Appendix B – Olivetti S2 printer care and maintenance
Cleaning the printing table
At the end of printing, and after having removed the printed piece, you are advised to clean the printing table,
eliminating residues of hairspray or plastic that could still be present.
To clean the table
you should use normal ethyl alcohol for household use (also known as “ethanol“), and a soft
dry cloth.
NOTE:
The printing table is made of 5 mm thick tempered glass; it is a safety, temperature-resistant, glass.
However, when handling the glass you should pay maximum attention as it is very fragile. Use exclusively
the glass provided with the machine.
Lubricating the axes and spindle nut
The linear guides are lubricated by the grease present in the recirculating ball slides.
The bearings can be injected with lithium-based machine grease through the hole on the slide side. This allows
the grease to penetrate inside the ball recirculation chamber lubricating both the slide and the bar. You should
also spread a little grease on the recesses at the sides of the guide using a dry clean cloth.
The spindle nut operates on a recirculating ball screw which guarantees long resistance over time. To reduce
noise levels and improve operating smoothness, use a dry clean cloth to apply a little grease to the spindle nut.
WARNING: Use exclusively lithium-based grease. Solid lubricants, such as those based on
molybdenum sulphide, must not be used.
Cleaning the feeders
The feeders normally do not need any servicing. However, from time to time it may be opportune to clean the
filament feeder assembly to remove the residues of plastic that have accumulated during machine operation.
To remove plastic dust residues, use a small brush starting from the front slot of the feeder.
One fast efficient method is to use a jet of compressed air either from an air compressor or a compressed air
canister normally used for cleaning keyboards and electronic equipment.
