13. TESTING THE GRINDING WHEEL
Hold the grinding wheel up by its central hole. Knock the edge of the grinding wheel
(fig.3) gently with a metal object. If it makes a numb non-metallic noise it means that
the wheel could be damaged: do NOT use it!
14. INSTALLATION
ATTENTION
Do not install the machine at eye level. You are recommended to install it at a height
of no more than 3.9 to 4.2 feet (1.2-1.3 m) from the floor.
The machine can be bench mounted or wall mounted.

14.1 BENCH MOUNTING

- 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.
- Fitting the arm (fig.5): to secure the arm-motor unit to the base unit, insert the V5 screw
in the dedicated hole F5. Insert the R5 washer at the back and tighten the knob M5.

14.2 WALL MOUNTING

- Securing the base unit (fig.6): use two dowels with relative screws complete with
washers (material not supplied), inserted in the securing holes F6.
- Fitting the arm (fig.5): to secure the arm-motor unit to the base unit, insert the V5
screw in the dedicated hole F5. Insert the R5 washer at the back and tighten the
nut D5.
14.3 SECURING THE OPERATING HANDLE (FIG.7)
- Insert the screw V7 in the relative hole in the arm and secure it with the nut D7.
- Completely screw the operating handle I7 on the screw V7.
14.4 SECURING THE SHIELD GUARDS
Do not screw the screws too tight during this job to avoid cracking the
guards.
- Remove the screw V8 and the flange F8 on the hub (fig.8).
- Secure the guard P9, by screwing the screw V9, complete with washer R9, in the
relative hole F9 (fig.9).
- Secure the arbor shield P10, by screwing the screw V10, complete with washer
R10, in the relative securing hole F10 (fig.10).
15. CHAIN INFORMATION
The chain must be completely inspected before sharpening it to make sure it is
intact.

1 Top plate
2 Top cutting angle
3 Side cutting angle
4 Gullet
5 Depth gauge
6 Toe
7 Heel
8 Rivet hole
16. 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 or gauge.
- Consult the CHAIN CHART at the end of this manual.
The columns in this chart provide the following information:
÷ 2
A Chain pitch
B Gauge
C Top sharpening angle (vise rotation)
D Cutting angle (arm rotation)
F Depth gauge
G Grinding wheel thickness
H Grinding wheel code

16.1 INSTRUMENTAL MEASUREMENTS (FIG.13)
a - Measure the depth gauge 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 is measured using a suitable instrument (i.e. gauge).
17. 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.
18. FITTING THE GRINDING WHEEL
- Loosen the screw V10 and turn the guard P10 (fig.14).
- Choose the grinding wheel based on the type of chain to be sharpened (column H
in chain chart).
- Insert and perfectly center the grinding wheel in the dedicated seat on the hub
(fig.14-15).
- Insert the flange F8 and tighten the screw V8 (fig.14).
Make sure you fit the flange as illustrated in fig.15-16.
If the grinding wheel is fitted with the flanges too tight, it could break during
use and put the operator at risk. To avoid such risk, tighten screw M6x25 to
62 in-lbs (7 Nm). If possible, check with dynamometric spanner.
- Close the guard again P10 and tighten the relative screw V10.
19. CHECkING THE ASSEMBLY OF THE GRINDING WHEEL
- Stand at the side of the grinding wheel, start the grinder and visually make sure
the grinding wheel does not oscillate sideways or crosswise, consequently causing
abnormal vibrations.
- If this should be the case, stop the machine immediately and check if the grinding
wheel has been fitted correctly. If necessary, replace the grinding wheel with another
original one.
Always check a freshly fitted grinding wheel at working speed for at least one
minute before you start grinding, standing at a safe distance and making sure
nobody else approaches the machine.

20. 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.
21. START-UP
- Plug the power cable into the mains.
22. CHECkING THE GRINDING WHEEL SHAPE
- With the machine turned off, check the grinding wheel profile using the dedicated
template (fig.17); if necessary, dress the wheel to restore the correct profile.
23. GRINDING WHEEL DRESSING
Wear personal protection equipment.
- Start the grinder by turning the switch to position "1".
- Profile the grinding wheel with the dressing brick, always working with extreme
caution, holding it with two hands firmly and effectively (fig.18).
- Stop the machine and check if the profile is correct using the template (fig.19).
Contact with the grinding wheel while it spins at high speed may cause
burning and abrasions.
24. ADJUSTING THE VISE
NB. Before sharpening, the chain MUST be positioned in the exact centre of the
two jaws fixed on the vise (always with the motor switched off).
- Establish the type of chain to be sharpened, by identifying the thickness of the drive
link (column B "gauge" of the chain chart).
- Get hold of a new section of chain with at least two cutters opposed with the
same gauge as the chain to be sharpened. Position it on the vise with the depth
gauge facing the right (fig. 20).
- Look-up the adjustment angles (vise and arm) in the chain chart (columns A/C),
related to the new section of chain.
- Turn screw V20a to position the chain in the rotational centre of the vise (fig. 20a). This
condition is fundamental to obtain the same length of the right and left cutters.
