Short answer

A cherry picker 500-hour service checklist records the intermediate service on a boom-type EWP: fluids, filters, hydraulic oil sampling, boom pin and bush wear, slew ring bolt torque, load indicator checks, outriggers and batteries. The model's manual sets which tasks fall due at 500 hours and any earlier calendar limit. AS 2550.10:2025 Section 6 covers maintenance, inspection and repair of mobile elevating work platforms.

Key takeaways

  • The MapTrack cherry picker 500-hour service checklist contains 22 checks across 9 sections. Sections covered: Engine (additional to 250-hour), Hydraulic System (additional to 250-hour), Boom Structure (additional to 250-hour), Slew System (additional to 250-hour), Wire Ropes / Chains (if fitted), Load Moment Indicator (if fitted), Outriggers (additional to 250-hour), Electrical (additional to 250-hour), Cab (additional to 250-hour).
  • Where the manual sets a 500-hour tier, include the earlier-tier tasks due at the same service and observe any calendar limit.
  • Torque-check slew ring bolts with a calibrated wrench to the manufacturer's figure; repeated loosening needs a competent person's investigation.
  • Measure and record boom pin and bush wear each time so wear rates show before play becomes unsafe.
  • Hour-based servicing sits alongside the inspections AS 2550.10:2025 Section 6 covers, including the major inspection described in EWPA guidance.

What is a cherry picker 500-hour service checklist?

A 500-hour service is the intermediate tier of scheduled preventive maintenance for a cherry picker (elevated work platform, boom lift or truck-mounted EWP). It is performed every 500 engine hours, which typically equates to every 8 to 16 weeks of regular use depending on utilisation. The 500-hour service carries forward all 250-hour tasks (engine oil and filter change, grease points, fluid level checks, boom structure inspection, safety device testing, tyre checks, platform inspection) and adds more in-depth maintenance. Additional tasks include replacing the fuel filter element, replacing the outer air filter element, testing coolant concentration, replacing hydraulic return and pilot filters, taking a hydraulic oil sample for laboratory analysis, measuring boom pin and bush wear, inspecting wire ropes or chains (if fitted), checking slew ring bolt torque, testing the load moment indicator calibration, inspecting the outrigger structure for cracking, load testing the battery, cleaning earth straps and servicing the cab A/C system. A qualified EWP technician or mechanic typically completes this service in 3 to 4 hours.

The 500-hour service addresses components beyond the scope of the basic 250-hour checks. At this interval, hydraulic oil has been in service long enough for contamination to build, and boom pivot points, slew bearings and outrigger components have been subjected to thousands of loading cycles. In Australia, EWPs are designed to AS/NZS 1418.10, maintained and inspected in line with AS 2550.10 Section 6, and must be maintained under the WHS Regulations 2011.

Benefits of using this cherry picker 500-hour service checklist

  • Early fault detection: hydraulic oil sampling at 500 hours catches contamination, metal particles and moisture before they damage pumps and valves.
  • Structural integrity: measuring boom pin and bush wear, checking slew ring bolt torque and inspecting for structural cracking ensures the machine remains safe for elevated work.
  • Extended component life: replacing hydraulic and fuel filters on schedule prevents contamination from cascading through the system.
  • Reduced breakdowns: detailed inspections of wire ropes, outrigger structure and load moment indicator calibration prevent performance degradation and unplanned downtime.
  • Compliance: documented service records at each interval demonstrate that equipment is maintained to WHS standards, AS 2550.10 and manufacturer specifications.
  • Resale value: a complete service history with documented 250, 500 and 1,000-hour services increases the machine's value at trade-in or when returning hire equipment.

