Preventive Maintenance Schedule
This program lists the necessary preventive maintenance operations and specifies the frequency with which
these operations are to be performed.
Daily or Every 8 Hours
 Make a visual inspection of the machine. Check that there are no missing or damaged parts, or
abnormal vibrations.
 Check the guards and covers. Repair any damaged ones and replace any missing ones.
 Check the pressure in the air supply system on the pressure gauge of the pneumatic control unit.
This is also the pressure of the air on the air bearings.
 Check the devices for automatically cleaning the filters of the pneumatic control unit.
 If necessary, clean the work table with heptane or isopropyl alcohol. Use a clean, soft and lint-free
cloth (such as medical gauze or equivalent material).
 If necessary, clean the optical scales and the guideways (only those without protection and
therefore readily accessible).
 Check that the Z-rail is correctly counterbalanced, after starting the machine and assembling the
head and tools.
Monthly or Every 165 Hours
 Check that the emergency buttons and safety devices (optional laser scanner) are working properly.
 Make a visual inspection of the machine. Check that there are no missing or damaged parts, or
abnormal vibrations. Tighten any loose screws and nuts. Replace any missing screws or nuts.
 Check the cable of the portable Jogbox programming unit: its outer sheath must be undamaged
and the single wires inside it must not be visible, especially near the connector and the connection
with the portable unit. In case of damage, it is to be replaced immediately to avoid the risk of the
emergency stop device of the Jogbox or the Jogbox itself malfunctioning.
 Clean the optical scales and the guideways of all the axes (where necessary, remove the guards
covering them).
 Check the devices for automatically cleaning the filters of the pneumatic control unit.
 Clean the structure and painted guards of the measuring machine; use industrial detergents soluble
in water (the use of other products may cause damage to the paintwork). Prevent the detergent
liquid from coming into contact with the other components of the measuring machine (for example,
guideways, optical scales and racks).
