SECTION 4: OPERATING YOUR Z-SERIES
WARNING: Read, understand, and follow
all instructions and warnings on the

Gas and Oil Fill-Up
Service the engine with gasoline and oil as instructed in
the separate engine manual packed with your mower.

Never fuel machine indoors or while the
engine is hot or running. Extinguish
cigarettes, cigars, pipes, and other
sources of ignition.
