Short answer

An excavator 250-hour service checklist records the first-tier scheduled service on a tracked hydraulic excavator: engine oil and filter, air and fuel filters, hydraulic checks, track tension, greasing, electrics and safety device tests, signed by the fitter. It is done every 250 engine hours, roughly every 4 to 6 weeks of full-time work. Regulation 213 of the model WHS Regulations requires maintenance by a competent person following the manufacturer's recommendations.

Checked against Model WHS Regulations as at 5 December 2025 (cited within as the Work Health and Safety Regulations 2011) on by the MapTrack templates team. How we check templates

Key takeaways

  • The MapTrack excavator 250-hour service procedure contains 27 checks across 7 sections. Sections covered: Engine, Hydraulic System, Undercarriage / Tracks, Lubrication, Electrical, Safety Devices, Structural.
  • Covers engine oil and filters, hydraulic checks, greasing, tracks and attachments at the 250-hour mark, recorded against the hour meter.
  • Hours, not weeks, drive the interval. An excavator idling on site accrues engine hours without moving, and the calendar hides it.
  • Check track tension and undercarriage wear every service. Small changes there can become costly repairs if they go unrecorded.
  • Under the model WHS Regulations the duty to maintain plant in safe condition sits with the PCBU, and this record is the evidence.

What is an excavator 250-hour service procedure?

A 250-hour service is the first tier of scheduled preventive maintenance for a tracked hydraulic excavator. It is performed every 250 engine hours (or approximately every 4-6 weeks of full-time operation) and is classified as a minor service. The procedure covers engine oil and filter replacement, air filter inspection, fuel system maintenance, hydraulic system checks, track tension adjustment, greasing all pivot points and bearings, electrical system checks and safety device testing. Unlike a daily pre-start check (which confirms the machine is safe to operate), the 250-hour service involves actual maintenance actions: draining and replacing fluids, replacing filters, adjusting components and measuring wear. It is typically performed by a qualified mechanic or fitter, not the operator.

Under the WHS Regulations 2011 (Part 5.1, regulation 213), the person with management or control of plant must ensure its maintenance, inspection and, if necessary, testing are carried out by a competent person, in accordance with the manufacturer's recommendations or, where there are none, the recommendations of a competent person. AS 20474.5:2025 sets safety requirements for how hydraulic excavators are designed and built, while Safe Work Australia's model Code of Practice for managing the risks of plant repeats the regulation 213 duty and recommends keeping a register of plant that needs regular inspection and maintenance. Completing the 250-hour minor service on time establishes the foundation of the cumulative service model, because every 500-hour and 1,000-hour service builds on tasks performed at this interval. Organisations that track service completion digitally in platforms such as MapTrack benefit from automatic hour-based scheduling, centralised compliance records and instant retrieval of service history when auditors, insurers or site managers require proof of maintenance.

Benefits of using this excavator 250-hour service procedure

  • Reduced breakdowns: regular oil, filter and fluid changes prevent engine and hydraulic failures that cause unplanned downtime on site.
  • Extended component life: clean oil and correct lubrication reduce wear on engine, hydraulic pump, final drives and undercarriage components.
  • Lower repair costs: a 250-hour service costs a fraction of an emergency breakdown repair. Catching issues early prevents cascading damage.
  • Operator safety: inspecting safety devices, structural components and hydraulic hoses at regular intervals reduces the risk of on-site incidents.
  • Compliance: documented service records demonstrate that equipment is maintained to WHS standards, supporting insurance and regulatory obligations.
  • Resale value: a complete service history with documented 250, 500 and 1,000-hour services increases the machine's value at trade-in or auction.

What to include in an excavator 250-hour service procedure

This excavator 250-hour service procedure covers 7 key areas:

  • Engine: drain and replace engine oil (15W-40), replace oil filter, inspect air filter, drain fuel/water separator, check coolant, inspect belts and hoses, clean radiator fins.
  • Hydraulic system: check hydraulic oil level, inspect hoses, fittings and cylinders for leaks, check quick-coupler.
  • Undercarriage / tracks: check and adjust track tension, inspect track pads, rollers, idlers and sprockets.
  • Lubrication: grease boom, arm and bucket pins, swing bearing, slew ring gear and track adjusters.
  • Electrical: check battery terminals and charge, test all lights.
  • Safety devices: test horn, reversing alarm and travel alarm, check seatbelt, fire extinguisher and ROPS/FOPS structure.
  • Structural: inspect boom, arm and bucket for cracks, check bucket teeth and cutting edge, verify all guards and covers.

