IMPORTANT: When removing the oil filter take precautions to
minimize oil spillage on the engine plate, engine exhaust
system, and muffler guard.
Draining the Engine Oil:

2. Position a suitable oil drain container under the
machine below the oil drain valve.

clockwise.

All oil drips or spills must be cleaned off of the engine
plate, engine exhaust system, and muffler guard before
operating the machine.
Engine Air Filter
These mowers come equipped with two different styles of
air filters; integrated or canister. The required servicing for
these two filter types is different from one to the other. Refer
to the following for the one appropriate for your mower.
Integrated Type
Perform engine air filter maintenance per the Maintenance
Schedule shown elsewhere in this manual. Figure 4-10

A specially designed dry filter is standard equipment on
these mowers and supplies clean combustion air to the
