model (refer to the “USE OF APPROPRIATE TOOLINGS”
table).
Ensure that the diameter of the middle collar

that keeps

the wires together is always greater than the diameter of
the fastening flanges

provided on the machine.

WARNING: It is prohibited to secure the brushes
with the flanges in direct contact with the wires.

Every now and then check the general condition of the
brush by visually inspecting it, especially as concerns the
hold of the wires, by means of the middle collar. If you
notice that the collar does not close perfectly any more,
replace the brush with a new one at once.

Fitting of the brush

WARNING: Prior to performing any maintenance
operation, disconnect the electric power supply.

Ensure that the machine is OFF and that the toolings
provided (e.g. grinding wheels) are perfectly still.
Use an Allen wrench to unscrew the screw nut

that locks

the flanges to the shaft.
Remove the tightening flange

from its seat.

Fit the brush onto the shaft , ensuring that the hole of the
brush has the same diameter of the shaft or of the adapting
bush provided onto which it is secured.
Re-position the tightening flange

onto the shaft making

it touch the collar

of the brush.

Remove the middle side plug

from the protection and

introduce a socket wrench through the hole until the seat is
properly fit on the shaft

At this point, keeping the shaft locked by means of the
socket wrench, tighten the fastening screw nut on the
flanges.
Try to turn the brush by hand to make sure that it is
centered. If it does not turn properly, repeat the aforesaid
steps.

USE OF THE SAND BELT

The right-hand side of the bench grinders/sanders (or right-
and left-hand sides of the sanders) houses a sand belt for
the grinding and sanding of various types of metals.
Belts with different sanding grains (40, 60, 80) are available
on request according to the type of required machining
(the lower the grain number, the greater the removal
capacity).
It is possible to use the sand belt both on the work table

and on the rubber-coated wheel

Use of the work table

In order to use the work table, adjust the opening of the
sliding guard

, raising it or lowering it so as to uncover

only the section required for passing the part to be
machined.
Ensure that the angle plate

is set not more than

2 mm.

from the belt’s surface and use it as a support for sustaining
the part.
The tilting of angle plate

can be adjusted for shaping the

parts as desired.

Use of the rubber-coated wheel

In order to use the rubber coated-wheel, fully shut the
sliding guard

and open the mobile guard

, unscrewing

the associated fastening screw.
Now the rubber coated-wheel may be used as if it were a
normal grinding wheel with the advantage that the part to
be machined can be oriented in any direction.

SAND BELT REPLACEMENT (Picture 11)

WARNING: Prior to performing any maintenance
operation, disconnect the electric power supply.

Make sure that the machine is OFF and that the toolings
present (grinding wheel, belt) are in standstill.
Unscrew the two handwheels

and open the side guard

Release the tensioning lever

and remove the sand belt

from the two wheels.
Position the new belt in the middle of the two wheels and re-
tension it by means of the lever

3.7

SAND BELT CENTERING (Picture 8-11)

Press the green pushbutton

of switch

by slight

impulses, ensuring that the belt remains perfectly positioned
in the middle of the two wheels.
In order to correct any side movements of the belt, turn
the centering handwheel slightly

, which is located at the

top of the belt unit, keeping in mind that when turning it
clockwise the belt moves sideways to the right.
