5.01 Routine Maintenance & Inspection
The only routine maintenance required for the Fabricator 251 is a thorough cleaning and inspection, with the fre-
quency depending on the usage and the operating environment.
WARNING
Disconnect the Fabricator from the Input power supply voltage before disassembling.
Special maintenance is not necessary for the control unit parts in the Power Supply. If these parts are damaged for any
reason, replacement is recommended.
CAUTION
Do not blow air into the Power Supply during cleaning. Blowing air into the Power Supply can cause metal
particles to interfere with sensitive electronic components and cause damage to the Power Supply.
To clean the Power Supply, disconnect it from the mains supply voltage then open the enclosure and use a vacuum
cleaner to remove any accumulated dirt and dust. The Power Supply should also be wiped clean. If necessary, sol-
vents that are recommended for cleaning electrical apparatus may be used.
Troubleshooting and repairing the Fabricator should be carried out only by those who are familiar with electrical
equipment.
WARNING
Do not attempt to diagnose or repair unless you have had training in electronic measurement and trouble-
shooting techniques.
