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 char-
acteristics 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 driv-
ing 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:

A Chain pitch
B Driving link width
C Top sharpening angle (vise rotation)

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 dedi-
cated seat on the hub (fig.11).
- Screw the ring nut G10, 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).
