OSSM Safety and Emergency Stop

Prevent pinch, impact, stability, electrical, and unexpected-motion hazards and verify the emergency stop before use.

OSSM creates fast, forceful reciprocating motion. Read this page before first use and whenever the machine, mount, attachment, controller, or firmware changes.

Unexpected motion can cause serious injury

Hazard: the moving rail, carriage, belt, and attachment can create pinch, crush, impact, or entanglement points. Consequence: contact can cause serious injury. Avoidance: keep people, hair, cables, clothing, and loose objects clear; stabilise the machine; begin at zero speed and depth; keep a tested Stop control within reach.

Mandatory pre-use checklist

  1. Inspect the frame, belt, rail, fasteners, cables, power supply, and attachment. Do not use damaged, loose, unusually noisy, or contaminated parts.
  2. Place the machine on a stable surface and weight the base with a filled sandbag or an equally secure restraint.
  3. Keep the full travel path and all pinch points clear.
  4. Attach only a secure, material-compatible accessory and check it cannot detach through the planned range.
  5. Set speed and depth to zero before connecting power or a controller.
  6. Power on without a person in the motion path and allow homing to finish.
  7. Test at the lowest practical speed and depth while unloaded.
  8. Trigger the controller's Stop action and confirm the carriage stops before positioning a person.

Pause is not a substitute for removing power before cleaning, maintenance, attachment changes, or fault investigation.

During use

  • Increase only one motion setting at a time from zero.
  • Keep the Stop control reachable by the person at risk or a trusted attendant.
  • Never reach into the travel path while powered, even when paused.
  • Stop for unexpected movement, slipping, looseness, heat, burning smell, damaged insulation, unusual noise, loss of controller connection, pain, numbness, or distress.

If something goes wrong

  1. Use the tested Stop control.
  2. Move the person clear only if doing so does not introduce more risk.
  3. Disconnect power when it is safe.
  4. Do not resume until the cause is understood and the unloaded pre-use test passes.
  5. Email support@researchanddesire.com when damage, unreliable stopping, unexpected motion, electrical symptoms, or an unknown fault is involved.
