Brewer AssistPRO Model 7500 Installation & Operation Manual, Document 101522 Rev D (2025).
Manufacturer Recommendation / AEM Status
Brewer directs facilities to inspect the AssistPRO table every 6 months. Periodic maintenance includes inspection of the electrical, foot-control, and hand-pendant cords; verification of mechanical functions; confirmation that fasteners are present and secure; and lubrication of the back, tilt, and legrest hinges with a food-grade silicone lubricant.
Remove a malfunctioning table from use, unplug it, assist the patient off, and service it before reuse. Use factory-authorized service when repair is required. Apply stricter regulatory or facility requirements where applicable; an alternative interval belongs under the facility's approved AEM program.

Step-by-Step PM Procedure
1. Verify Identity and Configuration
Action: Record asset tag, serial number, Model 7500 designation, department, line rating, installed foot control/hand pendant, accessories, and current programmed-position configuration. Confirm the exact unit falls within the site's AssistPRO 7500 Series taxonomy.
Expected outcome: The chair matches CMMS and the correct manual, controls, accessories, and electrical configuration are identified.
2. Review History and Remove Clinical Load
Action: Review reported motion problems, unintended movement, control issues, interlock events, noises, overheating, fluid exposure, damage, repairs, and prior electrical-safety results. Remove the patient and all clinical load before testing; provide a substitute table if needed.
Expected outcome: The table is safely available for inspection and known defects are identified before powered testing.
3. Clean and Inspect Upholstery
Action: Wipe spills immediately and clean using Brewer-compatible products. Inspect the seat, backrest, headrest, legrest, seams, attachment points, and paper surface for cuts, tears, looseness, staining, chemical damage, or exposed substrate.
Expected outcome: Upholstery is clean, secure, intact, and suitable for patient contact.
4. Inspect Structure, Covers, Fasteners, and Labels
Action: Inspect the base, lift column shrouds, frame, covers, headrest linkage, powered sections, hinges, welds, feet/levelers, and all accessible fasteners. Confirm levelers remain fully engaged at least three turns. Verify safety, load-rating, model, and serial labels are present and legible.
Expected outcome: The structure is stable and undamaged; covers, fasteners, levelers, and labels are complete and secure.
5. Inspect Power and Control Cords
Action: Disconnect mains. Inspect the detachable hospital-grade three-conductor power cord, grounding pin, plug, receptacle, strain reliefs, foot-control cord, hand-pendant cord, locking collars, and connectors for cuts, crushing, exposed conductors, bent pins, heat damage, or loose fit.
Expected outcome: All cords and connectors are undamaged, fully seated, properly retained, and safe for use.
6. Inspect Manual Accessories and Adjustments
Action: Verify the headrest moves through its adjustments and all three over-center handles lock securely. Extend/retract the legrest 5 inches while horizontal, verify both kneeling-height stops engage, and return it fully inward before lowering. Extend, position, lock, and stow both stirrups. Extend/remove/reinstall/stow the treatment pan and verify the paper-roll holder and approved accessories.
Expected outcome: Manual adjustments move smoothly, lock securely, stow correctly, and have no missing or damaged components.
7. Verify Power Switches and Control Power
Action: Connect the table to a correctly polarized grounded 115 VAC receptacle. Turn both backrest-shroud ON/OFF switches ON and confirm both illuminate green. Verify the table operates only when both switches are in the ON, lighted position, as specified by Brewer.
Expected outcome: Both switches, green indicators, grounding connection, and control power operate correctly.
8. Verify Foot Control and Hand Pendant Functions
Action: With the area clear, operate every direction from both controls: TABLE UP/DOWN, BACK UP/DOWN, TILT UP/DOWN, and LEG UP/DOWN. Release each command and confirm motion stops without drift, sticking, unexpected reversal, abnormal noise, binding, or unintended activation. Keep foreign objects away from the controls.
Expected outcome: Every command operates only while intended and all powered motions are smooth, controlled, and free of abnormal behavior.
