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:
÷ 2
A Chain pitch
B Driving link width
C
Top sharpening angle (vise rotation)
F Gauge depth
G Grinding wheel thickness
H Grinding wheel code
I Oregon chain codes
L Windsor chain codes
M SABRE/TSC/EXCEL chain codes
N Carlton chain codes
O Stihl chain codes
P EM chain codes

15.1 INSTRUMENTAL MEASUREMENTS (FIG. 6)
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. 7)
Hold the grinding wheel up by its central hole. Knock the
edge of the grinding wheel (fig. 7) 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!
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. 8).
16.3 SECURING THE GRINDING WHEEL
- Insert and perfectly centre the grinding wheel in the
dedicated seat on the hub (fig. 9).
- Insert and perfectly centre the washer R11 on the hub.
- Screw the ring nut G10, as indicated in fig. 8-9-10.
Make sure you fit the flange as illustrated in fig. 8.
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. 11).
- Make sure the tab L13 is inserted correctly in the seat S13
of the guard P13 (fig. 11).
- Make sure the two hooking teeth D14 are hooked correctly
on the edge of the arm (fig. 12).
- Insert and tighten the screw V13 in its seat to secure the
guard P13 (fig. 12).
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.
