9. SafeTy deVIceS
The grinder is equipped with the safety devices illustrated hereafter:
- grinding wheel guard:
it protects the operator from parts of the grinding wheel
that may come away during the sharpening process.
This guard must always be fitted in place when the machine is in use.
Always make sure the guard is efficient and fitted properly before you use the
machine. Operator’s safety could be compromised if the guard is damaged and/or
cracked.
- Switch:
the machine is equipped with a temporary operating switch: when it is
released, it automatically returns to the “open” position. This means that the machine
is always to be operated intentionally.
-
Thermal trip switch:
this device is built into the motor and, in the case of failure,
it cuts off the electric circuit and stops the machine. Operation is automatically
restored when the temperature of the trip switch is below 85°C.
10. InTended uSe
This machine is an electrical grinder for chains used in chain saws.
- Use the machine exclusively for the types of chains stated in the technical data
chart.
- Do not use the machine to cut or grind anything other than the chains envisaged.
-- The machine must not be used in corrosive or explosive environments.
- any other use is to be considered improper.
The manufacturer is not liable for damages following improper or incorrect use of
the machine.

13. InSTallaTIon
aTTenTIon
Do not install the machine at eye level. You are recommended to install it at a height
of no more than 1.2-1.3 meters off the floor.
The machine can be bench mounted or wall mounted.
13.1 BencH mounTIng (fIg. 4)
- Securing the base unit (fig.4): use 2 M8 screws complete with washers and nuts
(material not supplied), inserted in the securing holes F4. Make sure you position
the base unit on the bench as illustrated in the detail so that the reference notches
at the bottom touch the edge of the bench.
13.2 Wall mounTIng (fIg. 5)
- Use the special bracket, code 1185049 (not supplied) to wall-mount the grinder.
- Secure the bracket using two dowels with relative screws complete with washers
(material not supplied), inserted in the securing holes.
- Secure the machine using 2 M8 screws complete with washers and nuts (material
not supplied), inserted in the securing holes F4.

15. cHaIn IdenTIfIcaTIon
- Before you start to sharpen, you need to know the type of chain and the relative
adjustment angles. These characteristics are written in the owner’s manual of the
chain saw on which the chain is fitted or on the chain pack.
- The chain identification code is usually written on the driving link.
- You can also identify the chain using a template and a gauge.
- At the end of this manual you will find the CHAIN CHART.
The columns in this chart provide the following information:

15.1 InSTrumenTal meaSuremenTS (fIg.8)
a - Measure the gauge depth using the suitable shape.
b - Put the template on this side and measure the chain PITCH.
c - Put the template on this side to measure the cutter length.
d - The driving link width can be measured using a suitable instrument (e.g. gauge).
16. fITTIng THe grIndIng WHeel
16.1 cHecKIng THe grIndIng WHeel (fIg. 3)
Hold the wheel up by its central hole. Knock the edge of the grinding wheel delicately
using a metal object
(fig. 3)
. If it makes a non-metallic and numb sound, it means
that the grinding wheel could be damaged.
do not use it!
16.2 grIndIng WHeel WarnIngS
- Use a grinding wheel suitable for the type of chain to be sharpened; consult the
chain chart at the end of the manual.
- Do not force the grinding wheel on the hub and do not alter the centering hole
diameter. Do not use grinding wheels that do not fit perfectly in place.
- Use exclusively clean and perfect intact hub and flange to fit the grinding
wheel.
- Make sure the outside diameters of the hub and flange are identical (fig.9).
16.3 SecurIng THe grIndIng WHeel
- Loosen and remove the ring nut G10
(fig. 10)
- Insert and perfectly centre the grinding wheel in the dedicated seat on the hub
(fig.11)
.
- Screw the ring nut G910, as indicated in
fig.9-12
.
make sure you fit the flange as illustrated in fig.9.
If the grinding wheel is fitted with the flanges too tight, it could break during
use and put the operator at risk.
17. SecurIng THe grIndIng WHeel guard
- Put the guard P13 on the arm (fig. 13)
- Make sure the tab L13 is inserted correctly in the seat S13 of the guard P13
(fig. 13)
- Make sure the two hooking teeth D14 are hooked correctly on the edge of the arm
(fig. 14)
- Insert and tighten the screw V13 in its seat to secure the guard P13 (fig. 14)
do not tighten the securing screw excessively to avoid cracking the
guard
18. elecTrIcal connecTIon
- Make sure the electrical system power supply complies with the values written on
the rating nameplate.
- The power supply voltage must not differ from that written on the nameplate by
±5%.
- The connection to the electric mains must be prepared subject to current standards
in force in the country in which the machine is used.
- The power socket used for the machine must have an earth wire, adequate fuse
and must be protected by a differential circuit breaker with tripping sensitivity no
higher than 30 mA.
19. STarT-uP
- Plug the power cable into the mains.
