Bar Screen Rake and Channel

The bar screen check clears debris from the operating floor after lockout and confirms the rake, the spray, and the e-stop. The technician writes the as-found reading and compares it with the last one on the asset. Do not enter the channel. Anything past that line belongs to the site's own procedure, the OEM manual, or a permit. This is the inspection ChatterFix schedules. It is not itself permission to go further.

The Procedure

The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

  1. With the screen locked out, clear debris the site procedure allows from the operating floor
  2. Inspect the rake, spray and motor guard
  3. Confirm the e-stop on the screen
  4. Do not enter the channel
  5. A jammed rake is isolated before anyone reaches past the guard

Why This PM Exists

The bar screen check clears debris from the operating floor after lockout and confirms the rake, the spray, and the e-stop. The technician writes the as-found reading and compares it with the last one on the asset. Do not enter the channel. Anything past that line belongs to the site's own procedure, the OEM manual, or a permit. This is the inspection ChatterFix schedules. It is not itself permission to go further.

What Skipping It Looks Like

A jam gets a reach past the guard because locking it out would take longer than the reach. The round still closes, the number never lands on the asset, and the next person inherits a guess. Do not enter the channel.

Setting the interval

Weekly. A jammed rake is isolated before anyone reaches past the guard. An as-found reading outside the limit the site already published is a finding. It does not become a new setpoint on this work order.
