for use and such illegal use could cause equipment failure and
pose a fire hazard. Refer to the engine owner’s manual for fuel
specification requirements.
A fuel shut-off valve is located on each mower. Close the fuel
valve to prevent fuel flow to the engine. The valve’s two other
positions will allow fuel to be drawn from either one or the other
fuel tank.

Engine Oil and Filter
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 schedule for oil
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.
Draining the engine oil:
1. Locate the oil drain valve on the engine. Figure 4-5,
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. Once the valve is closed, 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.

These mowers are equipped with a safety filter. The filter
element slides over the safety filter.
Figure 4-7
The safety filter does not require servicing unless it becomes
contaminated with dirt or moisture.
Figure 4-4
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.
