Section 4
Maintenance and Diagnostics
Introduction
Hypertherm assumes that the service personnel who perform troubleshooting testing are high-level electronic service
technicians who have worked with high-voltage electro-mechanical systems. Knowledge of final isolation troubleshooting
techniques is also assumed.
In addition to being technically qualified, maintenance personnel must perform all testing with safety in mind. For more
information, refer to the Safety section for operating precautions and warning formats.
Care and handling of the touchscreen
The following tips will help keep the touchscreen functioning at the optimal level:
• To clean the touchscreen, use window or glass cleaner. Put the cleaner on a soft clean rag and wipe
the touchscreen. Never apply the cleaner directly to the touchscreen.
• Avoid getting liquids inside your touchscreen. If liquid does get inside, have a qualified service
technician check it before you power it on again.
• Do not wipe the screen with a cloth or sponge that could scratch the surface.
• Do not use alcohol (methyl, ethyl or isopropyl) or any strong solvent. Do not use thinner or benzene,
abrasive cleaners or compressed air.
WARNING!
ELECTRIC SHOCK CAN KILL
Disconnect electrical power before performing any maintenance.
Only qualified personnel can work inside the CNC cabinet with AC power connected.
See the Safety section in this manual for more safety precautions.
