Preparations before Long-Term Storage

Protect the equipment from corrosion and storage damage if the storage is expected to last three months or longer. If environment is, for example, corrosive or dusty, extra protection is necessary.

  • Wash the equipment thoroughly and wipe it dry. Use compressed air to blow any collections of water out of cavities and pockets.

  • Protect from rain, snow, and strong sunshine. Keep regulated temperature and ventilation. Recommended storage environments must maintain a temperature of 10–20 °C (50–68 °F) and maximum 20–50% humidity. Storage site must be free from severe vibration to avoid spot damage to the equipment.

  • Apply corrosion inhibitor (For example, Tectyl 506) to machined surfaces.

  • Apply touch-up paint to any scratches and damage on painted areas.

  • Cover all equipment with plastic sheet.

  • Clean old lubricant grease from lubrication points to prevent coke formation. Apply lubricant grease into the lubrication nipples. Apply lubricant grease with a brush to sliding surfaces and splines where it occurs. Use the correct lubricant grease for each point.

  • Observe the strictest cleanliness when disassembling hydraulic, compressed air, and water flushing hoses. Immediately plug all hoses, nipples and hydraulic oil pipes, or seal and protect them from dirt in some other suitable way.

  • Mark hoses, pipes, and other connections to make reassembly easier and prevent mix-ups.

  • Hoses and rubber parts must be packed in air-tight plastic to reduce aging and drying. Make sure that the components are dry before packing.

  • Fill fuel tanks and oil tanks.

Prepare Electrical System for Long-Term Storage

If the temperature falls below freezing point, the battery must be stored indoors.

  1. 1.
    Disconnect the battery terminal connections.
  2. 2.
    Clean and grease battery terminal connections.

Prepare the Feed for Long-Term Storage

The feed must be stored in a dry and clean environment.

  1. 1.
    Clean the feed thoroughly.
  2. 2.
    Lubricate the feed.
  3. 3.
    Protect unpainted surfaces with rust inhibitor.
  4. 4.
    Store the feed in a dry and clean environment.

Prepare the Rock Drill for Long-Term Storage

See Reference Documentation

Maintenance manual for rock drill

Prepare the Water Mist System for Long-Term Storage

  1. 1.
    Drain the water mist system.
  2. 2.
    Rinse with anti-freeze.
  3. 3.
    Blow dry the water mist system with compressed air.

Restoring after Long-Term Storage

  • Change lubricant and hydraulic oil where appropriate.

  • Change filter and drain water separators where appropriate.

  • Inspect joints, bushings, and splines for corrosion. Remedy any corrosion by cleaning or replacing components.

  • To remove any moisture binding from lubrication points: Pump new grease into the grease nipples and apply grease with a brush to splines and sliding surfaces. Use the correct grease for each point.

Inspection and Maintenance during Long-Term Storage

  • Check levels for oils and coolants.

  • Start the diesel engine and run until the normal operating temperature is reached.

  • Operate the machine a few metres back and forth so that the tramming gears are lubricated.

  • Operate the tilt cylinders, boom, feed, drill rod support, and rod handling until all cylinders reach their end positions.

  • Drain condensed water from the hydraulic oil tank and compressor oil tank.

  • Rotate the electric motors a few turns at least every three months to avoid spot damage on motor bearings.
