model (refer to the "USE OF APPROPRIATE TOOLINGS"
table).
Ensure that the diameter of the middle collar 18 that keeps
the wires together is always greater than the diameter of
the fastening flanges 19 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 20 that locks
the flanges to the shaft.
Remove the tightening flange 19 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 19 onto the shaft making
it touch the collar 18 of the brush.
Remove the middle side plug 21 from the protection and
introduce a socket wrench through the hole until the seat is
properly fit on the shaft 22.
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.
3.5 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 23
and on the rubber-coated wheel 24.
Use of the work table
In order to use the work table, adjust the opening of the
sliding guard 25, 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 26 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 26 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 25 and open the mobile guard 27, 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.
3.6 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 28 and open the side guard
29.
Release the tensioning lever 30 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 30.
3.7 SAND BELT CENTERING (Picture 8-11)
Press the green pushbutton 14 of switch 2 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 31, 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.
