9. Maintenance
BEFORE ANY INTERVENTION ALWAYS DISCONNECT THE MACHINE FROM THE ELECTRICAL SUPPLY.
Periodically check that all screws are tightly fastened and the condition of the guards are acceptable.
V Belts
After the first few hours of operation it is necessary to check that the tension of the belts is correct as they may have stretched. 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 become hot.
To Change the Belts
Slacken the blade tension, remove the screw at the centre of lower bandwheel, pull out the bandwheel from the shaft. Repeat these operations in reverse to
re-assemble.
Dismantling the Upper Bandwheel
Removal of the upper bandwheel requires the same procedure as on the lower bandwheel.
Replacement of the Rubber Covering of the Fly-Wheels
It is recommended that this be carried out by a competent specialist or the manufacturer due to the rubber covering being glued onto the bandwheel and
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 of sawdust with the aid of a dust extractor. Remove any resin deposits from the bandwheels' surfaces. 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 assembly.
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 resin deposits and take care do not damage the surface.
