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 EX-TRAFIRE
®
105HD’s maintenance
intervals. If it is operated for more than eight 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.
Electric shock due to missing grounding
If the cover plates are improperly mounted, the grounding may not be
properly established. There is a risk of life-threatening electric shock.
The cover plates may be disassembled and assembled only by a
certified electrician or trained personnel for maintenance and cleaning
work.
Verify the grounding has been established correctly.
Electric shock due to live parts
Fatal electric shock can occur if components are live during maintenance
and cleaning work.
Set the POWER switch to OFF before maintenance and cleaning work.
Disconnect the input power supply from the wall.
Observe the Lock-out/Tag-out procedure.
Electric shock due to defective cables
Damaged or improperly installed cables can lead to fatal electric shock.
Check all live cables and connections for proper installation and
damage.
Damaged, deformed or worn parts should only be replaced by a
certified electrician or trained personnel.
Fire hazard due to contamination
Dust deposits inside the EX-TRAFIRE
®
105HD can lead to a reduction in
insulation. This can cause short circuits or fires.
Clean the power supply annually with dried compressed air to remove
dust and cutting fume residue.
