and services should be performed as often as indicated
in the chart.
Table 3-1. Scheduled Maintenance Chart
Interval Inspection or Service What to Do
Semi-annually Obvious damage Visually check condition of surgical table for obvious damage such as: cracks in components,
missing components, dents in components, or any other visible damage which would cause
surgical table to be unsafe to operate or would compromise its performance. Repair surgical
table as necessary.
Fasteners / hardware Check surgical table for missing or loose fasteners/hardware. Replace any missing hardware and
tighten any loose hardware as necessary.
Warning and
instructional decals
Check for missing or illegible decals. Replace decals as necessary.
Pivot points/ moving
parts/ accessories
Lubricate all exposed pivot points, moving parts, and accessories with silicone based lubricant.
Hydraulic hoses, tubes,
and fittings
Check all hydraulic hoses, tubes and fittings for leaks. Replace any components causing leaks.
Replace and hoses or tubes with fraying, kinks, cuts, holes, or other damage.
Hydraulic components Run all functions and check hydraulic components for proper operation. Check hydraulic
cylinders for proper speed (Refer to Table 1-1). Clean or replace components as necessary.
Column assembly Run column assembly all the way up and all the way down. Check if column cylinder "jumps"
downward with a loud noise when lowered from top height (oil volume too high in column cylinder
slave line, resulting in overcompressed oil). Check if column cylinder raises table as high as it
should - 43.9 in. (11.5 cm). If necessary, adjust oil level in column cylinder slave line. Refer to
para 4.7. Check for binding or excessive sideways play in column assembly. Replace column
assembly if necessary.
Seat cylinders
synchronization
Remove seat section board and run seat function up and down. Use a straightedge to check if
seat cylinders are synchronized. If not, synchronize seat cylinders. Refer to para 4.6.
Floor lock cylinders Check that floor lock cylinders extend fully and do not bind. If not, disassemble suspect floor lock
cylinder, clean, lubricate with silicone based lubricant, and reassemble. Refer to para 4.25.
Casters Check that casters roll and swivel freely. If not, disassemble casters, clean, lubricate with
silicone based lubricant, and reassemble.
Hand control Operate all functions using hand control and check for malfunctions. All functions should move
as depicted on hand control. When LEVEL button is pressed, table should return to level position
± 2°. If not, calibrate level position. Refer to para 4.3.
Foot control Operate all functions possible using foot control. If foot control is not operating properly, replace
components as necessary.
Emergency override
panel
Operate all functions possible using emergency override panel. If all functions do not work,
replace components as necessary.
Latching mechanism Check latching mechansim for proper operation. Make sure a table section is automatically
captured by latching mechanisms when inserted. If not, remove latching mechanism, clean,
lubricate with silicone based luricant, and reassemble. Refer to para 4.45.
Cushions Check for rips, tears, or excessive wear. Replace cushions as necessary.
Accessories Check that all accessories have all of their components and that they function properly. If
necessary, repair or replace the accessory.
Operational Test Perform an Operational Test to determine if the surgical table is operating within its specifications
(Refer to para 2.1). Replace or adjust any malfunctioning components.
Every Six Years Reservoir strainers Replace reservoir strainer for each pump unit. Refer to para 4.27.
Discharge Filter Replace discharge filter. Refer to para 4.24.
