9.2 Replacing the tools
Electric shock
Before replacing the tools, turn off the machine and ALWAYS disconnect the power plug from
the mains socket. This is so that there is no risk of electric shock.
Characteristics of the grinding wheels
Do not use grinding wheels with cavities.
Only use wheels with the size and characteristics indicated in the table of technical
specifications (see Section 3 of this manual)
The speed marked on the wheel must be equal to or greater than that specified in the
specifications table.
Characteristics of the Wheels
For the clamping of the grinding wheels only use flanges with identical size and shape
as the supporting surface.
The shims between the flanges and the grinding wheels must be made of elastic
materials such as rubber, soft cardboard etc.
If a caution label does not indicate the maximum permissible peripheral velocity or is
unreadable, calculate it using the following formula:
with
v: peripheral speed (in m/s);
n: rotation speed (in r/min);
D: external diameter of the wheel (in mm);
: 3.14.
Characteristics of the Wheels
DO NOT use grinding wheels with peripheral velocity lower than 30 m/s.
Characteristics of the Wheels
The hole of the grinding wheel should not be enlarged due to the possible danger of
breaking the grinding wheel.
Before fitting the wheel, check that there are no cracks and that it has not been
damaged during transport. We recommend that you tap it, a light sound confirms its
integrity.
