Operator Safety
Fuel and Maintenance
Always disengage all drives, shutoff the engine, and 
remove the key before doing any cleaning, refueling, or 
servicing.
Gasoline and its vapors are extremely flammable. Do not 
smoke while operating or refueling. Do not add fuel while 
engine is hot or running. Allow engine to cool for at least 3 
minutes prior to adding fuel. 
Do not add fuel indoors, in an enclosed trailer, garage, 
or any other enclosed area that is not well ventilated. 
Gasoline spills should be cleaned up promptly and before 
operation begins. 
Gasoline should be stored only in sealed containers 
approved for fuel.
Proper maintenance is critical to the safety and perfor-
mance of your unit. Keep the unit free of grass, leaves, 
and excess oil. Be sure to perform the maintenance proce-
dures listed in this manual, especially periodically testing 
the safety system.
Retaining Walls, Drop-Offs, and Water
Retaining walls and drop-offs around steps and water are a common hazard. Give yourself a minimum of two mower 
widths of clearance around these hazards and hand-trim with a walk behind mower or string trimmer. Wheels drop-
ping over retaining walls, edges, ditches, embankments, or into water can cause rollovers, which may result in serious 
injury, death, or drowning.
Enclosed Areas
Only operate this unit outdoors and away from unventi-
lated areas such as inside garages or enclosed trailers. 
The engine emits poisonous carbon monoxide gas and 
prolonged exposure in an enclosed area can result in 
serious injury or death.
