3. Use a 10 mm wrench or socket and open the valve
approximately 4 turns in the counterclockwise direc
-
tion. Allow 10 minutes for engine oil to adequately
drain.
4. After oil is drained, close the valve by turning it in the
clockwise direction until it is fully closed.
5. Once the valve is closed, clean up any spilled oil.
IMPORTANT: All oil drips or spills must be cleaned off
of the engine plate, engine exhaust system, and muf -

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

Recommended Service Procedure
1. Release clamps and remove the filter element. Clean
the air cleaner canister with a damp cloth.
2. Before installing a new filter element, place a bright
light inside the filter and rotate slowly to check for any
holes or tears in the paper. Also check gaskets for cuts
or tears. Do not attempt to use a damaged element
which will allow abrasive particles to enter the engine.
3. Install the top of the air filter cover. Make sure it seals
all the way around the lower part of the housing, then
tighten the clamps.
4. Never operate the machine without an air filter
installed.
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 filter element, 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.
It is important to note that whenever an air filter element is
cleaned by any method, the person or company performing
the cleaning assumes responsibility for the integrity of the
filter from then on.
The warranty for air filters expires upon
