Retaining walls and drop-offs around steps and water are
a common hazard. Do NOT operate down slope towards or
near water, retaining walls, or drop-offs.
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 dropping over retaining
walls, edges, ditches, embankments, or into water can
cause rollovers, which may result in serious injury, death, or
drowning.
Overhead Obstacles
Check for overhead clearances before driving under any
objects. Do not allow the roll bar to contact low overhanging
obstacles such as tree branches and guide wires.
Fuel and Maintenance
NOTICE
Use ultra low sulfur fuel only.
Consult the engine manufacturer's manual for specific fuel
recommendations.
Always disengage all drives, shut off the engine, and remove
the key before doing any cleaning, refueling, or servicing.
Fuel and it's 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. Fuel spills
should be cleaned up promptly and before operation begins.
Fuel should be stored only in sealed containers approved for
fuel.
Proper maintenance is critical to the safety and performance
of your unit. Keep the unit free of grass, leaves, and excess
oil. Be sure to perform the maintenance procedures listed in
this manual, especially periodically testing the safety system.
Enclosed Areas
Only operate this unit outdoors and away from unventilated
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.
