handle M19 is screwed tight
and the chain is blocked.
- Turn the machine on using the operating switch I19 and
hold it down then sharpen the cutter by lowering the arm-
motor unit.
- Once you have sharpened the chain, raise the arm, release
the switch and loosen the handle M19.
- Run the chain forward to position the next cutter to be
sharpened.
- Block again with the handle M19 and sharpen.
24. SHARPENING THE DEPTH GAUGE (FIG. 19)
- The depth of the depth gauge normally needs restoring
after the cutter has been sharpened 2 or 3 times. To do
this, grind material from the depth gauge itself using an
appropriate flat file (not supplied with the machine).
- Check if the gauge depth is correct, using the template
with the shape related to the type of chain used. Please
also consult the chain table, (column F).

25.4 HANDLING AND TRANSPORT
- If you need to transport the machine, take it off, dismantle
the grinding wheel and put all the parts in a packing box
to protect them against impact.
- Take and lift the package with care, as indicated in (fig. 20) .
25.5 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.
The symbol (on the rating nameplate) points out that
the product must not be disposed of with normal household
garbage. Contact an authorized service centre or your dealer
for disposal instructions.
Before you scrap the machine, make it unusable
(by cutting the power supply cable for example) and
make the parts safe, which could cause a source
of danger for children if they should play with the
machine.
