Pre-trip inspection
Every shiftDo this walkaround at the start of every shift, machine parked on level ground, blade and ripper down, engine off. Don't start the machine until it's done. Anything affecting safe operation gets tagged out and reported before it moves.
Before you approach
- Work area around the machine — people, vehicles, overhead lines, trench edges, soft or sloped ground
- Ground under the machine — fresh oil, coolant, fuel or hydraulic puddles
- Steps, handholds, platforms — secure, clean, free of mud, ice, snow and grease
- Guards, covers, doors, latches — in place, undamaged, closed
- Housekeeping — trash, dirt and grease build-up cleared from engine area and undercarriage
Blade, ripper and push arms
- Cutting edge, end bits, corner bits — wear, cracks, loose or missing bolts
- Moldboard and blade structure — cracks, bent plates, weld damage
- Push arms, trunnions, brace links — cracks, loose bolts, pin play, clearance
- Lift, tilt and angle cylinders — leaks at seals, scored or bent rods, hose chafe
- Ripper frame, shanks, tips — wear, cracks, missing tips, pins and retainersIf equipped
- Front hydraulic hoses and fittings — chafe, weeping, bulges, damage
- Grease points on blade and ripper linkage — greased per the lube chart
Undercarriage and final drives
- Track sag / tension — within spec, adjust if slack or overtight
- Track shoes, links, pins, bushings — wear, cracks, missing or loose bolts
- Rollers, idlers, carrier rollers, sprockets — leaks, wear, damage, mounting and segment bolts
- Final drives and duo-cone seals — leaks, cover bolts, debris wrapped around the drive
- Track roller frames, guards, guides — cracks, damage, packed mud or debris
- Pivot shaft and equalizer bar — leaks, loose hardware, end pin play
Engine compartment and fluids (engine off)
- Engine oil level — level on dipstick, condition
- Coolant level — level in expansion tank; never open a hot system
- Hydraulic oil level — level in sight glass, implements down, engine off
- Transmission / power train oil level — level, condition, no sign of contamination
- Fuel level, fuel cap, water separator — enough fuel for the shift, cap sealed, drain water
- DEF level — level, cap sealed, no crystal build-upIf equipped
- Air cleaner restriction indicator — not tripped; reset or service if flagged
- Belts and hoses — tightness, cracks, leaks, chafe
- Radiator, oil cooler, aftercooler — debris, fin blockage, leaks, damaged fins and tubes
- Batteries and disconnect switch — secure, terminals clean and tight, no corrosion
- Leaks anywhere in the engine bay — oil, fuel, coolant, hydraulic
Lights, safety devices and exterior
- Work lights and beacon — working, lenses intact and clean
- Mirrors and cameras — intact, clean, adjusted
- Windows and glass — cracks, clean, unobstructed view
- Fire extinguisher — charged, mounted, inspection tag current
- Decals and warning labels — present, legible
- ROPS / FOPS and cab mounts — damage, cracks, loose mounting bolts
In the cab (before start)
- Seat and seat belt — condition, buckle latches, mounting secure, adjusted so pedals reach
- Controls and parking brake — transmission in NEUTRAL, implements in HOLD, parking brake set
- Cab floor and pedals — clear of tools, mud and debris
- Wipers and washers — working, washer fluid topped up
- Heater, defrost, AC — working (visibility in all conditions)
- Emergency exit and hammer — present, accessible, unobstructed
- Operator's manual and inspection log — in the cab
- Hour meter reading — recorded on this sheetRecord
Function check (engine running)
- Start-up — no abnormal noise or smoke, warning lights clear after self-test
- Gauges and monitor — readings normal, no active fault codes
- Horn, backup alarm, camera — all working
- Blade and ripper functions — smooth, no drift, holds position, no abnormal noise
- Travel and steering, both directions — tracks respond evenly, machine tracks straight
- Service and parking brakes — hold on a grade, brake test done before moving off
- Leaks after pressure is up — recheck cylinders, hoses, pumps and valve bank

Every 500 hours on the hour meter.
