Why Maintenance Matters

Proper maintenance is the difference between equipment that runs 20,000+ hours and machines that fail prematurely. Regular maintenance:

• Reduces unplanned downtime by up to 70%
• Extends equipment life by 25-40%
• Maintains resale value
• Prevents costly major repairs
• Ensures operator safety

Daily Inspection Checklist

Complete these checks before starting any equipment:

Walk-Around Inspection

• [ ] Check for fluid leaks (oil, coolant, hydraulic)
• [ ] Inspect tires/tracks for damage and proper inflation/tension
• [ ] Look for loose or missing bolts and pins
• [ ] Check mirrors and glass for damage
• [ ] Inspect bucket teeth and cutting edges
• [ ] Verify all guards and covers are in place

Fluid Levels

• [ ] Engine oil level
• [ ] Coolant level (check when cold)
• [ ] Hydraulic oil level
• [ ] Fuel level
• [ ] DEF level (diesel exhaust fluid)

Safety Systems

• [ ] Test horn
• [ ] Check all lights (head, tail, work, warning)
• [ ] Test backup alarm
• [ ] Verify seatbelt function
• [ ] Check fire extinguisher

Operational Checks

• [ ] Start engine and check for unusual sounds
• [ ] Verify all gauges read normal
• [ ] Test all hydraulic functions
• [ ] Check brake operation
• [ ] Test emergency stop

Weekly Maintenance Tasks

Lubrication

• [ ] Grease all fittings per manufacturer schedule
• [ ] Check pivot points for proper lubrication
• [ ] Inspect grease points for damage

Filters and Air System

• [ ] Check air filter restriction indicator
• [ ] Clean air filter housing
• [ ] Inspect air intake hoses for cracks

Undercarriage (Tracked Equipment)

• [ ] Check track tension
• [ ] Inspect rollers, idlers, and sprockets for wear
• [ ] Look for track link damage
• [ ] Check track shoe bolt torque

Belts and Hoses

• [ ] Inspect belts for cracks, fraying, glazing
• [ ] Check coolant hoses for soft spots or cracks
• [ ] Inspect hydraulic hoses for wear or damage

Monthly Maintenance Tasks

Battery

• [ ] Clean battery terminals
• [ ] Check battery hold-downs
• [ ] Test battery charge
• [ ] Inspect cables for corrosion

Cooling System

• [ ] Clean radiator fins
• [ ] Check coolant concentration
• [ ] Inspect fan blades for damage
• [ ] Check thermostat operation

Hydraulic System

• [ ] Check hydraulic oil condition
• [ ] Inspect cylinders for leaks or scoring
• [ ] Check pump operation
• [ ] Verify correct system pressure

Electrical System

• [ ] Test all switches and controls
• [ ] Check wiring for damage
• [ ] Test safety interlock systems
• [ ] Verify instrument accuracy

Seasonal Maintenance

Spring Checklist

• Change to summer-weight oils if applicable
• Remove any antifreeze additives
• Service AC system before hot weather
• Check tire/track condition after winter

Fall/Winter Prep Checklist

• Switch to winter-weight oils in cold climates
• Check coolant antifreeze protection level
• Verify block heater operation
• Service fuel system with winter additives
• Check battery cold cranking amps
• Test cab heater and defroster

Equipment-Specific Checklists

Excavators

• Swing bearing lubrication and inspection
• Boom and arm cylinder inspection
• Track adjustment
• Bucket pin and bushing wear

Wheel Loaders

Maintenance Record Keeping

Proper documentation protects your investment and maximizes resale value.

What to Track

• Date and hour meter reading for all services
• Type of service performed
• Parts replaced with part numbers
• Fluids used with specifications
• Technician name or company
• Any issues noted during inspection

Benefits of Good Records

• Proves maintenance history for resale
• Helps predict future maintenance needs
• Identifies recurring problems
• Supports warranty claims
• Assists with fleet management decisions

Common Problems and Solutions

Problem: Excessive Hydraulic Heat

Causes: Low oil level, dirty oil, clogged filter, worn pump

Solutions: Check level, change filter, test oil condition, have pump tested

Problem: Black Exhaust Smoke

Causes: Dirty air filter, fuel injection issues, turbo problems

Solutions: Replace air filter, check fuel system, inspect turbocharger

Problem: Undercarriage Wear

Causes: Incorrect track tension, operating in abrasive conditions, poor technique

Solutions: Adjust tension, train operators, consider different track type

Problem: Electrical Issues

Causes: Corroded connections, damaged wiring, weak battery

Solutions: Clean connections, repair wiring, test/replace battery
