5-5: Machine Maintenance
ENGINE MAINTENANCE
Engine Oil Level Check
The engine oil level should be checked daily. It is recommended that the oil be checked
just before the engine is started for the rst time for that day. The oil level should be
between the ‘Add’ and the ‘Full’ marks on the dipstick. See next page for engine oil
recommendation.
Do not operate the engine with the oil level below the bottom of the ‘Add’ mark on
the dipstick, or above the top of the ‘Full’ mark.
Adding Engine Oil
It is normal to add some oil in the period of time between oil changes. The amount will
vary with the severity of operation. When adding or replacing engine oil, be sure the oil
meets or exceeds the recommended specication.
Changing Engine Oil and Filter
The engine oil and lter must be changed every 100 hours or every 3 months whichever
occurs rst. The oil and lter should be changed every 50 hours or less if the engine is
operating in dusty or extremely dirty areas, or during periods of high ambient temperature.
Engine Oil Quality
To achieve proper engine performance and durability, it is important that you use only
engine lubricating oils of the correct quality in your engine. Proper quality oils also provide
maximum eciency for crankcase ventilation systems, which reduces pollution.
Oil Filter
Kohler engines use Kohler oil lters. An equivalent or better oil lter must be used when
servicing the engine.
When removing the lter, due to it’s location and orientation, it is best loosen it completely
and allow to drain the for a small period of time. In one motion rotate the lter so it is
upright, then remove from engine area.
Clean the lter mounting base and lightly coat the gasket surface of the new lter with
engine oil. Hand tighten the lter until the gasket contacts the base, then tighten another
½ turn. Fill the engine with the correct amount of oil, run the engine and check for oil leaks
at the drain plug and oil lter gasket.
