a. Precautions required
To avoid any incidents, unplug the device before all cleaning operation.
• Clean the tracer covers regularly: use a neutral detergent (e.g. washing-up liquid) diluted with water
on a soft cloth.
• Clean the window of the centering chamber regularly with a dry soft cloth.
• Clean the touch screens with a dry cloth: they must never come into contact with liquids (e.g. water,
alcohol, window cleaner).
• Use protective covers on the machines and keep them dust-free as dust alters the precision and
operation of the machine.
• Do not touch the lens on the optical block as this could affect the performance of the tracer.
• Never clean the tracer with chemical products (e.g. petrol, thinners, solvents).
• Never clean the machine elements (feeler, tracing table) with a wet rag.
b. Cleaning the centering chamber glass
A dirty or scratched glass may cause centering or tracing defects. It must be replaced by a technician.
Take care of it and clean it regularly with a soft cloth.
Whenever possible, leave the standard tripod in position in the centering chamber. It protects the glass.
