General Engine Maintenance

Detailed instructions and recommendations for break-in and
regular maintenance are specified in the Engine Owner's
manual. Please refer to this manual for engine servicing,
lubricating oil levels
recommendations, bolt torques, etc. The engine warranty is
backed by the engine manufacturer.

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 sitting level when checking oil. Refer to
engine manual and
recommendation and capacities.
IMPORTANT: Change the engine oil and filter after the
first 5 hours of operation and per the engine manufacturer's rec-
ommendations 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 precau-
tions to minimize oil spillage on the exhaust system.
Draining the engine oil:
1. Locate the oil drain valve on the engine. Figure 5-1
2. Position a suitable oil drain container under the machine
below the oil drain valve.
3. Twist the valve counterclockwise to open the valve.
Allow 10 minutes for engine oil to adequately drain.
4. After oil is drained, close the valve by twisting it
clockwise.
5. Clean up any spilled oil.
IMPORTANT: All oil drips or spills must be cleaned off
of the exhaust system before operating the machine.

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
5-2
These mowers are equipped with a safety filter. The filter
element slides over the safety filter. Figure 5-3
The safety filter does not require servicing unless it becomes
contaminated with dirt or moisture.

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
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.
Figure 5-2
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.
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.
