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 DELTA 2000 SA key-cutting machine does not require special maintenance, it is advisable
to check and, if necessary, replace the parts subject to wear (cutting tool, brush, tracer point).
Replacement is simple and can be carried out by the operator.
CLEANING: it is advisable to use a soft brush to keep the carriage and clamps free of chippings from
cutting operations.
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 remove the mains plug.
• follow all the instructions in the manual to the letter.
• use original spare parts.
• always check that any screws or nuts removed when replacing a piece are properly
tightened.
