will either activate a warning device or stop the engine
when the engine runs low on oil. (Read the operating
instructions supplied by the equipment manufacturer to
determine which way your engine is equipped because the
equipment manufacturer supplies the oil pressure gauge.)
See OIL PRESSURE on page 12 for oil filling instructions.
Periodically remove grass buildup under mower
deck. (See Maintenance.)
After engine has started, let it warm up several
seconds to several minutes, depending on outside
temperature.
