9. SAFETY DEVICES
The grinder is equipped with the safety devices illustrated hereafter:
- Shield guards: they protect the operator from parts of the grinding wheel that may
come away during the sharpening process.
These guards must always be fitted in place when the appliance is in use.
Always make sure the guards are efficient and fitted properly. Operator safety could
be compromised if the guards are damaged and/or cracked.
- Switch: the appliance features a safety switch with release coil. In the case of a
sudden power failure, the switch trips automatically and disconnects the appliance
from the mains. The appliance will not start even if the power supply is suddenly
restored. You need to reset the switch to start the appliance again.
10. INTENDED USE
This appliance is an electrical grinder for chains used in chain saws.
- Use the appliance exclusively for the types of chains stated in the technical data
chart.
- Do not use the appliance to cut or grind anything other than the chains envisaged.
- Secure the appliance firmly to the bench or wall.
- The appliance must not be used in corrosive or explosive environments.

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 non-metallic 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 appliance 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 appliance can be bench mounted or wall mounted.

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
Driving link width
C
Top sharpening angle (vise rotation)
D
Cutting angle (arm rotation)
E
Down angle (vise inclination)
F
Gauge depth
G
Grinding wheel thickness
H

16.1 INSTRUMENTAL MEASUREMENTS (FIG.9)
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 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. 10)
- Remove the screw V8 and the flange F8 on the hub (fig.11)
- 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.12-13).
- Insert the flange F8 and tighten the screw V8 (fig.12).
Make sure you fit the flange as illustrated in fig.13.
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 7 Nm (if possible, check with dynamometric spanner).
- Close the guard again P10 and tighten the relative screw V10 (fig.14).
18.1 REPLACING THE CHAIN STOP KIT (FOR 3/4" CHAINS)
- The special chain stop kit must be fitted for 3/4" chains only.
- Loosen and unscrew the knob P14 (fig. 14A).
- Remove the chain stop kit K1 (fig. 14B).
- Fit the 3/4" chain stop kit K2 (fig. 14C and 14D).
- Screw up and tighten the knob P15 (fig. 14E).
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 appliance immediately and check if the grinding
wheel has been fitted correctly. If necessary, replace the grinding wheel with another
original one.
