Shiny steel particles give an indication of pump failure or motor piston failure.
Rubber particles indicate a seal failure or a hose failure.
Aluminum particles give an indication of a pump or motor failure. Check the following components: a material feed charge pump, a fan drive motor, a ventilation fan motor and a tamper drive motor. Note: If any of these particles are found in the filter element, all components of the hydraulic oil system must be cleaned. Do not use any damaged parts. Any damaged parts must be removed and new parts must be installed.
