MAINTENANCE TASKS
Daily Walk Around Inspection
Daily walk around inspection must be performed when the unit is operated continuously for extended periods of time.
Look for conditions that could hinder performance or safety, such as leaking oil, coolant, or gas (NG or propane);
blocked vents, loose or missing hardware, and bad electrical connections. Check for foreign matter blocking the
vents, the radiator and exhaust areas, and on top of the unit.
When the unit is not running, perform the following inspections:
• Inspect fan belt for cracks, fraying, and stretching. Ensure fan belt is properly inserted in the pulley grooves.
• Check fuel system, engine oil, and coolant.
• Inspect the tire pressure.
• Check electrical connectors, battery and battery disconnect connections, and ground points. Look for loose or
missing hardware.
• Check all flexible rubber hoses for deterioration.
Engine Oil
At all times, the engine oil dipstick should measure between FULL and ADD. See Engine Oil Recommendations for
more information.
About the Engine Oil Replenishment System
This unit contains an engine oil replenishment system. The system eliminates the need for frequent filling and checking
of the crankcase. The system consists of a 21 gallon (79.5L) oil reservoir tank and an oil level regulator. The regulator
is mounted so the centerline of the sight glass is at the same height as the level of the oil in the crankcase. When
the engine oil level is low, the float triggers the reservoir tank to send fresh oil to the crankcase. The oil level regulator
delivers the amount of oil required to maintain a constant oil level in the crankcase. A fine mesh screen in the regulator
provides protection against damage by contaminants and abrasive foreign matter.
The regulator is pre-set to the appropriate level at the factory and should not require adjustment.
