Maintenance Management and Hour Meters

Maintenance management is organized in scheduled intervals.

Scheduled intervals supplement each other. A longer interval comprises maintenance tasks supplementary to tasks from a shorter interval. Maintenance management must be done regularly at the shortest interval of the unit or function (whichever comes first during operation of the machine).

Operational maintenance is planned based on the following hour meters:

• Hour meters for the rock drill operation system

• Hour meter for the engine

• Time-based maintenance is vital for:

  • All rubber components

  • Lubricants that are at risk of breaking during standstills

  • Pressure vessel corrosion and wear

  • Substance regression

  • Environmental exposure

• Hour meter for the electrical motor.

• Calendar based maintenance applies to all rubber components, lubricants that are at risk of breaking up during stand stills, pressure vessels corrosion and such where age, substance regression and environmental exposure are vital to maintenance factors.

Maintenance Records

• Correct record keeping enables maintenance personnel to identify the correct maintenance records and to evaluate problems and high-cost areas.

• All maintenance procedures must be checked off as each inspection or procedure is completed.

• Quantities of replenished lubricants and fluids, and pressure and flow readings, must be recorded.

• Any faults or deviations must be recorded irrespective of whether they have been rectified or are waiting for rectification.