How to use this excavator 250-hour service procedure

  1. Park the excavator on level ground, lower all attachments to the ground, engage the safety lock and shut down the engine. Allow the engine to cool before draining oil.: Position on firm, level ground away from traffic. Lower the bucket flat to the ground and engage the hydraulic safety lock lever. Allow at least 15 minutes for the engine to cool to prevent burns during oil draining.
  2. Record the equipment details and current hour meter reading at the top of the service procedure form.: Include the machine serial number, fleet ID, make, model, bucket size and site location. Cross-check the hour meter reading against the last service to confirm the 250-hour interval is correct.
  3. Start with the engine section: drain the old engine oil, replace the oil filter, fill with new oil to the correct level, then inspect the air filter, drain the fuel/water separator and check coolant.: Use 15W-40 CI-4 or CK-4 engine oil as specified by the manufacturer, typically 20 to 30 litres. Pre-fill the new oil filter before fitting. Inspect the outer air filter for damage and clean with compressed air if reusable. Drain the fuel/water separator bowl and check coolant level at the overflow tank.
  4. Check hydraulic oil level in the sight glass, inspect all hydraulic hoses and fittings for leaks, and check the quick-coupler.: The hydraulic oil level should be in the middle of the sight glass with the boom lowered and all cylinders retracted. Inspect all hoses for chafing, bulging or weeping fittings. Test the quick-coupler locking mechanism to confirm positive engagement.
  5. Inspect the undercarriage: check track tension and adjust if needed, inspect pads, rollers, idlers and sprockets for wear.: Measure track sag at the midpoint between the front idler and rear sprocket, typically 20 to 30 mm for a standard excavator. Adjust tension via the grease-type track adjuster if outside specification. Visually inspect pads for missing grousers and rollers for leaks.
  6. Grease all specified points: boom, arm and bucket pins, swing bearing, slew ring gear teeth and track adjusters. Use EP2 lithium complex grease.: Apply grease to each point until fresh grease is visible at the seal. Typical excavators have 12 to 20 grease points. Apply slew ring grease to the gear teeth using the open gear grease applicator. Do not over-grease sealed bearings.
  7. Check the battery, test all lights, test the horn and reversing alarm, check the seatbelt, fire extinguisher and ROPS/FOPS structure.: Inspect battery terminals for corrosion and tightness. Test all work lights, travel lights, indicators and beacon. Verify the horn and reversing alarm are audible at a minimum of 5 metres. Check the seatbelt for fraying, latch function and retraction.
  8. Start the engine and check for leaks, abnormal noises or warning lights. Check the oil pressure gauge and all instrument readings. Record any defects or recommendations in the notes section.: Run the engine to operating temperature and cycle all functions (boom, arm, bucket, swing, travel) at low speed. Walk around the machine checking for new fluid leaks. Confirm all gauges are within the normal range before signing off.
  9. Set the next service due hours (next 250-hour and next 500-hour intervals). Sign off and update the machine's maintenance log.: Calculate the next 250-hour and 500-hour service points from the current meter reading. Record due hours on the cab service sticker and in the fleet management system. Capture the technician name and trade certificate number.

How often should you complete this service procedure?

A 250-hour service should be performed every 250 engine hours, which typically equates to every 4 to 6 weeks of full-time operation. For excavators operating in severe conditions such as demolition, quarry or marine environments, consider shortening the interval to 200 hours. Machines working in particularly abrasive conditions like rock quarries or sandy river crossings may benefit from more frequent oil sampling at 125-hour intervals to monitor wear metal trends and catch contamination early. Daily pre-start checks by the operator should continue between service intervals to catch issues such as fluid leaks, damaged hoses or loose track components before they escalate. In MapTrack, set up meter-based maintenance triggers so the system automatically generates a work order as each excavator approaches its 250-hour threshold, ensuring no minor service is missed regardless of how many machines your fleet operates.

Frequently asked questions

A 250-hour excavator service is a minor service that includes draining and replacing engine oil (typically 15W-40), replacing the engine oil filter, inspecting or replacing the outer air filter, draining the fuel/water separator, checking coolant level, checking hydraulic oil level, inspecting belts and hoses, checking and adjusting track tension, greasing all boom, arm and bucket pins, greasing the swing bearing and slew ring, checking battery and electrical connections, testing safety devices (horn, reversing alarm, seatbelt), and inspecting structural components (boom, arm, bucket teeth, cutting edge). It takes approximately 1.5 to 2.5 hours.

Excavators follow a tiered service schedule based on engine hours. A 250-hour (minor) service covers oil, filters, grease and basic inspections. A 500-hour (intermediate) service adds hydraulic filter replacement, fuel filter replacement, undercarriage wear measurement and valve clearance checks. A 1,000-hour (major) service adds hydraulic oil change, coolant flush, final drive oil, injector and turbo inspection. Daily pre-start checks are performed by the operator before each shift. Always refer to the manufacturer service manual for your specific make and model.

Most excavator engines use 15W-40 diesel engine oil meeting CI-4 or CK-4 specifications. Typical engine oil capacity for a 10-35 tonne tracked excavator is 20-30 litres. Some manufacturers specify different grades for extreme cold or hot conditions. Always check the service manual for your specific make, model and operating environment.

The WHS Act 2011 and WHS Regulations 2011 (Chapter 5) require persons with management or control of plant to ensure it is maintained so it remains safe and without risk to health. This includes following the manufacturer service schedule and using competent personnel (regulation 213); documented records are good practice and the evidence that this was done. Safe Work Australia Codes of Practice for Managing Risks of Plant provide further guidance. Documented 250-hour service records with technician sign-off demonstrate compliance during audits and investigations.

Yes. This excavator 250-hour service checklist is completely free to download as a PDF with no signup or email required. It covers every task in the minor service interval including engine oil and filter replacement, grease points, hydraulic checks, track tension and safety device testing.
