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 electronic marking machine MARKER 2000 does not require special maintenance, it is
advisable to check and, if necessary, replace the parts subject to wear (belt, marking punch, etc.) and
electrical/electronic parts (fuses, circuit boards, etc.) in the event of faulty operation.
Replacement is simple and can be carried out by the operator.
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, 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 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
