5.02 General Maintenance
WARNING
Disconnect primary power to the system before dis-
assembling the torch, leads, or power supply.
To clean the unit, open the enclosure (refer to Section 5.05-
A, Opening Enclosure) and use a vacuum cleaner to re-
move any accumulated dirt and dust. The unit should
also be wiped clean. If necessary, solvents that are rec-
ommended for cleaning electrical apparatus may be used.
This schedule applies to all types of non-liquid cooled
plasma cutting systems. Some systems will not have all
the parts listed and those checks need not be performed.
NOTE
The actual frequency of maintenance may need to be ad-
justed according to the operating environment.
A. Maintenance Schedule
Daily Operational Checks or Every Six Cutting Hours:
1. Check torch consumable parts, replace if damaged

2. Inspect torch for any cracks or exposed wires, re-
place if necessary.
