Standard 3085 SP, IPX4 production, HERMES/ACT-enabled configurations, and 3085 SP ConverTable Bariatric only when the corresponding manual applies.
Manual References
Use the operator manual for the exact model/serial; maintenance manual P764328948 before S/N B420702-025; P764332897 after S/N B420702-025 (IPX4); and P150830-476 for ConverTable Bariatric.
Manufacturer Recommendation / AEM Status
STERIS requires regularly scheduled preventive maintenance. The published ConverTable Bariatric schedule calls for twice-yearly operator review, structural/caster/floor-lock/hydraulic/control/articulation inspections and annual lubrication, cable/connector, charger, and battery checks. Increased use may require more frequent maintenance.
Confirm the exact serial number and configuration before work. Do not apply ConverTable-only parts, voltages, spacers, load limits, or adjustments to a standard 3085 SP. Any interval change must follow the facility's approved AEM program and risk assessment.

Step-by-Step PM Procedure
1. Verify the Exact Table and Manual
Action: Record asset tag, model, serial, manufacture/configuration identifiers, electrical rating, patient-load rating, controls, top/pads, and accessories. Determine whether the table is before or after S/N B420702-025 and whether it is ConverTable Bariatric.
Expected outcome: CMMS identity and the correct specifications, schedule, parts, and manuals are confirmed.
2. Review History and Remove From Use
Action: Review positioning, lock, battery, charger, control, hydraulic, drift, leak, collision, and electrical complaints. Remove the patient and unsecured accessories and establish a controlled service area.
Expected outcome: Known trends are identified and clinical use is prevented during service.
3. Establish a Safe Service Condition
Action: Stabilize and lock the table, disconnect mains for visual/internal inspection, and control stored energy. Never work under an unsupported section. Restrict internal, hydraulic, battery, and adjustment work to qualified personnel.
Expected outcome: Movement, crushing, electrical, tipping, and load hazards are controlled.
4. Inspect Overall Condition
Action: Inspect tabletop, frame, column, base, welds, shrouds, bellows, covers, rails, labels, connectors, finish, and hardware for damage, corrosion, impact, fluid intrusion, sharp edges, looseness, or missing parts.
Expected outcome: Structure and labels are complete, intact, stable, and safe.
5. Inspect Pads, X-Ray Tops, and Supports
Action: Inspect pads, retainers, seams, cores, X-ray tops/standoffs, headrest, leg section, attachment points, and locks for damage, contamination, fluid ingress, compression, or lost retention.
Expected outcome: Patient supports are intact, cleanable, secure, and correctly installed.
6. Inspect Rails and Attachments
Action: Inspect rails, spacers, fasteners, welds, and clamps; tighten only to current specifications. ConverTable Bariatric uses special side-rail spacers—do not substitute standard 3080/3085 spacers.
Expected outcome: Rails, spacers, and accessories are compatible, undamaged, and secure.
7. Inspect Casters, Floor Locks, and Foot Pads
Action: Clean and inspect casters, tread, bearings, pivots, fasteners, foot pads, rolling, and steering. Engage locks and apply controlled force in multiple directions. Lubricate annually only as directed.
Expected outcome: Casters move freely, locks hold securely, and foot pads are complete.
8. Inspect the Hydraulic System
Action: Qualified personnel inspect reservoir/oil level, pump, hoses, cylinders, fittings, manifolds, valves, and nearby surfaces. Use only specified oil; correct the cause of any leak.
Expected outcome: Oil level meets the exact manual requirement and the system is intact and leak-free.
9. Inspect Power and Control Components
Action: Inspect cord, plug, strain relief, inlet, protection devices, grounding contact, controls, connectors, interfaces, and accessible wiring. During annual qualified inspection, confirm connectors are secure and cables are not frayed.
Expected outcome: Components are correct, secure, and free of heat, arcing, exposed conductors, bent pins, or intermittent connections.
10. Verify Floor-Lock Interlock and Stability
Action: Unloaded and with the area clear, verify permitted articulation conditions and that locks remain engaged. Never use auxiliary override unless floor locks are engaged.
Expected outcome: The table remains rigid and stationary and applicable interlocks operate correctly.
11. Verify Primary-Control Articulations
Action: Exercise every fitted function through full travel: height, Trendelenburg/reverse, lateral tilt, back, leg, flex/reflex, level, and orientation-specific functions. Check direction, indicators, stops, smoothness, and holding.
Expected outcome: Every function moves and stops correctly without drift, jerking, noise, collision, or unintended motion.
12. Verify Foot Control When Fitted
Action: Exercise all fitted foot-control functions and inspect pedal return and connector retention. Releasing the control must stop motion.
Expected outcome: Commands are correct and stable with no simultaneous or opposite movement.
13. Verify Auxiliary Override and Manual Pump
Action: With locks engaged, test override and manual hydraulic foot-pump functions exactly as specified, then restore covers and controls.
Expected outcome: Backup positioning works and no control remains stuck, disconnected, or enabled.
14. Verify Battery Operation
Action: Disconnect AC and verify required articulations. Inspect indicators, battery age, terminals, cables, restraint, swelling, leakage, corrosion, and heat. Replace only as an approved matched set.
Expected outcome: Battery operation is reliable and batteries/connections are serviceable.
15. Verify Charger and Battery Voltage Annually
Action: Measure at exact points specified. For documented ConverTable Bariatric only: motor charger 28.5 V ±1% at P20, control charger 28.3 V ±1% at S1/S5, and fully charged battery 13.6–13.8 V per battery at 77°F (25°C).
Expected outcome: Results meet the exact serial/configuration specification.
16. Check Tabletop Rigidity and Side-Tilt Play
Action: With locks engaged, check abnormal horizontal/vertical play and inspect the tilt mechanism, clevis, support bracket, pins, bushings, and specified screws using the applicable acceptance procedure.
Expected outcome: The tabletop is stable, play is within specification, and hardware is secure.
17. Lubricate Column Guide Rails Annually
Action: Qualified personnel apply only the specified product, location, preparation, and amount; protect surfaces and remove excess.
Expected outcome: Rails are correctly lubricated without contamination.
18. Verify Interfaces and Accessories
Action: Test HERMES/ACT, OR controls, specialty tops/extensions, and accessories using their manuals. Verify compatibility, orientation, load restriction, locking, and clearance.
Expected outcome: Installed options are secure and create no collision, tipping, pressure, or overload hazard.
19. Perform Electrical Safety Testing
Action: Perform protective-earth continuity/resistance and applicable chassis/touch leakage tests using the current STERIS procedure and facility standard. Record the standard, measured values, and limits; no universal limit was established by the reviewed operator schedule.
Expected outcome: Applicable measurements meet approved limits.
20. Restore and Complete Final Test
Action: Secure covers/shrouds; reinstall pads, tops, sections, cables, controls, and approved accessories. Connect AC, confirm charge, repeat representative primary/battery/override functions, verify locks and level, clean, label, and document.
Expected outcome: The table is complete, clean, stable, charged, functional, and ready for service.
Electrical Safety Testing
Use the exact serial/configuration-specific STERIS manual and current facility standard. Document analyzer/standard, table rating, visual inspection, protective-earth resistance, chassis/touch leakage, required polarity/operating conditions, limits, and pass/fail. Do not invent a universal limit or borrow one from another model.
