Engine Oil and Filter

WARNING
If the engine has been running and is up to operating tem-
perature, allow the engine to cool before changing the oil.
Engine and engine oil will be very hot, so be very careful
when changing oil and wear the appropriate protective
gear to avoid being burned or exposed to engine oil.
Check engine oil daily and after every 4 hours of operation.
Machine must be setting level when checking oil. Refer to
engine manual and maintenance
recommendation and capacities.
Change the engine oil and filter after the first 5 hours of
operation and per the engine manufacturer's recommendations
after that. If mower is being operated in extremely dirty
conditions, then it is recommended oil be changed more
frequently. IMPORTANT: When removing the oil filter take
precautions to minimize oil spillage on the exhaust system.
The oil filter and oil drain plug are located on the underneath
side of the engine Figure 4-8

Engine Air Filter

Perform engine air filter maintenance per the Maintenance
Schedule shown elsewhere in this manual.
A specially designed dry filter is standard equipment on these
mowers and supplies clean combustion air to the engine. Figure
4-9
These mowers are equipped with a safety filter. The filter
element slides over the safety filter. Figure 4-10
The safety filter does not require servicing unless it becomes
contaminated with dirt or moisture.
Recommended service procedure
1. Release clamps and remove element. Clean the canister
with a damp cloth.
2. Before installing a new element, inspect it by placing a
bright light inside and rotating the element slowly,
looking for any holes or tears in the paper. Also check

Overservicing
Overservicing occurs when an air filter element is removed
for cleaning or replacement before it is necessary. Each time the
filter is removed a small amount of dirt and dust could fall in the
intake system. This accumulated dirt can cause a dusted engine.
It only takes a few grams of ingested dirt over the normal
service life of an engine to cause a dusted engine.
Do not clean the element, but replace with a new element
only. Cleaning used air filter elements, through improper
cleaning procedures, can get dust on the inside of the filter
causing dirt ingestion and engine failure.

gaskets for cuts or tears. Do not attempt to use a damaged
element which will allow abrasive particles to enter the
engine.
3. Reinstall the dust cap. Make sure it seals all the way
around the air cleaner body, then tighten the clamps.

4. Check all fittings and clamps periodically for tightness
and inspect hoses for holes or cracks.
5. Periodically check the intake hose for signs of ingested
dust. Locate and repair the source of ingested dirt.
6. Never operate the machine without an air filter installed.
