Maintenance
WARNING: Before effecting any internal inspection of the
SHARK 35 , interrupt the mains power supply.
SPARE PARTS
Original spares have been specifically designed for our equip-
ment. The use of spares that are not original may cause vari-
ations in the performance and reduce the safety level of the
equipment. We are not liable for damage due to use of spare
parts that are not original.
PLASMA CUTTING PLANT
As these systems are completely static except for the fan that
is, in any case, provided with self-lubricating bushes, only the
following operations are necessary:
• Periodic removal of accumulations of dirt and dust inside the
plant using compressed air. Do not point the jet of air directly
at the electrical parts as this could damage them.
• Periodical inspection for worn cables or loose connections
that could cause overheating.
• Make sure the air circuit is completely free of any impuri-
ties and that the connections are tight and free of any leaks.
In this connection, inspect the solenoid valve very carefully.
COMPRESSOR
SHARK 35
does not require an external compressed air sup-
ply as it contains an integrated air compressor which requires
efficacious periodic maintenance to correct and fully explete
its’ function.
Compressor maintenance is limited to cleaning the air filter
which must be dismounted (unscrew and pull it outwards - see
Fig. H) regularly.
Possible problems and remedies
NOTE: Given the technical knowledge required to repair the
plasma cutting plant, in the case of breakage we recommend
contacting qualified personnel or our technical assistance ser­
vice.
The 4 indicator LEDs, located on the SHARK 35 rack panel,
enable, in most cases, identification of the cause of the fault.
We therefore recommend you check the LEDs to identify the
fault.
The faults possible in this plant are listed below with the proba-
ble causes, how to diagnose the same and how to solve prob-
lems rapidly and autonomously. If, however, the fault or problem
remains, contact our technical assistance service.
