7. Maintenance
BEFORE ANY INTERVENTION ALWAYS DISCONNECT
THE ELECTRICAL SUPPLY!
Periodically check that all screws are tightly fastened and the
condition of the various guards
V BELTS
After the first few hours of operation it is necessary to check
that the tension of the belts is correct,as they tend to stretch.
To control the tension of the belts push the mid-point of the
belt applying 3-4 Kg of pressure, the displacement should not
exceed 5-6 mm. To adjust the blade tension loosen the nuts A,
FIG. 23, and tighten the nut
D, FIG. 23, this will increase the
tension, tighten the nuts .
It is recommended that the correct blade tension is maintained
as loose belts reduce the motor power and can increase the
braking time. Belts that are too tight can cause the belts to
become hot .
TO CHANGE THE BELTS
Slacken the tension as described above, remove the screw “
B”,
FIG. 22, loosen the screws “
A”,
pull-out the bandwheel and shaft, repeat the operations in
reverse to re-assemble.
IMPORTANT: loosen only the 2 screws indicated so as not to
interfere with the alignment of the fly-wheel.
DISMANTLING THE UPPER FLY-WHEEL
Remove the screw “
E”,FIG.24 and remove fly-wheel and shaft
from their positions.
REPLACEMENT OF RUBBER COVERING OF
THE FLY-WHEELS
It is recommended that this be carried out by a competent
specialist or the manufacturer, this is because the rubber
covering is not only glued onto the fly-wheel, but also ground in
a crown form. It is strongly advised not to grind and shape the
rubber directly on the machine using gouges, files or abrasives.
CLEANING AND LUBRICATING
Periodically clean the inside of the machine with the aid of a
dust extractor for any saw-dust deposits, remove any resinous
deposits from the fly-wheels surface. The fly-wheel bearings
do not require any greasing. It is not necessary to lubricate any
part or component of the machine as the sawdust circulating
within will adhere to any oiled or greased surface jeopardizing
the sliding of moving parts such as the shaft of the blade guide
adjustment and the slide of the tensioning group.
Frequently control the cleanliness of the rubber surfaces on the
fly-wheels, particularly in cases of cutting resinous materials or
chip-board. Clean the surfaces, while machine is not in motion ,
of any resinous deposits taking care do not damage the surface.
