9 MAINTENANCE
WARNING: 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 QUATTROCODE key-cutting machine does not require special maintenance, it is
advisable to check and, if necessary, replace the parts subject to wear and replace electrical/
electronic parts when faulty (fuses, circuit boards, etc.). Replacement is simple and can be carried
out by the operator, following the instructions given.
WARNING: 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.
Before starting any type of maintenance (checks or replacements), read the instructions below:
- never carry out maintenance operations when the machine is operating
- always disconnect the mains power supply
- follow the instructions in the manual to the letter
- use only original spare parts.

c) fuse E for axis B (rotating clamp)
- replace the 1st ST2DRV module for the X and Y axes (chap. 9.6, page 41)
- replace the 2nd ST2DRV module for the Z and A axes (chap. 9.7, page 42).
