20. cHecKIng THe grIndIng WHeel aSSemBly
Wear personal protection equipment when carrying out these jobs.
When checking the assembly of the grinding wheel, make sure no other
person stands near the machine.
- Start the machine by holding the operating switch down for 1-2 seconds and make
sure the grinding wheel does not move sideways or crosswise during the slowdown
phase, which could cause abnormal vibrations. If this occurs, do not start the
machine again but make sure the grinding wheel has been assembled correctly. If
necessary, replace the grinding wheel with another original one.
- Operate the machine again holding the operating switch down for 30 seconds.
Stand at the side of the rotation surface of the grinding wheel and visually make
sure the grinding wheel does not move sideways or crosswise, which could cause
abnormal vibrations. If this occurs, stop the machine immediately and make sure
the grinding wheel has been assembled correctly. If necessary, replace the grinding
wheel with another original one.
Each time a grinding wheel is fitted, follow the instructions given in the section
entitled FITTING THE GRINDING WHEEL

21.1 SHarPenIng angleS
- Once you have established the type of chain to be sharpened, look-up the vise
adjustment angle in the chain chart (column C).

- Loosen the knob M16.
- Turn the vise clockwise.
- Position the reference notch on the vise by the desired angle.
- Tighten knob M16 again.

21.3 SeTTIng THe ToP SHarPenIng angle (fIg.16-18)
Cutter
- 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.18)
- 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. 18)
- 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 shar-
pening 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 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.
23. SHarPenIng THe cHaIn (fIg. 19)
- 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. 20)
- 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. SToPPIng and SHuTTIng doWn
25.1 SToPPIng
Unplug the power cable from the mains.

25.2 SHuTTIng doWn

Once you have finished using the machine, disconnect it and clean it thoroughly.
Store it in a dry and safe place, protected against dust and damp.
25.3 rouTIne maInTenance
Follow the instructions given in the "STOPPING" section before you start to
work on the machine.
maintenance interval
When the grinding wheel reaches a
minimum diameter of approximately 85
mm (3.34 in)
40 hours

25.4 HandlIng and TranSPorT

- If you need to transport the machine, take it off the bench or wall, dismantle the grind-
ing wheel and put all the parts in a packing box to protect them against impact.
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.
