Frequently Asked Questions

  • What’s included in plant machinery servicing?

    A full plant machinery service generally includes changing fluids, replacing filters, lubricating moving parts, checking hydraulics and hoses, inspecting electrical systems and performing safety checks. Depending on the type of equipment, the technician may also run diagnostic tests, test pressures and perform minor repairs to prevent future issues. Keeping machinery well-serviced improves its lifespan, reduces breakdowns and supports compliance with safety and environmental standards.

  • How do I know if my machinery needs servicing?

    Signs your machinery may need attention include fluid leaks, reduced engine performance, unusual noises, dashboard warnings, or slower hydraulic movement. However, many mechanical issues don’t give early signs at all – which is why regular preventative maintenance is important. It’s generally recommended to service machinery every 250 to 500 operating hours, depending on the model and how it’s used. Regular logbook servicing helps avoid costly downtime.

    Yes – mobile plant servicing is available throughout Shellharbour and surrounding areas.
