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 DUO 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, cutting tool, brush, tracer point.
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 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.
