Maintenance Guide
- Inspect track roller oil level quarterly; any oil leakage indicates seal failure requiring immediate replacement to prevent internal contamination.
- Monitor sprocket tooth wear; replace sprocket when tooth tip width reaches 20% of original to avoid chain damage.
- Check track chain tension frequently; over-tensioning accelerates wear, under-tensioning causes derailment.
- Grease idler tension adjuster every 500 hours using recommended lithium-based grease.
- Replace full undercarriage system after 4,000–6,000 working hours for optimal cost-efficiency.
