9 Maintenance and cleaning
Scheduled maintenance and cleaning are prerequisites for a long service
life and trouble-free operation. The maintenance cycle is determined by
the work environment and the device’s maintenance intervals. If the device
is operated for more than 8 hours a day, the maintenance intervals should
be changed as needed. When using plasma arc cutting equipment, always
observe the provisions of EN 60974-4 Inspection and testing, as well as any
local laws and regulations.

• The cover plates may be disassembled and assembled only by a
qualified electrician for maintenance and cleaning work.
• Each time the cover plates are opened, have a safety inspection
performed in accordance with DIN IEC 60974 Part 4: “Periodic
inspection and testing” by Thermacut
