What This Guide Helps With
This guide assists Clinical Engineering in troubleshooting situations where the STERIS AMSCO 3085 SP surgical table exhibits slow movement or hydraulic fluid leaks. Symptoms may include:
- Table moves slower than normal
- Jerky or uneven movement
- Visible hydraulic fluid under or around the table
- Audible hissing or fluid noise during table adjustments
Focus is on external, verifiable issues first, before assuming internal hydraulic failure.
Step-by-Step Troubleshooting
Ensure Patient Safety
- Confirm that the table is empty of patients or personnel.
- Slow movement under load may be normal; troubleshooting should be done unloaded.
Check Power and Controls
- Verify the table is powered on and the hand control/foot pedal functions.
- Confirm indicator lights on pendant respond correctly. Malfunctioning controls can mimic hydraulic issues.
Inspect Hydraulic Lines and Cylinder Areas
- Look for visible leaks around the hydraulic cylinder, hoses, and fittings.
- Wipe areas clean and observe while operating the table to pinpoint leaks.
- Check for loose fittings or damaged hoses.
Check Fluid Levels
- Locate the hydraulic fluid reservoir (refer to external access panel).
- Verify fluid is at proper level; low fluid can cause slow movement.
- Only add manufacturer-specified hydraulic fluid; do not mix types.
Assess External Obstructions or Binding
- Ensure wheels, bearings, and pivot points are clear of debris.
- Observe if mechanical linkages move freely. Dirt or foreign objects can slow movement.
Operate Table Slowly
- Cycle all table motions one at a time while monitoring speed and fluid behavior.
- Note any motion that is slower than others or irregular.
Document Findings
- Record any leaks, unusual sounds, or slow motions for work order.
If the Problem Persists
If external inspections, fluid levels, and linkages appear normal but movement remains slow, or leaks continue:
- Remove the table from service
- Label Out of Service
- Send for repair or bench evaluation
Internal hydraulic components may require repair that should not be attempted bedside. Knowing when to stop is proper troubleshooting.
Clinical Use Tip
- Never operate a hydraulic table with leaks under a patient.
- Always move the patient to another operational table before further troubleshooting.
- Ensure all personnel are clear of moving parts during tests.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
“Table moves slowly and shows hydraulic fluid under base.”
Cause
What was observed during troubleshooting.
Example:
“Observed minor leak at hydraulic cylinder hose fitting; fluid level slightly below recommended.”
Resolution
What action was taken.
Example:
“Table removed from service; leak location documented; sent to vendor repair for hydraulic system evaluation.”
Helpful Details to Include
- Outlet tested for proper voltage
- Pendant/hand control function
- Fluid reservoir level
- Exact location of leak
- Movements tested (tilt, raise/lower, lateral)
- Final device status (OOS, sent for repair)
Final Thought
Proper clinical engineering troubleshooting ensures patient safety and preserves equipment integrity. Start with external and easily verifiable checks, escalate when necessary, and document clearly to support repair and prevent repeat issues.
That is successful troubleshooting.
