ENGINE OIL
Check the engine oil each day before starting the
engine. If the oil level is low, remove the oil filler cap
and add oil as required (Figure 3D-3).
Figure 3D-3. Engine Oil Filler Cap and Filter
Perform an initial oil and filter change after the first 50
hours of operation and every 200 hours thereafter.
Refer to the engine manual for additional information
and instructions.
Use engine oils with API classification CD/CE.
See the Parts & Maintenance manual for engine break-
in information.
AIR CLEANER
The air cleaner assembly is mounted above the engine
and to the rear of the operator’s seat. An evacuator
valve on the air cleaner cover traps sediment for dis-
posal. A filtered air hose extends from the air cleaner to
the engine intake. A fresh air intake hose extends back
to the air intake port above the radiator (Figure 3D-4).
Figure 3D-4. Air Cleaner Assembly Location
The cyclonic action of air moving through the air
cleaner deposits dust and dirt into a rubber dust evacu-
ator. The dust evacuator then dumps the debris. The
valve should be checked daily for contaminants.
Squeeze the sides of the valve together to release
debris trapped inside.
