Recommendations for Machines Sitting Idle Long-Term
- Engine Preservation: Drain fuel or add stabilizers to prevent degradation and injector clogging.
- Fluid Checks: Change hydraulic oil, engine oil, coolant, and other lubricants prior to storage to avoid contamination and corrosion.
- Battery Maintenance: Disconnect batteries and periodically recharge or replace to prevent failure.
- Protective Covering: Shelter the machine indoors or use weatherproof covers to protect from moisture, UV damage, and dust.
- Track and Undercarriage Care: Clean tracks and apply rust inhibitors; periodically move or reposition machine to prevent flat spots or stiffness.
- Hydraulic Cylinder Positioning: Retract hydraulic cylinders to eliminate exposure to elements and prevent rod corrosion.
- Pre-Start Inspection: Upon return to service, thoroughly inspect fluid systems, fuel quality, electrical systems, and moving parts before heavy use.
- Powershift Transmission: A transmission allowing gear changes without clutching, improving operator ease and machine responsiveness.
- Breakout Force: The force a machine can exert to break material loose.
- Hydraulic System: The system of pumps, valves, and actuators providing power to machine implements.
- Undercarriage: The lower portion including tracks, rollers, and frame that supports crawler machines.
- Fuel Stabilizer: Chemical additives preventing fuel degradation during storage.