9. Verify Powered Travel Ranges and Limits
Action: Without exceeding the 10% duty cycle (2 minutes on/18 minutes off), verify table height is approximately 19-40 inches, back motion is horizontal to 85° ±5°, tilt is horizontal to 30° ±5° foot-up, and the legrest travels horizontal to vertical. At each endpoint, verify the actuator stops and does not continue driving when the command remains pressed.
Expected outcome: All four powered functions reach their specified ranges and end-of-travel protection prevents continued actuator operation.
10. Verify Treatment-Pan Interlock
Action: Extend the treatment-pan tray and command LEG UP. Confirm the PAN OUT indicator illuminates and upward legrest motion is inhibited. Fully stow the tray until the interlock click is heard, then confirm legrest-up motion is restored.
Expected outcome: The tray interlock, PAN OUT indication, and restored legrest operation function correctly.
11. Verify Program Storage and Recall
Action: Using the documented hand-pendant and foot-control workflows, store safe unloaded test positions in all four memory locations and recall each position. Confirm the selected program indicator and two-beep storage confirmation operate as described. Restore the facility's original programmed positions after testing.
Expected outcome: All four memory positions store and recall correctly from the applicable controls, with proper indicators/audio and original settings restored.
12. Verify Auto-Run Mode and Stop Controls
Action: In a clear, unloaded area, verify Auto-Run mode changes only after the specified five-second command and two-beep confirmation. During Auto-Run recall, confirm motion stops when STOP is tapped, any foot-control pedal/button is tapped, or any hand-pendant button is pressed. Also verify hold-to-run recall in Auto-Run OFF mode.
Expected outcome: Recall mode, mode indication, emergency interruption paths, and hold-to-run behavior all operate correctly.
13. Verify Built-In Auto-Run Safety Limits
Action: Using safe unloaded programmed motions, verify the Auto-Run safety behavior: downward table movement stops when the stowed legrest is 4 inches above the floor; legrest lowering preserves 1 inch between the actuator and lift-column shrouding; and pelvic tilt stops after 10° of upward movement during the protected recall condition. Do not place hands, tools, or test blocks in pinch points.
Expected outcome: All three documented Auto-Run clearance limits stop motion at the specified thresholds without contact or damage.
14. Inspect and Lubricate Moving Parts
Action: Inspect the back, tilt, legrest, and other accessible pivots/hinges for wear, looseness, binding, or contamination. Apply food-grade silicone lubricant to the back, tilt, and legrest hinges as directed, removing excess and keeping lubricant off upholstery and walking surfaces.
Expected outcome: Required hinges are correctly lubricated and moving parts operate smoothly without excess play or contamination.
15. Verify Ratings, Load Labels, and Thermal Protection
Action: Confirm the label states Class I grounded, Type B, 115 VAC nominal, 60 Hz, 5.8 A maximum, and 10% duty cycle. Verify load-rating labels are legible: seat/back and legrest 450 lb maximum; headrest 100 lb maximum. Do not proof-load the table unless an authorized Brewer procedure requires it. If thermal protection operated during testing, stop and allow 10-15 minutes to cool before re-evaluation.
Expected outcome: Ratings and load limits are legible and consistent with the manual, and no thermal shutdown or overload condition remains.
16. Perform Electrical Safety and Final Restoration
Action: Qualified personnel shall test protective-earth continuity and equipment/patient leakage using the current facility standard for a grounded Class I, Type B device; use the governing acceptance limits because the operator manual does not publish numeric PM limits. Reconnect and secure all controls, restore original memory positions/accessories, clean the table, perform a final functional/interlock check, and document results.
Expected outcome: Electrical safety passes the adopted standard, original configuration is restored, and the table is returned to service with no malfunction or unresolved safety defect.
Electrical Safety Testing
The Model 7500 is a Class I grounded, Type B device with a detachable hospital-grade three-conductor power cord and a nominal rating of 115 VAC, 60 Hz, 5.8 A maximum. Test protective-earth continuity and applicable leakage under the facility's adopted electrical-safety standard and current Brewer service documentation. The public operator manual does not publish numeric PM acceptance values, so do not invent limits; record the standard, analyzer, test mode, readings, and disposition.
