MAINTENANCE
WARNING
Before carrying out service, maintenance and/or
repair jobs, fully disconnect power to the machine.
Use Personal Protective Equipment (PPE), including
safety glasses, dust mask and gloves to avoid
injury. This also applies to persons who enter the
work area.
MOVING PARTS can injure.
• Do not operate with doors open or guards off.
• Stop engine before servicing.
• Keep away from moving parts.
Have qualified personnel do all maintenance and
troubleshooting work.
vIsUal InspeCTIOn
Clean interior of machine with a low pressure air stream. Make a
thorough inspection of all components.
Look for signs of overheating, broken leads or other obvious
problems. Many problems can be uncovered with a good visual
inspection.
rOUTIne MaInTenanCe
Every six months the machine should be cleaned with a low
pressure air stream. Keeping the machine clean will result in
cooler operation and higher reliability. Be sure to clean the
following areas:
• All printed circuit boards
• Power switch
• Main transformer
• Input rectifier
• Heatsink fins
• Auxiliary Transformer
• Fans (Blow air through the rear louvers)
Examine the sheet metal case for dents or breakage. Repair the
case as required. Keep the case in good condition to ensure that
high voltage parts are protected and correct spacing is maintained
throughout. All external sheet metal screws must be in place to
ensure case strength and electrical ground continuity.
If for any reason you do not understand the procedures or are unable to perform the maintenance or repairs safely, contact your
Lincoln Authorized Service Facility for technical troubleshooting assistance before you proceed.
