MAINTENANCE INSTRUCTIONS
CAUTION: Neglecting proper maintenance can cause premature engine
component failures.
Initial Start-Up Maintenance
The initial start-up checks must be made before putting the engine into service.
Please refer to the Maintenance Schedule on page 37 and perform the initial start-up
operations in the sequence shown in column 1.
Routine Maintenance
Routine maintenance provides the best solution for making sure that the engine is ready
when you are. The following are some routine service points:
• Keep the fuel tank filled. A full tank of fuel reduces the possibility of condensation
forming in the fuel tank and moisture entering the fuel system.
• Make frequent checks for engine oil and coolant leaks
• Repair any oil or coolant leaks
• Check battery condition and cables frequently
• Keep the engine air filter and/or spark arrestor clean
• Monitor engine coolant temperature
• Monitor engine oil pressure
• Check voltmeter and charging system
• Monitor fuel pressure
Scheduled Preventive Maintenance
Refer to the Maintenance Schedule on page 37 to ensure that all of the maintenance
items listed are checked and replaced at the recommended hours.
Engine Oil Level Check
CAUTION: Do not operate the engine with the oil level below the bottom of
the dipstick or ‘Add’ mark on the dipstick, or above the top or ‘Full’ mark on the
dipstick.
The engine oil level should be checked daily. It is recommended that the oil be checked
just before the engine is started for the first time for the day. The oil level should be
between the ‘ADD’ and the ‘FULL’ marks on the dipstick.
