What to Check Before Buying a Used Volvo EC210BLC Excavator – A Complete Buyer’s Guide

If you're in the market for a used Volvo EC210BLC excavator, you’re making a smart choice. Volvo excavators are known for their durability, fuel efficiency, and strong resale value. However, buying a second-hand machine requires careful inspection to avoid costly mistakes.

This guide will walk you through the key checks you should perform before purchasing a used Volvo EC210BLC, ensuring you get a reliable machine at the best price.

1. Check the Machine’s Service History & Hours

Verify Engine Hours

• The Volvo EC210BLC typically lasts 10,000+ hours with proper maintenance.

• Low-hour machines (under 5,000 hours) are ideal for long-term use.

• High-hour machines (8,000+ hours) may need major repairs soon.

Review Maintenance Records

• Ask for service logs, oil change records, and part replacements.

• A well-documented history means the excavator was properly cared for.

Check for ECU Error Codes

• Use a diagnostic tool to scan for hidden engine or hydraulic issues.

2. Inspect the Engine & Hydraulic System

 Engine Condition

• Start the engine cold – rough starts or excessive smoke (blue/white) indicate problems.

• Listen for knocking sounds, which may mean bearing or piston issues.

• Check for oil leaks around the engine block.

Hydraulic System Check

• Operate all hydraulic functions (boom, arm, bucket, swing) to test for smooth movement.
• Look for hydraulic leaks (common in hoses and cylinders).
• Check hydraulic oil – dark or milky fluid means contamination.

3. Examine the Undercarriage & Structure

 Track & Rollers Condition

• Worn tracks (below 50% remaining) mean costly replacements.

• Check roller and idler wear – excessive play indicates future repairs.

 Boom, Arm, and Bucket

• Look for cracks or weld repairs (signs of stress or overloading).
• Check pins and bushings – excessive wear affects performance.

4. Test the Cab & Electronics

 Control Response

• Ensure joysticks and pedals respond smoothly.

• Delayed reactions may indicate hydraulic or electrical issues.

Display & Warning Lights

• Check if dashboard warnings (engine, hydraulics, filters) are functional.

• Faulty sensors can hide underlying problems.

Air Conditioning & Comfort

• A broken AC in hot climates reduces operator efficiency.