What to include in a cherry picker 500-hour service checklist

This cherry picker 500-hour service checklist covers 9 key areas:

  • Engine: replace fuel filter element, replace outer air filter element, test coolant concentration (refractometer), adjust fan belt tension.
  • Hydraulic system: replace hydraulic return filter, replace hydraulic pilot filter (if fitted), take hydraulic oil sample for laboratory analysis.
  • Boom structure: measure boom pin and bush wear (mm), check for cracking at weld joints, inspect fly boom slide pads or wear strips.
  • Slew system: check slew ring bolt torque to manufacturer specification, inspect slew gear teeth for wear.
  • Wire ropes / chains: inspect wire ropes or lifting chains (if fitted) for broken strands, corrosion, kinking or stretch.
  • Load moment indicator: test LMI calibration and function (if fitted).
  • Outriggers: inspect outrigger beams and cylinders for cracking, bending or hydraulic leaks.
  • Electrical: test battery load (CCA), clean and tighten all earth straps.
  • Cab: check and clean A/C condenser, test A/C operation and refrigerant.

How to use this cherry picker 500-hour service checklist

  1. Complete the full 250-hour service procedure first (engine oil and filter change, grease points, fluid level checks, boom inspection, safety device testing, tyre checks, platform inspection). Use the 250-hour service checklist.: Verify all 250-hour items are completed and any defects documented before proceeding to the 500-hour specific tasks. The cumulative service model requires all lower-tier items to be done first.
  2. Replace the fuel filter element. Drain any trapped fuel from the filter housing before fitting the new element.: Place a drip tray under the filter housing. Open the drain valve to remove trapped fuel, then unscrew the filter bowl and replace the element. Prime the fuel system by cranking with the fuel shut-off open until fuel pressure builds. Check for leaks before proceeding.
  3. Replace the outer air filter element. Inspect the inner safety element and replace only if visibly damaged or due at 1,000 hours.: Remove the outer element carefully to prevent debris from entering the intake. Inspect the inner safety element for tears, holes or damaged seals. The inner element is typically replaced at the 1,000-hour service unless visibly compromised.
  4. Replace the hydraulic return filter and pilot filter (if fitted). Take a hydraulic oil sample from the return line for laboratory analysis before installing new filters.: Collect the oil sample from the return line sample port using a clean bottle while the system is at operating temperature. Label the sample with the machine fleet ID, date and hours. Replace both the return and pilot filters with genuine or OEM-equivalent elements.
  5. Measure boom pin and bush wear at all major pivot points. Record measurements for trend comparison against previous services.: Use a dial indicator or feeler gauge to measure radial play at each boom pin and bush. Compare readings to the manufacturer wear limits and to previous 500-hour service data. Excessive play in boom pins is a serious safety concern and must be rectified before the machine is returned to service. Also inspect fly boom slide pads or wear strips and replace if worn beyond limits.
  6. Check slew ring bolt torque to manufacturer specification. Inspect slew gear teeth for wear or damage.: Using a calibrated torque wrench, check a sample of slew ring bolts (minimum 25% or as specified by the manufacturer). Record any bolts found below specification and re-torque. Inspect the slew gear teeth for pitting, chipping or uneven wear patterns. Lubricate the slew ring gear teeth if required by the maintenance schedule.
  7. Inspect wire ropes or chains (if fitted) for broken strands, corrosion, kinking or stretch. Test the load moment indicator calibration.: For machines with wire rope extension systems, inspect the full length of each rope for broken wires, corrosion, bird-caging or kinking. For chain-equipped machines, check for stretch by measuring the pitch over 10 links. Test the LMI by operating the boom at various radii and confirming the display readings match the load chart.
  8. Load test the battery (CCA). Clean and tighten all earth straps. Inspect outrigger beams and cylinders for cracking or damage.: Use a digital battery tester to measure cold cranking amps (CCA) and compare to the battery rating. A reading below 75% of the rated CCA indicates the battery should be replaced. Clean terminals with a wire brush and apply terminal protector spray. Inspect all outrigger beams for cracking, bending and weld integrity. Check outrigger cylinders for hydraulic leaks and rod scoring.
  9. Start the engine and check for leaks, abnormal noises or warning lights. Record any defects or recommendations in the notes section. Set the next service due hours and sign off.: Run the engine to operating temperature and cycle all functions including boom extension, slew and outrigger deployment. Walk around the machine checking for new fluid leaks. Confirm all gauges are within the normal range. Set the next 250-hour, 500-hour and 1,000-hour due points and sign off.

