Surgical stretcher articulating headrest push handle release/gas spring malfunction

Articulating headrest push handle does not engage/disengage completely or gas spring does not function smoothly

Ranked causes

  1. 1. Gas spring requires adjustment (common)
  2. 2. Gas spring worn or failed (occasional)
  3. 3. Cable routing incorrect after internal maintenance (rare)
First check

Verify gas spring and push handle operation throughout range

Test point
Gas spring and push handle
Expected
Gas spring releases and locks throughout full range; push handle engages and disengages completely; handle returns without binding
