8 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 TWISTER II NA key-cutting machine does not require special maintenance, it is advisable to check
and, if necessary, replace the parts subject to wear, such as: the belt (Section 8.1) and the lamp (Section 8.2).
Replacement is simple and can be carried out by the operator.
CLEANING: keep the carriage and clamps free of chippings from the cutting operations by cleaning with a dry
brush.
ATTENTION: DO NOT USE COMPRESSED AIR!
ATTENTION: to keep the machine well maintained we recommend using protective oil, e.g.
WD40 or similar, applied to the burnished mechanical parts. This prevents oxidation of the
parts in question (clamps, guides, carriages, etc.).
Before starting any type of maintenance (checks or replacements), read the instructions below:
• never carry out maintenance or servicing with the machine switched on.
• always unplug the machine prior to servicing.
• follow all the instructions in the manual to the letter.
• use original spare parts.