How often should you complete this service procedure?

A 500-hour service should be performed every 500 engine hours, which typically equates to every 8 to 16 weeks of regular cherry picker use. The service carries forward all 250-hour tasks. For machines operating in harsh conditions such as construction sites, coastal environments or high-dust areas, consider shortening the hydraulic filter interval and performing oil sampling and boom pin measurement more frequently. In MapTrack, set up meter-based maintenance triggers at 250-hour and 500-hour intervals so work orders are generated automatically as each machine approaches its service point.

For cherry pickers in high-utilisation hire fleets, the 500-hour service is a key checkpoint that directly affects customer satisfaction and equipment availability. In MapTrack, meter-based scheduling automates service triggers across your fleet.

Frequently asked questions

A 500-hour cherry picker service is an intermediate service that carries forward all 250-hour tasks (engine oil and filter, grease points, fluid level checks, boom inspection, safety device testing, tyre checks, platform inspection) and adds fuel filter replacement, outer air filter replacement, coolant concentration testing, hydraulic return and pilot filter replacement, hydraulic oil sampling for analysis, boom pin and bush wear measurement, slew ring bolt torque check, wire rope or chain inspection, load moment indicator calibration testing, outrigger structural inspection, battery load testing, earth strap cleaning and A/C condenser service. It takes approximately 3 to 4 hours.

Boom pins and bushes carry the full load of the platform, operator and any materials being lifted. Worn pins allow excessive play in the boom, which can cause unpredictable boom movement, reduced structural integrity and accelerated wear of surrounding components. Measuring pin wear at 500-hour intervals lets you track wear rates, forecast replacement timing and catch unsafe conditions before they put operators at risk. Excessive boom pin play is a common reason for EWP failure in service.

Hydraulic oil sampling at the 500-hour interval allows you to detect contamination, metal particles or moisture in the hydraulic system before they cause pump or valve damage. Laboratory analysis reports on particle count, viscosity, water content and wear metals. For cherry pickers working in dusty construction environments or coastal conditions, consider sampling at every 250-hour service. The analysis results help you decide whether the hydraulic oil can continue to the 1,000-hour full change or needs early replacement.

Cherry picker (EWP) maintenance in Australia is governed by the WHS Act 2011 and WHS Regulations 2011. AS/NZS 1418.10 covers the design, construction and verification of mobile elevating work platforms specifically, including the maintenance information supplied for use, and AS 2550.10 Section 6 covers in-service maintenance, inspection and repair. AS 2550 provides crane and EWP safe use requirements. The WHS Regulations require plant to be maintained in accordance with manufacturer recommendations (regulation 213), and the Code of Practice for managing the risks of plant calls keeping maintenance records good practice for plant that is not registered.

The 250-hour service covers routine items: engine oil and filter change, greasing all points, checking fluid levels, boom structure visual inspection, safety device testing, tyre checks, platform guardrail inspection and a functional test. The 500-hour service carries forward all 250-hour tasks and adds fuel filter replacement, outer air filter replacement, coolant concentration testing, hydraulic filter replacement and oil sampling, detailed boom pin and bush wear measurement, slew ring bolt torque check, wire rope or chain inspection, LMI calibration testing, outrigger structural inspection, battery load test, earth strap cleaning and A/C service.

Loose slew ring bolts can allow the turntable to move relative to the chassis, causing unpredictable boom movements and potentially catastrophic structural failure. Slew ring bolt torque should be checked at every 500-hour service using a calibrated torque wrench. If any bolts are found below the manufacturer specification, re-torque all bolts in the correct sequence and investigate the root cause. Repeated loosening may indicate the slew ring or mounting surface requires further inspection by a structural engineer.
