not operate unless they are functioning properly.
Operation
• Never run an engine in an enclosed area.
• Only operate in good light, keeping away from holes
and hidden hazards.
• Be sure all drives are in neutral and parking brake is
engaged before starting engine. Only start engine from
the operator’s position. Use seat belts if provided.
• Slow down and use extra care on hillsides. Be sure to
travel in the recommended direction on hillsides. Turf
conditions can affect the machine’s stability. Use
caution while operating near drop-offs.
• Slow down and use caution when making turns and
when changing directions on slopes.
• Never raise deck with the blades running.
• Never operate with guards not securely in place. Be
sure all interlocks are attached, adjusted properly, and
functioning property.
• Do not change the engine governor setting or overspeed
the engine.
• Stop on level ground, lower the cutting units, disengage

Toro Mower Safety
The following list contains safety information specific to
Toro products or other safety information that you must
know that is not included in the ANSI standards.
This product is capable of amputating hands and feet and
throwing objects. Always follow all safety instructions to
avoid serious injury or death.
Use of this product for purposes other than its intended use
could prove dangerous to user and bystanders.
• The grass deflector must always be installed and in the
lowest position on the side discharge cutting unit. Never
operate the mower without the deflector or entire grass
collector.
• If the cutting unit discharge area ever plugs, shut the
engine off before removing the obstruction.
• Cut grass slopes carefully. Do not start, stop, or turn
suddenly.
• Do not touch the engine or muffler while the engine is
running or soon after it has stopped because these areas
could be hot enough to cause burns.
Maintenance and Storage
• Check the blade mounting bolts frequently to be sure
that they are tightened to specification.
• Make sure that all hydraulic line connectors are tight
and all hydraulic hoses and lines are in good condition
before applying pressure to the system.
• Keep your body and hands away from pin hole leaks or
nozzles that eject hydraulic fluid under high pressure.
Use paper or cardboard, not your hands, to search for
leaks. Hydraulic fluid escaping under pressure can have
sufficient force to penetrate the skin and cause serious
injury.
Operation
• Know how to stop the machine and engine quickly.
• Always wear substantial shoes. Do not operate the
machine while wearing sandals, tennis shoes, or
sneakers.
• Wearing safety shoes and long pants is advisable and
required by some local ordinances and insurance
regulations.
• Fill fuel tank until level is 1 in. (25 mm) below the
bottom of the filler neck. Do not overfill.
• Before disconnecting or performing any work on the
hydraulic system, all pressure in the system must be
relieved by stopping the engine and lowering the cutting
units to the ground.
• If the engine must be running to perform a maintenance
adjustment, keep hands, feet, clothing, and any parts of
the body away from the cutting units, attachments, and
any moving parts. Keep everyone away.
• Do not overspeed the engine by changing governor
settings. To ensure safety and accuracy, have an
Authorized Toro Distributor check the maximum engine
speed with a tachometer.
4
• The engine must be shut off before checking the oil or
adding oil to the crankcase.
• Make sure that the mower fuel tank is empty if the
machine is to be stored in excess of 30 days. Do not
store the mower near any open flame or where gasoline
fumes may be ignited by a spark.
• Perform only those maintenance instructions described
in this manual. If major repairs are ever needed or if
assistance is desired, contact an Authorized Toro
Distributor.
Safety and Instruction Decals
Safety decals and instructions are easily visible to the operator and are located near any area
of potential danger. Replace any decal that is damaged or lost.
• To make sure of optimum performance and continued
safety certification of the machine, use only genuine
Toro replacement parts and accessories. Replacement
parts and accessories made by other manufacturers
could be dangerous, and such use could void the
product warranty.
