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 machine 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 machine features a safety switch with release coil. In the case of a
sudden power failure, the switch trips automatically and disconnects the machine
from the mains. The machine will not start even if the power supply is suddenly
restored. You need to reset the switch to start the machine again.
- Lock pin: this is used to block the arm in the completely raised position.
When the pin is loosened, the arm is blocked. This condition is required when
adjusting the sharpening angles, when replacing and dressing the grinding wheel.
When the pin is tightened, the arm is free to move. This condition is required during
the sharpening process.
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.
- Secure the machine firmly to the bench or wall.
- 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. 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 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.
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.
(fig.11) Cutter parts:
1 Top part
2 Top cutting angle
3 Side cutting angle
4 Sharpening recess
5 Depth gauge
6 Bit
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)
E Down angle (vise inclination)
F
Gauge depth
G Grinding wheel thickness
H Grinding wheel code
I Oregon chain codes
L Windsor chain codes
M SARP chain codes
16.1 INSTRUMENTAL MEASUREMENTS (FIG.13)
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).
