Symptoms

Carbon fiber top damaged caution

Visible wear, cracks, delamination, or splinters on carbon fiber surface, especially at siderail-to-top joint

Ranked causes

1. Surface wear, cracking, delamination or splinters (occasional)
2. Siderail-to-top joint separation or voids (occasional)

First check

Inspect carbon fiber top for damage

Test point: Entire carbon fiber surface, especially siderail-to-top joint
Expected: Free of wear, cracks, delamination or splinters; joint securely bonded without voids

Table top rotation is restricted or stiff caution

Top does not rotate freely at 5 degree Trendelenburg and Reverse-Trendelenburg positions at any frame height

Ranked causes

1. Gimbal friction or mechanical binding (occasional)
2. Excessive rotation beyond design limits causing damage (rare)

First check

Verify free rotation at 5 degree Trendelenburg with top in 3rd highest position

Test point: gimbal or rotation mechanism
Expected: top rotates freely at 5 degree Trendelenburg and Reverse-Trendelenburg

Gimbals not functioning

Gimbals do not rotate freely or fail to return to center position

Ranked causes

1. Gimbal binding or mechanical failure (rare)

First check

Verify gimbals rotate to stops and return to center

Test point: gimbal assembly
Expected: rotate freely to stops and return to center position

Gimbals not secure or not rotating properly caution

Gimbals loose, not rotating to stops, or not returning to center position

Ranked causes

1. Gimbal mounting loose or internal wear (unknown)

First check

Verify gimbal security and rotation

Test point: Gimbals
Expected: Gimbals secure, rotate freely to stops and return to center position

Table top contaminated or labels damaged patient safety

Table top visibly soiled, hazardous contamination present, or instruction labels worn/illegible

Ranked causes

1. Inadequate cleaning or label wear (common)

First check

Inspect table top for contamination and label condition

Test point: Table top surface and all labels
Expected: Clean surface without hazardous contamination; all labels intact and legible

Table top does not fit or lock on H-frame patient safety

Table top cannot be positioned on removable H-frames or T-pins do not slide into locked position freely

Ranked causes

1. H-frame mounting mechanism misaligned or damaged (occasional)

First check

Test table top fit and locking on H-frame

Test point: T-pins and H-frame mounting slots
Expected: Table top fits in all positions; T-pins slide into locked position freely

Table top does not fit properly on H-frames patient safety

Top cannot be positioned on removable H-frames or T-pins do not slide into locked position freely

Ranked causes

1. Improper alignment or obstruction of T-pins (occasional)

First check

Verify top fits in all positions on H-frames

Test point: top-to-H-frame connection at multiple heights
Expected: fits in all positions

Table top does not rotate at Trendelenburg angles in elevated position caution

Table top cannot rotate freely at 5 degree Trendelenburg or Reverse-Trendelenburg when positioned 3rd from highest on H-frame

Ranked causes

1. Friction or mechanical resistance in gimbal rotation (occasional)

First check

Test rotation in elevated position

Test point: Table top rotation with base at 3rd from highest position
Expected: Rotates freely at 5 degree Trendelenburg and Reverse-Trendelenburg

Table top does not rotate at Trendelenburg angles in lowest position caution

Table top cannot rotate freely at 5 degree Trendelenburg or Reverse-Trendelenburg when positioned at lowest point on H-frame

Ranked causes

1. Friction or mechanical resistance in gimbal rotation (occasional)

First check

Test rotation in lowest position

Test point: Table top rotation with base at lowest position
Expected: Rotates freely at 5 degree Trendelenburg and Reverse-Trendelenburg

Table top is contaminated or damaged patient safety

Top shows signs of hazardous contamination, labels are missing or illegible, or carbon fiber exhibits wear, cracks, delamination or splinters

Ranked causes

1. Carbon fiber surface degradation (occasional)

First check

Inspect table top for cleanliness and contamination signs

Test point: entire carbon fiber surface
Expected: clean, without signs of hazardous contamination
