7 MAINTENANCE
ATTENTION: for repairs or replacement of parts for maintenance, the ‘CE’ mark is guaranteed only if original
spare parts provided by the manufacturer are used.
Although the IDEA key-cutting machine does not require special maintenance, it is advisable to check and,
if necessary, replace the parts subject to wear and electric/electronic parts (fuses, circuit boards, etc.) in the
event of faulty operation.
ATTENTION: for normal servicing of the burnished mechanical parts, we recommend using lubricants or
protective oil, e.g. WD40 or similar. Do not apply to the parts used for electrical contact (clamps,
decoders, cutters, gauging templates, etc.). Do not contaminate the electronic parts with the oil.
ATTENTION: do not use alcohol to clean plexiglass and plastic parts of the machine.
Replacement is simple and can be carried out by the operator consulting the instructions.
Before starting any type of maintenance (controls or replacements), read the instructions below:
• never carry out maintenance with the machine switched on
• always remove the main power supply cable
• strictly follow all the instructions in the manual
• use original spare parts (see Spare Parts sheet provided).
