Preventative Maintenance Checklist for Second-Hand Machinery

by Sam from Dige International Trading

Preventative maintenance is the key to avoiding unexpected breakdowns—especially with second-hand heavy machinery. At Dige International Trading, we encourage all buyers to follow a structured maintenance checklist to keep their used equipment running efficiently. This approach can help avoid major repairs and improve equipment reliability on job sites.

Why Preventative Maintenance Matters

Used machines may already have components close to the end of their life cycle. Without preventative measures, a small issue like a cracked hose or worn seal can lead to hydraulic failure or engine seizure. Preventative maintenance identifies and fixes these risks early, saving both money and downtime.

The Ultimate Daily/Weekly Checklist

Daily Checks:

• Inspect fluid levels: engine oil, hydraulic oil, coolant, and fuel.

• Look for leaks under the machine and around hoses.

• Test warning lights and dashboard indicators.

• Check the air filter and clean if necessary.

• Walk around the machine and look for any visible damage.

Weekly Checks:

• Grease all required fittings and joints.

• Inspect undercarriage and track tension.

• Check battery terminals and clean if corroded.

• Examine bucket pins, bushings, and attachment mounts.

• Test all safety features including alarms and lights.

By following this simple routine, you prevent problems before they escalate.

Monthly and Seasonal Maintenance

Monthly:

• Change engine oil and replace oil filter.

• Inspect hydraulic lines for soft spots or wear.

• Examine cooling system and flush if needed.

• Review wear on tires or track pads.

Seasonal:

• Test and recharge the battery in cold climates.

• Replace fuel filters and clean the fuel tank.

• Check and update the machine software (if applicable).

• Clean radiator and air intake areas to prevent overheating.

Track Everything in a Maintenance Log

Keeping a consistent log ensures you never miss a key service interval. It also builds resale value when it’s time to upgrade your fleet. Many professional buyers now ask for a maintenance history before committing to purchase.
