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 uper bandwhel
Remove the upper bandwheel is same as the operations of lower bandwheel.
Replacement of ruber 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 bandwheel, 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 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 surfaces on the bandwheels, particularly in cases
of cutting resinous materials or chipboard. Clean the surfaces, while machine is not in motion , of
any resinous deposits taking care do not damage the surface.
