5. Maintenance
Warning: before any intervention always disconnect
the electrical supply by plug out!
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.
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 blade tension , remove the screw at the
center of lower bandwheel, pull-out the bandwheel
from the shaft, repeat the operations in reverse to re-
assemble.
- Dismantling the upper bandwheel
Remove the upper bandwheel is same as the operations
of lower bandwheel.
- Replacement of rubber covering of the fly-wheels
It is recommended that this be carried out by a compe-
tent specialist or the manufacturer, this is because the
rubber covering is not only glued onto the bandwheel,
but also ground in a crown form. It is strongly advi-
sed 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, remo-
ve any resinous deposits from the bandwheels surface.
The bandwheel 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 surfa-
ces on the bandwheels, particularly in cases of cutting
resinous materials or chip- board. Clean the surfaces,
while machine is not in motion , of any resinous depo-
sits taking care do not damage the surface.
6. Trouble shooting

lised technical personel.
- Before carrying out any fault service or maintenance
work, please always trun off the switch, unplug power
cable, wait for saw blade to come to standstill.
