1.  Without reference, identify principles relating to Fixed Radiological X-RAY PM with at least 70 percent accuracy.

2.  Introduction  Preventive maintenance consists of procedures that minimize equipment failures  A conscientiously conducted visual inspection frequently reveals potential malfunctions before they cause equipment failure  Preventive maintenance is most effective when it is performed according to a schedule  Generator Maintenance  Semi-annual inspection  Conduct a thorough visual and hands-on inspection of the generator and accessories  Inspect unit for damage, excessive rust to critical parts, bearing tracks and races etc. and excessively worn components  Inspect  All electrical cables  Cords  Connectors  And fittings for tightness

3. Check for breaks in insulation, abrasions and other damage to cables and connectors Thoroughly inspect all high voltage cables and their connections to the x-ray tubes and high voltage transformer Ensure all connections are firmly seated and that there are no signs of arcing Examine the high voltage transformer for indications of oil leakage Examine all exterior painted surfaces for corrosion and ensure all name plates and warning labels are present, legible and securely mounted Test all front panel controls and meters for proper operation and replace any burnt out lamps  Annual Inspection Perform the semi-annual Inspection and ensure that the main circuit breaker is turned off Disconnect the high voltage cables from the high voltage transformer and x-ray tubes Clean the terminals and repack the x-ray tube ends with dielectric silicone grease Repack the transformer ends with dielectric oil until it spills over Check the oil level in the high voltage transformer and add dielectric oil to within 1 inch of the top cover (if necessary)

4.  Table Maintenance (Semi-Annual)  Check all nuts and bolts, screws, rivets and other fasteners for tightness, tighten and replace as necessary  Inspect all electrical cables, cords, connectors and fittings for tightness  Check for breaks in the insulation, abrasions and other damage to cables and connectors  Examine all exterior painted or plated surfaces for evidence of deterioration, chipping and corrosion  Ensure all name plates and warning labels are present, legible and securely mounted  Counterweight cables should be inspected no less than every six months Cable failures can cause serious injuries to patients and operators Worn or damaged cables cannot be repaired Inspect cables for evidence of rust or corrosion Examine both ends of cables for evidence of kinking Inspect for broken strands by running a soft cloth or towel along the entire length of both cables including attachment points.

5.  Broken Strands are Evident if the Cloth Snags at Any Location Along the Cable  Cables must be immediately replaced if there is any evidence of broken or frayed strands, kinks, corrosion or weakness in any mechanical fitting  If the table has motion capabilities an operational check out should be performed IAW manufacturer's literature  All raceways and bearings should be lubricated every six months using a light grade of machine oil such as WD-40

6.  Tubestand Maintenance (Semi-Annual)  Perform a general inspection of entire assembly noting any worn or damaged parts  The exterior of the tubestand should be wiped down with a mild soapy solution and clean, dry cloths to get rid of dust and foreign materials  Check all hardware for adequate tightness and adjust or replace as necessary  Power should be applied to the tubestand and each function should be checked IAW manufacturer's literature  All travel features should be checked for smooth operation and proper movement  All locking and/or braking mechanisms should be checked for proper operation  Inspect all pulleys and repack with lubricant  All bearings and bearing raceways should be inspected and lubricated using a light grade of machine oil such as WD-40  Inspect all cables for fraying, corrosion and excessive wear, replace as necessary
