How to Use This Checklist

  • **Prepare** — record the date conducted, who prepared the inspection, and the machine's location in the opening items.
  • **Ground-level walkaround** — inspect the lighting system (headlights, taillights and warning beacons), access components such as steps, handrails and grab irons, and the general condition and cleanliness of the undercarriage assembly.
  • **Exterior walkaround** — work through the brake system: filters and filter housing, lines and hoses, parking brake engagement, fluid levels and condition, and fittings and connection points. Check the routing and security of electrical and hydraulic lines, the hydraulic system (oil level, cylinder rods and seals, hoses and tubing, fittings and couplings), the fuel system (tank cap security and tank physical condition), lift arms, and the machine body's panels, frame and structural integrity.
  • **Fluids and leaks** — check grease line routing, condition and fittings, and inspect all systems for fluid leaks: engine, hydraulic, transmission and fuel.
  • **Attachments** — inspect the cutting edge of the work tool for wear and damage, the ground engaging tools (G.E.T.) components, and the condition and retention of bucket teeth.
  • **Wheeled machine components** — assess tire tread depth and wear pattern, valve stems and caps, and inflation pressure; check wheel rims for lug nut torque and tightness and for structural damage, cracks or deformation; and inspect axles and drive shafts for condition, play and lubrication.
  • **Tracked machine components** — inspect track roller condition and wear, idler wheel wear and alignment, sprocket tooth condition and wear pattern, and steel tracks (track shoe condition and fasteners, link pins, bushings and rail surface). For rubber tracks, check the track surface and tread, the torsion axle condition and alignment, and track tension adjustment and sag.
  • **Engine compartment** — check engine oil level, viscosity and contamination; radiator coolant level, condition and freeze point; the coolant recovery tank level and condition; transmission fluid level, colour and odour; the air filter element and restriction indicator; drive belt and cooling hose tension, cracks and wear; the battery's terminals, cleanliness and charge level; and the covers, guards and heat shielding.
  • **Cab exterior** — check the rotating beacon, strobe and work lights; wiper blades and washer fluid level; window glass integrity and mirror condition; and the integrity of the rollover protective structure (ROPS).
  • **Cab interior** — check the operator seat adjustment, belt and suspension; the fire extinguisher charge, seal and accessibility; horn functionality and sound output; interior and dome lighting; instrument panel gauges, switches and joystick controls; ROPS labelling and interior structure; seatbelt webbing, retractor and installation date; interior mirrors and window visibility from the operator position; and the backup alarm and audio warning systems.
  • **Close out** — complete the final review and record your findings in the inspection summary and documentation section so the machine's history is on file.

Why utility vehicle preventive maintenance matters

Heavy utility vehicles, construction equipment and industrial machinery are expensive assets whose condition changes with every shift. The purpose of a preventive maintenance inspection is to find wear, leaks, damage and faults while they are still minor, and to keep that judgement consistent whoever performs it. A structured inspection covers the whole machine — safety systems, fluids, tyres or tracks, braking, the engine compartment and the operator station — rather than only the part that most recently caused trouble. Run regularly, it gives you a clear record of what was checked, what condition it was in, and what was flagged for action.

What a preventive maintenance checklist covers

A useful checklist works from the ground up and from the outside in, and this one follows that order across 72 items: - **Ground-level walkaround:** lighting — headlights, taillights and warning beacons; access components such as steps, handrails and grab irons; and the general condition and cleanliness of the undercarriage assembly. - **Exterior walkaround:** the brake system (filters and filter housing, lines and hoses, parking brake engagement, fluid levels and fittings); routing and security of electrical and hydraulic lines; the hydraulic system (oil level, cylinder rods and seals, hoses and tubing, fittings and couplings); the fuel system (tank cap security and tank condition); lift arms; and the machine body's panels, frame and structural integrity. - **Leaks and lubrication:** inspection for fluid leaks across engine, hydraulic, transmission and fuel systems, and grease line routing, condition and fittings. - **Attachments:** cutting edge wear and damage, ground engaging tools (G.E.T.), and bucket teeth condition and retention. - **Wheeled machines:** tyre tread depth and wear pattern, valve stems and caps, inflation pressure, lug nut torque, rim damage, and axle and drive shaft condition, play and lubrication. - **Tracked machines:** track rollers, idler wheels, sprocket teeth, track shoes and fasteners, link pins, bushings, rail surface, plus rubber track surface, torsion axles and track tension. - **Engine compartment:** engine oil, radiator coolant and recovery tank, transmission fluid, air filter and restriction indicator, drive belts and cooling hoses, battery terminals and charge, and covers, guards and heat shielding. - **Cab exterior:** beacon, strobe and work lights; wiper blades and washer fluid; glass and mirrors; and the integrity of the rollover protective structure (ROPS). - **Cab interior:** seat adjustment, belt and suspension; fire extinguisher charge, seal and accessibility; horn; interior and dome lighting; gauges, switches and joystick controls; ROPS labelling; seatbelt webbing, retractor and installation date; mirrors and visibility; and the backup alarm and audio warnings. - **Close-out:** a final review followed by an inspection summary and documentation entry.

How to use the checklist

Work through the sections in the order given: 1. Record the date conducted, who prepared the inspection, and the location. 2. Carry out the ground-level and exterior walkarounds before opening or climbing on the machine. 3. Inspect the machine-specific, wheeled and tracked components relevant to the unit you are working on. 4. Open the engine compartment and check fluids, filters, belts, hoses, battery and guarding. 5. Inspect the cab from the outside in, covering lights, glass, mirrors, ROPS, then the seat, restraints, extinguisher, controls and warning systems. 6. Review your findings, and record the inspection in the summary and documentation section. Each item uses the same answer scale: **Pass – No Issues Found**, **Pass – Minor Wear Noted**, **Fail – Action Required**, and **Not Applicable**. Where a defect is found, the standard route is to mark it Fail – Action Required and pass the machine or component to the relevant person for repair before it returns to service.

Get more out of your inspection

- Walk the machine in a fixed direction so no component is skipped. - Record minor wear honestly: 'Pass – Minor Wear Noted' builds a wear history you can compare against next time. - Treat the fluid and leak checks as one pass — a leak is easier to trace when you have just looked at the levels. - Match the tracked or wheeled section to the machine in front of you and mark items Not Applicable where the component does not exist, rather than leaving them blank. - Keep the completed inspection with the machine's records so trends are visible over time.

Frequently Asked Questions

Most of the items in this checklist use a four-point scale: Pass – No Issues Found, Pass – Minor Wear Noted, Fail – Action Required, and Not Applicable.

The checklist groups its items into the ground-level walkaround, the exterior walkaround, machine-specific components, wheeled machine components, tracked machine components, the engine compartment and its components, the operator cab and its exterior and interior components, and final review, summary and documentation.

Yes. You record the date conducted, who prepared it, and the location at the start, and the checklist closes with a final review, inspection summary, and documentation section.

Mark the item Fail – Action Required, and pass the machine or component to the relevant person for repair before it returns to service.
