•Run Pretrip Test (see “Performing a Pretrip Test”).
Engine:
•Check fuel supply.
•Check engine oil level.
• • • Listen for unusual noises, vibrations, etc.
• • • Inspect belt for condition and proper tension.
• • • Check engine oil pressure hot, on high speed (should display “OK”).
• • • Check engine coolant level and antifreeze protection (-30 F [-40 C]).
• • • Drain water from the Primary fuel filter bowl.
• • Drain water from fuel tank and check vent.
• • Inspect/clean screen in banjo fitting on hand fuel pump.
•Check engine mounts for wear.
•Replace EMI 3000 air cleaner element (see “EMI 3000 Air Cleaner”) at 3,000
hours or two years (whichever occurs first). See note.
•Replace EMI 3000 fuel filter/water separator. See note.
•
Change engine oil and oil filter (hot). Requires oil with API Classification CJ-4 or
CK-4. See Note*.NOTE: For high biodiesel use (B20) the engine oil and
filter should be changed every 1500 hours.
•Adjust engine valve clearance.
Change ELC (red) engine coolant every 5 years or 12,000 hours. Units
equipped with ELC have an ELC nameplate on the expansion tank (see “Engine
Cooling System”).
Electrical:
• • Inspect battery terminals and electrolyte level.
• • Inspect wire harness for damaged wires or connections.
• • Inspect AC generator wire connections for tightness.
Structural:
• • • Visually inspect unit for fluid leaks.
• • • Visually inspect unit for damaged, loose, or broken parts.
• • Clean entire unit including radiator coil.
• • Check all unit and fuel tank mounting bolts, brackets, lines, hoses, etc.
