Common Issues, Maintenance Tips & Solutions

• Stalling & Revs Dropping (Perkins-Powered Units)
  One user shared an intermittent stalling issue—rev drop whenever a control lever was used, with smooth starts otherwise. Diagnosis focused on:
  • Fuel system cleanliness
    
  • Potential vacuum forming due to tank vent blockage
    
  • Ingress jamming the check valve
    Recommended actions: open tank when stalling occurs, clean tank and fuel lines, inspect for air leaks.
    
• Hydraulic Performance & Oil Contamination
  Emulsified or contaminated hydraulic oil can reduce ram effectiveness. Ensuring clean lines and thorough bleeding of the boom elbow area is crucial.
  
• Cosmetic Wear – Paint & Corrosion
  Exterior metal parts can experience chipping and rust. Restoring a pristine look involves sandblasting, wet sanding, priming, and applying multiple industrial-grade paint coats. A detailed respray may take ~17 labor hours and ~$300 in paint supplies.
  

Real-World Stories & Anecdotes

• “Worth Every Pound”: Longevity in Action
  A long-term owner described his 2001 JCB 8015 as inexpensive and exceptionally dependable. He stressed that its cheap parts and solid after-market availability make it one of the most cost-effective machines for sustained use.
  
• Cautionary Tale: A Hedge Trimming Gone Wrong
  Another user attempted to stand in the bucket to trim a hedge and noticed a sway—about four inches of laxness in the slew—likely due to wear in slew brakes or ring gear. A strong reminder: it’s safer to stay on stable ground or use proper platforms.
  

Maintenance & Buying Checklist

• Inspect Before Purchase
  • Examine pins and bushes for excessive play or wear
    
  • Watch for fresh paint disguising structural issues
    
  • Test drive and run for ~10–15 minutes—some leaks only appear when hot
    
• Fuel System Health
  • Clean tank, inspect/replace filters, ensure proper vent airflow
    
  • Watch for stalling or hesitations during operation
    
• Hydraulic Integrity
  • Replace contaminated oil, bleed system components, and use correct spec fluid
    
• Durability Considerations
  • Regular lubrication of slew components
    
  • Monitor paint wear and rust—respray when needed to prevent corrosion
