Observe operating screen for any panels with 'dead spots' where material is puddling.

Replace wire panels that no longer maintain tension over the complete surface area.

Screen Tension and Buffer Check

Check that screen is tight against all buffer and crown bars.

Replace rubber on crown bars if missing, torn, or worn through to the metal.

Ensure cross bracing is provided if all support frames and drive unit/shaft casings are removed.

Cut the huck bolts holding the wire frame to the vibrating frame side walls at the four corners and temporarily replace them with bolts, nuts, and washers.

Remove the breather assembly from the top of the bearing housing by unthreading the complete assembly at the threaded bushing.
